PROBLEM TO BE SOLVED: To provide an energy storage device for a vehicle which can utilize effectively power generated by the vehicle without enlarging the capacity of an in-vehicle battery. SOLUTION: The energy storage device for the vehicle includes a photoelectric converter 12 for converting light into electricity, and an electrothermal converter 11 for mutually converting electricity and heat. The electrothermal converter 11 has an electrothermal converting unit 23 having a function of converting the electricity converted by the photoelectric converter 12 into the heat and a function of converting the heat into the electricity, and a regenerating chamber 21 for performing the thermal storage of the heat converted from the electricity by the electrothermal converting unit 23. The electrothermal converting unit 23 converts the heat stored in the regenerating chamber 21 into the electricity. COPYRIGHT: (C)2005,JPO&NCIPI
