AI Customer ServiceThermal fault The thermal abnormal in the battery system are called thermal faults, mainly including cooling system faults and abnormal battery temperature. The battery system must operate effectively within a specific temperature range, and high or low temperatures can affect the normal operation of the battery.
Abnormal battery temperature can result in decreased battery performance, shortened lifespan, safety hazards such as fire or explosion, potential system faults, and unstable operation. Remedies include cool-down treatments, system resets, overhaul and maintenance, software updates, and safe energy discharge. 2.3.1. Cooling system fault
Thermal problems in batteries are directly linked to abnormal temperature variations in batteries. Consequently, it is possible to convert the prognosis of battery thermal failure into an issue of forecasting temperature. A precise model can be used to estimate battery temperature in the future.
Voltage and temperature sensor faults may lead to errors in the battery thermal management system or incorrect battery equalization in the BMS. Actuator faults in the BMS include high voltage contactor faults, controller area network (CAN), bus faults, and cooling system faults.
Generally, in some failure scenarios such as short circuit faults, inconsistency faults and connection faults, the battery will generate abnormal heat, and correspondingly the temperature will rise .
Among battery thermal faults, the most common fault is excessive temperature, which can cause significant damage to the battery unit and the entire system. Thermal faults in battery systems, their consequences, and suggested remedies are outlined in Table 4.
