Abstract

A recharging system that recharges batteries is provided with a recharging unit that recharges the batteries by consuming power that is supplied. The recharging unit has the ability to recharge the batteries by consuming system power supplied by a power company. The power company sets power rates that are higher the larger the maximum amount of power supplied per unit of time, and a single charge performed by the recharging unit begins in the preceding unit of time among adjacent units of time, and finished in the following unit of time among the adjacent units of time.

Claims

1. In a recharge system for recharging a battery, the recharge system comprises a recharge portion that recharges the battery by consuming supplied power;

the recharge portion is able to recharge the battery by consuming system power supplied from an electric power company;

the electric power company sets a higher power rate as a maximum value of power amount supplied during a unit time duration increases; and

one recharge performed by the recharge portion is started at a time in a front unit time duration of adjacent unit time durations and ended at a time in a rear unit time duration of the adjacent unit time durations.

2. The recharge system according to claim 1, wherein

a time duration required for the one recharge performed by the recharge portion is equal to or shorter than the unit time duration.

3. The recharge system according to claim 1, wherein

a middle time of the time duration for the one recharge performed by the recharge portion is substantially equal to a time at a boundary between the adjacent unit time durations.

4. The recharge system according to claim 1, further comprising a power storage portion that supplies power by means of a discharge;

during the one recharge performed by the recharge portion, the recharge portion consumes both of the system power and the power supplied form the power storage portion.

5. The recharge system according to claim 1, further comprising:

an input portion into which a command from a user is input;

a control portion which controls operation of the recharge portion; and

a notification portion which gives notice to the user;

wherein

when the user inputs, into the input portion, a command for making a reservation for a recharge of the battery, the control portion prepares a recharge schedule of the battery recharge performed by the recharge portion and controls the notification portion to give notice of at least part of the recharge schedule to the user.
