Custom BMS for Large LFP Battery Module

Nuvation designed a custom battery management system for a large LiFePO4 (LFP) battery module that resembled a suitcase-sized cordless drill battery. The pure-hardware, microcontroller-free solution simplified development by eliminating software overhead.

Custom BMS
