I am working on a BMS and I’m stuck at conceptualizing how to design for high current. The design will work with multiple Slave BMS + a Master BMS. The max voltage/current is projected to be 800V/1200 A. Current is increased by adding in parallel. I can get the voltage to the 800V I need, but the current is a bit troubling just thinking how many cells I would have to stack in parallel. I know there is a way to handle such high current:
- I was thinking stack the Cell Mgmt IC in parallel to get the current, then stack stacked Cell Mgmt IC in series to get the voltage.
