Abstract
An apparatus, system, and method for upgrading firmware of an energy metering device are provided. A method for upgrading firmware of an energy metering device which receives firmware from a server via a network and upgrade firmware includes: transmitting a size of a firmware segment to the server, initializing firmware upgrade, receiving a firmware segment from the server, and controlling the energy metering device to operate with received firmware in response to a request for activating firmware from the server. The server communicates with the energy metering device by using an object model obtained by object-modeling the size of a firmware segment, the firmware segment download, and the activation request.
