DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of an apparatus and method for controlling an energy storage system according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing a control apparatus of an energy storage system according to the present invention, and FIG. 2 is a block diagram showing a control member 150 in a control apparatus of an energy storage system according to the present invention. Here, the energy storage system 100 includes a charging unit such as a plurality of battery packs to supply power to an internal load. The control unit includes an internal charging unit (for example, a small- And / or power input / output by detecting the input / output power and temperature of the battery pack (e.g., a battery pack of medium size and large size).

1 and 2, an energy storage system 100 according to the present invention includes an input unit 110 through which a user's operation signal is output, a charging member 160 having a plurality of charging units 161, A control unit 150 for controlling the charging member 160, a communication unit 130 for connecting and communicating with the terminal, an authorization switch 140 for setting the control member 150 as an administrator mode, And an alarm unit 170 that alerts the user of abnormality as an acoustic and / or luminescent signal.

The charging member 160 includes a plurality of charging units 161 that are charged with power supplied from an external system, and supplies power charged to a load connected to the power failure or the normal operation. The charging unit 161 is charged, for example, by an external system power source converted into a direct current through an AD converter as a battery pack, and converted into AC through a DA inverter to supply power to an internal load. Since the charging member 160 of the energy storage system is generally known in the art, a detailed description thereof will be omitted.

The communication unit 130 includes both a connector to which other terminals are connected and a modem to be connected to the Internet. That is, the energy storage system according to the present invention has a connector and is capable of connecting a terminal connected at the field and a terminal at a remote place via the Internet.

The input unit 110 includes a plurality of keypads in which one or more of symbols, letters, and numbers are combined in the energy storage system 100, such as an ID and a password input by a user and / or an administrator, Value input signal to the control member. Preferably, the input unit 110 and the display 120 are integrated as a touch display.

In addition, since the input unit 110 and the display 120 are provided, in addition to the connection of the terminal by the communication unit 130, it is possible to set the control value output through the display in the field and to view the measurement data. The communication unit can transmit and receive the measurement data file and log information to the connected terminal when the log information recorded in the document creating program and the measurement data file need to be transmitted and received, It is only possible to visually check data when viewing and setting control values.

The control member 150 controls the charging member 160 through a set control value and detects each abnormality and outputs the detected abnormality to the display 120. When the failure occurs, the alarm member 170 is controlled to issue an alarm It is also possible. Here, the control member 150 sets the rights differently for the user and the manager for setting the control value. That is, the control member 150 sets the access right for each ID input through the input unit 110, and selectively grants viewing rights of the data and setting of the control value within the authority range set for the accessor for each ID .

The privilege switch 140 transmits a connection request signal for input / output of all data of the control member 150 and for the highest privilege (for example, administrator mode) capable of setting all the control values. The administrator mode can be connected to the control member 150 as the Internet through the communication unit 130 in addition to the authorization switch 140.

The alarm unit 170 alerts an abnormal state of the energy storage system 100 as an acoustic signal and / or an emission signal under the control of the control member 150. Here, the alarm unit 170 issues an alarm under the control of the control member 150 when the control member 150 is in a set condition (for example, a filling rate or a high temperature).

The control unit 150 includes a user registration unit 151 for registering the authority of the user for each ID, a log recording unit 152 for recording and storing the connection record and use record information of the user for each ID, A program driving unit 153 for driving a document creating program for inputting and outputting, a measuring unit 154 for measuring the filling member 160 under the set conditions, a timer 155 for counting time, A control unit 157 for selectively controlling input and output of data according to access privileges registered for each user registered in the user registering unit 151; Access authority and log information, and a storage unit 158 for storing measurement data of the measurement unit 154. [

The user registration unit 151 stores the ID and password input through the input unit 110, and registers the access right for each ID. The ID and password are registered in the administrator mode. Preferably, the access authority is set to a user mode granted at the user side and an authority range assigned to the administrator.

