I try to contact SOK support here, because no answer by e-mail.
it seems i have an issue with the battery (100 amp with self Heating fonction).
This morming my heater installed in my car and wire to the sok battery didn’t work at all. No light on the controler screen! Nothing!
I opened the SOK BMS app, Discharge mode seems ok… but no Electric power available!! Battery Température is 0 deg C, it should work until -20 deg c. Right ?
the low temp charging cut off is activ, but discharge should be available!
I checked the electrical voltage, and is moving from 8 v to 15 v… that is why my car Heather doesn’t work. when the battery temp goes pu, électrical voltage move less and mess, then low temp Charging mode cut OFF switch Off at 5 deg C, and my car Heather works!! what is wrong with that? Anybody can Help me? thank’s for read me, no easy to write for a french git.😉
