Re: 4% SOH drop in six weeks on new car

Mon Nov 13, 2017 6:26 pm

Thanks folks. Sorry I did not have enough info. I live in central NC and use the vehicle for a daily commute of about 20 miles, most of which is on the interstate. I use 15 to 20% of the battery capacity on my commute. I have a level 2 charger at work that I mostly use. I try to let it get to 25 to 40% before I plug it in. Usually charge it to about 90%. I have used a quick charger once.

Not sure about the history of the car before I got it in late August. Bought it from the dealer in Durham. They said it had been at a dealer in Virginia. Leaf spy showed it had been quick charged six times before I got it. It was manufactured in March of this year.

And at 3000 miles the SOH is now at 92%.

Thanks for your help.

Ahh, workplace charging. this explains it all.

Is the car shaded when you are charging?

Do you have daily access to the charger?


@ 20% one way or say 50% daily, why are you charging to 90% especially during the day?

Your SOH is probably accurate. We are headed into Winter so the impact of your daytime charging will be minimized but I would not charge to more than 65-75% during the Summer.

I would charge to full when the day time high temps gets into the 50's. This will help the health of your pack by balancing cells better. plus you will use more battery during Winter.

You REALLY need to get home charging and charge at night during the coolest part of the day during Summer.

Thanks.

Car is shaded at work. Really like charging at work since the charger is supplied by solar panels.

I've done nearly 70k between 2 Leafs...a 2013 and a 2017. Don't sweat it. Also, know that you can "extend" you battery warranty by 5k miles to 105k miles by simply fitting larger tires on your car! I ran some 215/60/16's on my car before I sold it. Fixes the speedo error and makes it spot on. PM me for more info if needed. I ran mine with spacers so not sure if they clear at full steering lock without spacers. I'm looking to do this change on my 2017 soon. But, may just end up with yet another set of aftermarket wheels/tires.

In Winter, you should be good to charge as much as you want. Guessing normal Winter highs is like 40's to low 60's?

In Summer, don't charge over 70% SOC. The lower the better. LEAF packs seem to not tolerate "warmth" very well. Because you have work place charging, I would keep your SOC no higher than 70% or so. As far as what SOC is good or bad? Don't have nothing to give other than the lower the better.

So keep enough in the battery to cover your needs with a buffer and avoid putting in more than you need right away simply because work charging is free... or cheap.
