A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack), such as by monitoring its state, calculating secondary data, reporting that data, protecting the battery, controlling its environment, and / or balancing it.
A BMS monitors the state of the battery as represented by various items:
- Voltage: total voltage, or voltages of individual cells
- Temperature: average temperature, or temperatures of individual cells
- State of charge (SOC) or depth of discharge (DOD): to indicate the charge level of the battery
- State of health (SOH): a measurement of the overall condition of the battery
- Current: current in or out of the battery space
We have the ability to design and manufacture high quality PCM and BMS for all types Li-Ion battery packs. Each unit is tested to ensure functional safety and performance.
Frequently Asked Questions
