1. A power supply system that supplies power to a load including a specific load, which consumes power temporarily when used by a user, and a load portion, which is other than the specific load and which consumes power constantly at all time periods, the power supply system comprising:
a power storage portion; and a charge-discharge control portion that controls charge and discharge of the power storage portion, wherein, when power is supplied to the specific load,
in a time period during which a current flowing through the specific load, which is part of the load, is equal to or less than a predetermined magnitude, the charge-discharge control portion performs control such that the power storage portion is charged, andin a time period during which the current flowing through the specific load, which is part of the load, is more than the predetermined magnitude, the charge-discharge control portion performs control such that the power storage portion is discharged, the power is supplied to the specific load and to the power storage portion by a power source other than the power storage portion, the specific load is an EV charge portion that charges a battery included in an electric vehicle, the EV charge portion can perform:
a first step in which a current supplied to the battery is made constant, and the battery is charged; anda second step in which, after the first step, the current supplied to the battery is made higher than in the first step and is made constant, and the battery is charged, and when the EV charge portion performs the first step, in at least a part of a time period of the first step, the charge-discharge control portion performs control such that the power storage portion is charged. |
