[0026] Figure 1 Schematic diagram showing a wireless charging road environment according to an exemplary embodiment of the present invention. Figure 1 , a wireless charging road 1 for supplying electric power for wireless charging to a moving vehicle can be implemented on a road on which the vehicle is traveling. Specifically, the wireless charging road 1 can be set on one lane of the road. As an example, the wireless charging road 1 can be set on the outermost lane of the road lanes. Of course, the location where the wireless charging road 1 is set is not limited thereto, and the wireless charging road can be set in various ways according to the implementation form.
[0027] At least one infrastructure for providing the state information of the power grid to the vehicle may be installed on the wireless charging road 1. Thus, the infrastructure may provide the state information of the power grid to the target vehicle based on the request of the vehicle. Herein, the state information of the power grid may include information about the power supply state of the power grid, information about the electricity price for each time interval, etc.
[0028] The vehicle may have a charging management device 100 configured to manage the battery status and charging of the vehicle while the vehicle is traveling. Thus, the charging management device 100 may be configured to receive status information of the power grid from the infrastructure on the wireless charging road 1 while the vehicle is traveling, and may be configured to generate a charging plan with reference to the received status information of the power grid. Specifically, the charging management device 100 may be configured to generate a charging plan with reference to the user's mode of using the wireless charging road 1. The charging management device 100 may be configured to generate a charging plan with the lowest cost with reference to the power supply status of the power grid and the electricity price for each time interval, and may be configured to perform charging control of the vehicle battery based on the generated charging plan.
[0029] Herein, the charging management device 100 may be configured to generate a charging plan that does not include a time interval in which the power supply state is less than a reference level. The charging management device 100 according to an exemplary embodiment of the present invention may be implemented in a vehicle. Specifically, the charging management device 100 may be configured integrally with a controller in the vehicle, or may be implemented as a separate device to be connected to a control unit of the vehicle through a separate connection device. Herein, the charging management device 100 may be connected to the engine and motor of the vehicle for operation, and may be connected to a controller configured to operate the engine or motor.
[0030] Therefore, the reference Figure 2 A detailed description of the configuration and operation of the charging management device 100 is given in accordance with an exemplary embodiment of the present invention. Figure 2 A block diagram showing a configuration of a charging management device for a vehicle according to an exemplary embodiment of the present invention. Figure 3 is a schematic diagram illustrating the operation of the charging management device for a vehicle according to an exemplary embodiment of the present invention.
[0031] Reference Figure 2 The charging management device 100 may include: a user DB management device 110, a user DB 120, a driving environment management device 130, a power grid state recognition device 140, a battery state recognition device 150, and a controller 160. The user DB management device 110 may be configured to construct and store the user DB 120, and manage the user profile stored in the user DB 120. As an example, the user DB management device 110 may be configured to utilize a user DB for Figure 1 The user DB 120 is constructed based on the user profile of the usage pattern of the wireless charging road 1 .
[0032] Herein, the usage pattern of the wireless charging road 1 may include a usage time interval of the user using the wireless charging road 1 and / or information about the daily average usage time of the wireless charging road 1, etc. Herein, the user DB 120 may be constructed based on weekly data, which is obtained by recording the usage time interval of the wireless charging road 1 and / or information about the daily average usage time of the wireless charging road 1 every week.
[0033] Will refer to Figure 3 A detailed exemplary embodiment of the user DB 120 is described. Figure 3 , users used wireless charging road 1 during the time periods from 07:00 to 08:00 and from 18:00 to 19:00 on Monday, and the average daily usage time of wireless charging road 1 was 2 hours.
[0034] In addition, the user used the wireless charging road 1 between 08:00 and 09:00 and 18:00 and 19:00 on Tuesday, and the average daily usage time of the wireless charging road 1 was 2 hours. In addition, the user used the wireless charging road 1 between 08:00 and 09:00 and 18:00 and 19:00 on Thursday, and the average daily usage time of the wireless charging road 1 was 2 hours. In addition, the user used the wireless charging road 1 between 08:00 and 09:00 and 18:00 and 19:00 on Friday, and the average daily usage time of the wireless charging road 1 was 2 hours.