The user mode is set to have authority to browse the measurement data monitoring the charging unit 161 and the administrator mode is given a setting right such as changing or deleting the control value set in the controller 157, It is preferable that the storage unit 158 is set to have the authority to view all the data stored in the storage unit 158.

The log recorder 152 stores the log-in date and time of the user connected through the communication unit 130 and the input unit 110 and the contents of the operation (for example, data output, file change and deletion). Here, the log recording unit 152 is stored and read out as a document file by the document creation program under the control of the control unit 157 in the administrator mode.

The program drive unit 153 drives a document creation program capable of recording and storing the log information of the log recorder 152 and the measurement data of the measurement unit 154. The program driving unit 153 drives a document creating program that interlocks with the log recording unit 152 and the measurement unit 154 and records log information and measurement data as a document under the control of the controller 157. [

The measurement unit 154 may measure an electrical characteristic such as a voltage and a current that may directly affect the filling rate of the filling member 160 and an environmental characteristic that may affect the safety of the filling unit And humidity in the storage unit 158. The measuring unit 154 measures the filling member 160 according to the conditions set by the controller 157 (for example, the output voltage and the current value per hour and the charging rate and the discharging rate per hour) ). In particular, the measurement unit 154 measures the output voltage and the current value at predetermined time intervals for a predetermined time under the control of the controller 157, and stores the measured output voltage and current value in the storage unit 158.

For example, the measurement unit 154 measures the output current value per second and stores the measured output current value in the storage unit 158. Such a measurement period may provide optimum data for monitoring the performance or abnormality of the charging member 160, but it is necessary to increase the capacity of the storage unit 158 due to a large amount of measured data. Therefore, it is preferable that the measurement of the power versus time as described above is set to measure during the set time in the administrator mode.

The timer 155 applies a counting signal of a predetermined time to the controller 157 under the control of the controller 157.

The shutdown drive unit 156 turns off the energy storage system 100 according to a set upper command when an abnormal signal corresponding to a setting condition under the control of the controller 157 is detected. That is, if an abnormal signal corresponding to the shutdown condition corresponding to the execution condition of the upper instruction is sensed, the shutdown driver 156 executes the command of the higher order, The energy storage system 100 is turned off.

For example, when the charging rate of the charging member 160 is less than 5% through the measurement sensing signal of the measuring unit 154, the shutdown driving unit 156 turns off the energy storage system 100 to prevent the full discharge Or the energy storage system 100 is forcibly turned off when a fire or high temperature is detected as a set high temperature. As described above, according to the present invention, it is possible to shorten the life span of the energy storage system 100 or to issue commands and conditions that can be executed first over an abnormal situation that can cause a large failure, Respectively.

The present invention includes the above-described configuration. Hereinafter, a method of controlling an energy storage system achieved through the above-described configuration will be described with reference to FIGS. 3 to 6.

3 is a flowchart showing a control method of an energy storage system according to the present invention.

Referring to FIG. 3, the control method for an energy storage system according to the present invention includes a rights setting step S100 for setting rights for each ID, a monitoring step S200 for setting a user in the rights setting step S100, The power supply to the load connected to the load connected after or before the setting step S200 of the user and the setting of the manager S300 or the power supply supplied from the external system (S400) of the energy storage system 100 to be charged by the power storage system 100. [

In the right setting step S100, a password for each ID input through the input unit 110 or the communication unit 130 is registered, and rights are set for each ID. In this case, the control unit 157 sets the access right for each of the ID, password, and ID in the administrator mode. That is, when the user ID and password input from the input unit 110 or the communication unit 130 are received, the control unit 157 drives the user registration unit 151 to register a password for each ID. The control unit 157 controls and registers and registers the control value that sets the access right for each ID input through the input unit 110 and / or the communication unit 130 by controlling the user registration unit 151.

At this time, it is preferable that the control unit 157 sets access authority as a user mode and an administrator mode largely according to a command input from the input unit 110 and / or the communication unit 130, and subdivides the authority of the user mode.

