Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric vehicles, and in particular to an electric vehicle charging protection method and device, an electronic device and a storage medium. BACKGROUND

[0002] In recent years, with the continuous advocacy and popularization of green transportation in society, various green transportation tools have gradually emerged and become more and more popular in daily use. For example, electric vehicles. Electric vehicles not only meet the national energy-saving and environmental protection trend, but also greatly facilitate short-distance transportation. However, since electric vehicles are electrically driven, and in the case of charging peak or lack of charging facilities, the vehicle owner will often intentionally pull out the plug of the electric vehicle being charged and plug it into the charger plug of his own electric vehicle for charging. Therefore, how to effectively protect the electric vehicle being charged is particularly important.

[0003] In related technologies, the electric vehicle during charging is usually monitored by a cloud platform connected through a charging pile or a charging station. If it is detected that the charger plug of the electric vehicle that is not fully charged is pulled out, the negative impact and probability of the charger plug being pulled out are reduced by the following methods: a method of pushing a reminder information to the charging user terminal in real time, a method of warning others not to arbitrarily pull out the charger plug during charging by pre-pasting a notice information beside the charging pile or the charging station, and a method of criticizing and educating the user who arbitrarily pulls out the charger plug by a manager or a police through manual search and monitoring.

[0004] However, since the existing scheme focuses on reminding the phenomenon that the charger plug of the electric vehicle during charging is pulled out, it cannot timely and effectively determine whether the electric vehicle being charged is the one that is pulled out or the one that is newly inserted, thereby resulting in low efficiency and poor practicality of electric vehicle charging protection.

[0052] Referring to Figure 1 The flowchart of the electric vehicle charging protection method provided by the embodiments of the present application is shown in FIG. 1. The electric vehicle charging protection method comprises the following steps: Figure 1

[0053] In step 110, based on the detected first plug-pulled identifier of the first charger of the first electric vehicle, the first physical feature information of the user and the first appearance feature information of the first electric vehicle are obtained.

[0054] The first plug-pulled identifier of the first charger can be generated in the case that the user pulls out the first charger. The first physical feature information can include but is not limited to the facial feature information, helmet color, body feature information, hairstyle feature information, clothing feature information and gender feature information of the user, etc. The facial feature information of the user can include but is not limited to the iris feature, nose wing feature, mouth corner feature and facial contour size of the user, etc. The body feature information of the user can include but is not limited to the height information and fat information of the user. The hairstyle feature information of the user can include but is not limited to one of short hair, long hair, curly hair and flat head of the user. The clothing feature information of the user can include but is not limited to the clothing color and clothing style of the user, etc. The gender feature information of the user represents that the user is male or female. The first appearance feature information of the user can include but is not limited to the license plate number, color and brand of the first electric vehicle, etc. Herein, no specific limitation is made.

[0055] ​Specifically, based on the detected unplug identification of the first electric vehicle's first charger plug, the cloud platform can instruct the charging pile or charging station accessing the first charger plug to first capture image information of the user unplugging the charger and then extract appearance feature information, thereby obtaining the first appearance feature information of the user unplugging the charger and the first appearance feature information of the first electric vehicle.

[0056] Step 120: Based on the detected insertion identification of the second charger plug into the first charger plug's corresponding socket, obtain the second appearance feature information of the user plugging in the charger and the second appearance feature information of the second electric vehicle corresponding to the second charger plug.

[0057] The insertion identification of the second charger plug can be generated when the user plugging in the charger inserts the second charger plug into the first charger plug's corresponding socket. The second appearance feature information can include, but is not limited to, the user plugging in the charger's facial feature information, helmet color, body shape feature information, hairstyle feature information, clothing feature information, and gender feature information. The user plugging in the charger's facial feature information can include, but is not limited to, the user plugging in the charger's eye iris feature, nose wing feature, mouth corner feature, and facial contour size. The user plugging in the charger's body shape feature information can include, but is not limited to, the user plugging in the charger's height information and fatness information. The user plugging in the charger's hairstyle feature information can include, but is not limited to, the user plugging in the charger's short hair, long hair, curly hair, or flat head. The user plugging in the charger's clothing feature information can include, but is not limited to, the user plugging in the charger's clothing color and clothing style. The user plugging in the charger's gender feature information indicates that the user plugging in the charger is male or female. The second appearance feature information of the user plugging in the charger can include, but is not limited to, the second electric vehicle's license plate number, color, and brand, etc. Here, no specific limitation is made.

