[0002] At present, domestic electric vehicles are developing rapidly, and new energy vehicles are gradually going abroad. Due to the differences in domestic and foreign charging equipment and reference standards, domestic products cannot be directly applied overseas. It is necessary to configure EVCC (Electric Vehicle Communication Controller) to convert domestic and foreign charging protocols and participate in the control of electronic locks.

[0003] In the relevant technology, due to the differences between charging piles in the European Union, some charging piles need to swipe a card before they can output the CP (Control Pilot, control signal loop) signal, and when the CP signal cannot wake up the EVCC, the gun plug signal cannot be detected, which may cause the vehicle to drive with the gun. Some charging guns have poor contact with the vehicle-end socket, which will result in the gun plug signal being detected only during the gun plugging process. After the gun is plugged in, due to the weight and torque of the wiring harness, the PP (Proximity Pilot, proximity guidance) / CP signal cannot be detected, resulting in the inability to enter the charging process.

[0012] According to some embodiments of the present invention, charging of a vehicle is controlled based on status information of a CP signal, including: when it is determined based on the status information that the duty cycle of the CP signal is within a first preset range, DC charging of the vehicle is performed; when it is determined based on the status information that the duty cycle of the CP signal is within a second preset range, AC charging of the vehicle is performed, wherein the duty cycle value of the first preset range is smaller than the duty cycle value of the second preset range.

[0013] According to some embodiments of the present invention, the above method also includes: when it is determined based on the status information that the duty cycle of the CP signal is not within the first preset range and the second preset range, obtaining the first cumulative time duration that the CP signal continues to be in the current duty cycle; when the first cumulative time duration is greater than the first preset time duration, controlling the charging communication controller to enter a sleep state, and controlling the electronic lock to turn off to disconnect the vehicle from the charging gun.

[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The following describes a vehicle charging control method, a vehicle charging control device, a computer-readable storage medium, and a vehicle according to embodiments of the present invention with reference to the accompanying drawings.

[0031] Figure 1 The figure is a flow chart of a vehicle charging control method according to some embodiments of the present invention.

[0032] like Figure 1 As shown, the vehicle charging control method of the embodiment of the present invention may include the following steps:

[0033] S1, when it is determined that the vehicle generates a charging wake-up instruction, waking up the charging communication controller of the vehicle according to the charging wake-up instruction.

[0034] Specifically, when the charging gun is inserted into the vehicle's charging socket, the charging gun will start charging the vehicle in the subsequent working process. During the process of the charging gun being inserted into the charging socket, the charger will detect the resistance value of the PP or the CP signal. When the resistance value of the PP or the CP signal changes, a charging wake-up instruction is generated according to the change in the resistance value of the PP or the CP signal, and then the vehicle's charging communication controller is woken up according to the charging wake-up instruction.

[0035] S2, after the charging communication controller is awakened, the vehicle is prohibited from driving, and the electronic lock is controlled to close so that the vehicle is connected to the charging gun.

[0036] Specifically, after the vehicle's charging communication controller is awakened, the vehicle's charging communication controller sends an instruction to the vehicle control unit (VCU) to prohibit the vehicle from driving, and sends a charging connection signal to the vehicle's dashboard. After the vehicle controller receives the instruction sent by the vehicle's charging communication controller and the vehicle's dashboard receives the charging connection signal, the vehicle controller prohibits the vehicle from driving, and the vehicle's dashboard turns on the instrument charging connection indicator light. The vehicle's charging communication controller controls the electronic lock to close, so that the vehicle is connected to the charging gun, ensuring that the vehicle-end charging socket is in close contact with the charging gun and the vehicle will not drive with the gun.

[0037] S3, detecting the CP signal of the vehicle.

[0038] S4, controlling the charging of the vehicle according to the status information of the CP signal.

[0039] Specifically, after the vehicle is connected to the charging gun, the CP signal of the vehicle will be detected. When the CP signal of the vehicle is detected, the vehicle will be charged according to the status information of the CP signal. For example, when the duty cycle of the CP signal is in a small range, DC charging (i.e., fast charging) will be performed to speed up the charging efficiency; when the duty cycle of the CP signal is in a large range, AC charging (i.e., slow charging) will be performed to reduce the impact on the grid load. Therefore, the PP or CP signal can be used to immediately wake up the EVCC and control the electronic lock to lock when the gun is plugged in, ensuring that the vehicle-side charging socket is in close contact with the charging gun, and at the same time sending a driving prohibition instruction to the vehicle controller to ensure that the vehicle will not drive with the gun, improving the convenience of user use and increasing the safety of car charging.

