An in-vehicle power supply system includes a first power storage device including one or more lithium ion secondary batteries, a second power storage device connected in parallel to the first power storage device, and a charge/discharge control device. The second power storage device includes lithium ion capacitor groups constituted by a first capacitor group including one or more lithium ion capacitors and a second capacitor group connected in parallel to the first capacitor group and including one or more lithium ion capacitors. The charge/discharge control device controls charging/discharging of the first and second power storage devices to supply electric power to a drive source of a vehicle and recovers regenerative energy of the vehicle. When the first capacitor group discharges electric power preferentially over the second capacitor group, the charge/discharge control device performs control such that the second capacitor group is charged preferentially over the first capacitor group.
