    Power Needs of Battery Management System?

    Looks like this balancing goes on for 30 minutes. Mine will do this all night long!

    Power Needs of Battery Management System?

    A year later, I finally have an update. I got proof of substantial current draw from this ChargePoint charging summary. http://imgur.com/a/x38ND In it, you can clearly see the car continue to draw ~.6kW after it reached 100% SOC. I took this to the dealer, but they couldn't reproduce the...

    Power Needs of Battery Management System?

    Just a follow-up. I haven't gotten a chance to talk to any local dealerships about this phantom power draw. I've witnessed it less while I've... 1) kept the battery between 30-80% charged, and 2) started the charge in cooler weather. Not sure which one is more helpful. When/if I talk to a...

    Appreciate it, Norton! I may not have any further updates for a week, but I will follow up on this.

    Power Needs of Battery Management System?

    I spoke with the customer relations center this morning, and they conferred with a technical adviser twice while I was on the line. The technical adviser indicated that a continuous draw of 640 watts in warm weather is normal. They said the car is trying to maintain the battery temperature at 75...

    Power Needs of Battery Management System?

    Yeah, if no one else is seeing this, I guess it's time to speak with some service folks. I'll follow-up here with what I find out. Thanks again!

    Power Needs of Battery Management System?

    I tried the complete disconnect and reconnect first because it was the easiest. :-) It was pretty busy in the first 30 minutes... 2:15p, 300 watts, then fan comes on, down to 120 watts 2:16p, some clicking and whirring, using 200 watts 2:18p, same noises, but watts climb in steps: 515, then...

    Power Needs of Battery Management System?

    Here's more on the continuous energy consumption from my Spark. This is what I've seen after plugging-in my fully-charged car this morning. This represents about 2.8kwh of energy consumption over the course of 4 hours, with none of it going to actually charging the battery. I've overlaid the...

    Power Needs of Battery Management System?

    Really appreciate the discussion guys! So the thinking is that the car pulling 700 watts for a while after charging is normal. And it doesn't do it indefinitely, but just for a little while afterwards...perhaps 30 minutes or so based on Kevin's chart. My 18kwh over-nighter (referenced earlier)...

    Power Needs of Battery Management System?

    MrDRMorgan, thanks for sharing your experience. I'm 100% sure the car had finished charging, yet was still drawing 6 amps / 720 watts of power...at least according to the status light on the dash and the Kill-A-Watt meter. Do you think the inefficiency is because the car is reserving amps for...

    Power Needs of Battery Management System?

    Hi there, this is my first summer with my Spark EV in a hot location -- Sacramento, CA. I've started hearing a fan working in there, even in the cool early morning hours. From reading other forum entries, this would seem like the battery management system keeping the battery cool and healthy...

    Range Anexity seek advice on trip from Oakland to Sacramento

    I've gone the opposite way a few times, Sac to Oakland, and back. I drive the speed limit and have had the AC on. Vacaville is your friend. There are two fast charging stations there, so that increases your chances of getting a quick charge if one of them is down. EVGo charges a...
