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 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.

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

wherein the communication unit receives a communication message concerned with access permission to permit the access request,

wherein the generating unit generates an instruction message concerned with the charge/discharge control,

wherein the communication unit transmits the instruction message to the charge/discharge determination apparatus, and

wherein the control unit performs control so that, when the communication unit receives the communication message concerned with the access permission, the generating unit generates the instruction message concerned with the charge/discharge control and the communication unit transmits the instruction message to the charge/discharge determination apparatus.

3. The charge/discharge instruction apparatus of claim 2,

wherein the communication unit receives a communication message concerned with access rejection to reject the access request, and

wherein the control unit performs control so that, when the communication unit receives a communication message concerned with access permission after the communication unit receives the communication message concerned with the access rejection, the generating unit generates the instruction message concerned with the charge/discharge control and the communication unit transmits the instruction message to the charge/discharge determination apparatus.

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

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

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

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

wherein the battery information contains authentication information of the charge/discharge determination apparatus,

wherein the generating unit generates an instruction message concerned with the charge/discharge control,

wherein the communication unit transmits the instruction message to the charge/discharge determination apparatus, and

wherein the control unit performs an authentication process between with the charge/discharge determination apparatus and the charge/discharge instruction apparatus and performs control so that the generating unit generates the instruction message concerned with the charge/discharge control and the communication unit transmits the instruction message to the charge/discharge determination apparatus when the authentication process is completed.

6. A charge/discharge instruction method, comprising:

operating a charge/discharge instruction unit to instruct a charge/discharge determination apparatus to perform a charge/discharge control of a battery;

operating a control unit to control an access request to the battery based on charge/discharge information stored in a charge/discharge information storage unit for charge/discharge and contents of the charge/discharge control;

operating a generating unit to generate a communication message concerned with the access request controlled by the control unit; and

operating a communication unit to transmit the communication message concerned with the access request to the charge/discharge determination apparatus.

7. A non-transitory computer-readable medium storing a charge/discharge instruction program for causing a computer to execute a procedure, the procedure comprising:

operating a charge/discharge instruction unit to instruct a charge/discharge determination apparatus to perform a charge/discharge control of a battery;

operating a control unit to control an access request to the battery based on charge/discharge information stored in a charge/discharge information storage unit for charge/discharge and contents of the charge/discharge control;

operating a generating unit to generate a communication message concerned with the access request controlled by the control unit; and

operating a communication unit to transmit the communication message concerned with the access request to the charge/discharge determination apparatus.