[0035] In addition, the user uses the wireless charging road 1 from 13:00 to 14:00 on Saturday, and the average daily usage time of the wireless charging road 1 is 1 hour. In addition, the user uses the wireless charging road 1 from 11:00 to 13:00 and from 19:00 to 21:00 on Sunday, and the average daily usage time of the wireless charging road 1 is 4 hours. Meanwhile, the user does not use the wireless charging road 1 on Wednesday.
[0036] Figure 3 The user DB 120 shown can be updated with data of the corresponding day of the week when the vehicle travel is completed, and can be updated with weekly data every week or every month. The user DB management device 110 can be configured to update the information stored in the user DB 120 with weekly data within a predetermined period of time. As an example, the user DB management device 110 can be configured to update the information stored in the user DB 120 with weekly data recorded every week within a month.
[0037] Specifically, the user DB management device 110 may be configured to update the information stored in the user DB 120 using the average value of the weekly data within a predetermined period of time. When multiple users use the vehicle, the user DB management device 110 may be configured to build, store, and manage a DB for each user. The driving environment management device 130 may be configured to manage the usage pattern of the wireless charging road 1 for the user while the vehicle is driving.
[0038] Herein, the driving environment management device 130 may be configured to obtain and manage the day of the week when the wireless charging road 1 is used and information about the time interval of using the wireless charging road 1 while the vehicle is traveling. In addition, the driving environment management device 130 may be configured to obtain and manage information about the average time of using the wireless charging road 1 in one day. Specifically, the driving environment management device 130 may be configured to send information about the time interval of use of the wireless charging road 1 and information about the daily average use time of the wireless charging road 1 on each day of the week to the user DB management device 110.
[0039] In addition, the driving environment management device 130 may be configured to generate weekly data based on information about the use time interval of the wireless charging road 1 and information about the daily average use time of the wireless charging road 1 on each day of the week, and may be configured to send the weekly data to the user DB management device 110. As an example, when the vehicle arrives at the destination and the driving of the vehicle is completed, the driving environment management device 130 may be configured to send information about the time interval and the use time when the vehicle actually used the wireless charging road 1 while the vehicle was driving to the user DB management device 110. Thus, the user DB management device 110 may be configured to update the user DB 120 with the information about the use time interval and the use time of the wireless charging road 1, which is received from the driving environment management device 130 when the driving of the vehicle is completed.
[0040] Specifically, the user DB management device 110 may be configured to update the average usage time of the wireless charging road 1 in each time interval of a week using the information about the usage time interval and the usage time of the wireless charging road 1. For example, assuming that the usage time of the first time interval in a week is t1=[t11, t12, t13, t14, t15, t16, t17], when t1=[1, 1, 0, 1, 1, 0, 0], the average usage time of the first time interval of each week may be calculated with reference to the following equation 1.
[0041] Equation 1:
[0042]
[0043] The power grid state identification device 140 may be configured to receive power grid state information from a power grid that manages the power grid state of the wireless charging road 1. Specifically, the power grid state identification device 140 may be configured to receive the power grid state information from the power grid in real time. At the same time, the power grid state identification device 140 may be configured to request the power grid to send the power grid state information, and may be configured to receive the power grid state information from the power grid in response to the request.
[0044] When the power grid state information changes, the power grid state identification device 140 may be configured to receive the changed power grid state information from the power grid. Herein, the power grid state information may include information on the power supply state of the power grid, information on the electricity price for each time interval, and the like.
[0045] The charging management device 100 may separately include a communication module that supports a communication interface with the power grid. At the same time, the charging management device 100 may be configured to send and receive signals with the power grid via the communication module of the vehicle without having a separate communication module. Herein, the communication module may include a module for accessing a wireless network or a module for short-range communication.
[0046] Wireless Internet technologies may include: Wireless Local Area Network (WLAN), Wireless Broadband (WiBro), Wireless Fidelity (Wi-Fi), Worldwide Interoperability for Microwave Access (WiMAX), etc. In addition, short-range communication technologies may include: Bluetooth, ZigBee, Ultra Wideband (UWB), Radio Frequency Identification (RFID), Infrared Data Association (IrDA), etc.
