Abstract
A discharge device for a vehicle includes a discharging circuit that connects a second capacitor and a discharging resistor in parallel through activation of a forced connection device. When a collision of the vehicle is detected, the discharge device forcibly stops electricity supply from the storage battery to the electric circuit including the second capacitor, and activates the forced connection device to forcibly discharge the second capacitor. A pair of connecting terminals of the forced connection device are arranged to be pressed against each other with an insulating member disposed therebetween. The forced connection device includes a gas generator for generating combustion gas directed to the insulating member. When an abnormality is detected, the forced connection device short-circuits the connecting terminals with each other through activation of the gas generator. The second capacitor and the discharge device are provided integrally.
