BMS
The BMS is widely applied in low voltage home ESS in China, Europe and Australia etc.
The high performance of BMS is guaranteed by adopting Automotive-level chips and
self-developed sophisticated BMS software. .At the same time, it’s able to communicate
with mainstream ESS inverters.
BMS Function
- Measuring and Collecting of battery data such as Voltage, Current and Temperatures
- SoC and SoH calculation
- Protection and Warning
- Communication
- Balancing
- The BMS will automatically even-out any difference in the State of Charge between cells
- Key Data recording and storage
- Parallel connection
