PROBLEM TO BE SOLVED: To achieve easy starting of an electric vehicle when an auxiliary equipment battery causes battery exhaustion, without need for major system changes or addition of expensive components.SOLUTION: A start-assist device 10A is configured so that a control circuit 56 executes detection of a connection between a mobile battery 48 and an electric vehicle 12 and detection of battery exhaustion of an auxiliary equipment battery 22. When the control circuit 56 detects battery exhaustion of an auxiliary equipment battery 22, electric power is supplied from the mobile battery 48 to a vehicle control ECU 20 through a first power supply path 38.SELECTED DRAWING: Figure 2
【課題】大幅なシステム変更や高価な部品の追加を伴うことなく、補機用電池がバッテリ上がりを起こしたときに、電動車両を簡単に起動させる。【解決手段】起動補助装置10Aにおいて、制御回路56は、モバイルバッテリ48と電動車両12との接続検知と、補機用電池22のバッテリ上がりの検知とを行う。補機用電池22のバッテリ上がりを制御回路56が検知した場合、モバイルバッテリ48から第1電力供給路38を介して車両制御ECU20に電力が供給される。【選択図】図2
