Description

Cable-integrated control box, charging control method thereof, and recording medium recording a computer readable program for executing the above method. FOR EXECUTING THE METHOD}

The present invention relates to an integrated cable control box for an electric vehicle and a charging control method using the same. More particularly, the integrated cable control for a vehicle that can automatically change the charging setting according to a power situation of a house supplying power for charging an electric vehicle. It relates to a box and a charging control method using the same.

In general, an electric vehicle is provided with an onboard charger (OCC) for converting AC power supplied from the outside into direct current power, thereby charging the high voltage battery of the electric vehicle using the power supplied from the outside. Can be.

In this case, the electric power for charging the electric vehicle may be supplied from a charging facility or a home power source. For this purpose, an in-cable control box (ICCB) which performs a control and safety function regarding the electric vehicle charging. Is being used.

Such a cable-integrated control box is provided with a plug connected to a charging facility or a home power supply and a connector connected to an inlet of a vehicle to be charged, and supplying or blocking commercial power according to the charging information transmitted from the above-described charging device. When the leakage current is detected, the function to stop charging.

FIG. 1 is a diagram illustrating an example of charging an electric vehicle through a cable integrated control box from a power supply of a general household. In FIG. 1, an integrated cable control box receives power from an AC outlet of a house to charge an electric vehicle through an inlet of the vehicle.

On the other hand, the household electrical equipment for supplying power to the electric vehicle is set so that the power supply is cut off when a short circuit. The setting of earth leakage breakers in homes to cut off the power supply is generally different from country to country, and even in a single country, the earth leakage breaker rated current differs from building to building within a single country.

Accordingly, the cable-integrated control box can adjust the charging setting. When the earth leakage breaker allowable current of the building is 16A, the ICCB charging setting can be adjusted to 16A. In this case, the ICCB can transmit the chargeable current amount information 9.6A (for example, 16A X 60% = 9.6A) to the OBC, and the marginal load in the home during charging of the electric vehicle is obtained by subtracting the ICCB charging current from the building's earth leakage breaker allowable current. 6.4 A (16 A-9.6 A = 6.4 A).

As another example, when the earth leakage breaker allowable current of the building is 12A, the ICCB charging setting may be set to 12A. In this case, ICCB can transmit 7.2A (eg 12A X 60% = 7.2A) of chargeable current amount information to OBC, and the marginal load in the home during charging of electric vehicle is obtained by subtracting the ICCB charge current amount from the earth leakage breaker allowable current of the building. 4.8A (e.g. 12A-7.2A = 4.8A).

However, when the ICCB is set to 16 A in the home where the earth leakage breaker allowable current is 12 A, the ICCB can transmit 9.6 A (for example, 16 A X 60% = 9.6 A) of chargeable current information to the OBC, The marginal load will be 2.4A (eg 12A-9.6A = 2.4A) minus the ICCB charging current from the building's earth leakage breaker allowable current. In this case, if the load in the home increases above 2.4A, the possibility of charging interruption is high due to the earth leakage breaker operation.

In addition, when ICCB charging is set based on 12A with low leakage current permitting to increase charging stability, ICCB can be charged with OBC in the assumption that the earth leakage breaker allowable current is 16A 7.2A (e.g. 12A X 60% = 7.2A) can be delivered, and the allowable load in the home during charging of the vehicle will be 8.8A (eg 16A-7.2A = 8.8A) minus the ICCB charging current of the building's earth leakage breaker allowable current. In this case, a problem arises in that the time required for the shock absorbing of the electric vehicle is excessively increased.

In this case, the communication unit 110 may communicate charging information with the earth leakage breaker of the home and the OBC of the vehicle by using PLC communication.

The controller 120 calculates and sets charging information to be charged by the connected electric vehicle according to the allowable current information. When the earth leakage breaker allowable current information is provided to the ICCB at home, the charging information of the ICCB is set according to the earth leakage breaker allowable current information.

The positioning unit 130 obtains position information of the cable integrated control box 100. At this time, the current position information of the ICCB is primarily detected by receiving the GPS information, and if the GPS reception is not possible, can be secondarily confirmed by the method such as CDMA, WIFI, ZIGBee, beacon.

The memory unit 140 stores leakage current blocking allowable current information corresponding to the location information. For this purpose, the memory unit 140 may maintain a table of rated current information (leakage current blocking current) for each country (region).

When the communication unit 110 does not receive the allowable current information, the controller 120 may set the charging information according to the earth leakage blocking allowable current information stored corresponding to the location information.

When the earth leakage breaker allowable current information is not provided to the ICCB in the home, the ICCB charging information is compared by comparing the position information detected by the positioning unit 130 with the rated current information by country (region) stored in the memory unit 140. To set.

According to such a structure, even if the permission information of an earth leakage breaker cannot be received, it is possible to acquire the earth leakage blocking permission information of a building using the positional information.

The user input unit 150 receives safety factor information for calculating charging information together with allowable current information. As a configuration for inputting control information by a user, the configuration may be implemented in the form of a touch screen or a button. 2 illustrates an example in which the user input unit 150 is integrated with the display unit 160 in the form of a touch screen. According to such a configuration, it is possible to change the charging information setting of the cable-integrated control box according to the charging needs of the user as well as the power installation situation of the building.

The display unit 160 is configured to output ICCB charging state information. When the charging stop occurs while charging the electric vehicle according to the safety factor information input from the user input unit 150, the display unit 160 may output a safety factor change request output.

According to such a configuration, when a situation occurs in which charging cannot continue even when the charging setting is made according to a user's needs, the user can be notified of such a situation.

