2018 LEAF; One Month!

Yesterday was a very strange day.  First my weekend plans were canceled at the last second so I decided it was time to see if my new EVSE worked. I had actually not even looked at it yet.  So I grabbed the bag, took it out, removed the plastic and noticed it is heavier than previous versions so apparently Nissan beefed it up to handle 240 volts maybe?

So I started browsing Plugshare and first time I realized; There are hardly any 14-50 plugs around outside of campgrounds.  Most campgrounds were closed or charge a hefty fee for entry.

So after driving around the neighborhood including Pacific Raceway which was supposed to have several, I couldn't find any and couldn't figure out how to get behind the grandstand so not sure the right gate was open?? Oh well, another day.

So I got a coupon for a restaurant at Tacoma Mall so I figured I would go there to charge and eat so I get there and its its usual busy Saturday afternoon with several dozen jockeying for parking so I get to chargers and we have 3 campers; 2 LEAFs and a Volt that is parked blocking a DCFC.

 Luckily there was a space on the other side next to the Gray LEAF so I was able to charge.  Later a Facebooker reported that DC1 (facing pix) was inoperable which I confirmed

The button is stuck which means it will not lock into place when plugged in. Unlike the older AV plugs which could be fooled by holding them in place, these won't work.  I tried to loosen the plug and it simply did not work. Something internally is stuck or broken...

So as I was leaving, I was either delayed or witnessed (while not moving) a half dozen traffic issues caused by people who did not realize that nearly all of the lanes between parking spaces at Tacoma Mall are one way and most do not have enough space for two cars to pass... 

One would think the angle in parking would be enough to determine which way you should go but apparently not.  But then again, signs that say  "Electric Vehicle Charging ONLY"  were ineffective so guessing spending money on One Way signs would be money best spent elsewhere...

Charge Timer

Ever wonder if your car will be charged on those days when you have to leave much earlier than normal? Here is one way to tell.  Now I am guessing the car is using standard 6.6 KW charging to calculate the time and I am only using 5.76 KW  EVSE so... I will say that at 3:30 AM when I did leave the charge was done!

Automatic Emergency Braking

I had thought about how I could test the Automatic Emergency Braking System.  Waaaaay back in the day when I was a die hard Prius fan,  Someone tested the AEB system by putting a bunch of cardboard boxes on the road and driving towards them.  The funeral for the boxes was a few days later... 😏 

Now since I already have missing paint from the from a "hit and run" parking lot incident FIVE days after delivery, I decided not to risk any more paint.  But one thing I did notice is that in any case where the AEB senses that E Pedal is not decelerating fast enough, it will at least give a 3 beep warning.  Now will it do the braking too?  Don't know. Since I don't drink, its hard to get up the courage to test it...

Range Test

Again??  Well, the first time I posted my test, I had someone who claimed LEAF Spy estimated range was not to be trusted. I simply could not let that go so I tried it and found out that...

GOM is what cannot be trusted but this time it has a HUGE  hidden reserve at the bottom.  So naturally I had to update the post!  Read more here

DCFC Charging

As reported earlier, my hoped for advantage over the Bolt concerning DCFC charging was simply not happening. Don't get me wrong. The LEAF still charges faster but nowhere near the HUGE  advantage my 30 kwh LEAF had. 

But I did see a tiny sliver of hope!  The other day during our MUCH warmer than normal weather (Seattle smashed its all time high for the MONTH by 3ΒΊ!)  the charge started its ramp down around 60% which is a significant jump over the 52-55% I had seen so far.  Does this mean back to a 75-80% full speed charge come Summer?... Probably not, but still nice to hope. Hope is good!


Jim, our LEAF Spy developer updated the formula that determines SOH because some were reporting a greater than 100% SOH and that caused my SOH to drop 2½% overnight!  As I had mentioned before, both my ahr and SOH have steadily declined.  Also,  the usual tricks to bolster the numbers are not working.  Drive a lot, cycle deeply, QC frequently, etc.  Nothing is working! 

Now the thought that my driving need is no longer enough to overwhelm the pack like the old days did cross my mind so may have to wait for a 700 mile week to make a real determination but even that is seeming unlikely. 

