Abstract: To achieve improvement in a vehicle battery cooling device in its effect on the cooling of a battery, and also in its mountability in a vehicle through simplification of a passage structure for the cooling. A structure is such that: an upstream end portion of an air inlet passage for cooling down a battery is opened behind and above a rear seat while an upstream end portion of an air inlet passage for cooling down a charger is opened to a space in front of a lower side of the rear seat; and in a case in which an air conditioning device takes in air from a lower part of a cabin and blows out cool air to an upper part of the cabin, air having cooled down the battery is returned into the cabin through the air inlet passage for cooling down the charger.

Abstract: A safety device for a high-voltage component including a cover that covers at least a part of the high-voltage component, a low-voltage circuit that controls a conduction/shut-off state of an electric circuit for supplying power to the high-voltage component, and a selecting unit that selects the conduction/shut-off state of the low-voltage circuit by an operation accompanying an attachment/removal work of the cover.

Abstract: A cover 1b of a battery pack case has an intake port and an exhaust port 31. With in the battery pack case, battery accommodation sections respectively accommodate battery modules and a junction box accommodation section. A supply flow path and an exhaust flow path are provided at ends of each of the battery accommodation section. A guide is provided between the cover and the battery modules accommodated in the battery accommodation portions. The guide and a lower surface of the cover define a distribution flow path. The air introduced from the intake port flows to the exhaust port through the distribution flow path, supply flow paths, clearances between battery cells, exhaust flow paths, and exhaust port. The battery cells are efficiently cooled.

Abstract: The present invention is intended to reduce impact of external forces on a power supply apparatus by placing the power supply apparatus close to a peripheral component inside a vehicle and as far away as possible from ends of the vehicle, which are susceptible to the impact of the external forces from outside the vehicle.
