A temperature control device has a heat exchanger recovering heat from exhaust gas of an engine, a water circulating passage in which a cooling water is circulated while receiving the recovered heat, an air conditioning unit heating air with the hot cooling water of the passage to produce a temperature controlled air, an air duct, a water heater attached to the bottom surface of a battery pack, and an electric heater attached side surfaces of the pack. The conditioning unit blows the controlled air against the battery pack through the duct. The water heater receives the hot cooling water of the passage and raises the temperature of the battery pack. The electric heater subsidiarily warms the battery pack with heat generated from electric power of the pack. |
