<P>PROBLEM TO BE SOLVED: To quickly carry out the warming-up (heating) of a large capacity of battery by eliminating fuel consumption for heating the battery without consuming any useless power in an extremely cold region. <P>SOLUTION: This hybrid car is provided with a water-cooled engine 2 and a motor 3 for making a vehicle travel; a battery pack 1 for supplying a power to the motor 3; an engine radiator 4 connected to a water-cooled channel 2a of the water-cooled engine 2 for making coolant liquid circulate with the water-cooled engine 2; and a heat exchanger 6 connected through a bypass valve 5 to the water-cooled channel 2a of the water-cooled engine 2 for warming-up the battery pack 1 with coolant liquid to be made to circulate in the water-cooled engine 2. The hybrid car heats the battery pack 1 by the heat exchanger 6 by making the coolant liquid circulating in the water-cooled channel 2a of the water-cooled engine 2 circulate in the heat exchanger 6 in such a state that the bypass valve 5 is opened. <P>COPYRIGHT: (C)2009,JPO&INPIT |
