Description

Unidirectional charging control device and method for electric vehicle charger {APPARATUS AND METHOD FOR UNIDIRECTIONAL CHARGING CONTROL OF ELECTRIC VEHICLE CHARGER}

The present invention relates to a charging control device and method for an electric vehicle charger, and particularly to a device and method for controlling unidirectional charging of an electric vehicle charger.

As the spread of electric vehicles gains momentum, the number of electric vehicles is rapidly increasing every year, and accordingly, the number of electric vehicle chargers is also increasing at a very fast rate, and the continuously increasing charging of electric vehicles affects the system and power supply and demand.

V1G (aka one-way charging control) is designed to minimize the impact of increasing electric vehicle charging demand on power supply and system operation by controlling the charging speed of electric vehicles when power supply conditions change rapidly due to peak demand or sudden changes in volatile renewable energy generation. It is a technology that stabilizes power supply and demand by controlling .

Unlike existing slow charging, which stores electricity in the system at a constant rate until charging once charging begins, V1G smart charging has the advantage of being able to adjust the charging speed in real time according to power supply and demand conditions.

Korean Patent No. 10-2452000 discloses a distribution system management device that monitors the power generation of the distribution system and new and renewable energy and issues demand response events according to the status information of the distribution system, and analyzes customer types according to demand response events to provide electricity. A drive-through V1G management server that calculates a car call goal and requests event participation from the electric vehicle use terminal according to the calculated call goal, and responds to the event participation request to visit the drive-through store to participate in the event at the target time. A V1G service system for a drive-through store that includes an electric vehicle use terminal that operates the vehicle has been disclosed.

According to the above patent, it is possible to participate in the power trading market by using electric vehicles as demand loads in drive-thru stores equipped with wireless power charging facilities.

In this way, V1G technology is in the commercialization stage by conducting verification through multiple research and development.

However, because this V1G technology is based on power control, there was a problem that existing chargers could not participate in V1G. In other words, because only chargers equipped with a power control function can participate in V1G, chargers installed to date cannot participate in V1G. As a result, the number of chargers that can participate is very small, which greatly reduces the effectiveness of V1G.

In addition, when a power control function is installed to perform V1G, the price of the charger increases significantly, which increases the burden on charging operators.

Below, embodiments of the present invention will be described with reference to the attached drawings, and will be described in detail so that those skilled in the art can easily practice the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Meanwhile, in order to clearly explain the present invention in the drawings, parts not related to the description are omitted, and similar parts are given similar reference numerals throughout the specification. In addition, descriptions of parts that can be easily understood by those skilled in the art are omitted even if detailed descriptions are omitted.

Throughout the specification and claims, when it is said that a part includes a certain component, this does not mean excluding other components, but may further include other components, unless specifically stated to the contrary.

Figure 1 is a system configuration diagram of an electric vehicle charging system to which a unidirectional charging control device for an electric vehicle charger is applied according to an embodiment of the present invention. Referring to Figure 1, the electric vehicle charging system to which the electric vehicle charger unidirectional charging control device of the present invention is applied includes a distribution management system (ADMS: Advanced Distributed Management System) (10), a V1G system (100), and a charger management system (EVC: Electric). It may include a Vehicle Charging system (20), and an electric vehicle charging terminal (30, 40).

The distribution management system (ADMS: Advanced Distributed Management System, hereinafter referred to as 'ADMS') (10) is a system that manages load information for each distribution line (DL) and controls switches. By transmitting integrated load information to the V1G system 100, basic information for controlling charger power is provided.

The charger management system (EVC: Electric Vehicle Charging system, hereinafter referred to as 'EVC') (20) manages chargers and charging infrastructure for charging electric vehicles and provides charging customer service. In particular, the EVC system 20 receives a charging control schedule from the V1G system 100, manages the charging amount or charging time for each charger based on the charging control schedule, and monitors the charging control status of each charger.