But I only post this for informational purposes only. The reality is the drop is hardly alarming.  Extrapolated, the rate is just at 3% a year.  Now, Jim has decided to go back to the "regular" method of determining SOH (Don't ask me, I have no idea how he does it)

BUT the drop has not affected my range in anyway whatsoever. I am still EASILY getting 150 miles of range in "real life" driving and yeah, that includes slowdowns for traffic but also includes 70 mph jaunts in the very early morning when traffic is "lighter" 

But the BMS is still not behaving like I want it to.  The other day, I charged from a low state about 10% finishing at 4:00 AM. I know this because that was my planned departure time. Since it was only a 125 mile day, I didn't really care if the charge cycle completed or not, I would have enough 😎

Anyway,  taking off in the morning requires a few trips to the garage to load up and I saw the car still charging at 3:50ish but it was done at 4:06 when I left (I get paid for travel so yeah, the time is not approximate)

Again, LEAF Spy readings confirmed an "overcharge"

So now, I guess I need to define "overcharge"  and despite 30 days of ownership, I still can't do that.  I fear my only option is to charge to full every night for 5 days and average the results or see if any consistency shows up. But the damage that full charging can do especially with a rogue BMS scares me a bit... But...will probably do it since I don't see any real way around it.

BUT,,, its not all doom and gloom.  My Hx is is reputed to be a measure of internal resistance where the higher number means lower resistance which is the characteristic of a healthy pack. So....


FYI; This was Friday. I am now almost to 114%  How high can it go??

Stay tuned!

2018 VERY Casual Range Test; Why LEAF Spy Is Still Vital! **EDITED**

Ok, so I drive a lot.  I hear about others who think they drive a lot but then they faint when they see how much I drive so "again" I got a 15,000 mile annual lease (drove OVER 26,000 miles last year) and my dealer happily complied with my request while crying... BUT

My plan is to change jobs this year.  I  am aiming to find something that has much less driving involved. Not sure where but the reality is I am far from being well paid now so getting something else probably won't be too tough... Hopefully. Besides, I have over 8 years experience at the current job including the last 5½ years so its simply time for a change!

Because nothing is settled, just driving around for the sake of science is not something I can afford to do but Friday, I was left with a great opportunity when I realized that I had enough range to make it home easily so I felt this was a great opportunity to do two tests at once!

Test One;

Range test. I did a full charge Friday morning and then spent 115.5 miles trying to wear out the battery. The battery won.  I was doing a medical clinic run of 10 at 8 different locations.  So a lot of street speeds mixed in with 70 MPH freeway sprints for all but about a 6 mile stretch on the 167 to 512 where it was closer to a 45 mile jog.  There was occasional rain but by and large, mild with only short stints of defrost to clear the windows.   When I said I had enough range to make it home, this was without the help of LEAF Spy since I pulled into the garage with 42 on the GOM.

Naturally, the I-5 slog past the Tacoma Dome was moving at its normal speed...

Any way to get to my 151 mile EPA rated "gotta stop now" situation, I needed to get to 35.5 miles.  So I planned out a route that was roughly 146 miles because I didn't want to cut it too close and then not be near a fast charger.  But the weather was a LOT nicer than I expected. It was clear, Sunny and in less than 10 minutes on the road, seat and steering wheel heaters were off and the windows were cracked. It was THAT warm!

With it being so sunny, I had enough extra range so detoured to get car washed. In my previous blog I mentioned that on day 6 or 7 of ownership, someone hit my car at either the Everett Speedway or the Dash Point (Federal Way) Walgreens parking lot.   Since the parking lot was all ice, I suspect Everett but because of that, I have been hesitant to wash the car because the dirt hid the scratch fairly well...

Less than a mile from the car wash,  Low Battery Warning! I should have had LEAF Spy trip meter set but... oh well.  Notice estimated range on GOM.

