POWER SOURCE SYSTEM OF VEHICLE, AND VEHICLE EQUIPPED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a power source system of a vehicle, the power source system being able to make a temperature of a battery approach an appropriate value by effectively utilizing exhaust heat without adding a heater or the like, and to provide the vehicle equipped with the same.

SOLUTION: The power source system of the vehicle includes: an auxiliary battery installation part 154 where a backup auxiliary battery 151 can be installed; a DC/DC converter 141 for boosting a voltage of the auxiliary battery 151 to supply it to a main battery 10 in case that the auxiliary battery 151 is installed in the auxiliary battery installation part 154; a battery cooling fan 12 for causing a flow of a coolant for cooling the main battery 10; and a pathway formed between the main battery 10 and the battery cooling fan 12, through which the coolant is passed. The pathway includes: a first pathway where a DC/DC converter 140 is arranged between the main battery 10 and the battery cooling fan 12; and a second pathway where the DC/DC converter 141 is arranged between the main battery 10 and the battery cooling fan 12.
