Energy storage device, power management device, mobile terminal and method for operating the same
First Claim
1. A power management device comprising:
- a communication module configured to receive information about solar power generated by a photovoltaic module, information about commercial power supplied to an internal power network, information about load power consumed in the internal power network, and information about an energy storage amount of at least one energy storage device; and
a processor configured to generate a charge command for charging of alternating current (AC) power from the internal power network to the at least one energy storage device or a discharge command for discharging of AC power from the at least one energy storage device to the internal power network based on at least one of the load power information, the commercial power information, the solar power information and the energy storage amount information,wherein the communication module transmits the generated charge command or discharge command to the at least one energy storage device,wherein the processor receives a pairing request signal, through the communication module, from one of the at least one energy storage device, if the one of the at least one energy storage device is powered on,wherein the processor allocates a radio channel for wireless data communication to the one of the at least one energy storage device, and controls the communication module to transmit a pairing response signal to the one of the at least one energy storage device,wherein the pairing response signal includes a radio channel allocation signal, andwherein after pairing is performed, information about an energy storage amount of the one of the at least one energy storage device is received.

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.

10. A method for operating a power management device, the method comprising:
-
receiving a pairing request signal, through a communication module, from one of at least one energy storage device, if the one of the at least one energy storage device is powered on; allocating a radio channel for wireless data communication to the one of the at least one energy storage device; transmitting a pairing response signal to the one of the at least one energy storage device wherein the pairing response signal includes a radio channel allocation signal; receiving information about an energy storage amount of the one of the at least one energy storage device after pairing is performed; receiving information about solar power generated by a photovoltaic module and then supplied to an internal power network; receiving information about load power consumed in the internal power network and information about commercial power supplied to the internal power network; generating a charge command for charging of alternating current (AC) power from the internal power network to at least one energy storage device or a discharge command for discharging of AC power from the energy storage device to the internal power network based on at least one of the load power information, the commercial power information, the solar power information and information about an energy storage amount of the energy storage device; and transmitting the generated charge command or discharge command to the energy storage device. - View Dependent Claims (11, 12)
