S32K358 Battery Management Unit (BMU) for High-Voltage Battery Energy Storage

RD-BESSK358BMU Active

Roll over image to zoom in

The BMU - RD-BESSK358BMU is a battery management unit (BMU) as part of the 1500VBESS reference design or a stand-alone board for development of custom designs. It is ideal for rapid prototyping of a high-voltage battery management system (HVBMS) hardware and software.

This board provides multiple interfaces (Ethernet, CAN FD, RS485) to communicate with an energy management system in containerized or modular storage in domestic or commercial and industrial use.

For isolated serial communication with battery modules, the board is equipped with a battery management communication gateway and transceiver electrical transport protocol link (ETPL).

This board contains all the control and interfaces for interlock monitoring, contactor control and cyber security.
