Re: Battery degredation

I found the following HV battery capacity information from Chevrolet Product Information documents for each model year: 2014 Spark EV - 21.0 kWh 2015 Spark EV - 18.4 kWh 2016 Spark EV - 19.0 kWh That's interesting. I had assumed that 2015 and 2016 were the same. Using data from the energy informati...

Re: Battery degredation

I have a 2014 Spark EV 2LT w/o DCFC and it only has 18054 miles on the ODO. The battery capacity, as measured by TorquePro, has dropped from 17.2 kWh to 16.2 kWh over the last 3910 miles. This car is mainly charged using an L1 EVSE set to 12 amps. I also have a 2016 Spark EV 2LT with DCFC and it on...

Re: Weird Behavior

Please be aware that the charging voltage / profile for a 12 volt AGM battery is different than that for a standard 12 volt flooded-cell lead-acid battery. Charging a 12 volt AGM battery with a charger designed for a 12 volt flooded-cell lead-acid battery may eventually damage the AGM battery. I am...

Re: Weird Behavior

After doing some research I concluded that Battery Minder is a better option than Battery Tender (desulfating function + warranty). Note that model 1510 carries a 10yr warranty and better clips than model 1500 (5yr warranty). I originally got the charger for my family 6-seater non-electric Mazda 5,...

Re: Weird Behavior

Not reproducible. If your 12 volt AGM battery is still the original, you may want to replace it or at least give it a full charge. You will need an AGM 12-volt battery charger with the de-sulfating function. I bought one and, during the first week of each month, I make it a point to fully charge the...

Re: Weird Behavior

This happened to my wife today. I wasn't there at the time, and she was unable to reproduce it. I'll see what happens when I go out tomorrow.

Steves Chevrolet Buick in Oakdale has a 25kW charger (Bosch, not the crappy ChargePoint 24 kW unit).

There are two ChargePoint 50 kW (125A) units going in on N Third Ave in Oakdale - work started, unit there, just not turned on yet.
Thanks. This would make Modesto an easy reasonable trip for me.

TorquePro can be used to measure the battery temperature to see if battery cooling is in operation.
I think I'll do that. An OBD2 adapter came in the mail yesterday, but I haven't yet set up Torque Pro or even really looked into it.

Re: Battery degredation

I would love to try a trip to Pinecrest but right now it is not possible. You could maybe do it, but I'm sure that it would be anxiety-inducing. I've been to Pinecrest and back from my home. I should have written it down, but as I recall, I had about 25 miles on the guessometer when I got there, an...
