Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a power control system capable of distributing power,

The present invention relates to prior art 10-2015-0160729 of the Applicant.

The present invention relates to a power control system that distributes power to control charging and enables power resale.

In particular, the present invention relates to an electric vehicle control apparatus for controlling electric power supply and power distribution through connection between a plurality of connection ports and various power connection apparatuses outside the apparatus, It is possible to resell power by sharing power information through communication.

That is, when the power distribution, remote control, and monitoring functions are disconnected from the charger and connected to the various electrical connection devices, the present invention can remotely monitor and control power from the control center, It is possible to distinguish the building from the building and resell power.

Currently, most of the electric car chargers or power supplies are installed in stand-alone mode, which makes it impossible to communicate with a remote control center. The control center refers to a place where a remote control signal related to electric vehicle charging can be generated.

Therefore, it is impossible to authenticate the user who wants to use the power supply device and to check in real time whether or not there is a failure. Further, for example, there is a problem in that it is impossible to remotely monitor the electric power supply device and the electric vehicle charging operation, and thus can not effectively cope with a power supply situation changing in real time.

These problems soon lead to a disruption in the electric power supply required to charge the electric vehicle, resulting in increased power generation costs and interruption of customer service.

Therefore, it is necessary to monitor the electric power supply situation and charge electric vehicles remotely by adding a remote communication function to the stand-alone electric power supply device which can not communicate with most of the remote communication, and to manage electric power efficiently through this.

In addition, the communication standard between the control center and the power supply device, for example, a communication standard in which all power supply devices installed in various companies can be used as one registered member through member sharing among a plurality of power supply devices, This is a problem that must be solved even for the purpose of sharing membership among the centers.

Also, effective use of idle power remaining in the power supply is a problem to be considered.

Korean Patent Publication No. 10-2011-008807 discloses a related art.

This disclosure discloses a charging station that supplies electric power to an electric vehicle, a charging station that receives electric power from the electric vehicle, a temperature control device that sets an indoor temperature of the building, and weather information of the day, A function of changing the indoor temperature of the building in a peak power consumption time zone by using the reversible electric car information transmitted from the charging station and a function of controlling the electric power to be received from the charging station in reverse, The present invention relates to a power management system including a management device, and has an advantage that a power load of a building can be lowered in a peak power consumption time zone.

However, the disclosed technology has a disadvantage in that it has a limitation in the technology for controlling the operation related to the electric transmission between the electric vehicle and the charging station.

Another related art is Korean Patent Publication No. 10-2013-0066099.

The disclosed technology calculates a charging cost, which is a power cost at the time of charging of a power storage unit where electric power is charged and discharged, and a discharge cost, which is a power cost at the time of discharging, and compares the charging cost and the discharging cost of the power storage unit. If the charging cost is smaller than or equal to the discharge cost, at least one of the renewable power and the grid power is used as the power source. And controls the power conversion section to perform the charge mode in which the power storage section is charged.

However, this disclosure technology compares the discharge cost with the charge cost to determine whether the discharge cost is more expensive, i.e., greater than the cost of raising the profit by reselling the power, and selects charging, discharging or power resale according to the determination result It is not a technique to grasp the power situation at a remote site and determine the resale of the power accordingly.
