WebMay 31, 2024 · A battery management system (BMS) is used to ensure safe and reliable operation of EV battery systems. The normal operation of the BMS highly depends on the installed sensors which provide the BMS the information of current, voltage and temperature for maintaining the battery systems in the safe working condition. WebOct 4, 2024 · Sensor faults in the BMS can have significant negative effects on the system, hence it is important to diagnose these faults in real-time. Existing sensor fault detection and isolation (FDI) methods have not considered battery degradation. Degradation can affect the long-term performance of the battery and cause false fault detection. WebTherefore, an appropriate Battery Management System (BMS) is required to guarantee the proper functioning of such complex devices. Among the different tasks undertaken by a BMS, those most frequently considered in the literature are state estimation, fault diagnosis, safety management and fast charging. crack laptop screen
