Abstract
Official abstract text for this publication.
A charging apparatus for an electric vehicle, the electric vehicle is parked on a power transmission unit provided on the ground, a power receiving unit provided on a lower surface of a vehicle body of the electric vehicle is aligned with the power transmission unit, and the power receiving unit receives electric power energy aerially fed from the power transmission unit to charge a battery mounted on the electric vehicle in a non-contact manner, and the charging apparatus includes a shielding unit for shielding an operation surface of the power receiving unit from outside without hindering power transmission and receiving action. A rolling screen is preferable as the shielding unit.
First claim
Opening claim text (preview).
The invention claimed is: 1. A charging apparatus for an electric vehicle in which the electric vehicle is parked on a power transmission unit provided on the ground, a power receiving unit provided on a lower surface of a vehicle body of the electric vehicle is aligned with the power transmission unit, and the power receiving unit receives electric power energy aerially fed from the power transmission unit to charge a battery mounted on the electric vehicle in a non-contact manner, the charging apparatus comprising: a shielding unit for shielding an operation surface of at least one of the power receiving unit and the power transmission unit from outside without hindering power transmission and receiving action, wherein the shielding unit is a rolling screen provided to cover the operation surface, wherein the rolling screen is made of a material that does not hinder power transmission and receiving action, and always covers the operation surface during charging and during traveling of the electric vehicle, and wherein a portion of the rolling screen covering an entire surface of the operation surface can be changed by the rolling-up mechanism. 2. The charging apparatus for an electric vehicle according to claim 1 , further comprising a sweeping unit for sweeping off dirt adhering to the surface of the rolling screen during rolling-up operations of the rolling screen.