[0040] The vehicle charging control method according to the embodiment of the present invention is described in detail below.

[0041] In some embodiments of the present invention, the above method also includes: detecting the PP resistance change value and the CP signal change value of the vehicle; when it is determined that the PP resistance has changed according to the PP resistance change value, or when it is determined that the CP signal has changed according to the CP signal change value, determining that the vehicle generates a charging wake-up instruction.

[0042] Specifically, refer to Figure 2 , which is a block diagram of a charging-related electrical topology according to some embodiments of the present invention. After the vehicle is plugged into the charging gun, the PP line between the on-board charger and the vehicle charging port can be disconnected, and then the PP resistance value between the PP line (on the connector near the vehicle charging port side) and the vehicle chassis ground can be measured. Then, the CP signal can be detected by monitoring the interaction between the electric vehicle and the electric vehicle power supply equipment (charging pile). The charger can also be used to detect the PP resistance value or CP signal. After detecting the PP resistance change value and the CP signal change value of the vehicle, when the PP resistance change value is zero, it indicates that the PP resistance has not changed. When the PP resistance change value is not zero, it indicates that the PP resistance has changed. When the PP resistance changes, the vehicle can generate a charging wake-up instruction to wake up the charging communication controller of the vehicle.

[0043] Alternatively, when the CP signal change value is zero, it indicates that the CP signal has not changed; when the CP signal change value is not zero, it indicates that the CP signal has changed; when the CP signal changes, the vehicle may generate a charging wake-up instruction to wake up the vehicle's charging communication controller.

[0044] In some embodiments of the present invention, charging control of a vehicle is performed according to the state information of a CP signal, including: when it is determined according to the state information that the duty cycle of the CP signal is within a first preset range, DC charging of the vehicle is performed; when it is determined according to the state information that the duty cycle of the CP signal is within a second preset range, AC charging of the vehicle is performed, wherein the duty cycle value of the first preset range is less than the duty cycle value of the second preset range. The first preset range and the second preset range can be calibrated according to actual conditions.

[0045] In some embodiments of the present invention, the vehicle also includes a battery management system, and DC charging of the vehicle includes: sending a first confirmation message to the battery management system so that the battery management system controls the vehicle to perform DC charging after receiving the first confirmation message.

[0046] Furthermore, in some embodiments of the present invention, the vehicle also includes an on-board charger, and AC charging the vehicle includes: sending a second confirmation message to the on-board charger, so that the on-board charger controls the vehicle to perform AC charging after receiving the second confirmation message.

[0047] Specifically, after waking up the charging communication controller of the vehicle, it is determined whether the CP signal of the vehicle is detected. When the CP signal of the vehicle is detected, the state information of the CP signal is determined to control the charging of the vehicle. When it is determined according to the state information that the duty cycle of the CP signal is in a first preset range (such as 3%-7%), continue to refer to Figure 2 , the vehicle's charging communication controller (EVCC) sends a first confirmation message (CC2 (Constant Voltage, constant voltage charging) signal) to the battery management system (BMS). After the battery management system receives the confirmation message sent by the vehicle's charging communication controller, the battery management system starts DC charging of the vehicle to improve charging efficiency. Among them, the CC2 signal means that during the charging process, if the non-vehicle charging device does not receive the charging level requirement message periodically sent by the battery management system within 100ms, the non-vehicle charging device also responds to the function of shutting down the DC power output.

[0048] When it is determined according to the state information that the duty cycle of the CP signal is in the second preset range (8%-97%), continue to refer to Figure 2, the vehicle's charging communication controller sends a second confirmation message (CC (Control Current, constant current charging) signal) to the on-board charger (OBC). After the on-board charger receives the confirmation message sent by the vehicle's charging communication controller, the vehicle's charging communication controller starts to charge the vehicle with AC to reduce the impact on the grid load. Among them, the CC signal refers to a signal sent by the charging pile to the electric vehicle, which is used to inform the electric vehicle of the charging pile's support capabilities and charging methods. The CC signal is determined by the voltage output by the charging pile. When the CC signal voltage is 12V, it means that the pile supports reduced power charging. When the CC signal voltage is 9V, it means that the pile supports communication charging to charge the vehicle with AC.

[0049] In some embodiments of the present invention, the above method further includes: when it is determined according to the state information that the duty cycle of the CP signal is not within the first preset range and the second preset range, obtaining the first cumulative duration of the CP signal being in the current duty cycle; when the first cumulative duration is greater than the first preset duration, controlling the charging communication controller to enter a dormant state, and controlling the electronic lock to turn off so that the vehicle is disconnected from the charging gun. The first preset duration can be calibrated according to actual conditions.

