[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] In this application, the terms "comprises", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.

[0058] As can be seen from the background technology, the existing charging method cannot automatically open or close the charging port cover, and the charging gun needs manual operation, which affects the automatic charging efficiency and the user experience.

[0059] Therefore, an embodiment of the present invention provides an automatic charging method, device and vehicle for electric vehicles. In this solution, after the current vehicle meets the charging conditions, the position of the target charging pile is calculated according to the position data and body data of the current vehicle. After the target charging pile meets the charging requirements, the charging port cover of the current vehicle is controlled to open, and the target charging pile controls the charging gun to charge the current vehicle, thereby realizing automatic charging, improving automatic charging efficiency, and enhancing the user experience.

[0060] First, the schematic diagram of the architecture of an electric vehicle automatic charging system to which the electric vehicle automatic charging method / device of the present application is applied is introduced. Figure 1As shown, the electric vehicle automatic charging system includes a HUT (Head Unit, intelligent cockpit module) host, camera, radar, CEM (central electronic control module), RLS (rain light sensor), PDCU (power chassis domain control unit), BMS (battery management system), TBOX (on-board wireless terminal controller), charging pile and server.

[0061] The HUT host is the infotainment terminal in the vehicle system, and users can select automatic charging configuration through the HUT host.

[0062] Among them, the configuration options are: ① The battery level must be below a certain level for automatic charging; ② Whether to automatically charge on rainy days.

[0063] It should be noted that by default, the battery will be automatically charged when the battery level is below 50%, and will not be automatically charged on rainy days.

[0064] Electric vehicles are equipped with charging ports and corresponding charging port covers, multiple cameras and multiple radars. The specific locations can be found in Figure 2 .

[0065] The camera is used to detect the surrounding conditions of the electric vehicle, including the direction of the charging station.

[0066] Radar is also used to detect the surrounding conditions of electric vehicles.

[0067] CEM is used to interact with the charging pile and perform corresponding automatic charging operations for electric vehicles.

[0068] RLS is used to detect weather conditions.

[0069] PDCU is used to detect the connection status of the charging gun.

[0070] BMS is used to calculate the time required to fully charge the electric vehicle after the electric vehicle is successfully charged, and send the time required to fully charge to TBOX.

[0071] TBOX is used to send the time required for full charging to the server.

[0072] The charging pile is used to interact with the CEM to perform corresponding automatic charging operations for the electric vehicle, which may include: when the electric vehicle meets the charging conditions and the charging pile meets the charging requirements, controlling the charging gun to charge the electric vehicle; when the power needs to be cut off during automatic charging without pulling out the gun, controlling the charging gun to stop charging the current vehicle and performing a charging timed wake-up confirmation; when the automatic charging is completed and the gun needs to be pulled out, controlling the charging gun to stop charging the current vehicle, and controlling the charging gun to disconnect from the charging port and retracting the charging gun.

[0073] The server is used to wake up the CEM at the scheduled time.

[0074] based on Figure 1 The process of realizing automatic charging of electric vehicles by the disclosed automatic charging system of electric vehicles is as follows:

[0075] After parking and turning off the engine, the four doors are closed. After receiving the key lock signal of the current vehicle, CEM receives the CAN message data of the current vehicle sent by the HUT host, and determines the configuration information of the current vehicle according to the CAN message data.

[0076] Among them, the CAN message data is obtained by setting the charging power information after the user triggers the configuration option on the HUT host, and is sent by the HUT host to the CEM.

[0077] The configuration information includes charging power information.

[0078] If the configuration information is not to automatically charge in case of rain, the CEM receives the first weather information sent by the RLS;

[0079] If the first weather information is non-rainy day, CEM receives the current vehicle power information sent by BMS, and compares the current vehicle power information with the preset charging power information. If the current vehicle power information matches the preset charging power information, it is determined that the current vehicle meets the charging conditions; if the current vehicle power information does not match the preset charging power information, it is determined that the current vehicle does not meet the charging conditions.

[0080] If the current vehicle meets the charging conditions, CEM obtains the current vehicle's position data and body data detected by the radar and camera.

[0081] The vehicle body data at least includes the position of the charging port cover.