Just like clockwork, warning comes on right at 87 GIDs just like the other day.  I now realize that I have waaaay too much range left so despite the warmth, sunshine AND the rolled down windows, I am now using heat and defrost as "Turtle Bait".    Traffic is not agreeing with me but then again  we are approaching the Tacoma Dome and the reality is... all is normal which means slowing to 20 mph.  I now realize that I have to go the full (or nearly) 151 miles...  

Thanks to Defrost!,  VLBW comes on at 4 % (just as I predicted!) Notice  estimated range of 17.1 miles to 1% (now set unlike pix above) that matches estimated GOM range at LBW?  

Very Low Battery Warning

So now, I am racing up and down Pacific Highway in front of the Emerald Queen to get to my 151 miles and finally got tired of it... and stopped at 1%   

FYI; Blinking bar on GOM has been on for like 8 miles now so I should be on "fumes", right? Well, at 3.8 miles per kwh to 1% SOC, I actually had 13 miles left!  I could literally have been driving blind for over 21 miles!

End of range test;

Miles driven;  150.6 
Miles left;  13.3 (estimated but realize I trust LEAF Spy just a TEENY TINY SCOOSH more than the GOM)
Total range Estimated;  163.9

Conclusion; Yeah shoulda driven around more but go back to Paragraph one for an explanation.

Thoughts; Why did Nissan hide so much capacity at the bottom? Is there something they know that no one else knows? The general consensus as I understand it is very low SOC is ok and very high SOC is not.  So why is Nissan allowing a High SOC and doing what they can to prevent us from visiting very low SOCs?


Test Two

As mentioned in my Feb 2018 Driving log, my batt stats have not been consistent. Both my ahr and SOH have steadily declined since day one while my Hx has gone thru the roof.  Full charges have been anywhere from 95.5% to 99.5%!  Below is list of full charges. Keep in mind; my log lists driving from the day before with LEAF Spy readings, the morning of.  For example; 

On 2/22/2018, I drove 183.9 miles and stopped and QC'd twice but the LEAF Spy readings were taken the morning of 2/23/2018 at the start of my day. 

datemilesmiles/kwSOHahrHxmphGIDskwh availSOCnotes
2/22/2018183.93.999.60114.98104.243649738.597.792 QC
2/23/201878.43.699.60114.98104.952749738.597.81no drive 2/24

Now previously, my stats were boosted by doing a lot of QC's, sometimes as much as 5 a day.  But with the longer range, it simply wasn't necessary to stop. I simply didn't see the need when I realized I would be getting home with 40-50 miles of range left.   But now I am seeing what a lot of LEAFers are seeing; a slow steady decline in battery stats.  Now, SOH and Hx do not concern me. They move a LOT but it was over 20,000 miles before my 2016 S30's ahr dropped from the max ONE TIME!

Right now, I am not even sure what the max Ahr is so I decided I am doing nothing but QC's for the next several days to see if I can find out!  So plugged into the Blink at Tahoma Market.  Charged 29 mins finishing at about 60% (interestingly, the car is almost the same now...) 

I then left there going straight to Tacoma Mall to plug into the EVGO and started at 100 amps instead of 120 but it dropped to 80 amps within a minute or so.  Unfortunately,  LEAF Spy lost focus when the car was turned off so graphing is not smooth here. Still ended with a decent charge rate

Heat wasn't as bad as expected.  Sooooo,  after all that; any results?
Sadly, not yet.  This morning, stats were down again;  ahr; 114.86, SOH 99.50%  but Hx continued its amazing upward trend to 109.22% 

I am running LEAF Spy on two phones but both are having issues.  Could be the dongle I am using which was an "original" given to me like 5 years ago or so.  It might need to be updated.  

As you can see on the graph, the blue line is not working. My odometer reading is not updating either although it did move a few miles yesterday for the first time in over a week. Very strange but the 2018 is still very new and I have full faith that Jim the LEAF Spy developer will get it figured out. 

Its only day one of the experiment so we shall see where we are at next weekend. As luck would have it, I have 2 local and one very near job so piling on the mileage this week will be a bit of a challenge. Add to the difficulty that AV is currently still not compatible with the 2018's and Olympia Nissan's QC is down (Again!) so no local watering holes for me!  But EVGO at Tacoma Mall is a mile from my office so I will probably be stopping by there a bit this week so stay tuned!!


