DEYE BOS-B Pro-A3 BMU (Battery Management Unit) is an essential battery-management and communication component designed for the DEYE BOS-B Pro-A3 high-voltage energy-storage platform.

The BMU forms part of the battery management architecture, enabling monitoring, control and communication between the BOS-B Pro-A3 battery system and the connected power-conversion equipment. It is designed to work with the modular BOS-B Pro-A3 battery configuration, which supports 5–16 battery modules in series.

The BOS-B Pro-A3 platform uses CAN communication with the BMS, while the system provides TCP, RS485 and CAN communication interfaces for system integration.
