The MOS tube synchronous rectification technology is adopted for the current limiting of multiple battery packs with parallel current greater than 50A, which effectively reduces heat generation, improves efficiency, and reduces area.

The positive electrode topology is adopted to effectively reduce shallow charge and shallow discharge, and prolong battery life; the negative electrode of the circuit has a common ground, which reduces the interference caused by EMC and MOSFET turn-on and turn-off.

In the scenario of battery series and parallel connection and high current, through cell compensation, the mis-opening of the balance caused by the internal resistance pressure difference of the busbar is reduced, and the capacity deviation is reduced. Cell voltage/capacity monitoring is more accurate, effectively extending battery life.

Soft switch: The battery can be set to automatically shut down in standby mode to reduce unnecessary loss; to avoid continuous power consumption caused by forgetting to turn off the lock switch. 

Zero power consumption: cut off the positive power supply load of the battery after shutdown, and the power consumption of the BMS board is as low as 1 microampere.

Hardware secondary protection: cut off the battery load, reduce power consumption, and avoid battery failure caused by battery undervoltage.
