Description

  The present invention relates to a vehicle power supply device that supplies power to a vehicle that can receive power supply.

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.
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.
FIG. 8 shows the concept of the non-contact power feeding system.
FIG. 8 is disclosed in US Pat. No. 8,035,255.
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 addition, when an electric vehicle enters a building with a built-in parking lot or the like, there is a concern that the battery becomes empty during traveling on the traveling path and the traveling becomes impossible.