[0058] Specifically, based on the detected insertion identification of the second charger plug into the first charger plug's corresponding socket, the cloud platform can also instruct the charging pile or charging station to first capture image information of the user plugging in the charger and then extract appearance feature information, thereby obtaining the second appearance feature information of the user plugging in the charger and the second appearance feature information of the second electric vehicle.

[0059] Step 130: Determine the target electric vehicle identification matching the first appearance feature information, the first appearance feature information, the second appearance feature information, and the second appearance feature information. The target electric vehicle identification represents the first electric vehicle or the second electric vehicle.

[0060] Specifically, the cloud platform analyzes the first physical feature information of the unplugging user, the first appearance feature information of the first electric vehicle, the second physical feature information of the plugging user and the second appearance feature information of the second electric vehicle corresponding to the second charger plug, to determine the relationship between the unplugging user, the plugging user and the first user corresponding to the first electric vehicle, and the relationship between the first electric vehicle and the second electric vehicle, and determine whether the current charging pile continues to charge the first electric vehicle or inserts the second electric vehicle, that is, determine the target electric vehicle identifier.

[0061] Step 140, generating a charging instruction based on the target electric vehicle identifier, the charging instruction being used to instruct the charging pile corresponding to the socket to charge the first electric vehicle or the second electric vehicle.

[0062] Specifically, when the charging instruction generated by the cloud platform based on the target electric vehicle identifier is to continue to charge the first electric vehicle, the charging order of the first electric vehicle can be resumed in the case that the reinserted charger plug is determined to be the first charger plug of the first electric vehicle, so that the charging pile continues to charge the first electric vehicle until the charging is completed; when the charging instruction generated by the platform based on the target electric vehicle identifier is to insert the second electric vehicle, the charging order for the second electric vehicle can be started in the case that the reinserted charger plug is determined to be the second charger plug of the second electric vehicle, so that the charging pile starts to charge the second electric vehicle.

[0063] The electric vehicle charging protection method provided by the application, when the cloud platform detects that the first charger plug of the first electric vehicle is unplugged, the first physical feature information of the unplugging user and the first appearance feature information of the first electric vehicle are obtained, and when the socket corresponding to the first charger plug is inserted into the second charger plug, the second physical feature information of the plugging user and the second appearance feature information of the second electric vehicle are obtained, and further the target electric vehicle identifier matched with the first physical feature information, the first appearance feature information, the second physical feature information and the second appearance feature information is determined. Since the target electric vehicle identifier represents the first electric vehicle or the second electric vehicle, the cloud platform can instruct the charging pile to continue to charge the first electric vehicle or to charge the second electric vehicle in the queue based on the target electric vehicle identifier, so as to achieve the purpose of timely and effectively determining the electric vehicle required to be charged at present, thereby greatly improving the efficiency of electric vehicle charging protection, and the practicability is also strong.

[0064] Optionally, the specific implementation process of step 130 can include:

[0065] The cloud platform determines that the user who unplugs the charger and the user who plugs in the charger are the same user and the first electric vehicle and the second electric vehicle are different electric vehicles based on the first physical feature information, the first appearance feature information, the second physical feature information, and the second appearance feature information; and determines the target electric vehicle identifier in the case that neither the user who unplugs the charger nor the user who plugs in the charger is the first user corresponding to the first electric vehicle, and the second charger plug is different from the first charger plug.

[0066] Specifically, the cloud platform performs similarity analysis on the first physical feature information and the second physical feature information, and determines that the user who unplugs the charger and the user who plugs in the charger are the same user when the similarity of the first physical feature information and the second physical feature information reaches a first preset similarity threshold. Similarly, the cloud platform also performs similarity analysis on the first appearance feature information and the second appearance feature information, and determines that the first electric vehicle and the second electric vehicle are different electric vehicles when the similarity of the first appearance feature information and the second appearance feature information is lower than a second preset similarity threshold. At this time, the cloud platform can determine that neither the user who unplugs the charger nor the user who plugs in the charger is the first user based on the pre-recorded physical feature information of the first user corresponding to the first electric vehicle, and in the case that the second charger plug is different from the first charger plug, it can be considered that the first charger plug is intentionally unplugged by the user who unplugs the charger, and the user who unplugs the charger has the illegal behavior of unplugging the first charger plug. At this time, the cloud platform can obtain the user account of the user who unplugs the charger or the user who plugs in the charger by the user who unplugs the charger or the user who plugs in the charger using the terminal device to scan the charging two-dimensional code in the case that the second charger plug of the second electric vehicle is inserted into the corresponding plug opening of the first charger plug, and control to prohibit or suspend the charging permission of the user account, and send an alarm information to the user who unplugs the charger or the user who plugs in the charger. The alarm information is used to warn the user who unplugs the charger or the user who plugs in the charger to reinsert the first charger plug that is unplugged into the corresponding plug opening, and determine the target electric vehicle identifier as the electric vehicle identifier of the first electric vehicle.

