Re: DCFC message 'Charging rate limited to 30% at vehicles request'

My guess would be that the battery pack is "coldgating". If it's a cold morning and batteries are very cold or near freezing, like 32ºF/0ºC - 5ºC region or less, fast charging could irreversibly damage the batteries as the lithium ions would be electroplated permanently, rather than intercalate whic...

Re: DCFC Troubleshooting

Hello, MMONTERO! I also am not familiar with reading the PLC logs but we can give it a try. Have you tried DCFC on any other stations besides this one? What do you mean by "none of the Spark EVs that are here are able to DCFC." Are you saying you've spoken to owners in Costa Rica with DCFC and they ...

Re: MyChevrolet App V5+ Still Broken

Hi Infinion, The link you posted on 10apr2021 now (on 09aug2021) goes to ver 5.4.x and gives the same updated broken app. Earlier you posted a link that still worked for me: https://apkpure.com/mychevrolet/com.gm.chevrolet.nomad.ownership/variant/4.1.0%20%283407%29-XAPK That is rev 4.1 and has all ...

Re: Anyone had a 2014 Chevy Spark lock up?

It's strange because the 1500W Auxiliary Power Module should be providing 14V to the automotive systems continuously while in use. If BustosMan exceeds the ~110A on the 12V DC system and the AGM voltage sags below the voltage needed to keep the contactors energized (or the BCM/ECU calls it quits bef...

Re: Temperature problem?

R39 changed without lower the battery out of the car http://alfa.kachi-snimka.info/images-2021/rgh1633858493m.jpg BUT NO luck - now is cold again and my spark won't start under 15oC (60F) Any other suggestions ? p.s. Is there any chance the car is made only for California hot climate and there is s...

Re: Acceleration with AC on

The Li-ion batteries should be capable of some very high discharge rates, but it's not unlimited. Depending on construction, anywhere from 2C - 30C discharge rate can be expected. For a 14-18kWh battery, 10C would allow 140kW - 180kW discharges depending on SoC. But is it really that cut and dry? If...

Re: Onstar Breaks My Chevrolet App even further...

I systematically went through older xapk versions online and found one that has yet to be blocked by Onstar. Version 4.1 still works and is linked below, this time on APKpure: https://apkpure.com/mychevrolet/com.gm.chevrolet.nomad.ownership/variant/4.1.0%20(3407)-XAPK There are multiple apks in thi...

Re: Onstar may Discount Subscriptions for Spark EV owners

I've let Onstar know that I'd be cancelling app renewal until the issue is fixed. Continuing to pay while downgrading feels more like a fool's errand. At least I'll be able to use what I paid for until the subscription lapses (they certainly didn't offer to credit my account). Yesterday morning I c...

Onstar Breaks My Chevrolet App even further...

I received a call this morning from an Onstar agent. He simply apologized for the long delay (been about a month since I submitted a support ticket and posted here) and wished to inform me that others have posted the same issue (thanks guys!) and that there has been no resolution! The follow-up was ...