The V1G system 100 is a system that controls the operation of electric vehicle chargers by generating a charging control schedule for one-way charging control (V1G), and is linked to the ADMS 10 and the EVC system 20 to control one-way charging of electric vehicle chargers ( V1G) is performed. To this end, the V1G system 100 receives and analyzes distribution load information from the ADMS 10 to determine peak times, etc., and when it is determined that power control is necessary, generates the charging control schedule and transmits it to the EVC system 20. do.

The electric vehicle chargers 30 and 40 provide an interface with the electric vehicle and charge the electric vehicle connected with a charging cable. To this end, the electric vehicle chargers 30 and 40 are controlled by the EVC system 20 and transmit the charging results to the EVC system 20.

In particular, the electric vehicle chargers 30 and 40 can participate in the V1G service by receiving a charging control schedule from the EVC system 20. For this, it must be configured as a 7kW slow charger, require prior approval from the customer, and perform system analysis. When attempting to perform V1G through , the electric vehicle must be charging (except when the electric vehicle is connected but charging is complete).

Meanwhile, the electric vehicle charger (aka, V1G charger) 30 equipped with a power control function (i.e., power control device) controls the charging amount for each time period according to the charging control schedule (i.e., charging amount control schedule) for controlling the charging amount, thereby controlling the charging amount of the V1G. The electric vehicle charger 40 that participates in the service and does not participate in the V1G service can participate in the V1G service by controlling the charging time according to the charging control schedule (i.e., charging time control schedule) for controlling the charging time. In the latter case, the charging amount per unit time is the same.

In the example of Figure 1, the electric vehicle charger 30 is controlled by the 'charge amount control schedule' as illustrated in the figure, charging 100% of the chargeable amount of power from 12:00 to 12:30, and then Afterwards, it can be controlled to charge only 50% of the chargeable amount of power, and the electric vehicle charger 40 controls charging according to the 'charging time control schedule' as illustrated in the drawing, from 12:00 to 12:20. It can be controlled to perform charging, stop charging from 12:20 to 12:50, then perform charging again from 12:50 to 1:30, and stop charging after 1:30. there is.

Figure 2 is a schematic block diagram of a one-way charging control device for an electric vehicle charger according to an embodiment of the present invention. Referring to Figures 1 and 2, the one-way charging control device (i.e., V1G system) 100 of an electric vehicle charger according to an embodiment of the present invention includes an ADMS I/F (110), an EVC I/F (120), It includes a load monitoring unit 130, a charging control schedule generating unit 140, and a control unit 150.

ADMS I/F 110 provides an interface with ADMS 10, and receives distribution load information including power reserve ratio and total power usage from ADMS 10. At this time, the received distribution load information refers to load information for each distribution line (DL) and integrated load information, and can be used as basic information to control electric vehicle charger power use in the future.

The EVC I/F 120 provides an interface with the EVC system 20, and sets the charging control schedule to be delivered to the electric vehicle chargers that wish to participate in the V1G service among the electric vehicle chargers managed by the EVC system 20. It is transmitted to (20), and load control information for each electric vehicle charger participating in the V1G service can be received from the EVC system (20).

The load monitoring unit 130 monitors the distribution load information collected from the ADMS I/F 110 and determines whether the distribution load information satisfies preset load control conditions. For this purpose, the load monitoring unit 130 stores a preset power reserve rate reference value and a preset total power usage reference value, and the power reserve included in the distribution load information is less than the power reserve rate reference value or is included in the distribution load information. If the total power usage exceeds the total power usage reference value, it can be determined that the load control condition is satisfied.

For example, the load monitoring unit 130 determines that it is a peak time when the power reserve ratio of the collected load is less than a preset percentage (e.g., N%) or the total power usage is more than a preset capacity (e.g., M mW). It may be determined that peak or load control is necessary.

Alternatively, the load monitoring unit 130 may decide to perform power control at a set time according to the manager's order.

When the load monitoring unit 130 determines that the load control condition is satisfied, the charging control schedule generator 140 calculates the load control amount, which is the total load to be controlled, and distributes the load control amount to the electric vehicle chargers. A charging control schedule is created, and different charging control schedules are created depending on the type of electric vehicle charger to which the charging control schedule will be applied.

