Abstract:
A gas temperature controller for vehicular battery comprising:a heat exchanger for removing waste heat from a vehicle engine; a heating loop, being a coolant circulation path, for carrying said waste heat from said heat exchanger to said vehicular battery, which is a high temperature battery, of a vehicle to heat said high temperature battery; a radiator for cooling said high temperature battery; a cooling loop, being a coolant circulation path, for carrying said waste heat from said high temperature battery to said radiator, and connected in parallel with said heating loop so as to have a common flow path with said heating loop; and flow control means having functions for controlling a temperature of a coolant, which is supplied to said high temperature battery through said heating loop, to a constant level by mixing a relatively low-temperature coolant in said cooling in said cooling loop with said coolant in said heating loop.