[0067] It should be noted that the alarm information sent by the cloud platform to the user who unplugs the charger or the user who plugs in the charger can also carry the remaining charging time of the first electric vehicle, which is used to prompt the user who unplugs the charger or the user who plugs in the charger to wait until the first electric vehicle finishes charging before charging. In addition, the cloud platform can also send the idle condition of other charging piles within the recent distance range and / or the remaining charging time of the charged electric vehicle to the user terminal corresponding to the user who unplugs the charger or the user who plugs in the charger, so as to facilitate the user who unplugs the charger or the user who plugs in the charger to select a charging pile that meets his actual needs for the second electric vehicle. Herein, no specific limitation is made.

[0068] The electric vehicle charging protection method provided by the application, the cloud platform determines the target electric vehicle identifier in the case that the user who unplugs the electric vehicle and the user who plugs in the electric vehicle are the same user and neither of them is the first user corresponding to the first electric vehicle, and the first electric vehicle and the second electric vehicle are different electric vehicles, thereby improving the flexibility and reliability of the cloud platform in determining the target electric vehicle identifier.

[0069] Optionally, in the case that the user who unplugs the electric vehicle and the user who plugs in the electric vehicle are neither the first user corresponding to the first electric vehicle nor the second electric vehicle plug-in charger plug is different from the first electric vehicle plug-in charger plug, the target electric vehicle identifier is determined, and the specific implementation process can include:

[0070] In the case that the user who unplugs the electric vehicle and the user who plugs in the electric vehicle are neither the first user nor the second electric vehicle plug-in charger plug is different from the first electric vehicle plug-in charger plug, the first terminal device corresponding to the first user is sent prompt information whether to authorize the second electric vehicle to charge in line, and if the first terminal device feedback refuses the second electric vehicle to charge in line within the first preset time or no feedback information is received, the protection operation for the first electric vehicle and the suspension of the charging permission operation for the second electric vehicle are started, the protection operation is used to alert the user who plugs in the first electric vehicle plug-in charger plug into the corresponding socket, and the target electric vehicle identifier is determined as the electric vehicle identifier of the first electric vehicle.

[0071] Specifically, in the case that the user who unplugs the electric vehicle and the user who plugs in the electric vehicle are the same user and neither of them is the first user, and the plug-in charger plug inserted into the corresponding socket of the first plug-in charger plug is the second plug-in charger plug of the second electric vehicle, the cloud platform can determine whether the second electric vehicle is authorized to charge in line by sending prompt information to the first terminal, and if the first terminal device feedback refuses within the first preset time or no feedback information is received, it is considered that the second electric vehicle does not have the right to charge in line, and the user who unplugs the electric vehicle and the user who plugs in the electric vehicle also have the illegal behavior of unplugging the first plug-in charger plug. At this time, the protection operation and the suspension of the charging permission operation are used to determine that the target electric vehicle identifier is the electric vehicle identifier of the first electric vehicle.

[0072] The electric vehicle charging protection method provided by the application, the cloud platform determines the target electric vehicle identifier in the case that the user who unplugs the electric vehicle and the user who plugs in the electric vehicle are the same user and neither of them is the first user corresponding to the first electric vehicle, and the first electric vehicle and the second electric vehicle are different electric vehicles, thereby improving the flexibility and reliability of the cloud platform in determining the target electric vehicle identifier.

[0073] Optionally, after sending the prompt information whether to authorize the second electric vehicle to charge in line to the first terminal device corresponding to the first user, the method provided by the application can further include:

[0074] If the first terminal device feeds back the authorization information of agreeing to the second electric vehicle to queue for charging within the first preset time length, it is determined that the target electric vehicle identifier is the electric vehicle identifier of the second electric vehicle.

[0075] Specifically, in the case that the user who unplugs the electric vehicle and the user who plugs the electric vehicle are the same user and neither of them is the first user, and the charger plug inserted into the plug hole corresponding to the first charger plug is the second charger plug of the second electric vehicle, the cloud platform sends prompt information to the first terminal whether to authorize the second electric vehicle to queue for charging. If the first terminal device feeds back the authorization information of agreeing to the second electric vehicle to queue for charging within the first preset time length, it can be considered that the user who unplugs the electric vehicle or the user who plugs the electric vehicle has a close relationship with the first user, such as friends, family or relatives, etc. At this time, it can be determined that the target electric vehicle identifier is the electric vehicle identifier of the second electric vehicle.