[0082] CEM calculates the location of the charging pile based on the location data and vehicle body data. After determining that the location of the charging pile is within the radar detection range, it sends the charging instruction, location data, vehicle body data, and the location of the charging pile and charging port cover to the charging pile through TBOX wireless communication, allowing the charging pile to confirm whether the charging requirements are met.

[0083] When CEM receives feedback from the charging pile that the charging demand is not met, CEM controls the horn to make a sound and the turn signal to flash to remind the owner.

[0084] When the CEM receives the information that the charging demand is met from the charging pile, it controls the charging port cover of the current vehicle to open, and sends the information that the charging port cover has been opened to the charging pile while starting the timing, so that the charging pile controls the charging gun to charge the current vehicle based on the current vehicle's location data and body data, and the position of the charging pile and the charging port cover.

[0085] After 30 seconds, CEM receives data on whether PDCU is connected to the charging gun. If not, it notifies the charging pile of the abnormal charging, closes the charging port cover electrically, and reminds the user of the abnormal automatic charging through the APP.

[0086] After successful charging, the BMS calculates the charging time and informs the CEM of the time required for full charging. The CEM informs the TBOX of the time, and the TBOX informs the server to wake up the CEM at the scheduled time.

[0087] After the fully charged CEM is awakened, it receives RLS data to determine whether it is raining. If it is raining, it tells the charging pile to only cut off the power without pulling out the gun, and then wakes up for confirmation at a fixed time; if it is not raining, it tells the charging pile to pull out the gun after charging is completed.

[0088] The PDCU detects that the charging gun is disconnected and notifies the CEM, which then controls the charging port cover to close.

[0089] Based on an automatic charging system for electric vehicles provided by the above-mentioned embodiment of the present invention, after the current vehicle meets the charging conditions, the position of the charging pile is calculated according to the position data and body data of the current vehicle. After the charging pile meets the charging demand, the charging port cover of the current vehicle is controlled to open, and the charging pile controls the charging gun to charge the current vehicle, thereby realizing automatic charging, improving automatic charging efficiency, and enhancing the user experience.

[0090] Based on the electric vehicle automatic charging system shown above, Figure 3 , which is a flow chart of an automatic charging method for an electric vehicle provided by an embodiment of the present invention.

[0091] The automatic charging method for electric vehicles is applicable to a central electric control module CEM.

[0092] It should be noted that the central electronic control module CEM can be Figure 1 CEM in.

[0093] The electric vehicle automatic charging method mainly comprises the following steps:

[0094] Step S301: When a key lock signal of the current vehicle is received, execute step S302, otherwise, end the operation.

[0095] In the specific implementation of step S301, when the user drives the current vehicle to the charging area of ​​the charging pile in the parking lot, the current vehicle stops and turns off the engine, and the four doors are closed. The user can trigger the generation of a key lock signal by operating the car key. If the CEM receives the key lock signal of the current vehicle, step S302 is executed. If the CEM does not receive the key lock signal of the current vehicle, the operation is terminated directly.

[0096] Step S302: Determine whether the current vehicle meets the charging conditions. If so, execute step S303; if not, end the operation.

[0097] In the specific implementation of step S302, the CEM obtains the current power information of the vehicle from the BMS and the charging power information set by the user from the HUT host, and determines whether the current vehicle needs to be charged based on the two power information. If so, execute step S303; if not, directly end the operation.

[0098] Step S303: Acquire the current vehicle's position data and body data.

[0099] In step S303, the vehicle body data at least includes the position of the charging port cover.

[0100] In the specific implementation of step S303, when it is determined that the current vehicle meets the charging conditions, the radar and the camera detect the position data and the body data of the current vehicle, and the CEM obtains the position data and the body data of the current vehicle detected by the radar and the camera.

[0101] Step S304: Calculate the location of the target charging pile based on the location data and vehicle body data, and send the charging instruction, location data, vehicle body data, the location of the target charging pile and the charging port cover to the target charging pile through the on-board wireless terminal controller TBOX wireless communication, so that the target charging pile can confirm whether it meets the charging requirements.

[0102] In step S304, the charging requirements include but are not limited to whether the length of the charging gun is sufficient to be inserted into the charging port of the current vehicle, and the current vehicle is automatically charged.

[0103] In step S304, the charging instruction is an instruction that the current vehicle needs to be charged at the target charging pile.