The user mode is used to allow a user of the energy storage system 100 to view and monitor measurement data relating to the electrical characteristics (charge rate, output voltage and / or current) of the energy storage system 100 And the administrator mode sets the control value of the energy storage system 100 and the access right of the user.

The monitoring step S200 of the user receives the ID and the password through the input unit 110 and / or the communication unit 130 and compares the ID and the password stored in the storage unit, And outputting measurement data for monitoring the energy storage system. When the ID and the password are applied through the input unit 110, the control unit 157 controls the user registration unit 151 to check the matching ID and password. After confirming the authorization granted to the ID, . This will be described with reference to FIG.

FIG. 4 is a flowchart illustrating a monitoring step of a user's authority in the control method of the energy storage system according to the present invention.

Referring to FIG. 4, the monitoring step S200 of the user may be performed by controlling the power supply to the load and / or the state of the charging member 160 to be charged from the external system in the control member 150 of the energy storage system 100 A login information checking step S220 for checking the login information inputted in the monitoring step S210, a step S220 for checking the login information inputted in the login information checking step S220, A data output step S230 for outputting data according to the authority, and a log information recording step S240 for recording log information including the date and time of log-in and usage information.

The monitoring step S210 is a step of monitoring the process of supplying power to the load in the charging member 160 or charging the charging member 160 with external system power. The measuring unit 154 controls the voltage and current of each of the charging units 161 of the charging member 160 and the voltage and current of each of the battery packs constituting the charging unit 161 under the control of the controller 157 And stores them in the storage unit 158.

If the ID and password are authenticated through the input unit 110 and / or the communication unit 130, the control unit 157 searches for the corresponding ID and confirms the password, . Here, the user (worker) can input his or her ID and password through the input unit 110 and request the measured data in the monitoring step S210. At this time, the controller 157 checks the ID to confirm that the user is an administrator or a user. Therefore, if the user ID is input, the controller 157 controls the display 120 to output the information measured in the monitoring step S210.

The monitoring data output step S230 is a step in which the controller 157 selectively outputs the measurement data of the monitoring step S210 according to the authority of the user connected in the login information checking step S220. The controller 157 outputs the data measured by the measuring unit 154 to the display 120 and selectively provides the data according to the authority granted to the ID.

For example, the measurement unit 154 may measure the output voltage and the current value of each battery pack included in the charging unit 161 in the charging member 160. However, the control unit 157 provides the general user with basic data such as the output voltage and current, and the charging rate as a unit of the charging unit 161 in the charging member 160, And provides measurement data on the electrical characteristics of each battery pack included in the charging unit 161. In addition, it is also possible to grant authority to the advanced user so as to partially change the control value set in the authority setting step S100. This can be set variously according to the application of the user or the designer.

At this time, the controller 157 not only outputs the measurement data through the display 120, but also transmits the measurement data to the program driver 153 through the communication unit 130, . The program drive unit 153 drives the document creation program and stores the measurement data of the measurement unit 154 in the storage unit 158 as a recording and document file.

Therefore, the control unit 157 transmits the measured data from the measuring unit 154 to the display unit 120 through the communication unit 130 as a document file by a commonly known document creating program.

In the log information recording step S240, the control unit 157 controls the log recording unit 152 and the program drive unit 153 to change log information and / or control values of the log record, measurement data, and transmission file , And recording and storing log information of a user such as an operator's ID.

The log information can be used as a data for tracking the cause of the failure when a failure or an abnormal symptom of the energy storage system 100 is detected. Preferably, the log information is set to be output and provided only in the administrator mode.

The manager setting step S300 will be described with reference to FIG. 5 attached hereto. 5 is a flowchart showing a setting step of the manager in the control method of the energy storage system according to the present invention.

Referring to FIG. 5, the manager setting step S300 includes a monitoring step S310 of monitoring the energy storage system 100 according to the set control value, a manager connection step S310 for confirming the connection of the manager through the ID and password, A setting mode output step S330 of operating in an administrator mode in which a control value can be set after the manager connection step S320 and a control mode input step S330 of storing a control value input in the setting mode output step S330, And a control value storing step (S340).

