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, andreceives 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, andreceives 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.
