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

  1. Measuring and Collecting of battery data such as Voltage, Current and Temperatures
  2. SoC and SoH calculation
  3. Protection and Warning
  4. Communication
  5. Balancing
  6. The BMS will automatically even-out any difference in the State of Charge between cells
  7. Key Data recording and storage
  8. Parallel connection
