Best battery strategy for low mileage Leaf?

Sun Apr 16, 2017 11:40 am

Hello. I'm new to Leaf ownership, in fact I'm not getting my used red 2015 SV for at least another week. I'm trading from a Hyundai Genesis V8. Quite some change (though I also have a 2006 Prius).

I no longer need the Genesis since I'm now working from home instead of a long distance commute.

The Leaf will be our second car though it will see most use. Our main car is a Ford Flex for when we need to bring our 2 kids and 2 German Shepherd at the same time.

Most days the Leaf will be used to drop and pick up the kids so total daily mileage will be around 12-15 miles with longer trips of 60 mile trips planned for 2-3 times per month.

What is the best strategy for keeping the battery healthy long term?

I'm planning of setting charge to 80% and only charge at night but still charge every night.

Would it be better to set threshold lower?

Would it be better to charge only once or twice per week?

You can't set a 2015 Leaf for 80% charge, I'm afraid. That ended in 2014. You have to just estimate when it will reach that point, and unplug it then.

The best strategy would probably be to charge to about 70% for the short trips, doing it every other day if that works out ok, and then charge to 100% right before the longer trips, letting the pack equalize but not letting it sit long at 100% indicated charge.

Oh! I didn't realize the 2015s stopped the lower charge range option.

So if it always charges full then I will simply let it drain a couple of days then charge it up again.

I appreciate the response.

No problem. It would be best if you timed the 100% charges to finish no more than a few hours before you use the car, especially in Summer. You can dedicate one of the charge timers to this. Then just drive it until you think you need to charge again, to keep it from falling much under 20%.

I've been thinking about this and I've decided to not baby the battery that much after all. It takes away from the fun and easy of use of owning an electric car!

I was going to charge just when I had hit 20% and then only up to 80%. Instead I will use it as the appliance it is. Plug it in all the time and charge it every night. My hope is that Nissan wasn't lying when they decided to remove the 80% charge option. I also hope that their new lizard battery actually keeps capacity a little longer.

So the car will most days go from 100% charge (well really 90+% of true capacity) to about 80% and then get charged up. Several times per month it will go for longer drives with a charge in the middle of the day.

Seem like a pretty easy electric use overall.

You'll still be able to use the car for your current trips for many years like that, but don't complain if it loses 20% capacity over time.

The loss of the 80% option was my biggest pet peeve on my 2015. I always tried to out smart the timer and I still lost 7% a year. It would be so much more enjoyable to own an ev that you can plug in every time you park it and never have to worry about leaving it too full. Nissan really dropped the ball on this.

It existed thru the 2013 model year for US models and was axed for model year 2014.

Not sure about the rest of the world, but 2015 Leafs for Ireland apparently still have the charge to 80% choice: viewtopic.php?p=416013#p416013.

Argh.

Nissan truly doesn't offer a great user experience here. It would be great to always plug-in the car but have it only charge when "range is less then <my preferred minimum range> and then only until range is <my preferred maximum range>" (perhaps adding "oh! and have it charged and ready by 7am and make sure the cabin if comfy by 7.30am").
Perhaps even cooler have the car analyze driving patterns and come up with the pattern itself after a couple of weeks and then keep it adjusting - (Car: "I've noticed that you rarely drive the full range of my battery. You can prolong your battery life if you allow me to set my charge level around your predicted range. Do you want me to do that? - You can easily override charge levels by speaking to me through Alexa").

That way I could always leave it plugged in and not have to worry about keeping track of the stupid battery which would make my daily drive more enjoyable.

Instead I will have to really play with a fixed schedule setting provided if I want to maximize battery life (or only plug-in as needed and keep an eye on the charge and stop it once it reached "enough" range which feels like old-school).
I can probably figure out a schedule for my normal rides where I set a short charge window in the morning that would keep the car battery mostly in the 30-60% range which is still more then I need each day. I still run the risk that any fixed schedule would either keep charging the battery a little more each day or that it wouldn't fully charge the battery back so I end up with not enough range. The schedule would also have to change depending on season which I can't control.

I'm not sure that any other EV manufacturer offer a better interface for charging but then again it seems like at least Tesla doesn't suffer range loss to the same extend Leaf does (I might be wrong).

Any way. Rant mode off but it truly seems like there could be some rethinking around how the charge experience was handled

You can use a ChargePoint web-connected EVSE and a battery maintainer with a hardwired lead in the car that terminates in the charge port. Not fun or easy, but do-able.