[0050] Specifically, when it is determined according to the status information that the duty cycle of the CP signal is not within the first preset range and the second preset range (such as less than 3% and greater than 97%), it means that the charging pile cannot charge the vehicle. At this time, the first cumulative duration of the CP signal being in the current duty cycle is obtained, and it is determined whether the first cumulative duration of the current duty cycle is greater than the first preset duration (such as 5 minutes). When the first cumulative duration is greater than the first preset duration, it means that the charging gun has been unable to charge the vehicle. In order to reduce energy consumption, the charging communication controller is controlled to enter a dormant state, and the electronic lock is controlled to be turned off to disconnect the vehicle from the charging gun. When the first cumulative duration is less than or equal to the first preset duration, it is continued to be determined whether the CP signal is detected.

[0051] In some embodiments of the present invention, the method further includes: starting timing when the CP signal of the vehicle is not detected to obtain a second cumulative duration of continuous failure to detect the CP signal; if the second cumulative duration is greater than a second preset duration, controlling the charging communication controller to enter a dormant state, and controlling the electronic lock to turn off so that the vehicle is disconnected from the charging gun. The second preset duration can be calibrated according to actual conditions.

[0052] Specifically, when the CP signal of the vehicle is not detected, the timer can be used to start timing, determine the time when the CP signal of the vehicle is not detected, and record it as the second cumulative duration, and then determine whether the second cumulative duration is greater than the second preset duration (such as 5 minutes). When the second cumulative duration is greater than the second preset duration, it means that the CP signal of the vehicle has not been detected for a long time. In order to reduce energy consumption, the charging communication controller is controlled to enter a dormant state at this time, and the electronic lock is controlled to be turned off to disconnect the vehicle from the charging gun. When the second cumulative duration is less than or equal to the second preset duration, it means that the CP signal of the vehicle has not been detected for a short time, and it is continued to determine whether the CP signal is detected.

[0053] As a specific example, Figure 3 As shown, the vehicle charging control method of the present invention may include the following steps:

[0054] S101, the vehicle is controllably connected to the charging gun.

[0055] S102, detecting the PP resistance change value and the CP signal change value of the vehicle.

[0056] S103, when it is determined that the PP resistance has changed according to the PP resistance change value, or when it is determined that the CP signal has changed according to the CP signal change value, determining that the vehicle has generated a charging wake-up instruction.

[0057] S104, determine whether the CP signal of the vehicle is detected. If yes, execute step S105; if not, execute step S113.

[0058] S105, judging whether it is established that the duty cycle of the CP signal is within a first preset range according to the state information of the CP signal. If yes, executing step S106; if not, executing step S107.

[0059] S106, DC charging the vehicle.

[0060] S107, judging whether it is established that the duty cycle of the CP signal is within a second preset range according to the state information of the CP signal. If yes, executing step S108; if not, executing step S109.

[0061] S108, AC charging the vehicle.

[0062] S109, judging whether it is true that the duty cycle of the CP signal is not within the first preset range and the second preset range according to the state information. If yes, executing step S110; if not, returning to step S104.

[0063] S110, obtaining a first accumulated time duration during which the CP signal is continuously at the current duty cycle.

[0064] S111, determine whether the first accumulated duration is greater than the first preset duration. If yes, execute step S112; if not, return to step S104.

[0065] S112, controlling the charging communication controller to enter a dormant state, and controlling the electronic lock to turn off to disconnect the vehicle from the charging gun.

[0066] S113, start timing to obtain a second accumulated time duration during which the CP signal is not detected.

[0067] S114, determining whether the second accumulated duration is greater than the second preset duration. If yes, return to step S112; if no, return to step S104.

[0068] In summary, according to the vehicle charging control method of the embodiment of the present invention, when it is determined that the vehicle generates a charging wake-up instruction, the charging communication controller of the vehicle is awakened according to the charging wake-up instruction; after the charging communication controller is awakened, the vehicle is prohibited from driving, and the electronic lock is controlled to close so that the vehicle is connected to the charging gun; the CP signal of the vehicle is detected; and the charging of the vehicle is controlled according to the status information of the CP signal. Therefore, the method can immediately wake up the EVCC and control the locking of the electronic lock by using the PP or CP signal when the gun is plugged in, ensuring that the vehicle-side charging socket is in close contact with the charging gun, and at the same time sending a driving prohibition instruction to the vehicle controller to ensure that the vehicle will not drive with the gun, thereby improving the convenience of user use and increasing the safety of car charging.

