The "minimum battery workout per week" topic

Fri Jul 17, 2020 3:02 pm

Hi - I drive a 2017 Nissan Leaf SV that hits the three year mark on August 1, and has 8,801 miles on it as of this writing.

Given that I'm NOW driving almost not at all, AND I BELIEVE I've read from folks like Dave in Olympia (?) that EV batteries need 'workouts' just like us humans do, I'm wondering:

Q: Is there a consensus on the MINIMUM miles I should be driving each week in order to maintain battery health?

Is there also a minimum number of miles I should target for each individual drive?

My typical errand-based journey runs anywhere from 2 to 5 miles, round trip.

Thank you.

No. Never heard of any.

Just recommend not being at high SoC for extended periods of time, esp. in hot weather.

From looking at Leaf Spy, it looks like my Leaf has moved about 200 miles in the last 4 months due to not driving to work (due to lockdown and county health orders, work policy, etc.) and mostly driving my Bolt when I do drive (long story).

My '19 Bolt (bought end of Jan 2019) is only at 9,752 miles right now. From Onstar emails vs. current stats, looks like my Bolt has moved about 1000 miles between end of March and now.

'13 Leaf SV w/QC + LED & premium (lease over)

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

I have several thousand fewer miles on my 2018, and the lack of driving doesn't seem to have harmed the battery. Or helped it.

SOH from LeafSpy or similar tools is the car's estimate of battery state of health.

SOH is an estimate, not a measurement.

The SOH estimate can be increased by various things that clearly or likely don't have any actual benefit to the real state of health of the battery.

The SOH estimate can be lowered by various other things that clearly or likely don't have any actual harm to the real state of health of the battery.

Thanks, Wet, for reminding us, once again, that Life Is Just a Dream. Or maybe a simulation. So, to slightly garble an old radio admonition, "Don't trust that dial!" ;)

Thanks all. So it seems like I can drive as little as 10-12 miles per week for the next year, and this should have no negative impact.

Awesome.

Stupidly expensive on a per mile basis, but awesome.

The issue you are most likely to have is a low 12 volt accessory battery. If you can't top it off with a little battery maintainer or an external charger once a month (I'm about to hardwire mine for that) then try running the car for 1/2 an hour every week or two in Ready mode, with climate control on. You don't have to actually drive it.

Interesting. Thank you, Leftie!

I can drive around for 30 min per week. Climate control? OK, if I have to.

You can just start the car and leave it where it is if you don't want to go on the road.

The Leaf will charge the 12 volt battery with more voltage in climate control mode, or at least that's what some have found here. Driving the car is unnecessary because unlike an internal combustion engine with an alternator, it doesn't need for the "engine" to be spinning to provide power. That comes from the DC-DC converter, which takes high voltage DC from the pack and converts it to roughly 13-14 volts DC (thus the name).
