A Battery Management System (BMS) prevents overvoltage by monitoring cell voltages, disconnecting loads/chargers via MOSFETs, and balancing cells. It safeguards lithium-ion batteries from damage, thermal runaway, and performance degradation caused by excessive voltage. . Overcharge and overdischarge are common problems in the use of batteries, which not only shorten the battery life, but also may cause safety risks. Reduced performance, decreased lifecycle, and potentially harmful scenarios like thermal. . Most decent battery management systems out there employ balancing, overdischarge protection, overcharge protection, etc. Almost universally they state that the charging voltage is just 4. If the voltage at the power supply output terminals exceeds the OVP setting, the power supply outputs are turned off, thus protecting. . A battery energy storage system (BESS) plays an important role in the management of residential, commercial, industrial, and grid energy storage.
