To provide a high voltage auxiliary machine capable of suppressing drain of a noise for a rapid charge application with a simple structure.SOLUTION: A high voltage auxiliary machine 1 comprises: a main circuit 22; a driving control circuit 23; and an inner switching power source 24. The main circuit 22 switches an electric connection and disconnection of a high voltage battery 6 and a load 21. The driving control circuit 23 controls a driving of the main circuit 22. The inner switching power source 24 converts a power supplied from a low voltage battery 7 or the high voltage battery 6 mounted on an electric vehicle 2 to a voltage for driving the main circuit 22 and the driving control circuit 23 to supply the power to the main circuit 22 and the driving control circuit 23. The high voltage auxiliary machine 1 is structured so that the inner switching power source 24 stops the operation when a vehicle connector 4 electrically connected to the high voltage battery 6 via a power source line 5 is connected with an external connector 10 of a rapid charge application 3.SELECTED DRAWING: Figure 1
【課題】急速充電設備に対するノイズの流出を簡素な構成で抑制することの可能な高電圧補機を提供する。【解決手段】高電圧補機1は、主回路22、駆動制御回路23および内部スイッチング電源24を備える。主回路22は、高電圧バッテリ6と負荷21との電気的な接続および遮断を切り替える。駆動制御回路23は、主回路22の駆動を制御する。内部スイッチング電源24は、電動車両2に搭載される低電圧バッテリ7または高電圧バッテリ6から供給される電力を主回路22および駆動制御回路23が駆動する電圧に変換し、主回路22および駆動制御回路23に電力を供給する。そして、この高電圧補機1は、高電圧バッテリ6に電源ライン5を介して電気的に接続する車両コネクタ4と急速充電設備3の外部コネクタ10とが接続された場合、内部スイッチング電源24が動作を停止するように構成されている。【選択図】図1
