Abstract: CAN bus is normally used as internal bus in the large-scale Battery Energy Storage System (BESS) at present. FlexRay used as internal bus replacing CAN bus can well meet the requirements of internal communications in the large-scale battery energy storage system. The shortage of CAN bus which is used in the large-scale battery energy storage system and the superiority of FlexRay bus are analysed. Based on the simple introduction of the communication architecture of battery energy storage system,the communication architecture of energy storage battery management system is introduced by focus,and the feasibility of the application and major scheme of the FlexRay communication protocol in large-scale energy storage battery management system are discussed. Network Designer and CANoe. FlexRay are used to simulate the feasibility of FlexRay communication system used in the large-scale battery energy storage system. Simulation results prove that FlexRay bus used in energy storage battery management system can achieve good effects compared with CAN bus.
