Abstract: A non-contact charging apparatus for a mobile body has a power-receiving device disposed in an electric car, and a power-transmitting device disposed in a manner of non-contact with the power-receiving device. The power-receiving device has a plurality of power-receiving coils distributively arranged in prescribed locations of the car to receive external electric power. The power-transmitting device has a plurality of power-transmitting coils arranged in prescribed locations outside of the electric car corresponding to the plurality of power-receiving coils to transmit electric power. The non-contact charging apparatus for a mobile body transmits electric power in a non-contact manner from the plurality of power-transmitting coils to the plurality of power-receiving coils and charges a secondary battery. Since a plurality of power-receiving coils are provided, electric power can be transmitted efficiently even when there are installation-space or installation-shape constraints.

Abstract translation: 用于移动体的非接触式充电装置具有设置在电动汽车中的电力接收装置和以与电力接收装置不接触的方式设置的电力传输装置。 电力接收装置具有分配布置在轿厢的规定位置的多个受电线圈，以接收外部电力。 电力传输装置具有布置在与多个受电线圈相对应的电动汽车外部的规定位置的多个电力发送线圈，以发送电力。 用于移动体的非接触式充电装置将多个电力发送线圈以非接触的方式将电力发送到多个受电线圈并对二次电池进行充电。 由于设置有多个受电线圈，即使存在安装空间或安装形状的限制，也能够有效地发送电力。
