<p>PROBLEM TO BE SOLVED: To propose a power supply device for vehicle which can conduct power supply cut-off and power supply return with accurate timing and ease. SOLUTION: This method is provided with a power supply line opening/ closing means 41, which is formed on a power supply line 16 connecting a battery 11 with loads 40A to 40X, electrically conducts the battery 11 with the loads 40A to 40X at the fume of a closed condition, and electrically disconnects the battery 11 from the loads 40A to 40X at the time of an open condition, an engine operation detection means 44 which detects whether or not an engine is in an operative state, an opening/closing control means 43 which sets the power supply line opening/closing means 41 in an open condition by the engine operation detection means 44, when a prescribed period passes after the stopping operation of the engine is detected, and which returns the power supply line opening/closing means 41 set in the open condition to the closed condition by the engine operation detection means 44, when the starting operation of the engine is detected.</p> |
