<p><P>PROBLEM TO BE SOLVED: To provide a warming device of an on-board battery, the warming device efficiently warming the on-board battery. <P>SOLUTION: Two cooling liquid circuits of a radiator circuit 17 in which cooling liquid for cooling electric equipment (11, 12, 13) of a vehicle excluding the on-board battery 18 is circulated through a radiator 16 and a battery circuit 19 in which the cooling liquid is circulated through the on-board battery 18 are installed. Then, the warming device includes an electric three-way valve 15 which switches over through which circuit of the radiator circuit 17 and the battery circuit 19 the cooling liquid after passing through the electric equipment is circulated, and an electronic control unit 21 which controls the electric three-way valve 15 so as to circulate the cooling liquid through the battery circuit 19 when the cooling liquid temperature is higher than the battery temperature. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
