Recently, interest in environmental pollution has increased, and in particular, as the air pollution problem caused by automobile exhaust gas has emerged, research and investment in electric vehicles of major global automobile companies have increased. In general, the electric vehicle may be driven using electric energy charged in an internal battery, and the battery may be charged through a charging device. The charging of the electric vehicle is divided into quick charging and slow charging according to the method. In the case of the fast charging method, DC power is supplied to the electric vehicle for a short time through an expensive quick charger equipped with a large capacity converter. ) Power is supplied for a long time. Unlike general vehicle oil, which is mainly supplied to gas stations, electric power, which is the power source of electric vehicles, can be obtained anywhere in the country through the existing electric power grid. Due to the characteristics of ordinary vehicles, which have much more parking time than the charging time, the slow charging method that is charged in the parking lot is expected to be the mainstream.

The repeater 120 or the charging provider cloud server 114 may collect the charging history collected from each charging device 102 in real time, and the collected charging history is used as big data for demand response. Can be. Demand management is a plan or activity in which a power company such as KEPCO, Korea Electric Power Exchange, etc., or a demand management operator such as KT Co., Ltd., and Servone Co., Ltd. reasonably controls and adjusts the use of power on the demand side. It may be activities such as managing the load of (e.g., peak control, increase in the demand of the night, etc.) or improve the efficiency of using the power (e.g., diagnosis of electrical equipment of the customer, providing power saving information, etc.). Repeater 120 (or a separate gateway) or charging provider cloud server 114 may collect the charging history collected from each charging device 102 in real time, through each parking lot, each building, each region It is possible to calculate the charging history for each vehicle, each season or each time zone. As an example, the repeater 120 or the carrier cloud server 114 charges in building B between the daily average total charge of the parking lot A, from 9 am to 12 am, from the charging history collected at each charging device 102. Big data such as the total amount of charges charged, the total number of charges of K electric vehicles in region C over a month, and the building or parking lot with the highest amount of charges during the summer months. That is, it can be used as information for calculating the generation amount standard. In addition, the demand management operator may issue a demand management command based on such big data. The demand management command is a command for adjusting the power usage pattern of the demand side, that is, each charging device 102, for example, a power saving command during a power crisis, for a certain time (for example, from 9 pm to 12 pm). The average power reduction command may correspond to this.

Each charging device 102 may operate in conjunction with a demand management command of a demand management operator. When the demand management operator issues a demand management command, the repeater 120 or the charging provider cloud server 114 performs charging of one or more charging devices 102 in a region, a building, or a parking lot set according to the demand management command for a predetermined time. (For example, from 9 pm to 12 pm) information about the interruption (or reduction) may be passed to each charging device 102 in the area, building, or parking lot, and thus within the area, building, or parking lot. Charging of the one or more charging devices 102 may be stopped for a set time. As an example, when a demand management order for stopping charging of a parking lot belonging to the area A is issued between 9 pm and 12 pm, each charging device 102 in the parking lot belonging to the area A is provided with the demand management command. Accordingly, the charging of the electric vehicle 104 may be stopped between 9 pm and 12 pm. As such, each charging device 102 may operate in conjunction with the demand management command of the demand management service provider, and thus the demand management service provider operates an efficient demand management business without establishing a separate infrastructure for each charging device 102. can do.

In addition, the data storage module 218 may store an event log related to the maintenance of the charging device 102. The event log related to the maintenance of the charging device 102 may include, for example, the time at which the error occurred when the error (or failure) of the charging device 102 occurred, the cause of the error, a part for resolving the error, or It may include information on the replacement history / upgrade history of the algorithm. Each charging device 102 stores an event log related to the maintenance of the charging device 102 in the data storage module 218 when an error occurs or resolution thereof, and stores the event log through the repeater 120 through the charging provider cloud. May be forwarded to server 114. As described above, according to embodiments of the present invention, by recording and storing an event log related to the maintenance of the charging device 102 in each charging device 102, the event log may be used as reference information when an error occurs in the future. Based on this, it is possible to build big data for maintenance of the charging device 102.

In addition, the data storage module 218 may store an upgrade file for remote upgrade of each charging device 102 received through the repeater 120 connected to the charging provider cloud server 114. The upgrade file is, for example, a file for upgrading a function, a service provided by the charging device 102, a part or algorithm applied to the charging device 102, or the like, and the repeater 120 or the charging provider cloud server. Can be downloaded from 114. Each charging device 102 checks whether the repeater 120 (or gateway) or the charging provider cloud server 114 needs an upgrade of the charging device 102 at a set period (for example, once a day). The upgrade file may be downloaded through the repeater 120 and stored in the data storage module 218. In this case, a version related to the aforementioned various functions, services, etc. of each charging device 102 may be remotely upgraded (OTA: Over The Air) through the upgrade file. According to embodiments of the present invention, since a plurality of charging devices 102 are installed for each parking lot, building, or region, a plurality of charging devices 102 may be upgraded by remotely upgrading each charging device 102 using the upgrade file. , Tens of thousands to hundreds of thousands of charging devices 102 can be easily managed.
