1. A charging control system, comprising:
- a distribution device that distributes power;
a plurality of interface devices, each connected to a battery mounted on a vehicle for charging the battery with the power distributed from the distribution device; and
a charging controller that controls charging in said interface device,wherein said charging controller controls charging to said battery by said interface device on a basis of a distribution system connection time when said interface device and said battery are connected to each other and on a basis of a distribution system disconnection time when said interface device and said battery are disconnected in each of said plurality of interface devices,wherein said charging controller controls the charging in compliance with a priority order of said plurality of interface devices so that a target demand amount set in advance is not exceeded, andwherein said charging controller;
calculates an amount of excess or insufficient power needed to charge a battery on a basis of electricity energy that is obtained by adding the electricity energy needed to charge a battery by said interface device, which is performing charging at a present time, to the electricity energy needed to charge a battery by said interface device, which is estimated to be carrying out charging of a battery after an elapse of a predetermined time; and
corrects the target demand amount on a basis of the calculated amount of excess or deficient power.

Abstract
A charging controller (300) controls charging of a battery by an interface device (400-1 to 400-m) on the basis of distribution system connection time when the interface device (400-1 to 400-m) and a battery mounted on EV (500-1 to 500-n) are connected to each other and on the basis of distribution system disconnection time when they are disconnected in each of the interface devices (400-1 to 400-m).

10. A charging controller that controls charging in a plurality of interface devices, each connected to a battery mounted on a vehicle for charging the battery by using distributed power, said charging controller comprising:
-
a control portion that controls charging of said battery by said interface device on a basis of a distribution system connection time when the interface device and said battery are connected to each other and on a basis of a distribution system disconnection time when said interface device and said battery are disconnected in each of said plurality of interface devices, wherein said charging controller controls the charging in compliance with a priority order of said plurality of interface devices so that a target demand amount set in advance is not exceeded, and wherein said charging controller; calculates an amount of excess or insufficient power needed to charge a battery on a basis of electricity energy that is obtained by adding the electricity energy needed to charge a battery by said interface device, which is performing charging at a present time, to the electricity energy needed to charge a battery by said interface device, which is estimated to be carrying out charging of a battery after an elapse of a predetermined time; and corrects the target demand amount on a basis of the calculated amount of excess or deficient power.

11. A charging control method that controls charging in a plurality of interface devices, each connected to a battery mounted on a vehicle for charging the battery by using distributed power, said method comprising:
-
charging said battery by using said plurality of interface devices; and controlling the charging of said battery by said interface devices on a basis of a distribution system connection time when the interface device and said battery are connected to each other and on a basis of a distribution system disconnection time when said interface device and said battery are disconnected in each of said plurality of interface devices; controlling the charging in compliance with a priority order of said plurality of interface devices so that a target demand amount set in advance is not exceeded; calculating an amount of excess or insufficient power needed to charge a battery on a basis of electricity energy that is obtained by adding the electricity energy needed to charge a battery by said interface device, which is performing charging at a present time, to the electricity energy needed to charge a battery by said interface device, which is estimated to be carrying out charging of a battery after an elapse of a predetermined time; and correcting the target demand amount on a basis of the calculated amount of excess or deficient power.
