Abstract
A vehicle battery cooling system that cools a battery built in an electrically powered vehicle includes a water storage tank, a circulating mechanism, a nozzle, a radiating fin, and a processor. The water storage tank is disposed inside the electrically powered vehicle and near the battery, and stores cooling water for cooling the battery. The circulating mechanism causes, when electric power is supplied from an external facility to the battery, the cooling water supplied from the external facility to circulate through the battery and the water storage tank. The nozzle injects the cooling water supplied from the circulating mechanism into a predetermined part of the electrically powered vehicle. The radiating fin is foldable and controls heat transfer between the battery and the water storage tank. The processor controls respective operations of the circulating mechanism and the nozzle, and switching between open and closed states of the radiating fin.