I am back!  Ok, test two failed.  I was not able to raise the ahr or SOH. They both continue to drop and worse; LEAF Spyers were reporting greater than 100% SOH (Lucky Dogs!) so the developer reconfigured the formula and I instantly lost 2½ %!

But I also fell into a good test of the range again and this was prompted by a comment below stating that Turtle would have been reached by me shortly afterwards on my test above had I not stopped to charge. 

Well, didn't believe that for a second! So had to find out!

The scenario; Fully charged (not very full actually but close enough!) and drove to Bremerton WA for a ships tour.  Trip home slightly slower with a lot of road at 55 mph but the additional range of the LEAF meant not having to take the Tacoma Narrows Bridge home and paying a $6 toll!

Here is end of day one.  The average MPH is misleading since its based on all on time and we did sit in parking lot in Bremerton eating for about 30 mins before actually getting out of the car.  

Like the previous GOM, we do not get a countdown to one so its important to note the trip mileage, GOM and odometer which I have left up for all screens (unlike Test one above...) 

So here we are at VLBW 25 of 28 miles down the road.  Now part of this is when I hit LBW, I changed from errand running to driving around between charging stations in case Turtle did pop up unexpectedly.   So now we are at 50 GIDs which should be good for about  3-4 GIDs per mile minus say 4-10 on the bottom for buffer or about  12-14 miles.

So above we had VLBW which was clearly at 1788 miles on the odo but then at 1793 miles we get the "_ _ _" on the % meter so this is "VLBW 2" or was the above  "LBW 2?"   Interesting...\

So now we should be on the cusp of walking... right?  Ok, we'll see...

Remember the Legacy LEAF?  It had a power meter that consisted of 9 power circles and 4 regen circles? Double walled circles meant that they were available?  Well, my LEAF has segments; 36 power segments and 18 regen segments.  So like the Legacy LEAF, I figured the disappearing power capabilities would be the best way to go for monitoring my LEAF's progress to Turtledom.  And initially this was true.  Soon, segments started fading...well, at least a few anyway.  

Take note of the fact that we are now 12 miles beyond our normally optimistic GOM prediction  😏

So now I am basically circling a half mile route (farthest I dare go from the plug...)  thinking any minute now, the segments will start dropping like flies. I spent most of the time on the power screen and... WELL THIS IS BORING!!.  Where is that damn Turtle!...  So I picked another route that lessen the regen (I actually added a segment back because of regen!) 

Finally I get this! But also lost 18 segments all at once!  So much for the Turtle doing his polite entrance!

So I plugged in after spending EONs getting to this point because I got the waylaid impression that LEAF Spy was not accurate... 

But it would appear AGAIN, that GOM is BS (on the good side this time...) and LEAF Spy is the one if you really want to know what your range is.  Below its interesting that LEAF Spy shows .6 kwh remaining. I am pretty sure (and since I won't try it) that I did not have a mile plus left to drive.  But my lack of top end balancing makes me think my pack is not all that balanced (which in itself is not a bad thing... well, unless you are trying for 175 miles!)  which might have lended to this.

February 2018 Drive Report

As we all know, I started the month LEAFless so it was gas gas gas... So there are two gassers to report on.

The Corolla rental 158.8 miles    $12.03  7.6 cents per mile

My beater Corolla 726.9 miles  $47.64, also 7.6 cents per mile.

Gasser comments on my monthly driving report will be playing a lesser role here. I plan to dump the Corolla soon. It no longer is cost effective to keep it and the jobs its required for is now VERY few.  For very long commutes, I am generally forced to drive company car but they are not always available. There were several medium long jobs that were simply much easier to do in a gasser due to lack of charging, time constraints, etc.   Again, a lot of those have been mitigated by the longer range of the LEAF.

With a 15,000 mile annual lease, my mileage budget is 1250 miles a month and I am proud to say I was within my budget!!... (Please ignore the fact, I have had LEAF less than ½ of the shortest month of the year...)  going a mere 866.7 miles at a cost of $11.05 or 1.28 cents per mile.  NCTC provided me 98.57 kwh. Without that, my cost would have been 2.33 cents per mile assuming I stayed at tier one rates which at this time of year is probably not likely.  One encouraging stat;  Despite using more heat this very short month than likely ALL of last year, I hit 4.15 miles per kwh from the car. Nice!

