Safety Management Method for High Voltage Battery

摘要

PURPOSE: A high voltage battery safety controlling method and a high voltage battery cooling structure related the same are provided to improve a safety of vehicles by preventing a generation of a combustible gas due to overcharging state of the high voltage battery loaded on vehicles. CONSTITUTION: An overcharging state of a high voltage battery is determined(S11). A current of all electric apparatuses related to the high voltage battery except for a cooling fan is secluded according to the overcharging state of the high voltage battery(S12). A speed of the cooling fan is controlled. The cooling pan is operated to a maximum speed in case of overcharging state of the high voltage battery in a process of grasping the state of the battery(S13). A duct between the cooling fan and the high voltage battery has a closure structure about the outside.
