COOLING AND PREHEATING DEVICE FOR BATTERY PACKS IN ON-LINE ELECTRIC VEHICLE, AND METHOD FOR COOLING AND PREHEATING THE BATTERY PACKS AND POWER GENERATION FROM WASTE HEAT OF THE BATTERY PACKS USING THE SAME

摘要

PURPOSE: A device for cooling and heating a battery pack of a noncontact electromagnetic inductive charging method and a method for generating power by recovering waste heat from the battery pack using the same are provided to improve the efficiency of a system by effectively recovering waste heat from a battery. CONSTITUTION: A battery pack(1) supplies and stores power. A thermoelectric element(2) is installed in the battery pack. The thermoelectric element changes heat generated from the battery pack into electric energy. A DC power supply unit is connected to the thermoelectric element. The DC power supply unit supplies DC power.
