Claim:
A temperature control device for an on-board battery pack, comprising: an air conditioning unit having an air conditioning functional member which regulates a temperature of air blown into a compartment of a vehicle on which the battery pack is boarded; an air duct through which a portion of the air, of which the temperature is regulated by the air conditioning functional member, is led to the battery pack, the temperature control device for the on-board battery pack regulating a temperature of the battery pack by leading the air to the battery pack through the air duct; a hot water heater receiving at least one of cooling water of an engine for running the vehicle and fluid heated by heat of exhaust gas of the engine as a heat source is disposed on the battery pack; a suction duct is branched from the air duct and is formed to have an exit communicated to an internal air inlet of the air conditioning unit such that air led to the battery pack is suctioned into the air conditioner through the suction duct; and a first change door which is disposed at a branching point, at which the suction duct is branched from the air duct, to selectively communicate the battery pack with (a) the air duct or (b) the suction duct.
