Charge Cycle won't end

Thu Aug 08, 2019 1:20 pm

Hi all ... brand new owner here of 2016 LT2 ... and a 2017 Volt of 2 years.

When my Spark completes it's charge cycle, it doesn't stop drawing power. It does ramp down the wattage drawn from 3.3kw to about 250w an hour (too much in my mind to be idle). When I unplug it, I finally get the notification from Onstar saying that the charge is complete which could be many hours after it actually completed. On my Volt, I get that notice as soon as it's topped off and it doesn't draw any more power.

Is this normal. If not, has anyone seen this behavior?

Thanks for any input

Not normal.
It is probably the BMS trying to balance the cells.
TMS uses more power than that and you'd hear the fans, circulating pump and AC running, (if it's needs to cool and not heat as it would in the winter).

If it continues, I'd say there is a problem. Give it a few days...

But then,,, good luck convincing the local Chevy 'Techs' that this is a problem..... :(
Used '14 2LT w/ DCFC. +69 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.