[0047] When receiving the power supply information of the power grid, the power grid state identification device 140 can be configured to identify the power supply state of the wireless charging road 1 and the power cost of each time interval according to the power supply state in the received power supply information. Specifically, the power grid state identification device 140 can be configured to send information about the power supply state of the wireless charging road 1 and information about the power cost of each time interval according to the power supply state to the controller 160.
[0048] Meanwhile, in response to determining that the power supply information (i.e., the power supply status and / or power cost of each time interval) changes while the vehicle is traveling, the power grid status identification device 140 may be configured to send the changed power supply information to the controller 160. The battery status identification device 150 may be configured to identify the battery status of the vehicle while the vehicle is traveling. In addition, the battery status identification device 150 may be configured to identify the necessary amount of power required until the vehicle reaches the destination based on the remaining distance to the destination.
[0049] Specifically, the battery status recognition device 150 may be configured to cooperate with the navigation device of the vehicle to operate. In other words, the battery status recognition device 150 may be configured to request the navigation device of the vehicle to provide information about the remaining distance to the destination. The battery status recognition device 150 may be configured to use the information about the remaining distance to the destination to recognize the necessary amount of electricity required until the vehicle reaches the destination, which information is recognized by the navigation device of the vehicle.
[0050] The battery status recognition device 150 may be configured to send information about the remaining power of the identified battery and the identified necessary power to the controller 160. The controller 160 may be configured to generate a charging plan when the vehicle travels to the destination using the following information: information about the power supply status of the power grid received from the power grid status recognition device 140 and information about the real-time electricity price according to the power supply status; information about the remaining power of the battery received from the battery status recognition device 150 and information about the necessary power.
[0051] Herein, the controller 160 may call the user DB 120, and may be configured to identify the user's charging mode, and generate a charging plan with reference to the user's charging mode, power supply status, real-time electricity price information, remaining battery power, and necessary power. Specifically, the controller 160 may be configured to generate a charging plan with the lowest charging cost. In other words, the controller 160 may be configured to generate a charging plan in the order of time intervals from low to high electricity prices in the time intervals in which the wireless charging road 1 is allowed to be used identified from the user DB 120, so that the charging amount is not greater than the necessary power.
[0052] For example, assuming that the current remaining power of the battery is x and the necessary power required to reach the destination is y, the target charge amount required to travel to the destination can be expressed as z=xy. In addition, assuming that the rechargeable time interval is t=[t1, t2, ..., tT] (where T is 24 hours), the rechargeable time interval identified from the user DB 120 on the corresponding day of the week can be expressed as t=[0, 1, 0, ..., tT].
[0053] In addition, assuming that the electricity price of each time interval is p=[p1, p2, ..., pT] (where T is 24 hours), the electricity price of each time interval identified by the power grid state identification device 140 can be expressed as p=[100, 150, 300, ..., pT]. Specifically, when the target charge amount is less than 0, the controller 160 can be configured to calculate the minimum charging cost by applying t and p to the following equation 2, and can be configured to generate a charging plan with the minimum charging cost based on the minimum charging cost.
[0054] Equation 2:
[0055]
[0056] In the above equation 2, P represents the minimum charging fee. The minimum charging fee P can be calculated by adding the electricity prices of the time intervals with lower electricity prices in the rechargeable time intervals. In the above equation 2, the charging plan T = [T1, T2, ..., TT] can be generated based on the time intervals for calculating the minimum charging fee.
[0057] At the same time, the controller 160 may be configured to generate a charging plan that excludes a time interval in which sufficient power cannot be supplied because the power supply state of the power grid is less than a reference level when generating the charging plan. As an example, the reference level for determining the power supply state may be determined based on, but not limited to, the amount of power that can be supplied. When generating a charging plan until the vehicle reaches the destination, the controller 160 may be configured to adjust the wireless charging of the vehicle based on the generated charging plan.
[0058] When wireless charging is required based on the charging plan, the controller 160 may allow the vehicle to move to the wireless charging road 1 to perform wireless charging. In addition, when wireless charging is not required based on the charging plan, the controller 160 may allow the vehicle to leave the wireless charging road 1 and drive. When a charging plan is generated, the controller 160 may be configured to request a navigation device to provide lane or route guidance according to the charging plan. Thus, according to the charging plan, the navigation device may guide the vehicle to move to another lane (e.g., a charging lane), or may guide the vehicle along a route. Herein, the navigation device may be provided in the vehicle, and may cooperate with the charging management device 100 for operation.