[0076] The electric vehicle charging protection method provided by the application, in the case that the user who unplugs the electric vehicle and the user who plugs the electric vehicle are the same user and neither of them is the first user corresponding to the first electric vehicle, and the first electric vehicle and the second electric vehicle are different electric vehicles, the cloud platform determines the target electric vehicle identifier as the electric vehicle identifier of the second electric vehicle by determining that the second electric vehicle has the right to queue for charging, so that the cloud platform determines the target electric vehicle identifier more flexibly and reliably.

[0077] Optionally, the specific implementation process of step 130 can further include:

[0078] Based on the first physical feature information, the first appearance feature information, the second physical feature information and the second appearance feature information, it is determined that the user who unplugs the electric vehicle and the user who plugs the electric vehicle are the same user and the first electric vehicle and the second electric vehicle are the same electric vehicle. In the case that the user who unplugs the electric vehicle is not the first user corresponding to the first electric vehicle and the second charger plug is the same plug as the first charger plug, it is determined that the target electric vehicle identifier is the electric vehicle identifier of the first electric vehicle.

[0079] Specifically, the cloud platform performs similarity analysis on the first physical feature information and the second physical feature information, and when the similarity of the first physical feature information and the second physical feature information reaches a first preset similarity threshold, it can be determined that the unplugging user and the plugging user are the same user. Similarly, the cloud platform also performs similarity analysis on the first appearance feature information and the second appearance feature information, and when the similarity of the first appearance feature information and the second appearance feature information reaches a second preset similarity threshold, it can be determined that the first electric vehicle and the second electric vehicle are the same electric vehicle. At this time, the cloud platform can determine that the unplugging user and the plugging user are not the first user based on the pre-recorded physical feature information of the first user corresponding to the first electric vehicle, and in the case that the second charger plug and the first charger plug are the same plug, it can be considered that the first charger plug is accidentally knocked off by the unplugging user, and the first charger plug is reinserted into the corresponding socket by the plugging user. Therefore, it can be determined that the target electric vehicle identifier is the electric vehicle identifier of the first electric vehicle.

[0080] The electric vehicle charging protection method provided by the application can ensure that the cloud platform determines the target electric vehicle identifier more flexibly and reliably.

[0081] Optionally, the specific implementation process of step 130 can further include:

[0082] Based on the first physical feature information, the first appearance feature information, the second physical feature information and the second appearance feature information, it is determined that the unplugging user and the plugging user are different users and the first electric vehicle and the second electric vehicle are different electric vehicles. In the case that the unplugging user is not the first user and the second charger plug and the first charger plug are different plugs, it is determined that the target electric vehicle identifier is the electric vehicle identifier of the second electric vehicle.

[0083] Specifically, the cloud platform performs similarity analysis on the first physical feature information and the second physical feature information, and when the similarity of the first physical feature information and the second physical feature information is lower than a first preset similarity threshold, it can be determined that the user who unplugs and the user who plugs are different users. Similarly, the cloud platform also performs similarity analysis on the first appearance feature information and the second appearance feature information, and when the similarity of the first appearance feature information and the second appearance feature information is lower than a second preset similarity threshold, it can be determined that the first electric vehicle and the second electric vehicle are different electric vehicles. At this time, the cloud platform can determine that the user who unplugs is the first user based on the pre-recorded physical feature information of the first user corresponding to the first electric vehicle, and in the case that the second charger plug and the first charger plug are different plugs, it can be considered that the first user has an urgent matter to go out and needs to end the charging in advance. At this time, the charging operation for the second electric vehicle can be performed and the protection operation for the first electric vehicle is not performed, so as to determine that the target electric vehicle identifier is the electric vehicle identifier of the second electric vehicle.

[0084] The electric vehicle charging protection method provided by the application, in the case that the cloud platform determines that the user who unplugs and the user who plugs are different users and the user who unplugs is the first user corresponding to the first electric vehicle, and the first electric vehicle and the second electric vehicle are different electric vehicles, the target electric vehicle identifier is determined as the electric vehicle identifier of the second electric vehicle, which further improves the flexibility and reliability of the cloud platform in determining the target electric vehicle identifier.

