PURPOSE: A self power generation type vehicle is provided to improve convenience of charging, by charging an external device with electric energy recovered in an energy recovery apparatus. CONSTITUTION: A self power generation type vehicle(100) includes at least one piezoelectric device(102) and an energy accumulation apparatus(104). The piezoelectric device is arranged in a tire of the vehicle. The piezoelectric device generates electric energy by mechanical pressure of the surface of the tire when the vehicle travels. The energy accumulation apparatus is installed in the vehicle. The energy accumulation apparatus charges a battery of the vehicle by accumulating the electric energy produced by the piezoelectric device.
