PROBLEM TO BE SOLVED: To reliably suppress, in a power supply system for a vehicle comprising a first power storage device storing power for running and a second power storage device storing power for auxiliary equipment, depletion of power of the second power storage device.SOLUTION: A DC/DC converter 31 is provided between a main power storage device MB and an auxiliary battery AB. A control apparatus 50 executes extract-charging control for charging the auxiliary battery AB by the DC/DC converter 31 during parking of a vehicle 100. The control apparatus 50 estimates a SOC decreasing amount of the main power storage device MB in a period from when parking time exceeds a predetermined time to when the vehicle 100 is started, and sets an extract-lower-limit SOC based on the estimated SOC decreasing amount. When a SOC is lower than the extract-lower-limit SOC, the control apparatus 50 does not execute the extract-charging control. |