Due to the NCTC registration challenges, I will likely be billed for a Blink session and didn't write it down but it will be in the $6 something range. Also did a short stint at a Blink level 2 to verify compatibility as one local LEAFer had issues with a level 2 Blink at the Puyallup Fair Grounds. So if in that area, charge at Bill Korum or Kaiser Permanente. The latter requires a Chargepoint account, is only level 2 but its free! And only a  mile or so up the hill past Hospital. I have 5 clients within walking distance so I park and charge there all the time when the weather is good. They have several plugs and I have NEVER seen them full.   FYI; Kia of Puyallup will be putting in dual format DCFC from Greenlots. $10 an hour so options exist!

Speaking of AV (Aeroenvironment) I called AV to report the compatibility issue with 2018's and rep took my info and said someone would get back to me in 24-72 hours. That was about....7-10 DAYS ago.  I chatted with Nissan CS about the issue and got nowhere. Rep simply said "take it to the dealer" despite my telling him upfront that AV was ONLY DCFC I had issues with... After a circular discussion, the only thing I got out if it was "Its an AV problem"...


Well, after all this time, I am surprised that I don't really know what my full battery parameters are.  I am seeing a few trends, namely my ahr and SOH has done a steady decline since day one but my Hx is skyrocketing.


All this is a bit strange but I will have to say that the extra range (and lack of compatibility with AV) has put me in a position where public charging is simply not needed. If its convenient, sure but yesterday I drove 115.5 miles and got home with 40 miles to spare (via GOM and we will get to that later)

On my previous LEAFs what got the numbers up was cooking the pack with multiple QCs, something I have only done once this year. In fact, it was the Blink encounter I paid for a charge on but only because I wanted to verify compatibility.  I was actually working at Walgreens near Dashpoint the next day and their long dead DCFC was working but did not charge because my Blink account was still in limbo.  

There is "some" evidence that multiple QC's might boost the numbers but only GIDs and ahr available went up.  On the one day I QC'd twice, my numbers went up but then I hit the weekend where I didn't use LEAF at all on the 24th and then less than 10 miles the 25th.  

FYI; LEAF Spy lists "real" SOC so the 99.51% seen on the 19th was a bit...."surprising"

I finally saw "Low Battery Warning" for the first time in a week and posted that it came on "at the same time"  @ 8%.  Well, that is about as misleading a statement as you can make!

Before LBW came on at about 16½%  but the GOM on the LEAF said 8%.  I was at 87 GIDs

Today, I will see where VLBW comes on. I am guessing it will be 8% via LEAF Spy but maybe 4% on GOM???  Either way, its looking like the new LEAF has an 8% hidden reserve maybe... maybe. 

I will update when I find out!

2018 LEAF; Week One Ups And (yes) Downs!

Now that I have actually driven the LEAF long enough to make a real evaluation, there is a lot of good things but also some not so good things.  So what do you want first?

Well, studies show that whatever is presented first makes the greatest impact so in order to do this fairly, we shall do the good first! :)

The Good!; E Pedal For Safety

Day One. Snow from Wednesday. It would be what came a few hours later that 
would cause havoc. Notice how innocent it looks here? 

I knew it would be cool but I didn't realize how much of a safety feature E Pedal was until forced to deal with VERY BAD driving conditions.  Now, realize I am in an S so still riding on Ecopias pumped to 44-45 PSI. (was aiming for 43 and missed...)  On a gasser, they are probably one of the worst tires you can use especially on treacherous roads.  But I already knew that regen is THE perfect invention for driving on snow and ice.  Its like driving in low gear all the time without the drawbacks that gassers have with overheating engines, reduced gas mileage, etc.

But the real benefit is E Pedal gave me PERFECT deceleration control.  In most accidents, its driver error that causes it.  Either not paying attention, going too fast or in this past week's case; hitting the brakes too hard on ice.