To this end, the charging control schedule generator 140 must first collect information on at least one electric vehicle charger that can participate in load control. That is, the charging control schedule generator 140 collects information on at least one electric vehicle charger that can participate in load control among the electric vehicle chargers managed by the EVC system 20 through the EVC I/F 120, , Among the electric vehicle chargers for which the user's pre-approval information to participate in load control is registered, charger identification information, whether a power control device is installed, and controllable individual load information are collected from each of at least one slow charger that is currently charging. Collect. At this time, the ‘current’ refers to the time when V1G is to be performed through system analysis.

In this way, when information on at least one electric vehicle charger capable of participating in load control is collected, the charging control schedule generator 140 generates the charging control schedule based on the collected information on the electric vehicle chargers. That is, the charging control schedule generator 140 classifies the collected electric vehicle chargers into chargers equipped with a power control device (aka, V1G chargers) and chargers without a power control device (aka, general slow chargers), Different charging control schedules are created to control the charging amount of each of these.

That is, the charging control schedule generator 140 generates a charging amount control schedule that sets the charging power amount for each time period to control the load using the V1G charger 30 equipped with a power control device, and a general charger not equipped with a power control device. To control the load using the slow charger 40, a charging time control schedule that sets the charging on/off time can be created. At this time, the charging control schedule generator 140 may refer to the collected individual load information for each electric vehicle charger.

For example, when performing V1G for 2 hours, according to the charging amount control schedule, '00:00 3.5kW / 00:20 4.2kW / 00:50 2.1kW / 01:20 5.6kW / 01:50 7kW' You can also control the charging amount by time period. However, this charging control method can only participate in chargers capable of charging control, and can be processed through the V1G charger 30 illustrated in FIG. 1.

Meanwhile, according to the charging time control schedule, in order to obtain the same charging control effect as the above example, '0:00 ~ 00:10 / 00:20 ~ 00:38 / 00:50 ~ 01:00 / 01:20 ~ You can control the charging on/off time, such as '01:44 / 01:50 end'. This uses the part where the charger determines the end of charging because the slow charger does not communicate with the vehicle. However, in this case, a problem may arise where chargers tied to the same distribution network control charging at the same time, so the time can be shifted by the number of chargers. For example, when the charging time schedule of any first slow charger is set as in the example above, the charging time schedule of another second slow charger starts from 0:03 with the starting point shifted by 3 minutes, ' It can be scheduled as follows: 0:03 ~ 00:13 / 00:23 ~ 00:41 / 00:53 ~ 01:03 / 01:23 ~ 01:47 / 01:50 end'.

The control unit 150 controls the overall operation of the one-way charging control device 100 of the present invention based on a preset one-way charging control device control algorithm of the electric vehicle charger. In particular, the control unit 150 can control the EVC I/F 120 to transmit the charging control schedule to the corresponding electric vehicle charger.

In addition, the control unit 150 collects charging control schedule execution information and user information for each of the electric vehicle chargers through the EVC I/F 120, and provides payment to the corresponding user based on the charging control schedule execution information. After calculating the incentives, you can provide that information. To this end, the control unit 150 stores in advance the incentive payment standard according to the charging control schedule execution information, matches the charging control schedule execution information of each electric vehicle charger to the incentive payment standard, and provides incentives to be paid to the corresponding users. It can be calculated. Additionally, the control unit 150 may pay the determined incentive using a normal incentive payment method.

3 to 5 are processing flowcharts for a unidirectional charging control method of an electric vehicle charger according to an embodiment of the present invention. With reference to FIGS. 1 to 5, a unidirectional charging control method of an electric vehicle charger according to an embodiment of the present invention will be described as follows.

First, in step S110, the ADMS I/F 110 collects distribution load information including the power reserve ratio and total power usage from the ADMS 10. At this time, the received distribution load information refers to load information for each distribution line (DL) and integrated load information, and can be used as basic information to control electric vehicle charger power use in the future.