[0104] In the specific implementation of step S304, Figure 2 For example, based on Figure 2 The position data and body data of the current vehicle are used to calculate the position of the target charging pile X. After determining that the target charging pile is near the current vehicle, that is, the target charging pile is within the radar detection range, the charging instruction, position data, body data, and the position of the target charging pile and the charging port cover are sent to the target charging pile through the on-board wireless terminal controller TBOX wireless communication, so that the target charging pile can confirm whether the charging demand is met.

[0105] Step S305: When the charging demand satisfying information fed back by the target charging pile is received, execute step S306.

[0106] In the process of implementing step S305, when the charging demand satisfaction information fed back by the target charging pile is received, it means that the target charging pile meets the charging demand, and step S306 is executed.

[0107] Preferably, in some embodiments, when receiving information from the target charging pile that charging demand is not met, the CEM controls the speaker to make a sound and controls the turn signal to flash to remind the owner.

[0108] Step S306: Control the charging port cover of the current vehicle to open, and send the information that the charging port cover has been opened to the target charging pile, so that the target charging pile controls the charging gun to charge the current vehicle based on the location data and body data of the current vehicle, and the location of the target charging pile and the charging port cover.

[0109] In the process of specifically implementing step S306, when it is determined that the CEM has received the information that the charging demand is met from the target charging pile, the CEM controls the charging port cover of the current vehicle to open, and sends the information that the charging port cover has been opened to the target charging pile, that is, the CEM electrically opens the charging port cover, and informs the target charging pile of the information that the charging port cover has been opened, so that the target charging pile determines the position of the charging port based on the position data and body data of the current vehicle, and the position of the target charging pile and the charging port cover, controls the charging gun to be inserted into the charging port of the current vehicle, and charges the current vehicle.

[0110] Based on an automatic charging method for electric vehicles provided by the above-mentioned embodiment of the present invention, after the current vehicle meets the charging conditions, the position of the target charging pile is calculated according to the position data and body data of the current vehicle. After the target charging pile meets the charging demand, the charging port cover of the current vehicle is controlled to open, and the target charging pile controls the charging gun to charge the current vehicle, thereby realizing automatic charging, improving automatic charging efficiency, and enhancing the user experience.

[0111] Based on the above-mentioned electric vehicle automatic charging method, the process of executing step S302 to determine whether the current vehicle meets the charging conditions can be as follows: Figure 4 As shown, including:

[0112] Step S401: receiving the CAN message data of the current vehicle sent by the HUT host.

[0113] In step S401, after the user triggers the configuration option on the HUT host, the CAN message data is set to obtain the charging power information and sent by the HUT host to the CEM.

[0114] It should be noted that the configuration options are: ① The battery level must be below a certain level for automatic charging; ② Whether to automatically charge on rainy days.

[0115] In the specific implementation process of step S401, after the user triggers the configuration option on the HUT host of the current vehicle, the charging power information is set. The HUT host sends the charging power information of the current vehicle set by the user to the CEM in the form of CAN message data, and the CEM receives the CAN message data of the current vehicle sent by the HUT host.

[0116] Step S402: Determine the configuration information of the current vehicle according to the CAN message data.

[0117] In step S402, the configuration information includes charging power information.

[0118] In the specific implementation of step S402 , the CEM parses the CAN message data to obtain the configuration information of the current vehicle, and determines the charging power information set by the user for the current vehicle from the configuration information.

[0119] Step S403: Determine whether the configuration information is that automatic charging is not performed when it rains. If so, execute step S404; if not, return to execute step S401.

[0120] Step S404: receiving the first weather information sent by the rain light sensor RLS.

[0121] It should be noted that the first weather information is used to confirm whether it is raining currently, that is, whether it is a rainy day currently.

[0122] In the specific implementation of step S404, when it is determined that the configuration information is not to automatically charge when it rains, the CEM receives the first weather information sent by the rain light sensor RLS.

[0123] Step S405: Determine whether the first weather information is a non-rainy day, if so, execute step S406, if not, end the operation.

[0124] In the process of implementing step S405, since the configuration information indicates that automatic charging is performed when it is not raining, if the first weather information is that it is not raining, it means that the current weather conditions allow automatic charging, and step S406 is executed. If the first weather information is that it is raining, it means that the current weather conditions do not allow automatic charging, and the operation is terminated directly.

