Patent abstract
A vehicle power supply unit is provided, which includes a part made of degradable plastic, which may be a battery case of a secondary battery, and may be a separator of a fuel cell when the degradable plastic is made conductive. A condition in which the degradable plastic is decomposed is different from a condition in which it is actually used in a vehicle.
