Management system, management method, control apparatus, and power storage apparatus

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.

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.