[0069] Based on the vehicle charging control method proposed in the aforementioned embodiment of the present invention, the embodiment of the present invention further proposes a computer-readable storage medium, which includes a vehicle charging control program. When the charging control program is executed by a processor, the aforementioned vehicle charging control method is implemented.

[0070] According to the computer-readable storage medium of an embodiment of the present invention, the above-mentioned vehicle charging control method is executed by a processor. By using the PP or CP signal when the charging gun is inserted, the EVCC can be immediately awakened and the electronic lock can be controlled to lock, ensuring that the vehicle-end charging socket is in close contact with the charging gun. At the same time, a driving-not-allowed instruction is sent to the vehicle controller to ensure that the vehicle will not be driven with the gun, thereby improving the convenience of user use and increasing the safety of car charging.

[0071] Figure 4 4 is a block diagram of a charging control device for a vehicle according to an embodiment of the present invention.

[0072] Specifically, Figure 4 As shown, the vehicle charging control device 100 according to the embodiment of the present invention may include: a wake-up module 110 , a control module 120 and a detection module 130 .

[0073] Among them, the awakening module 110 is used to wake up the charging communication controller of the vehicle according to the charging awakening instruction when it is determined that the vehicle generates a charging awakening instruction. The control module 120 is used to prohibit the vehicle from driving after the charging communication controller is awakened, and control the electronic lock to close so that the vehicle is connected to the charging gun. The detection module 130 is used to detect the CP signal of the vehicle. The control module 120 is also used to control the charging of the vehicle according to the status information of the CP signal.

[0074] In some embodiments of the present invention, the detection module 130 is also used to detect the PP resistance change value and the CP signal change value of the vehicle; when it is determined that the PP resistance has changed according to the PP resistance change value, or when it is determined that the CP signal has changed according to the CP signal change value, it is determined that the vehicle has generated a charging wake-up instruction.

[0075] In some embodiments of the present invention, the control module 120 controls the charging of the vehicle according to the status information of the CP signal, specifically for: when it is determined according to the status information that the duty cycle of the CP signal is within a first preset range, the vehicle is DC charged; when it is determined according to the status information that the duty cycle of the CP signal is within a second preset range, the vehicle is AC charged, wherein the duty cycle value of the first preset range is less than the duty cycle value of the second preset range.

[0076] In some embodiments of the present invention, the control module 120 is also used to obtain a first cumulative duration in which the CP signal is continuously in the current duty cycle when it is determined based on status information that the duty cycle of the CP signal is not within a first preset range and a second preset range; when the first cumulative duration is greater than the first preset duration, control the charging communication controller to enter a sleep state, and control the electronic lock to turn off to disconnect the vehicle from the charging gun.

[0077] In some embodiments of the present invention, the vehicle also includes a battery management system, and the control module 120 performs DC charging on the vehicle, specifically for: sending a first confirmation message to the battery management system so that the battery management system controls the vehicle to perform DC charging after receiving the first confirmation message.

[0078] In some embodiments of the present invention, the vehicle further includes an on-board charger, and the control module 120 performs AC charging on the vehicle, specifically for: sending a second confirmation message to the on-board charger, so that the on-board charger controls the vehicle to perform AC charging after receiving the second confirmation message.

[0079] In some embodiments of the present invention, the detection module 130 is also used to start timing when the CP signal of the vehicle is not detected, so as to obtain a second cumulative time duration for which the CP signal has not been detected continuously; if the second cumulative time duration is greater than the second preset time duration, the control module 120 controls the charging communication controller to enter a sleep state, and controls the electronic lock to turn off to disconnect the vehicle from the charging gun.

[0080] It should be noted that for other specific implementations of the vehicle charging control device proposed in the embodiment of the present invention, reference can be made to the specific implementations of the vehicle charging control method in the aforementioned embodiment of the present invention, and will not be repeated here to reduce redundancy.

[0081] In summary, according to the vehicle charging control device of the embodiment of the present invention, when the wake-up module determines that the vehicle generates a charging wake-up instruction, it wakes up the vehicle's charging communication controller according to the charging wake-up instruction. After the charging communication controller is awakened, the control module prohibits the vehicle from driving and controls the electronic lock to close so that the vehicle is connected to the charging gun. The detection module detects the CP signal of the vehicle, and the control module also controls the vehicle's charging according to the status information of the CP signal. Therefore, the device can immediately wake up the EVCC and control the electronic lock to lock by using the PP or CP signal when the gun is plugged in, ensuring that the vehicle-side charging socket is in close contact with the charging gun, and at the same time sending a driving prohibition instruction to the vehicle controller to ensure that the vehicle will not drive with the gun, thereby improving the convenience of user use and increasing the safety of car charging.
