Reliability design of battery management system for power battery

This paper proposes a distributed battery management system (BMS) to meet the reliability design requirements. The proposed BMS consist of two parts that is the main control module and the sampling module. The reliability and electromagnetic compatibility design of these two modules are presented. In addition, the state of health (SOH) estimation of the two modules is analysed. A reliability test platform is developed and the test results show that the proposed BMS has high reliability.
