PROBLEM TO BE SOLVED: To detect an electric leakage part in an electric system with an easy configuration.SOLUTION: An electric leakage part detection system 10 is formed of a vehicle 20 and an external apparatus 30. The vehicle 20 includes: an electric system 22 with a plurality of load apparatuses 24 and a battery 26 supplying electric power to the load apparatuses 24; and an electric leakage sensor 21 detecting the amount of electric leakage of the electric system 22. An external apparatus 30 includes: a drive forcing unit 302 for sequentially driving the load apparatuses 24 with a fixed current when the electric leakage of the electric system 22 was detected; and an electric leakage part specification unit 306 for specifying an electric leakage part based on the result of comparison of the electric leakage amounts when the load apparatuses 24 are driven.SELECTED DRAWING: Figure 1
【課題】電気系統における漏電箇所を簡易な構成で検知する。【解決手段】漏電箇所検知システム10は、車両20と外部機器30とによって構成される。車両20は、複数の負荷機器24および負荷機器24に対して電力を供給するバッテリ26を有する電気系統22と、電気系統22における漏電量を検知する漏電センサ21と、を有する。外部機器30は、電気系統22の漏電が検知された場合、それぞれの負荷機器24を順次一定電流で駆動させる強制駆動部302と、それぞれの負荷機器24を駆動させた際の漏電量の比較結果に基づいて漏電箇所を特定する漏電箇所特定部306と、を有する。【選択図】図1
