I've been having issues with cold weather and installed mini-pad heaters onto pairs of battery (20 BYD batteries / 10 heater pads). The temperature has responded well and is now sitting around 20 degrees. Unfortunately, the Charge Current limit is still limiting things (sitting in the 2-14 degree limit range).
I've even given the BMS controller a heater pad (just in case)...
Any suggestions?
If you have optimised with battery life this also affects cold charge.
Try switching it off. I get the same issue when someone turns the air con down to artic temps in our one install.
Charge derating from the battery side is usually is under 5°C.
The charge current can also be limited due to a cell imbalance. What is the highest/lowest cell voltage?
