Abstract

One embodiment provides a charge/discharge instruction apparatus, including: a charge/discharge instruction unit which instructs a charge/discharge determination apparatus to perform a charge/discharge control of a battery; a charge/discharge information storage unit which stores charge/discharge information for charging/discharging the battery; a control unit which controls an access request to the battery based on the stored charge/discharge information and contents of the charge/discharge control; a generating unit which generates a communication message concerned with the access request controlled by the control unit; and a communication unit which transmits the communication message concerned with the access request to the charge/discharge determination apparatus.

Claims

1. A charge/discharge instruction apparatus, comprising:

a charge/discharge instruction unit which sends an access request to a charge/discharge determination apparatus for performing a charge/discharge control of a battery via the charge/discharge determination apparatus, wherein the access request includes;

operation mode information as to whether a charge/discharge control to be performed on the battery is an on-demand operation or a scheduled operation, and

scheduled power information as to a scheduled power quantity to be required in the charge/discharge control in the case of the scheduled operation, and

wherein the charge/discharge determination apparatus is coupled with the charge/discharge instruction apparatus, another charge/discharge instruction apparatus and the battery receives the access request not only from the charge/discharge instruction apparatus but also from the other charge/discharge instruction apparatus;

a communication unit which transmits a communication message concerned with the access request to the charge/discharge determination apparatus, and which receives a communication message from the charge/discharge determination apparatus; and

a control unit which, when the communication message from the charge/discharge determination apparatus indicates permission to the access request, starts the charge/discharge control of the battery via the charge/discharge determination apparatus, and

which, when the communication message from the charge/discharge determination apparatus indicates rejection to the access request due to permission to the access request from the another charge/discharge instruction apparatus, waits for the communication message indicating permission which is to be sent upon completion of the charge/discharge control with the scheduled operation by the another charge/discharge instruction apparatus based on the scheduled power information, and then starts the charge/discharge control of the battery via the charge/discharge determination apparatus.

2. The charge/discharge instruction apparatus of claim 1, further comprising:

a battery information storage unit which stores battery information concerned with the battery,

wherein the control unit controls the access request based on the charge/discharge information, the battery information and contents of the charge/discharge control.

3. The charge/discharge instruction apparatus of claim 1,

wherein the access request further includes authentication information of the charge/discharge determination apparatus, and

wherein the control unit performs an authentication process between with the charge/discharge determination apparatus.

4. A charge/discharge instruction method, comprising the following steps:

operating a charge/discharge instruction unit to send an access request to a charge/discharge determination apparatus for performing a charge/discharge control of a battery via the charge/discharge determination apparatus, wherein the access request includes;

operation mode information as to whether a charge/discharge control to be performed on the battery is an on-demand operation or a scheduled operation, and

scheduled power information as to a scheduled power quantity to be required in the charge/discharge control in the case of the scheduled operation, and

is coupled with the charge/discharge instruction apparatus, another charge/discharge instruction apparatus and the battery receives the access request not only from the charge/discharge instruction apparatus but also from the other charge/discharge instruction apparatus;

operating a communication unit to transmit a communication message concerned with the access request to the charge/discharge determination apparatus, and which receives a communication message from the charge/discharge determination apparatus; and

operating a control unit to start the charge/discharge control of the battery via the charge/discharge determination apparatus when the communication message from the charge/discharge determination apparatus indicates permission to the access request, and

wait, when the communication message from the charge/discharge determination apparatus indicates rejection to the access request due to permission to the access request from the another charge/discharge instruction apparatus, for the communication message indicating permission which is to be sent upon completion of the charge/discharge control with the scheduled operation by the another charge/discharge instruction apparatus based on the scheduled power information, and then starts the charge/discharge control of the battery via the charge/discharge determination apparatus.

5. A charge/discharge instruction program for causing a computer to execute the steps of claim 4.
