This reference design provides a 52s Wireless Battery Management Unit (wBMU) for energy storage systems with high cell-voltage accuracy. The wBMU passes voltage and temperature data from each cell to the host controller in real time, using wireless communication technology. The design overcomes challenges in wired battery management system (BMS) architecture by avoiding cumbersome manufacturing processes, reducing frequent maintenance needs, and minimizing failure rates of connectors and harnesses. Wireless communication reduces the number of required cables and connectors, lowering system weight and cost.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
