Description

  The present invention relates to a vehicle power supply apparatus that supplies power to a vehicle that can receive power supply with a non-contact power supply system.

In recent years, electrically driven vehicles have been used.
Therefore, it is necessary to supply power to the vehicle.
For example, power is supplied to a parked vehicle by a power supply device.
The power supply device can supply power to the vehicle in a non-contact manner.

For example, an idea has been studied in which a vehicle has a non-contact power supply secondary coil at the bottom, and the power supply primary coil is installed below the vehicle to supply power to the vehicle.
FIG. 14 is a conceptual diagram of a non-contact power feeding system.
The concept shown in FIG. 14 is disclosed in US Pat. No. 8,035,255.
It is desired to supply power from the primary coil for power supply to the secondary coil for power supply with less energy loss by a non-contact method.
In addition, it is desired that the method of use be easy when supplying power from the primary coil for power supply to the secondary coil for power supply by a non-contact method.

In the non-contact power feeding system, non-contact power feeding is performed from the power feeding primary coil to the power feeding secondary coil through a magnetic circuit formed in a space between the power feeding primary coil and the power feeding secondary coil.
For this reason, there is a reasonable limitation on the distance between the primary coil for power supply and the secondary coil for power supply, and there is a problem that energy loss becomes large when the power supply is used beyond the reduced distance.
