Abstract

An energy storage device, a power management device, a mobile terminal, and a method for operating the same are discussed. The energy storage device includes a battery pack, a communication module to transmit power-on information or energy storage amount information to a power management device and to receive a charge command or discharge command from the power management device, a connector to receive AC power from the internal power network based on the charge command or to output AC power to the internal power network based on the discharge command, and a power converter to, when the charge command is received from the power management device, convert the AC power from the internal power network into DC power based on the charge command, or, when the discharge command is received from the power management device, convert DC power in the battery pack into AC power based on the discharge command.