I-5 about  7 hours before my drive

So anyway, I go beebopping out of the neighborhood at my typical leave time of 3:30 AM and notice that I am the 2nd one out of the neighborhood. Traction was good as it always is in 2-3 inches of fresh snow as long as you are not stopping or turning! Today's drive is  mere 89 miles to Everett... The FAR end of Everett.  Since I charged overnight on Level 2, I thought B mode was best to reduce friction braking but quickly realized that road conditions made it difficult to stop.  So back to E Pedal I went. That was the end of my traction issues!

As I got on I-5, everyone was driving in the right lanes with the far left lane wide open but that lane proved impossible to navigate. The roads had not been plowed so the lane was mostly crisscrossing tracks thru 3 " of snow with ice underneath so back to the right lanes with everyone else. 

As we approached DuPont, I was in the right lane and an SUV in the center lane decided to slow down due to traffic and lost it eventually skidding across the highway in front of me to end up on the shoulder. He was lucky since he didn't hit anything including me.  All I did was let E Pedal slow down enough to miss him and went on.   By now it was 21ΒΊ and I-5 traffic had reduced the road to compacted ice. There was literally no traction at all.  Speeds were dropped to 20-40 mph.  

I exited I-5 at Highway 512 to pick up co-worker and the car in front of me lost it eventually sliding off to the side and hitting the guard rail which caused her to do a 180. She was traveling roughly 25-30 mph. 

You might find this hard to believe but we were 20 mins late. On the Client end; one called in, too scared to drive while another totaled her car about 2 miles from the store.  Needless to say, it was going to be a long day. 

Finally finished and unlike my trip up with a passenger, I was solo going home. So I get on freeway and its clear smooth driving!... for about 5 miles. Then the traffic went back to its normal 20 mph crawl that E Pedal handled with ease. However there was  3 car rear ender right next to me that was so close, for a second they I thought they hit me... but no "bump" so I was good!  What I realized is that despite it now being a balmy 37ΒΊ, there was still black ice on what appeared to be a dry I-5.  Again; E-Pedal simply worked flawlessly. 

 I decided to get off freeway and grab a charge.  My GOM said I had 21 miles of range but I load up LEAF Spy and its says I have 112 GIDs which is nearly double the range!... Oh well, the charge was at AAA in Lynnwood which is one of the quickest ones to hit due to its very close proximity to I-5. 

So, I plug in to EVGO its starts charging and ran 4 minutes and 10 seconds and shut down... Hmmm? Weird. So I restart session and it runs for 25 mins and 37 seconds before I manually turned it off.  Wasn't sure how EVGO would handle this since I only have a free 30 mins but got my 20 kwh!. So its cold but again, I see a drop in the rate just over 50% SOC but it basically went from 120 amps to 100 amps and sat at that rate for a bit so it was not a fast ramp down. Will have to gather more data but looks like it ramps down gradually. 

You can see the little "wedgie" on the Green line when I did the restart.
Notice the Blue line? Neither did I until I realized its at the bottom!

The Irritating; NCTC

Needless to say, as I go South, the roads are somewhat clear compared to Everett which didn't get that much snow to begin with but the temperature is dropping... FAST.   This meant traffic which is slow on a perfect day, is even slower. Black Ice abounds. Accidents aren't as bad as the morning drive but still enough of them.  I soon gave up the hope of getting home in time to do anything so decided a stop at Tahoma Market to test the Blink was a good choice since not stopping meant hitting Ft. Lewis slog at the height of its slowness.   So, I plug in, and it spins and says... "card not recognized" So I try it again, same result.  I called in, and the rep knew me (based on my cellphone number) knew my email addy created specifically for the purpose of this NCTC registration but there was a card issue. I asked if he could fix the card issue. He could not. Well, I was already here and knew that leaving would put me in traffic Hell. I had exited the freeway with average speed of 10 mph and it WILL stay that way until past the Tacoma Dome where it will speed up to normal until Tacoma Mall...about 3 miles away where it would slow down again...