[0125] Step S406: receiving the current vehicle power information sent by the battery management system BMS, and comparing the current vehicle power information with the charging power information.

[0126] In the specific implementation of step S406, when it is determined that the first weather information is not a rainy day, the CEM receives the current vehicle power information sent by the battery management system BMS, and compares the current vehicle power information with the charging power information in the configuration information to determine whether to perform automatic charging.

[0127] Step S407: Determine whether the current vehicle power information matches the charging power information. If so, execute step S408; if not, execute step S409.

[0128] Step S408: Determine whether the current vehicle meets charging conditions.

[0129] In the specific implementation of step S408, when it is determined that the power information of the current vehicle matches the charging power information, it is determined that the current vehicle meets the charging condition.

[0130] Step S409: Determine that the current vehicle does not meet charging conditions.

[0131] In the specific implementation of step S409, when it is determined that the power information of the current vehicle does not match the charging power information, it is determined that the current vehicle does not meet the charging condition.

[0132] Based on the above-mentioned embodiment of the present invention, an electric vehicle automatic charging system is provided. According to the current vehicle power information fed back by the BMS and the charging power information set by the user in the HUT host, it is determined whether the current vehicle meets the charging conditions, so as to confirm the subsequent automatic charging, improve the automatic charging efficiency, and enhance the user experience.

[0133] Based on the above-mentioned electric vehicle automatic charging method, the process of executing step S304 to calculate the position of the target charging pile according to the position data and the vehicle body data can be as follows: Figure 5 As shown, including:

[0134] Step S501: Establish a rectangular coordinate system with the current position of the charging port cover of the vehicle as the coordinate origin.

[0135] In the specific implementation of step S501, the charging port cover of the current vehicle is calibrated to obtain the position of the charging port cover, and a rectangular coordinate system is established with the position of the charging port cover of the current vehicle as the coordinate origin.

[0136] Step S502: Based on a rectangular coordinate system, determine the rear camera position, radar position, angle between the camera and the target charging pile, and distance between the radar and the target charging pile in the position data and the vehicle body data.

[0137] In the process of implementing step S502, based on the rectangular coordinate system, the position of the rear camera and the radar are determined in the position data and the vehicle body data. Since the camera can detect the direction of the target charging pile, the angle between the camera and the target charging pile can be determined according to the position of the charging port cover, the position of the rear camera and the radar. Since the radar can detect the distance between it and the target charging pile, it can be determined that the distance between the radar and the target charging pile is known.

[0138] Step S503: Calculate the position of the charging pile according to a preset calculation formula, the position of the charging port cover, the position of the rear camera, the position of the radar, the angle between the camera and the target charging pile, and the distance between the radar and the target charging pile to obtain the position of the charging pile.

[0139] In order to better understand the above description, Figure 2 For example, assuming that the charging port cover is on the left rear of the vehicle and the charging pile is behind the vehicle, a rectangular coordinate system is established with the charging port cover as the coordinate origin. The black circle in the figure is the camera and the gray circle is the radar. Among them, B is the charging port cover, A is the camera, C is the radar, and X is the target charging pile. Then A(c, d), B(0, 0), C(e, f) are known quantities, and X(x, y) is an unknown quantity.

[0140] Since the camera can detect the direction of the charging pile but not the distance of the charging pile, the angle a is a known quantity and the following formula can be listed:

[0141] tan(a)=(cx) / (dy), (1),

[0142] Since the distance that the radar can detect CX (the distance between the radar and the target charging pile) is m, the following formula can be listed:

[0143] (xe) 2 +(yf) 2 =m 2 , (2),

[0144] By transforming formula (1), we can get x, that is, x=c-(dy)*tan(a). Substituting x=c-(dy)*tan(a) into formula (2), we can calculate y.

[0145] Among them, y has two values, one positive and one negative. Since y is negative, the positive value is discarded.

[0146] After the coordinates X(x, y) are calculated, the distance BX (the distance between the charging port cover and the target charging pile) can be calculated, and the direction angle b satisfies the formula tan(b)=x / (-y), so the position of the target charging pile can be determined.

[0147] Based on an automatic charging method for electric vehicles provided by the above-mentioned embodiment of the present invention, after the current vehicle meets the charging conditions, the position of the target charging pile is calculated according to the position data and body data of the current vehicle, so that after the target charging pile meets the charging demand, the charging port cover of the current vehicle is controlled to open, and the target charging pile controls the charging gun to charge the current vehicle, thereby realizing automatic charging, improving automatic charging efficiency, and enhancing the user experience.

