Zusammenfassung:	The utility model provides a battery management system which is multifunctional, and is high in universality and convenient to maintain. The battery management system comprises a main board and slave boards, wherein the main board comprises five CAN (controller area network) communication circuits which are connected to a main board micro-control unit; the CAN1 and the CAN2 are respectively connected with a whole vehicle controller and a charger; the CAN3 and the CAN4 are respectively connected with the two groups of slave boards; and the CAN5 is connected with a debugging and remote communicating interface. The main board has an insulating and detecting function, the complexity of the system is reduced, the reliability is improved, and requirements on various applications can be met; the five CAN communication circuits are reserved, the two CAN communication circuits are reserved for an internal network which is communicated with the slave boards while only one CAN communication circuit is reserved for a common BMS (battery management system), requirements on two parallel systems can be met, and requirements on all the existing known applications can be met; and by a wireless transmitting and receiving module, remote procedure upgrading and data acquiring can be realized, system maintenance and monitoring of a power system state are facilitated greatly, and a control algorithm for data analysis is optimized.
