Re: Newbie w/high mileage 2015 S w/QC

I put our LEAF in the garage in the winter to stay out of the snow, but I'm going to leave her outside in the summer so that any wind around will help cool down the battery while it is charging. For similar reasons I plan to charge in the early morning hours when it is coolest, and the car is driven soon after charging is completed.

My wife would kill me if we had to micro-manage charging every day but I think a good routine that minimizes heat related charging is very worthwhile.

I don't think I'll be able to charge outside in the summer but I may put her on a schedule for early morning charging when it warms up here. I had already done that but took the schedule off after my wife plugged the car in and it didn't charge for when she needed it to have some range on the same day... Lesson learned. It's my understanding that delayed charge tailoring is not quite as easy for me as some have it since my car lacks mobile app access.

Time to train up the wife ;-)

The car has a button that bypasses the charge timer for an immediate charge.
My car also does not have the Nav screen featured timer or smartphone connection but the built-in timer is OK for occasional use.

I have to say, charging my car in Texas heat in the summer in a closed garage would worry me. You should collect some battery temperature data with LeafSpy. I gather that end charge temps in the 70s F are great, up to ~ 85F "ok," and past that the battery is not going to age gracefully if it happens daily. Incidentally, this is also why charging to 100% is best avoided: a lot more heat is sent to the battery during that last 20% of charge. If I recall correctly as much heat is collected the last 20% as the first 80%.

I'm getting a low mileage (24K) 2014 with in-service date 23-MAR-2014. 12-bars and it was at 85% charge. I did LeafSpy Pro on it and found nothing interesting about batteries but the 8mV deviation across all cells. I live in AZ and will commute with this car from Glendale to downtown Phoenix 26 miles each way. I have free charging at home and at the office (company parking lot -chargepoin+).

Questions:

Should I use 115v L1 charge as much as possible, avoid high rates of charging?

Does the 2014 have Lizard battery tech and does that involve cooling the battery during charging?

Do I need to go to a Nissan dealership for an "annual" battery check right away, since I'm buying from RedRockAutoAZ.com which is independent?

Does skipping the annual battery check void the warranty?

I've had 4 hybrid cars since 2003. Are there any significant differences in driving an EV?

Does the 12v battery have a charging system of its' own (charging when connected to AC charge cord) or is it charged from the drive battery?

L-2 charging doesn't heat the pack much either. It's Quick Charging that generates lots of extra heat.

The "Lizard" packs have no active cooling either - just somewhat more heat resistant chemistry. In high heat it isn't extremely effective. There are a few late 2014 cars that may have this pack, but officially the 2014 has the same pack as the later 2013 cars. It isn't a bad pack in normal heat...

Do I need to go to a Nissan dealership for an "annual" battery check right away, since I'm buying from RedRockAutoAZ.com which is independent?


The annual check has to be done by a Nissan dealer. Normally we don't tell people to get them religiously, but since you live in Arizona, you might want to get them...

Does skipping the annual battery check void the warranty?


In theory, but so far not in practice. We don't know of anyone who was denied a replacement pack for that reason alone.

LOTS more low speed torque. You'll wonder how you could stand driving a Prius or Civic hybrid.

It is charged by the car. Earlier leafs, especially 2013 cars, have problems with this, but as of 2014 or 2015 they seem to have largely fixed the problem. Will your car have issues with that? Can't say.

Thanks for your reply LeftieBiker. I charged to 100% last night, after taking delivery from the dealer, as there is no option on my 2014 Leaf S for charging to lesser percentage. Today I drove about 52 miles RT (work and back) and when I plugged in the L1 EVSE at 6:30 PM it told me I needed 14.5 hours to charge back to 100% even though I still had 31 miles on the guess-o-meter. I have to be at work by about 12.5 hours so there was no way... I have ordered a Level 2 EVSE with 3.3 or 3.6 or 3.8 kW (not sure how ALL those are derived from 220-240v and 16A. The one I am getting has the L6-20 plug which will work with my existing garage circuit for the air compressor (240v 1ph 25A). I'll turn off the compressor switch so they can't be on at the same time. I ordered a black powder coated aluminum cord caddy (wall hook) with J1772 holster.

I'll keep the L1 charger in the trunk bag for emergency charging since at the office we have free use of ChargePoint EVSE.

The charge estimate is usually pessimistic, but that's still cutting it close. I believe that you can set your car's single charge timer to finish at 100% shortly before you leave for work. That's all you really need to do to avoid long periods with it sitting at 100%.

Actually, as Leftiebiker said, it's pessimist and you'll probably get back to full, or close to it, certainly enough for the next day's 52 mi RT. However, doing this everyday will cut it too close, especially in the winter.

There are LOTS of options for EVSE's including portable, plug-in, and hardwired. Make sure you get the correct one for your application. The 2015 S + QC package comes with a 6.6 kW charger in the car and can take "UP TO" 30 amps (40 amp circuit) at 240V. However, the car can only accept what the EVSE or the wall can provide. Hence, if plugging into an L6-20 plug, you'll get a maximum of 16 amps, still acceptable and will fill the car in 7 hours. The normal 2015 S without QC package can only accept 3.8 kW or 16 amps, so you're in good company. Just make sure that your EVSE plugs into the wall correctly, or get yourself an electrician (or at least someone who know this stuff)
