Abstract

A storage battery device is provided with a transmitter which, in cases when a power supply of the storage battery device is turned on, repeatedly transmits, for a prescribed time period, a classification message including the classification of the storage battery device.

First claim

The invention claimed is:

1. An equipment to which a dynamic address is dynamically assigned within a management system having a control apparatus that performs communication with the equipment via a network using the dynamic address assigned to the equipment, wherein the equipment comprises:
a transmitter; and
at least one processor that,
when the equipment is turned on, controls the transmitter to repeatedly transmit a classification message, indicating a class to which the equipment belongs, over the network, for a predetermined time period, using the dynamic address, assigned to the equipment, as a source address, and,
in response to receiving an identification information request message from the control apparatus within the predetermined time period,
cancels transmission of the classification message, and
transmits an identification information message, identifying the equipment, over the network to the control apparatus.

2. The equipment according to claim 1 , wherein the at least one processor controls the transmitter to repeatedly transmit the classification message even after elapse of the predetermined time period, when the identification information request message is not received within the predetermined time period.

3. The equipment according to claim 1 , wherein the predetermined time period comprises a time period needed by the control apparatus to be powered on.

4. The equipment according to claim 1 , further comprising an interface that connects the equipment to the control apparatus in addition to a connection between the equipment and the control apparatus over the network.

5. The equipment according to claim 4 , wherein the at least one processor controls the transmitter to transmit information indicating a status of the equipment via the interface.

6. The equipment according to claim 1 , wherein the network complies with a communication protocol of an ECHONET Lite (registered trademark) system.

7. A management system comprising:
the equipment according to claim 1 , wherein the equipment is a load or a distributed power source arranged in a consumer's facility; and
the control apparatus, wherein the control apparatus is arranged in the consumer's facility, and controls an operation of the load or the distributed power source.

8. The management system according to claim 7 , wherein the control apparatus is powered by power supplied from a grid.

9. The management system according to claim 7 , wherein the equipment is a distributed power source, and the control apparatus is powered by power supplied from the distributed power source.

10. A management method used by an equipment to which a dynamic address is dynamically assigned within a management system having a control apparatus that performs communication with the equipment via a network using the dynamic address assigned to the equipment, the method comprising:
when the equipment is turned on, repeatedly transmitting, from the equipment, a classification message, indicating class to which the equipment belongs, over the network, for a predetermined time period, using the dynamic address, assigned to the equipment, as a source address; and,
in response to receiving an identification information request message from the control apparatus within the predetermined time period, by the equipment,
canceling transmission of the classification message, and
transmitting an identification information message, identifying the equipment, over the network to the control apparatus.
