Product details
Three-level structure of the system
The battery management system (BMS) is divided into three levels of management. It consists of an acquisition unit (BMU), a battery cluster management unit (BCU), and an energy management unit (EMU). It monitors the state of the battery (temperature, voltage, current, charge) status, etc.), a system that provides a communication interface and protection for the battery.
