The battery management system (BMS) monitors the battery and possible fault conditions, preventing the battery from situations in which it can degrade, fade in capacity, or even potentially harm the user or surrounding environment.
The MCU and multi-cell Li-ion battery management devices monitor cell voltage, pack temperature, and current, detect faults, and control cell balancing. System Benefits: Delivers superior BMS accuracy with 2mV precision and six sigma long-term drift (LTD), enhancing driving range and battery life.