[0148] Based on the above-mentioned electric vehicle automatic charging method, after executing step S306 to send the charging port cover opening information to the target charging pile, Figure 6 As shown, it also includes:

[0149] Step S601: Start timing.

[0150] In the specific implementation of step S601, the CEM electrically opens the charging port cover, informs the target charging pile of the opening of the charging port cover, and performs timing at the same time, and then determines whether the target charging pile is successfully charged based on the obtained timing time.

[0151] Step S602: When the timing time reaches the preset time, execute step S603, otherwise, return to execute step S601.

[0152] In step S602, the specific value of the preset time may be determined according to the actual situation of automatic charging of the electric vehicle, and this application does not limit it and is within the protection scope of this application.

[0153] Preferably, in some embodiments, the preset time is 30s.

[0154] In the process of implementing step S602, the timing time is compared with the preset time. If the timing time is greater than or equal to the preset time, it means that the timing time has reached the preset time, and step S603 is executed. If the timing time is less than the preset time, it means that the timing time has not reached the preset time, then the timing continues, that is, returning to execute step S601.

[0155] Step S603: Receive charging gun connection status data sent by the power chassis domain control unit PDCU.

[0156] In step S603 , the charging gun connection status data is whether the charging gun is not connected or whether the charging gun is connected.

[0157] In the specific implementation of step S603, when it is determined that the timing time reaches the preset time, the charging gun connection status data sent by the power chassis domain control unit PDCU is received.

[0158] Step S604: Determine whether the charging gun connection status data indicates that the charging gun is not connected. If so, execute step S605; if not, execute step S608.

[0159] Step S605: Send the abnormal charging information of the charging pile to the target charging pile, so that the target charging pile controls the charging gun to charge the current vehicle based on the position data and body data of the current vehicle, and the position of the target charging pile and the charging port cover.

[0160] In the process of implementing step S605, when it is determined that the charging gun connection status data is not connected to the charging gun, charging pile charging abnormality information is generated, and the charging pile charging abnormality information is sent to the target charging pile, so that the target charging pile controls the charging gun to charge the current vehicle based on the current vehicle position data and body data, and the position of the target charging pile and the charging port cover.

[0161] Step S606: Control the charging port cover of the current vehicle to close.

[0162] In the specific implementation of step S606, if the charging gun is not connected, after the target charging pile is informed of the charging abnormality, the charging port cover is electrically controlled to close.

[0163] Step S607: Based on the application APP associated with the CEM, an automatic charging abnormality reminder message is sent to the APP, and the APP responds to the automatic charging abnormality reminder message.

[0164] In the specific implementation of step S607, an application APP associated with the CEM is determined, and based on the APP, an automatic charging abnormality reminder message is sent to the APP, and the APP responds to the automatic charging abnormality reminder message to remind the user of the automatic charging abnormality.

[0165] Step S608: When receiving the successful charging information fed back by the target charging pile, execute step S609, otherwise, continue to execute step S608.

[0166] In the process of implementing step S608, when the successful charging information fed back by the target charging pile is received, step S609 is executed. Otherwise, it means that although the charging gun has been connected, the charging information fed back by the target charging gun has not been received, and step S608 is continued.

[0167] Step S609: receiving the current vehicle full-charge time sent by the battery management system BMS, and sending the full-charge time to TBOX, so that TBOX sends the full-charge time to the server, so that the server wakes up the CEM at the scheduled time.

[0168] In the process of implementing step S609, after the target charging gun controls the charging gun to successfully charge the current vehicle, the target charging pile feeds back the successful charging information to the CEM. At the same time, the BMS calculates the charging time for the current vehicle and sends the time required for full charging of the current vehicle to the CEM. When the CEM determines that it has received the successful charging information fed back by the target charging pile, the CEM receives the time required for full charging of the current vehicle sent by the battery management system BMS, and sends the time required for full charging to the TBOX, so that the TBOX sends the time required for full charging to the server, so that the server wakes up the CEM at the scheduled time.

[0169] That is, after receiving the time required for full charging of the current vehicle, CEM informs TBOX of the time required for full charging of the current vehicle, and TBOX informs the server to wake up CEM at the scheduled time.

