Abstract

A message specifying any one of a plurality of operation modes is defined between an EMS 200 and a power storage apparatus 140.

Claims

1. A power management system comprising:

a power storage apparatus; and

a power control apparatus which communicates with the power storage apparatus, wherein the power control apparatus,

before setting an operation mode of the power storage apparatus,

transmits a code request to the power storage apparatus, the code request requesting codes applicable for the power storage apparatus, and

receives a code response from the power storage apparatus in response to the code request, the code response including the codes applicable for the power storage apparatus,

after receiving the code response from the power storage apparatus, if the code response includes a code corresponding to an operation mode setup for setting the operation mode of the power storage apparatus, transmits a set message that sets the operation mode of the power storage apparatus,

transmits a request message to the power storage apparatus, if the code response includes a code corresponding to an operation mode request for requesting the operation mode of the power storage apparatus, the request message requesting the operation mode of the power storage apparatus, and

receives a request response message from the power storage apparatus in response to the request message, the request response message indicating the operation mode of the power storage apparatus,

wherein the power control apparatus transmits the code request upon a detection of a predetermined trigger, and wherein the predetermined trigger is a restoration from a power failure.

2. The power management system according to claim 1, wherein the operation mode includes a mode in which the power storage apparatus cooperates with a distributed power source other than the power storage apparatus.

3. The power management system according to claim 2, wherein the distributed power source is a photovoltaic cell apparatus.

4. The power management system according to claim 1, wherein the power control apparatus, after transmitting the set message:

transmits the request message, and

receives the request response message.

5. The power management system according to claim 1, wherein the operation mode includes a mode for charging the power storage apparatus or a mode for discharging the power storage apparatus.

6. The power management system according to claim 1, wherein the power storage apparatus, in addition to the code response, transmits any one of a message indicating a specification of the power storage apparatus and a message indicating a status of the power storage apparatus.

7. A power management method used in a power management system having a power storage apparatus and a power control apparatus which communicates with the power storage apparatus using a predetermined protocol, the power management method comprising, by the power control apparatus:

before setting an operation mode of the power storage apparatus,

transmitting a code request to the power storage apparatus, the code request requesting codes applicable for the power storage apparatus, and

receiving a code response from the power storage apparatus in response to the code request, the code response including the codes applicable for the power storage apparatus,

after receiving the code response from the power storage apparatus, in response to the code response including a code corresponding to an operation mode setup for setting the operation mode of the power storage apparatus, transmitting a set message that sets the operation mode of the power storage apparatus,

transmitting a request message to the power storage apparatus, in response to the code response including a code corresponding to an operation mode request for requesting the operation mode of the power storage apparatus, the request message requesting the operation mode of the power storage apparatus, and

receiving a request response message from the power storage apparatus in response to the request message, the request response message indicating the operation mode of the power storage apparatus,

wherein the power control apparatus transmits the code request upon a detection of a predetermined trigger, and wherein the predetermined trigger is a restoration from a power failure.

8. A power control apparatus which communicates with a power storage apparatus using a predetermined protocol, wherein the power control apparatus comprises a transceiver configured to:

before setting an operation mode of the power storage apparatus,

transmit a code request to the power storage apparatus, the code request requesting codes applicable for the power storage apparatus, and

receive a code response from the power storage apparatus in response to the code request, the code response including the codes applicable for the power storage apparatus;

after receiving the code response from the power storage apparatus, if the code response includes a code corresponding to an operation mode setup for setting the operation mode of the power storage apparatus, transmit a set message that sets the operation mode of the power storage apparatus;

transmit a request message to the power storage apparatus, the request message requesting the operation mode of the power storage apparatus, if the code response includes a code corresponding to an operation mode request for requesting the operation mode of the power storage apparatus; and

receive a request response message from the power storage apparatus in response to the request message, the request response message indicating the operation mode of the power storage apparatus,

wherein the power control apparatus transmits the code request upon a detection of a predetermined trigger, and wherein the predetermined trigger is a restoration from a power failure.

9. A power storage apparatus which communicates with a power control apparatus using a predetermined protocol, wherein the power storage apparatus comprises a transceiver configured to:
