Abstract

A vehicular wireless power feeding system includes a portable apparatus, a vehicle-side wireless power feeding system and a notifier. The portable apparatus operates using power, which is stored in an attached battery. The vehicle-side wireless power feeding system has a wireless power feeder arranged in the vehicle and for wirelessly feeding power to a wireless power receiver of the portable apparatus. The notifier notifies of, as wireless power feeding information, information related to wireless power feeding from the wireless power feeder to the wireless power receiver.

Claims

1. A vehicular wireless power feeding system comprising:

a portable apparatus that includes a battery and operates using power, which is stored in the battery, as operating power;

a vehicle-side wireless power feeding system that is mounted to a vehicle, and includes a wireless power feeder for performing wireless power feeding to a wireless power receiver of the portable apparatus; and

a notifier that notifies of, as wireless power feeding information, information related to the wireless power feeding from the wireless power feeder to the wireless power receiver,

wherein the notifier includes a display unit of the portable apparatus or a display device mounted to a vehicle, and notifies of, as the wireless power feeding information, a position of the wireless power feeder.

2. The vehicular wireless power feeding system according to claim 1,

wherein the notifier notifies of, as the wireless power feeding information, information indicating whether the wireless power feeder enables the wireless power feeding to the wireless power receiver.

3. The vehicular wireless power feeding system according to claim 1,

wherein the notifier notifies of, as the wireless power feeding information, information on electric energy wirelessly fed from the wireless power feeder to the wireless power receiver.

4. The vehicular wireless power feeding system according to claim 1, wherein:

a charging capacity of the battery in the portable apparatus changes when the wireless power feeder performs the wireless power feeding to the wireless power receiver; and

the notifier notifies of, as the wireless power feeding information, information on the charging capacity of the battery that is changed by the wireless power feeding from the wireless power feeder to the wireless power receiver.

5. The vehicular wireless power feeding system according to claim 1,

wherein the notifier notifies of, as the wireless power feeding information, information on whether the wireless power feeding from the wireless power feeder to the wireless power receiver is in a normal state or an abnormal state, when the wireless power feeder performs the wireless power feeding to the wireless power receiver.

6. The vehicular wireless power feeding system according to claim 1,

wherein the notifier is arranged in the vehicle-side wireless power feeding system.

8. The vehicular wireless power feeding system according to claim 1, wherein:
