Thanks to the fine folks at KTA-EV, I have a new Elithion main board. I still need to add some more EMI shielding (for the faults that occur during regen), but for the most part, it is working well.
Now I need to figure out why the GFCI is tripping when charging. (Hint: probably had to do something with switching the house over to the underground power). Will keep you posted.
While adding EMI shielding to some of the comm wires, I accidentally dropped one of the wires with exposed shielding onto the battery pack. Nice little spark, but now all but 1 of the banks are not reporting. *sigh*
So now I’m talking to the Elithion support person to see what I should do next (other than pull my hair out).
During a test drive I found that I am still getting bank communication faults with the BMS. Specifically banks 3,6, and 7. In order to help solve this, I’ve found some wrap-around EMI insulation in McMaster-Carr. We’ll see if that solves the communication issue.
Well, I was warned, and I forgot. I was reminded again, and lo and behold – there were loose battery posts. 3 of them.
So, I tightened them up, and charged the batteries, and sure enough – the BMS fault during charging is now gone.
Next step is to take Sparky driving and see if the acceleration also causes faults – I sure hope not.