In addition, the controller 120 calculates charging information by automatically changing the input safety factor to a preset safety mode when charging stops while charging an electric vehicle according to the safety factor information of the initial setting mode input from the user input unit 150. can do. According to such a configuration, even when a user cannot take an action or even when no action is taken, a response to the charging stop situation can be performed.

In addition, the communication unit 110 may further receive real-time load information of the building from the building to receive power, and the control unit 120 may calculate and set the charging information to be charged to the connected vehicle according to the real-time load information. According to such a configuration, the electric vehicle can be charged more efficiently by reflecting the real-time power situation of the building.

In addition, when the communication unit 110 does not receive the allowable current information and the real-time load information, and the positioning unit 130 does not acquire the position information of the cable-integrated control box, the control unit 120 returns the latest charging information. Can be set.

According to such a configuration, even when there is a problem in a communication situation or the like, it is possible to increase the probability that the electric vehicle can be effectively charged by using the most recent charging information.

In addition, when the allowable current information corresponding to the location information is not stored, the control unit 120 may set the charging information according to the user's initial setting mode, and the memory unit 140 may complete the electric charging to the electric vehicle without interruption. In this case, current information at the time of charging may be stored according to the location information.

According to this configuration, even when there is no preset information, the charging of the electric vehicle can be performed by using the user setting value. If the charging is successful by the user setting value, the setting value is allowed in the position afterwards. It can be used as current information.

3 is a table illustrating an example of charging current setting performed by the controller according to different situations. 3 is a table showing examples of charging current setting performed by the control unit for each situation according to whether an earth leakage breaker allowable current is received, GPS information is received, auxiliary location information is received, memory unit storage information is matched, and a real-time usage load of the home is used. .

The safety factor (60%) may vary depending on the user's initial set charging mode (stable charging priority / fast charging priority). For example, it may be set to 60% in the stable charging priority mode (default setting) and 80 to 90% in the fast charging priority mode.

At this time, the mode change request menu can be displayed when charging stops during charging in the quick charge priority mode, and can be automatically changed to the stable charge priority mode when the mode change input is not input from the user within a predetermined time (display of charging mode change completed). . In addition, when charging stops while charging in the fast charging priority mode, the automatic charging to the stable charging priority mode may be automatically changed (charging mode change complete display).

In addition, when the charging current is set in the situation 3 and the situation 5 not stored in the memory unit 140, the safety factor may be changed according to the user's initial setting mode, and the situation 3 and the situation 5 are not stored in the memory unit 140. In the case where the charging is completed without any problem, the charging position information and the current information used for the charging may be newly stored in the memory unit.

4 is a schematic flowchart for performing a charging control method of a cable integrated control box according to an embodiment of the present invention. 4 illustrates an example of the charging current setting according to the situation illustrated in FIG. 3.

First, it is determined whether the ground fault breaker allowable current information is receivable (S110), and if receivable (situation 1), the charging current is set to allowable current x 60% (S160).

If it is impossible to receive, after operating the first positioning unit (S120), it is determined whether the GPS information can be received (S130), and if it is possible to check the memory unit storage table (S140) after the current leakage blocking allowance current position Check (S150), if confirmed (situation 2) sets the charging current to the allowable current x 60% (S160).

In addition, when the ground fault breaker allowable current information cannot be received and the GPS information is received to check the memory unit storage table (S140), but the ground fault breaker allowable current of the current position is not confirmed (situation 3), the charging current is stored recently. The charging current is set (S190).

In this case, it may be implemented not to set the recently used charging current but to set the preset default charging current, or may be set according to the charging information of the nearest position among the tables stored in the memory unit.

The memory unit stores all the history of the charging and the corresponding position information and sets the charging current according to the charging information proceeded from the closest position where the charging was performed.

In addition, it is impossible to receive the earth leakage breaker allowable current information and GPS information, and after confirming the current position by other positioning means (S170), it is determined that the position information is received (S180), and the position information is received and the memory unit storage table is collated as a result. If the earth leakage blocking allowable current of the current position is confirmed (situation 4), the charging current setting is set to allowable current x 60% (S160).

In addition, when the earth leakage breaker allowable current information and GPS information cannot be received and the current position is checked by another positioning means, and the memory unit storage table is checked (S140), the earth leakage breaker allowable current is not confirmed (Situation 5). , The charging current is set to the recently used stored charging current (S190).

In this case, as in the situation 3, the situation 5 may be implemented to set the preset default charging current instead of the recently used charging current. It may be implemented to set accordingly.

The memory unit stores all the history of the charging and the corresponding position information and sets the charging current according to the charging information which has been performed at the closest position where the charging was performed.

In addition, when real-time confirmation of the use load in the home is possible (situation 6), the charging current is set to allowable current-use in the home.

Finally, the set information is provided to the OBC. When the charge setting information of the ICCB is transferred to the OBC, the OBC receives the charging current from the power supply in accordance with the charge setting information.

According to the present invention, the charging information of the ICCB can be set differently in consideration of the case where the allowable current capacity of the earth leakage breaker in the home is different for each country and region in charging the electric vehicle with the AC power for the home using the ICCB.

According to the present invention, if the charging information of the ICCB is set differently according to the allowable current capacity of the earth leakage breaker, the electric vehicle can be charged in all countries through one ICCB. In addition, since the optimal charging current is available where charging is currently performed, charging efficiency is increased.

Although the present invention has been described in terms of some preferred embodiments, the scope of the present invention should not be limited thereby, but should be construed as modifications or improvements of the embodiments supported by the claims.
