The BMU is a bridge between the CMUs and the vehicle communication bus. It controls the pre-charge and main contactors of the battery pack as well as collating the telemetry data from the nodes and providing a summary to other components on the vehicle CAN bus. The Orion Battery Management System (BMS) performs three primary functions:
The BMU is a controller designed to be installed in the pack to keep monitoring voltage and temperature of each battery cell for the total lifecycle. The information collected by the HMU and BMU is transmitted to the BCU for safety and energy management.
The BMS of the battery energy storage system focuses on two aspects, one is the data analysis and calculation of the battery, and the other is the balance of the battery.
The single battery management layer is called BMU and has 1 CAN2.0 bus. It is composed of battery acquisition unit BCU and battery equalization unit BEU.
1. Detailed technical solution The battery energy storage system consists of the energy storage battery, the master controller unit (BAMS), the single battery management unit (BMU), and the battery pack end control and management unit (BCMU). 2. Internal communication of energy storage system 2.1 Communication between energy storage BMS and EMS
The BCU is used with the HMU to complete a full function of protection and energy management in at the rack level. The BMU is a controller designed to be installed in the pack to keep monitoring voltage and temperature of each battery cell for the total lifecycle.