In the monitoring step S310, the control unit 157 controls the measuring unit 154, the program driving unit 153, the log recording unit 152, the timer 155, and the shutdown driving unit according to the set conditions, And monitoring information is stored in the storage unit 158. FIG.

The manager connection step S320 is a step in which the controller 157 confirms an ID and a password to be connected through the right switch 140 or the communication unit 130. [ Here, the administrator inputs an ID and a password through the terminal connected to the communication unit 130 to request a connection in the administrator mode, or selects the privilege switch 140.

The terminal connected to the communication unit 130 may be a terminal connected through a connector in the field or a terminal connected remotely via the Internet. The rights switch 140 is a switch installed in the energy storage system 100.

When the right switch 140 is turned on, the control unit 157 outputs an input window for requesting an ID and a password through the display 120. After the ID and password input through the input unit 110 are input, If it matches the ID and password of the administrator set by the user registration unit 151, the connection is granted as an administrator mode.

Alternatively, if the ID and password inputted through the communication unit 130 match the ID and password of the administrator set in the user registration unit 151, the control unit 157 permits the connection as an administrator mode.

The setting mode output step S330 may be performed after the manager connection step S320 is performed by the controller 157 through the display 120 or the communication unit 130 as an administrator mode, Mode. Here, the setting mode may include a manufacturer's description of the energy storage system (e.g., shutdown setting, alarm conditions) or external exposures, or log information of the user, It is activated only when connected as the ID and password of the user.

Accordingly, the administrator can set and / or update the measurement data, program installation and / or update of the measurement unit 154, confirmation of the log recording information, change or new input of the control value, (Such as checking the charge rate and status of each battery pack), changing control values to set anomaly detection conditions and shutdown conditions, changing user registration information, and setting permissions. have.

The control value storage step S340 is a step of storing the control value input in the setting mode output step S330. The control unit 157 stores control values and other input information input through the input unit 110 or the communication unit 130.

The driving step S500 of the energy storage system will be described in detail with reference to FIG. FIG. 6 is a flowchart illustrating a driving method of an energy storage system in a method of controlling an energy storage system according to the present invention.

6, a driving step S500 of the energy storage system includes a setting mode S410 of the manager mode, a measuring mode S420 of selecting a measurement mode per hour in the setting mode S410 of the manager mode, And a shutdown mode step S430 for selecting the shutdown mode in the setting of the manager mode (S410).

The measurement mode step S420 includes a measurement mode selection step S421 for selecting a measurement mode, a measurement step S422 for measuring within a set time, and a measurement step S422 for counting the time set after the measurement step S422, A data output step S424 for outputting data when counting of the set time is completed in the set time determination step S423; and a data output step S424 for storing the measured data, And a storing step S425.

The shutdown step S430 includes a measurement step S431 for measuring an abnormality according to the control value set in the setting step S410 and an abnormality detection step S432 for detecting an abnormality corresponding to the condition set in the measurement step S431 A shutdown determination step S433 for determining whether the shutdown condition is satisfied in the abnormality detection step S432 and an off step S434 for turning off the shutdown condition if the shutdown condition is satisfied in the shutdown determination step S433 And an alarming step S435 for issuing an alarm if the shutdown condition is not satisfied in the shutdown determination step S433.

That is, the driving step (S400) of the energy storage system according to the present invention is operated as the time measuring mode (S420) and the shutdown mode (S430) according to the conditions set in the manager setting step (S410). In this case, the measurement time period (S420) is set so that the measurement time period is set and monitored in the manager mode as the storage unit requires a large amount of capacity at the time of measuring the specific parameters continuously as described above.

In addition, if the shutdown mode (S430) corresponds to a condition set in the administrator mode (for example, overdischarge, short, overheat), the system can be turned off collectively as the highest order command currently being driven by another command, This is to prevent breakage or failure of the storage system.

