Vehicle and power transmission/reception system
Abstract:
A vehicle includes a power reception unit for receiving electric power in a non-contact manner by electromagnetic field resonance, and a device power feeding unit for transmitting electric power to be supplied to an in-vehicle electrical device in a non-contact manner by electromagnetic induction. A distance over which the electric power is transmitted from an external power transmission unit to the power reception unit in a non-contact manner is longer than a distance over which the electric power is transmitted from the device power feeding unit to the in-vehicle electrical device in a non-contact manner. The vehicle further includes a main battery for supplying electric power to a motor generator, and an auxiliary battery. The auxiliary battery has a voltage lower than a voltage of the main battery. The device power feeding unit receives electric power from the auxiliary battery and transmits the power to the in-vehicle electrical device.
