Abstract

The invention provides a temperature controller for a vehicular battery which uses the waste heat of the engine to control the temperature of a high temperature battery, to thereby enable miniaturization of the vehicle and energy savings, and which can accurately control the high temperature battery to an optimum efficiency temperature.

The battery temperature controller comprises: a heat exchanger 11 for removing waste heat from a vehicle engine 3; a heating loop K being a coolant circulation path for conveying heat from the heat exchanger 11 to a vehicle high temperature battery 5; a radiator 9 for cooling the high temperature battery 5; a cooling loop R being a coolant circulation path for carrying heat from the high temperature battery 5 to the radiator 9, and connected in parallel with the heating loop K so as to have a common path C, and a first flow control valve 60 and a second flow control valve 61 respectively provided in the heating loop K and the cooling loop R.