First, the time measurement mode (S420) may select the time measurement mode in the setting step (S410). That is, when the user requests the manager to make an item to be measured (for example, the output current of the charging unit 161), the manager may select any one of the communication unit 130, the right switch 140, and the input unit 110 And proceeds to the manager setting step through one to select the measurement mode per hour.

In the measurement mode selection step S421, when the time selection signal and the measurement item are inputted through the input unit 110 and the communication unit 130 in the setting step S410, the controller 157 stores the measurement mode and the measurement item in the storage unit 158 .

In the measuring step S422, the controller 157 confirms the time selection signal and the measurement item stored in the storage unit 158 and drives the timer 155. [ The control unit 157 controls the measurement unit 154 to measure the set item for a predetermined time. The measuring unit 154 measures the item during the counting time of the timer 155 and applies the measured item to the controller 157.

The set time determination step S423 is a step in which the controller 157 receives a time counting signal of the timer 155 and determines whether a predetermined time has elapsed.

In the output step S424, the controller 157 completes the measurement of the measurement unit 154 when the counting of the set time of the timer 155 is completed in the set time determination step, (Step 120). The control unit 157 drives the program driving unit 153 to record and output measurement data of the measurement unit 154 through a commonly known document creation program.

In the storage step S425, the control unit 157 records measurement data of the measurement unit 154 as a document creation program, and stores the measurement data in the storage unit 158 as a file. The control unit 157 transmits the measurement file stored in the storage unit 158 to the terminal connected through the communication unit 130. [ Therefore, the user can receive measurement data of his / her desired item as a file of a commonly used document creating program, which is very easy to manage and utilize.

If the control unit 157 determines that a control value (for example, a shutdown condition and an alarm condition) including the items and conditions set in the setting step S410 is set, Measure and monitor items.

That is, the measuring step S431 is a step in which the controller 157 controls the measuring unit 154 according to the control value set in the setting step S410. The controller 157 controls the measuring unit 154 to sense the individual output voltages and currents of the one or more battery packs included in the charging unit 161 and the charging rate and the temperature. The voltage, current, and temperature are detected by a known technique (for example, a voltage sensor, a current sensor, and a temperature sensor).

The abnormality sensing step S432 is a step in which the controller 157 receives a measurement signal of the charging rate, the voltage and the current value measured in the measuring step and detects an abnormality exceeding the set reference value. Here, the reference value is set in the setting step S410, and the controller 157 receives and compares the reference value set in the setting step S410 with the measurement signal of the measuring unit 154 to determine whether or not it is abnormal.

The shutdown determination step S433 is a step of determining whether the abnormality detected in the abnormality sensing step S432 corresponds to a shutdown condition. If the reference value of the filling rate is 10% or less and the shutdown condition is set to 5% or less in the abnormal detection condition, if the filling rate is less than the reference value and 5% Proceed with the alarm step. Alternatively, the controller 157 proceeds to the off step if the charge rate is less than 5% and falls under the shutdown condition.

That is, the control unit 157 maintains the currently executed control value as it is in the abnormality detection condition. If the shutdown condition is satisfied, the control unit 157 forcibly terminates the command based on the current control value and executes the shutdown command do.

In step S435, the controller 157 controls the alarm unit 170 to issue an alarm if the abnormality detection condition does not correspond to a shut down condition in the shutdown determination step S433 . The control unit 157 controls the alarm unit 170 to alert the energy storage system 100 of an abnormality as an acoustic signal and / or a light emission signal.

In the off step S434, the controller 157 controls the power supply line of the charging member 160 to be cut off. To this end, the control member 150 preferably further comprises switching means (not shown) for switching the power supply line connected to the external system and the internal load.

As described above, according to the present invention, in the control apparatus of the energy storage system, the authority to change a control value or input (for example, a measurement item, an abnormality detection condition, a shutdown condition) It is possible to prevent a breakdown due to the leakage of the technology and the erroneous operation of the unqualified person.
