Problems solved by technology

However, if it is not the case that the person who started the non-contact power transmission or the person who can control the non-contact power transmission is not present, there is no way for other people (third parties) to easily remove the obstacle without being affected by the magnetic field.

Abstract

The invention provides a non-contact charging system enabling a third party as well as a specific person to take a precautionary measure against magnetic field exposure and then to remove an obstaclebetween a power transmission unit and a power receiving unit. The non-contact charging system includes: a power receiving unit mounted on a transportation device; a power transmission unit, installedon a flat surface, configured to transmit power to the power receiving unit in a non-contact manner; and a power supply unit configured to control power supply to the power transmission unit, the power supply unit including an operation portion configured to temporarily stop or resume non-contact power transmission from the power transmission unit to the power receiving unit.

Description

technical field [0001] The present invention relates to a non-contact charging system utilizing a non-contact power transmission technology. Background technique [0002] Patent Document 1 describes a power supply system that quickly detects an obstacle such as a person or an object between a power transmitting unit and a power receiving unit in a system that supplies electric power in a non-contact manner. And control the power supply status. In this power supply system, when the transmission efficiency detected by the transmission efficiency detection unit is lower than a predetermined value, there may be an obstacle, so power transmission is temporarily stopped, and the efficiency is detected by periodically transmitting power with a small amount of power. Then, when the transmission efficiency becomes equal to or greater than a predetermined value, power transmission is restarted with normal power.