So I said "remote start me" I was hoping he would waive charges but that didn't happen so I stayed plugged in long enough to see a ramp down.  EVGO is known for early ramp downs even on my 2016 LEAF but Blink was generally less prone to early ramp downs in colder weather... But not this time. I turned off car to grab some refreshment at Tahoma Market which accounts for the pause in the graph. Sometimes LEAF Spy runs with car off, sometimes it doesn't. This was on my Samsung Galaxy 4. 

But looks like Nissan has cranked down the fast charge rate so the advantage I was expecting over the Bolt is not going to happen. I am still charging faster than most Bolts I have seen or heard about but the Bolt will probably squeak it out in a long distance race, if it can find a place to charge... 😏

Another 14.93 kwh for $7.31!

So naturally, I get home. Call EZ Charge like Blink rep said I "had" to do.  The system says "if you need help with" and runs off list of vendors, I select Blink and it takes me to Blink rep and it takes me a second to realize this and he tells me the same thing. Have to go to EZ Charge to fix card issue. So I hang up and this time on automated phone system I selected "other" and got EZ Charge rep and explain situation and he says that Blink Rep can fix. I say I talked to 2 Blink reps who can't fix anything. EZ Charge Rep replies "Why am I not surprised"...  

So he says, he can't fix issue with someone else's system but can submit form directly to Blink to fix. He also states that Blink Rep has access to same form... So I give him card #, last 6 of VIN, dealership I got car from and date of adoption for car, etc.  He says it will take "3 to 5" business days.  (It took less than 24 hours) So I guess the question becomes; Should I fight to get my $7.31 back or forget about it which would make gassers feel a tiny bit better since my cost would be higher... 😊

The VERY Good; E Pedal For Performance

When I first got my LEAF, I had some concerns about what role friction braking would have in E-Pedal when the SOC was high. It was a small concern simply because my primary direction leaving my house is uphill so  regen wouldn't play a big role anyway.  But in the name of Science, I still wanted to know if it was an issue.  

Well, there is a lot going against finding out right now. For one; Nissan had issues with cars being damaged due to rogue OBD devices (not a LEAF) so they took steps to prevent that and one of them is to buffer all the data on the bus which means the ability to track real time stats is all but removed.  Now, most of LEAF Spy still works well but the one thing that is now  gone is the "Braking/Motor" graph which would have told me how much if any friction braking was being used. With E Pedal, its not only easy to never touch the brake pedal, its actually normal.  Only in emergency stops would touching the brakes be required at all.  So any hint of braking on the graph would be tell us what we needed to know but alas, the easy way is not available. 

But one thing is VERY clear.  The 2018 LEAF is a HUGE leap in efficiency.  Despite one of the THE worst week ever for driving, I still managed 4.1 kwh on the car.  This included 3 days with extensive heat/defrost use. Unlike my S30, I simply turned it on and left it on which included 2 sessions of 105 mins and one of 65 mins. I won't bother to mention the several shorter sessions.  Even with the unfavorable conditions, the biggest improvement is highway range and its a bit shocking!  With our mostly snow and super cold dry days, the real acid test of rain has not been common but still had a few days and still getting a prelim range estimate in the 140's. I need to add that the extra range has hampered my ability to be a law abiding citizen if you know what I mean... πŸ˜‰

Now that was to be expected somewhat.  The Cd dropped from .32 on the Gen one to .28 on the Gen 1½ and there were other efficiency tweaks but it is a noticeable difference and yeah, E Pedal probably contributed as well!

LEAF Spy logs do verify a healthy dose of regen even at very high SOC. More on this later.

Slow Start; LEAF Spy

The 2018 LEAF has a lot of changes along with their locking down the CANbus so expecting LEAF Spy to have a few hiccups wasn't much of a surprise.  

Notice the charging graphs above? KW line (in blue) isn't working.  Not much of a big deal since the Green line is volts * amps rating which is pretty close. If you saw previous graphs (I have posted many) you will notice both lines follow along the same path.   

