The disclosed vehicle power supply management system includes a main contactor (4, 5), a precharging contactor (7), a precharging resistor (8), a capacitor (14, 24), and a control device (30). The control device (30) executes a precharging control and a main control. The precharging control is a control raises a voltage of the capacitor (14, 24) by engaging the precharging contactor (7) in response to a ready request. The main control is a control that, after the voltage of the capacitor (14, 24) reaches a voltage of the battery (2), engages the main contactor (4,5) and disengages the precharging contractor (7). If the ready request vanishes while the precharging control is executed, the control device (30) maintains an engaging state of the precharging contactor (4, 5) until the voltage of the capacitor (14, 24) reaches the voltage of the battery (2).