[0059] When wireless charging is performed based on the charging plan, if changed power supply information is received from the power grid state identification device 140, the controller 160 may be configured to regenerate the charging plan by reflecting the changed power supply information. As an example, when the power supply state of the power grid becomes less than a reference level, the controller 160 may be configured to regenerate the charging plan based on at least one of the remaining distance to the destination, the battery state, or the position of the road section where the power supply state is greater than or equal to the reference level.
[0060] At this time, the controller 160 may be configured to adjust the wireless charging based on the regenerated charging plan. Specifically, the controller 160 may be configured to request the navigation device to guide the vehicle along the lane or route according to the regenerated charging plan. When the vehicle arrives at the destination, the controller 160 may be configured to send information about the charging plan to the user DB management device 110. Specifically, the user DB management device 110 may be configured to update the user profile recorded in the user DB 120, that is, the usage mode of the wireless charging road 1, based on the charging plan.
[0061] Despite Figure 2 Although not shown in the figure, the charging management device 100 according to the exemplary embodiment of the present invention may further include an interface (not shown), which includes an input device for receiving a control instruction from a user, and an output device for outputting an operation state, an operation result, etc. of the charging management device 100. Herein, the input device may include a key, and may further include a soft key implemented on a display. In addition, the input device may further include a mouse, a joystick, a knob, a stylus, etc.
[0062] The output device may include a display, and may further include a voice output device. Specifically, a touch sensor such as a touch film, a touch sheet, or a touch pad may be provided in the display, the display may be used as a touch screen, and may be implemented in a form in which the input device and the output device are integrated with each other. The display may include at least one of a liquid crystal display (LCD), a thin film transistor-LCD (TFT-LCD), an organic light emitting diode (OLED) display, a flexible display, a field emission display (FED), or a three-dimensional (3D) display.
[0063] The charging management device 100 for a vehicle according to an exemplary embodiment of the present invention that performs the above-mentioned operation can be implemented in the form of an independent hardware device, and can be driven in the form of being included in another hardware device (e.g., a microprocessor) as at least one processor. The operation flow of the charging management device according to an exemplary embodiment of the present invention having the above-mentioned configuration will be described in detail.
[0064] Figures 4 to 6 1 is a flow chart showing the operation flow of a charging control method for a vehicle according to an exemplary embodiment of the present invention. Figure 4 When the vehicle starts to travel in step S110, in step S120, Figure 2 The charging management device 100 in the embodiment may be configured to call or access the user DB 120 constructed for the corresponding user, and may be configured to identify the user profile. Herein, the user profile may include Figure 1 The usage pattern of the wireless charging road 1, for example, information such as a usage time interval and an average usage time.
[0065] In addition, at step S130, the charging management device 100 may be configured to identify the power grid state, i.e., the power supply state and information about the electricity price for each time interval, from the power grid. In addition, at step S140, the charging management device 100 may be configured to identify the battery state of the vehicle. At step S140, the charging management device 100 may be configured to identify the remaining battery power of the vehicle, the necessary power to the destination, etc.
[0066] In step S150, the charging management device 100 may be configured to match the information identified in steps S120 to S140 (ie, the usage mode of the wireless charging road 1, the power grid status, and the battery status) to generate a charging plan. Figure 5 A description is given of the detailed operation flow of step S150.
[0067] Reference Figure 5In step S210, the charging management device 100 may be configured to match the usage time interval of the wireless charging road 1 identified in steps S120 to S140 with the usage time, the required power, and the electricity price of each time interval for each time interval. In step S220, the charging management device 100 may be configured to generate a charging plan with the lowest cost according to the order of time intervals with a low to high electricity price based on the matching results in step S210.
[0068] In this process, the charging management device 100 may be configured to generate a charging plan that does not include a time interval in which the power supply state is less than a reference level. In step S160, when the vehicle arrives at the destination, the charging management device 100 may be configured to adjust the battery charging based on the charging plan generated in step S150.
