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.

PURPOSE: A heating device of a hybrid vehicle is provided to effectively reduce the heating load of a vehicle by guiding, the air heated by cooling an integrated package module, to the front of the vehicle, and then by supplying it to the air conditioning device of the vehicle. CONSTITUTION: A heating device of a hybrid vehicle comprises a guide duct(12) and a direction control unit. The guidance duct supplies the air heated by the cooling of the integrated package module(11) to the air conditioning device located at the front of the vehicle. According to the manipulation of a heating switch, the direction control unit guides the heated air to the guide duct or the outside. The direction control unit comprises a direction control valve and an electronic control unit. The direction control valve is formed at an exhaust duct directing the air heated through the cooling of the integrated package module to the outside. According to the manipulation of the heating switch, the electronic control unit controls the direction control valve to adjust the flow direction of the air to the guide duct or the outside.
