Abstract

A gateway apparatus includes a managing unit, an assigning unit, a receiving unit, a generating unit and a transmitting unit. The managing unit manages at least one storage battery group including a set of one or more storage battery systems selected from a plurality of storage battery systems. The assigning unit assigns a first storage battery group, which is one of the at least one storage battery group, to a first charge/discharge instruction apparatus. The receiving unit receives an instruction related to charge or discharge from the first charge/discharge instruction apparatus. The generating unit generates a first control order that is a control order for the storage battery systems belonging to the first storage battery group, based on the instruction. The transmitting unit transmits the first control order to the storage battery systems belonging to the first storage battery group.

Claims

1. A gateway apparatus comprising:

a managing unit configured to manage at least one storage battery group including a set of one or more storage battery systems selected from a plurality of storage battery systems;

an assigning unit configured to assign a first storage battery group, which is one of the at least one storage battery group, to a first charge/discharge instruction apparatus;

a receiving unit configured to receive an instruction related to charge or discharge from the first charge/discharge instruction apparatus;

a generating unit configured to generate a first control order that is a control order for the storage battery systems belonging to the first storage battery group, based on the instruction; and

a transmitting unit configured to transmit the first control order to the storage battery systems belonging to the first storage battery group.

2. The gateway apparatus according to claim 1, wherein:

a second storage battery group that is one of the at least one storage battery group does not include a same storage battery system as that of the first storage battery group;

the assigning unit assigns the second storage battery group to a second charge/discharge instruction apparatus;

the receiving unit receives an instruction related to charge or discharge from the second charge/discharge instruction apparatus;

the generating unit generates a second control order that is a control order for the storage battery systems belonging to the second storage battery group, based on the instruction; and

the transmitting unit transmits the second control order to the storage battery systems belonging to the second storage battery group.

3. The gateway apparatus according to claim 1, wherein:

a second storage battery group that is one of the at least one storage battery group includes at least one same storage battery system as that of the first storage battery group;

the assigning unit assigns the second storage battery group to a second charge/discharge instruction apparatus;

the receiving unit receives an instruction related to charge or discharge from the second charge/discharge instruction apparatus;

the generating unit generates a second control order that is a control order for the storage battery systems belonging to the second storage battery group, based on the instruction;

the transmitting unit transmits the second control order to the storage battery systems belonging to the second storage battery group; and

in a case where the instruction from the second charge/discharge instruction apparatus is received when the storage battery system belonging to the first storage battery group processes the first control order, the generating unit rejects an execution of the instruction.

4. The gateway apparatus according to claim 3, wherein the transmitting unit transmits a report that the execution of the instruction is rejected, to the second charge/discharge instruction apparatus.

5. The gateway apparatus according to claim 1, wherein:

in a case where the managing unit receives a report that it is not possible to execute the first control order from one of the storage battery systems belonging to the first storage battery group, the managing unit selects one or more storage battery systems other than the one storage battery system from the first storage battery group, and generates a third storage battery group including a set of the storage battery systems as selected;

the assigning unit assigns the third storage battery group to the first charge/discharge instruction apparatus;

the generating unit generates a third control order that is a control order for the storage battery systems belonging to the third storage battery group; and

the transmitting unit transmits the third control order to the storage battery systems belonging to the third storage battery group.

6. The gateway apparatus according to claim 2, further comprising an information providing unit configured to provide first characteristic information and second characteristic information to each of the first charge/discharge instruction apparatus and the second charge/discharge instruction apparatus, where the first characteristic information indicates an overall characteristic of all storage battery systems belonging to the first storage battery group and the second characteristic information indicates an overall characteristic of all storage battery systems belonging to the second storage battery group,

wherein the assigning unit assigns the first storage battery group to the first charge/discharge instruction apparatus in response to an assignment request of the first storage battery group from the first charge/discharge instruction apparatus and assigns the second storage battery group to the second charge/discharge instruction apparatus in response to an assignment request of the second storage battery group from the second charge/discharge instruction apparatus.

7. The gateway apparatus according to claim 2, wherein:

based on a battery characteristic condition requested by the first charge/discharge instruction apparatus, the managing unit generates the first storage battery group by selecting one or more storage battery systems among the plurality of storage battery systems such that an overall characteristic of all storage battery systems belonging to the first storage battery group satisfies the battery characteristic condition; and

based on a battery characteristic condition requested by the second charge/discharge instruction apparatus, the managing unit generates the second storage battery group by selecting one or more storage battery systems among the plurality of storage battery systems such that an overall characteristic of all storage battery systems belonging to the second storage battery group satisfies the battery characteristic condition.

8. A charge/discharge system comprising:

a plurality of storage battery systems;

a gateway apparatus; and

a first charge/discharge instruction apparatus,

wherein the gateway apparatus comprises;

a managing unit configured to manage at least one storage battery group including a set of one or more storage battery systems selected from the plurality of storage battery systems;

an assigning unit configured to assign a first storage battery group, which is one of the at least one storage battery group, to the first charge/discharge instruction apparatus;

a receiving unit configured to receive an instruction related to charge or discharge from the first charge/discharge instruction apparatus;

a generating unit configured to generate a first control order that is a control order for the storage battery systems belonging to the first storage battery group, based on the instruction; and

a transmitting unit configured to transmit the first control order to the storage battery systems belonging to the first storage battery group.

9. A method comprising:

managing at least one storage battery group including a set of one or more storage battery systems selected from a plurality of storage battery systems;
