The BOS-A BMU (Battery Management Unit) is the central control unit for the BOS-A 7.68kWh high-voltage battery system. It acts as the “brain” of the entire battery bank, managing communication, safety, and performance across multiple BOS-A battery modules.
In a high-voltage setup, while each battery module has its own internal BMS, the BMU coordinates all modules together, ensuring they operate as a single synchronized energy storage system.