When viewing LEAF Spy logs (I think only available on Pro edition?) The OBC power out that used to show charging speed only works on Level 2 with Level 3 not showing anything hence the blue line issue.  Again, the logs are so extensive that you can still tell what the power delivery rate is from the amps being delivered which shows negative on regen or charging and positive when driving. This complicates the situation a bit because before you could see your total kwh gained from regen on a trip. Now both regen and level 3 charging are thrown together. 

But, I have EVERY faith in Jim, the LEAF Spy developer to resolve the issues. The Braking graph screen is gone but the other stuff, I am confident he will get figured out. Even if he doesn't; LEAF Spy is still considered an essential for any LEAFer. 

WTF;  LEAF BMS/Charging

Where to begin! 

Every LEAF I had previously only took a day or two to determine what the new battery pack stats would be. The 2018 has not done this. My stats are all over the map including one day that is VERY concerning.  Realize LEAF Spy log records REAL SOC...

So you tell me. On my 4 full charges, what is the standard I should be using?  On the 506 GID day, I saw E Pedal generating over 8 KW of regen at 99.1% SOC! How can that be good for the battery??

May need to click to expand... not easy to see

I am hoping this is a LEAF Spy glitch (I doubt it though) and not a flaky BMS! One of the things I think contributed heavily to some 30 kwh packs degrading rapidly was a high  Depth of Discharge (DoD) or the amount of the pack that is available for use.   If using the nominal calculation for real pack size we come up with around 41.4 kwh pack.  With 39.3 kwh available, that is 95% DoD which is even higher than the 94.5% DoD the 30 kwh packs had.  I have to think I haven't seen where my pack will settle into.  Now wondering if it will settle into anything at all? 

Someone on reported that a Greenlots charger of unspecified make burned up his charger.  This caught my attention because I have determined that Aeroenvironment DCFCs are not compatible with my LEAF and now this has been verified by another LEAFer in Oregon. 

This is all I get when trying to use AV!

From a LEAFer in Quebec

I got the same issue on the 2018 LEAF SL Demo unit we got from the dealer at Quebec city yesterday,
I tried many times on both blue DCFC charging stations (Flo and ElectricCircuit) but nothing happen.
400V DCFC charging station can't start charging the 2018 LEAF Demo unit.
Definitely an issue. 

Very Bad;  Accident!

For the 2nd time in 2 months, I have been hit!!  My 2016 went over 29,000 miles and I never even got as much as a door ding! It was completely scratch free! But my 2018 didn't even last a full week.  Now with all the slush and dirt on the car, not sure if it happened at Walgreens in Everett or Federal Way but it definitely did happen!!

**WARNING; The following is very graphic and disturbing! Proceed with caution!**

Now I am afraid to wash it because then it will really show up. 
There is paint missing so its probably way worse than it looks! 

Conclusions; (until next week that is) Its All Good!

Ok so this may all seem ominous but in reality its all small stuff.  The BMS issues are likely to be fixed. The rumor is AV just got a 2018 LEAF to test so that should be resolved soon I think but I don't use AV nearly as much as Blink, Chargepoint or EVGO so it doesn't affect me a lot.   Plus with the additional range, I do not plan to charge to full much anyway.  I do it now because its cold and to get the battery parameters but this LEAF has enough range that I simply won't need to go full  most of the time.  I will say I am most impressed by the range I am seeing especially at this time of year!  I fully expect to see 175 come Summer time! It will be glorious!

Now, you might be tired of hearing it, but E Pedal is THE best idea Nissan ever had!  Its ability to drive for you on icy roads is unparalleled!   The reason it works so well is a twofold whammy. EVs naturally will do better on slippery roads simply because they have much greater control of the power to the wheels. Unlike a gasser where you barely touch the pedal, the car will continue to accelerate as it changes gears. Good for tailgating but not so good when trying not to slide into the car in front of you!

EVs don't do that. You barely touch pedal, it goes to a certain speed and sits there. E Pedal takes that super fine control and adds a bit of "cyber steroids" to make you a Pro icer (notice lower caps to differentiate between good "icer" and bad "ICE'r" 😎) where you always have the exact right amount of regen and deceleration! 

So for all you bitching about the weather we had this week. Stop it. I ordered it for the E Pedal test... all in the name of Science!!
