Re: Best way to charge for battery life

For what it is worth:

My 2014 Spark EV [20k miles on the ODO] shows my battery capacity, as measured by TorquePro, is degrading about 1 kWh in 4k miles of driving. This car is charged almost 100% using the 120 VAC L1 EVSE that came with the car. Charging is always set to 12 amps. Today, my full-charge GOM was 92 miles.

My 2016 Spark EV [24k miles on the ODO] shows my battery capacity, as measured by TorquePro, is degrading about 1 kWh in 13.6k miles of driving. This car is charged 80% using a BOSCH L2 EVSE, 240 VAC at 16 amps and 20% at EVGo DCFC stations. Today, my full-charge GOM was also 92 miles.

I have charged my '14 to 100% 5 days a week since I got it in May, '15, with 3500 miles on it.
It finishes around noon and then I move it .25 mi. and it sits until about 5 and I don't plug in overnight, except in the dead of winter.
It's a ~ 50 mile round trip.

It now has +70 k miles and my last data point was 8-29-19.
The 'energy details' page displayed: 81% @ 'energy used' 15.0 kWh - which = 18.52 kWh.
( haven't figured out TorquePro with this car, yet, tho I had it working on my Volt.. :oops: )
I have been seeing 78 - 82 miles on the GOM. (of course this is the best time of year 8-) )
Interstate travel 80% of the commute, occasionally bumping the 90 mph limiter.
I don't know why this is such a great pack !
I definitely don't baby it in any way.
Maybe the cell balancing it does after it charges to 100% is important. :?:
Used '14 2LT w/ DCFC. +71 K miles.
Mostly free charging! Only one LONG visit to the shop....
GM needs Modern Troubleshooting tools for Modern EV's.
3 step Trouble Tree, 2nd guess not covered by warranty and cost $800. 3rd guess fixed the problem.
