A power transmission device provided by an aspect of the present disclosure comprises: a high frequency power device; a power transmission unit; and a power transmission side control part. The high frequency power device generates a high frequency power. The power transmission unit has a power transmission coil, and transmits the high frequency power received from the high frequency power device to a power reception device mounted on an electric vehicle in a non-contact manner. The power transmission device side control part calculates a power transmission device usage rate which is a rate of a time of transmitting the power to the power reception device in terms of unit time. The power transmission from the power transmission unit is stopped when a corresponding power transmission device usage rate exceeds a preset threshold.

    본 개시의 일 측면에 의해서 제공되는 송전장치는, 고주파 전원장치와, 송전유닛과, 송전장치측 제어부를 포함한다. 상기 고주파 전원장치는 고주파 전력을 발생시킨다. 상기 송전유닛은, 송전 코일을 구비하고, 전동차량에 탑재된 수전장치에, 상기 고주파 전원장치로부터 입력되는 고주파 전력을 비접촉으로 송전한다. 상기 송전장치측 제어부는, 상기 단위시간에 대한, 상기 수전장치에 송전하고 있는 시간의 비율인 송전장치 사용률을 산출하고, 해당 송전장치 사용률이 미리 설정된 역치를 초과한 경우에, 상기 송전유닛으로부터의 송전을 정지시킨다.