[0170] It should be noted that by calculating the current charging time of the vehicle through the BMS and informing the server to schedule a wake-up, power consumption can be reduced. The main reason is that a lot of heat is generated during charging, and if the controller does not perform low power consumption, the heat dissipation demand will increase.

[0171] Based on an automatic charging method for an electric vehicle provided by the above-mentioned embodiment of the present invention, the CEM sends the information that the charging port cover has been opened to the target charging pile, and after the timing time reaches the preset time, it confirms whether the charging gun is connected according to the received charging gun connection status data to determine whether to perform automatic charging abnormality reminder. After successful charging, the time required for full charging of the current vehicle is sent to the server, so that the server wakes up the CEM at the scheduled time, so as to facilitate the subsequent confirmation of whether to automatically unplug the charging gun when the current vehicle is fully charged, thereby improving the automatic charging efficiency and enhancing the user experience.

[0172] Based on the above-mentioned electric vehicle automatic charging method, after executing step S607 to enable the server to wake up the CEM at the scheduled time, Figure 7 As shown, it also includes:

[0173] Step S701: Determine whether the current vehicle is fully charged and whether the CEM is awakened. If so, execute step S702; if not, end the operation.

[0174] Step S702: Receive the second weather information sent by the RLS.

[0175] It should be noted that the second weather information is used to confirm whether it is raining currently, that is, whether it is a rainy day currently.

[0176] In the specific implementation of step S702 , when determining whether the current vehicle is fully charged and whether the CEM is awakened, the CEM receives the second weather information sent by the RLS.

[0177] Step S703: Determine whether the second weather information is rainy, if so, execute step S704, if not, execute step S705.

[0178] In the process of implementing step S703, since the current vehicle is fully charged, if the second weather information is rainy, it means that if the charging gun is unplugged under the current weather conditions, the charging gun is prone to water ingress, causing the charging gun to malfunction, then execute step S704; if the first weather information is not rainy, it means that the current weather conditions are convenient for unplugging the charging gun, then execute step S705.

[0179] Step S704: Send the power-off and gun-unplugging information to the target charging pile, so that the target charging pile controls the charging gun to stop charging the current vehicle and performs charging timed wake-up confirmation.

[0180] In the process of implementing step S704, when it is determined that the second weather information is a rainy day, power-off but not gun unplugging information is generated and sent to the target charging pile, so that the target charging pile controls the charging gun to stop charging the current vehicle and performs a charging timed wake-up confirmation, so that after the weather clears up, the target charging pile controls the charging gun to disconnect from the charging port and retract the charging gun.

[0181] Step S705: Send the charging completion and gun removal information to the target charging pile, so that the target charging pile controls the charging gun to stop charging the current vehicle, controls the charging gun to disconnect from the charging port, and retracts the charging gun.

[0182] In the process of implementing step S705, when it is determined that the second weather information is not a rainy day, information that the charging gun needs to be unplugged is generated and sent to the target charging pile, so that the target charging pile controls the charging gun to stop charging the current vehicle, and controls the charging gun to disconnect from the charging port and retract the charging gun. That is to say, the target charging pile controls the charging gun to be unplugged from the charging port of the current vehicle and retracts the charging gun to the target charging pile.

[0183] Step S706: When the charging gun disconnection information sent by the PDCU is received, execute step S707; otherwise, execute step S706.

[0184] In the process of implementing step S706, the PDCU detects whether the charging gun has been disconnected from the charging port. If it is detected that the charging gun has been disconnected from the charging port, the charging gun disconnection information is generated and sent to the CEM. When the CEM receives the charging gun disconnection information sent by the PDCU, step S707 is executed; otherwise, step S706 is continued.

[0185] Step S707: Control the charging port cover of the current vehicle to close.

[0186] In the specific implementation of step S707, when it is determined that the charging gun has been disconnected information sent by the PDCU is received, the CEM controls the charging port cover of the current vehicle to be closed.

[0187] Based on the above-mentioned embodiment of the present invention, an automatic charging method for an electric vehicle is provided. When the vehicle is fully charged and the CEM is awakened, it is determined whether the charging gun is unplugged according to the current weather conditions, thereby improving the automatic charging efficiency and enhancing the user experience.