In step S120, the load monitoring unit 130 monitors the distribution load information and determines whether the distribution load information satisfies preset load control conditions. To this end, the load monitoring unit 130 stores a preset power reserve reference value and a preset total power usage reference value, and then, in step S121, compares the power reserve rate included in the distribution load information with the preset power reserve reference value. , In step S122, the total power usage included in the distribution load information is compared with a preset total power usage reference value. In addition, in step S123, the load monitoring unit 130 determines whether to control the load based on the comparison result, if the power reserve ratio included in the distribution load information is less than the power reserve ratio reference value or If the total power usage exceeds the total power usage standard value, load control can be determined.

In step S130, the charging control schedule generator 140 calculates the load control amount, which is the total load amount to be controlled, in response to the load control decision. For this purpose, the charging control schedule generation unit 140 receives the result of determining whether to control the load from the load monitoring unit 130, and is also provided with power reserve ratio information or total power usage information, and the power reserve ratio is insufficient compared to the reference value. The load control amount can be calculated by referring to information on the degree or total power usage exceeded compared to the reference value.

In step S140, the charging control schedule generator 140 generates a charging control schedule for distributing the load control amount calculated in step S130 to the electric vehicle chargers, depending on the type of electric vehicle charger to which the charging control schedule will be applied. Create different charging control schedules.

To this end, the charging control schedule generator 140 collects information on at least one electric vehicle charger capable of participating in load control in step S141, and participates in load control among the electric vehicle chargers managed by the EVC system 20. Collect information on at least one available electric vehicle charger. In particular, in step S141, the charging control schedule generator 140 generates charger identification information from each of at least one slow charger currently in progress among the electric vehicle chargers for which the user's pre-approval information for participating in load control is registered, Information on whether a power control device is installed and controllable individual loads can be collected.

In step S142, the charging control schedule generator 140 classifies the electric vehicle chargers based on the collected information and classifies the electric vehicle chargers according to whether or not the power control device is mounted.

Then, in step S143 or step S144, the charging control schedule is generated based on the collected electric vehicle charger information, that is, based on a classification result of the electric vehicle charger.

To this end, in step S143, in order to control the load using an electric vehicle charger equipped with a power control device (i.e., a V1G charger), the charging power amount for each time period of each of the V1G chargers is based on the individual load information of each of the V1G chargers. Create a charging amount control schedule that sets.

Meanwhile, in step S144, in order to control the load using an electric vehicle charger not equipped with a power control device (i.e., a general slow charger), each of the general slow chargers is based on the individual load information of each of the general slow chargers. Create a charging time control schedule that sets the charging on/off time.

In step S150, the control unit 150 controls the EVC I/F 120 and transmits the charging control schedule to the corresponding electric vehicle charger. That is, in step S150, the control unit 150 transmits a charging amount control schedule to the V1G charger and a charging time control schedule to the general slow charger.

In addition, the V1G charging control device of the present invention reads whether or not the provided charging control schedule is executed, and provides incentives according to the execution results to users (i.e., electric vehicle charger operators) who faithfully execute the charging control schedule. , participation in V1G services can be encouraged.

In this way, the present invention can secure enough chargers that can participate by performing charging control for V1G service using existing chargers, thereby maximizing the effect of charging control and reducing device replacement costs. There are features that can save you money.

In addition, the present invention can control the charging amount by using the time schedule of the charger but limiting the charging time by charging start and charging stop, and as a result, the control success rate is relatively high compared to the method of controlling the amount of power.

In addition, the present invention performs time-based charging control using the time schedule of the slow charger, so that the charging amount can be controlled without adopting a fast charger equipped with an expensive power control device, thereby reducing the price of the slow charger. There are features that allow it to be maintained.

In addition, as the power market changes from TSO (Transmission System Operators) to DSO (Distribution network Operators), V1G may become a more useful power control option for each region in order to manage electricity supply and demand in each region. At this time, the technology of the present invention can be used to expand the number of chargers that can participate in the V1G service, thereby facilitating regional power supply and demand management.
