ElCon charger ZEVA BMS...and a charging "thing"

[DaveTM]

When I installed my Leaf pack using a ZEVA BMS 16v2 I purchased an ElCon TC 1800 W charger.

I set the pack charge to 57V and since day 1, the pack would charge up 57.3V before finally shutting down.

Last night was a different story. The pack was up to 57.5V of charging...and the charger was "trickle" charging at about 2amps. So, instead of waiting to see if my HV relay would trip, I just unplugged the charger.

I put in a request to an outfit in California (they did not sell ZEVA's back in 2018 ) and ask if they had any idea what the issue would be.

I'll let ya know. Meanwhile, if you have any thoughts on this I'd appreciate any input.

I was thinking I could reset the max pack charge from 57V to 56V. I do not have the option of setting pack voltages to anything but "round" numbers. In other words I can't set the charger to shutdown at...say 56.8v. I don't have the option of any partial V settings on the charger.
