NOVELTY - The temperature control system (100) has a secondary battery (20b) that is arranged separately from a main battery (20a) and electrically stores electric power which is generated by an electric power generation portion (12) and is required for driving of a vehicle. A temperature control portion (21) adjusts a temperature of a vehicle interior using the generated electric power electrically stored by the electrical storage portion. The temperature control portion has a surface (21a) for heating a vehicle interior, and is positioned towards a passenger.    USE - Temperature control system for vehicles such as car.    ADVANTAGE - The adjustment of in-vehicle temperature can be enabled before the boarding which an engine is stopping, without narrowing the space of a vehicle interior. Since the generated electric power electrically stored by the electrical storage portion provided separately from the main battery, the in-vehicle temperature can be adjusted even before a boarding time. Since the temperature control portion positions the surface for heating or cooling toward a passenger, it can flow the temperature-controlled air toward a passenger efficiently. Since the temperature control part is arranged in door lining and/or a center console, it does not narrow the space of a vehicle interior. Since the temperature control portion has a structure which is not directly-contacted to a surface for a passenger to heat or cool by cloth-form segments, it can prevent a burn. The system can produce electric power using the energy of the sunlight and electromagnetic wave which exists and propagates in an external field, without consuming especially the energy for driving of a vehicle.
