Have you monitored the voltage for the entire duration of a hour long drive? I have seen the LDO kick out 14v at startup for a little while then it decides at some point to turn off. Usually after 10 minutes or so. Of course it is highly likely that your 18 MY has different parts or firmware...

Posting this here for anyone stumbling on this thread seeing answers: https://www.mykiasoulev.com/threads/12v-battery-in-2016-kia-soul-ev-keeps-dying.1894/#post-13566 That will explain what's going on and what to do to fix the battery not charging during use. TLDR turn on the headlights to...

A year late but here is what's going on and how to fix it: https://www.mykiasoulev.com/threads/12v-battery-in-2016-kia-soul-ev-keeps-dying.1894/#post-13566

In my 2016 Soul Ev, the 12V battery would die all the time. I kept a booster pack with me to deal with it. I have since replaced the battery and the issue has gone away, for now. What I have been able to deduce from monitoring things via OBD2 and torque pro: The LDO regulator that is...

Can you post a screenshot of your Soul EVspy app that shows "Battery SOH Source" is something other than "Calculated from BMS min/max deterioration"? Or just type in what it says, I don't really need a screen shot. If the new 5722 BMS firmware has SOH as a OBD2 PID, that is, calculated by the...

I'll keep posting with new GOM and SOH numbers each time I do a drive cycle. I plan to do one this weekend, so I should have some new numbers on Monday. Jeju, are you saying that the SOH that I read will never report accurately with the new battery and BMS firmware? Is that because Kia changed...

So I took my Soul EV into the dealer today finally, and they were able to install the correct 5722 BMS firmware into the car. Took about 1 hour, and they washed my car too! Now the SOH is 111.5, and the GOM reports 93 miles on a full charge!! I am very happy with that, even though it probably...

Ok, from that table it looks like I have probably have BMS ROM ID 5522 and what I need is BMS ROM ID 5722. This information is covered under Kia TSB ELE 155 (upgrade action 379.PS). Getting this battery replacement has been a nightmare. After 7 weeks with no car, I get my car back with a...

Hello, this seems like the best thread to ask this question: Is the BMS firmware different for the different battery chemistries? My '16 Kia Soul EV recently got a 37510-E4200R battery replacement. I noticed that the SOH still reads 68.4%, same as when I brought it in. I assumed that they...