[0085] Optionally, the specific implementation process of step 130 can further include:

[0086] Based on the first physical feature information, the first appearance feature information, the second physical feature information and the second appearance feature information, it is determined that the user who unplugs and the user who plugs are different users and the first electric vehicle and the second electric vehicle are the same electric vehicle. In the case that neither the user who unplugs nor the user who plugs is the first user, and the second charger plug and the first charger plug are the same plug, the target electric vehicle identifier is determined as the electric vehicle identifier of the first electric vehicle.

[0087] Specifically, the cloud platform performs similarity analysis on the first physical feature information and the second physical feature information, and when the similarity of the first physical feature information and the second physical feature information is lower than a first preset similarity threshold, it can be determined that the unplugging user and the plugging user are different users. Similarly, the cloud platform also performs similarity analysis on the first appearance feature information and the second appearance feature information, and when the similarity of the first appearance feature information and the second appearance feature information reaches a second preset similarity threshold, it can be determined that the first electric vehicle and the second electric vehicle are the same electric vehicle. At this time, the cloud platform can determine that the unplugging user and the plugging user are not the first user based on the pre-recorded physical feature information of the first user corresponding to the first electric vehicle, and in the case that the second charger plug and the first charger plug are different plugs, it can be considered that the first charger plug is accidentally knocked off by the unplugging user and the first charger plug is reinserted into the corresponding socket by the plugging user. At this time, it can be determined that the target electric vehicle identifier is the electric vehicle identifier of the second electric vehicle.

[0088] The electric vehicle charging protection method provided by the application can effectively improve the flexibility and reliability of the cloud platform in determining the target electric vehicle identifier.

[0089] Optionally, the specific implementation process of step 130 can further include:

[0090] Based on the first physical feature information, the first appearance feature information, the second physical feature information and the second appearance feature information, it is determined that the unplugging user and the plugging user are different users and the first electric vehicle and the second electric vehicle are different electric vehicles. In the case that the unplugging user and the plugging user are not the first user and the second charger plug and the first charger plug are different plugs, the first time when the first charger plug is unplugged and the second time when the second charger plug is inserted into the socket are determined. In the case that the time interval between the first time and the second time meets the preset time interval, the target electric vehicle identifier is determined to be the electric vehicle identifier of the second electric vehicle.

[0091] Specifically, the cloud platform performs similarity analysis on the first biometric feature information and the second biometric feature information, and when the similarity of the first biometric feature information and the second biometric feature information is lower than a first preset similarity threshold, it can be determined that the unplugging user and the plugging user are different users. Similarly, the cloud platform also performs similarity analysis on the first appearance feature information and the second appearance feature information, and when the similarity of the first appearance feature information and the second appearance feature information is lower than a second preset similarity threshold, it can be determined that the first electric vehicle and the second electric vehicle are different electric vehicles. At this time, the cloud platform can determine that the unplugging user and the plugging user are not the first user based on the pre-recorded biometric feature information of the first user corresponding to the first electric vehicle, and when the first charger plug is different from the second charger plug, it can be determined that the first time when the first charger plug is unplugged and the second time when the second charger plug is inserted into the socket, and when the time interval between the first time and the second time satisfies the preset time interval, it can be considered that the first charger plug has not been reinserted into the socket within the preset time interval after being unplugged by the unplugging user by mistake. The charging pile is in an idle state at this time, and the plugging user inserting the second charger into the first charger corresponding socket belongs to normal charging behavior, so it can be determined that the target electric vehicle identifier is the electric vehicle identifier of the second electric vehicle.

[0092] It should be noted that although in the case that the unplugging user and the plugging user are different users different from the first user, the first electric vehicle and the second electric vehicle are different electric vehicles, although the first charger plug is not inserted into a new charger plug within a preset time interval after being unplugged, resulting in the charging pile reaching an idle state, and the second charger can be normally charged, in the case that the first electric vehicle has not reached a charging completion state, the cloud platform can also send warning information of charging interruption to the first terminal device corresponding to the first user in the form of voice warning and / or text warning, so as to timely resume the charging process of the first electric vehicle.

[0093] The electric vehicle charging protection method provided by the application, the cloud platform determines that the target electric vehicle identifier is the electric vehicle identifier of the second electric vehicle in the case that the unplugging user and the plugging user are different users and the unplugging user and the plugging user are not the first user corresponding to the first electric vehicle, and the first electric vehicle and the second electric vehicle are different electric vehicles, further improving the flexibility and reliability of the cloud platform in determining the target electric vehicle identifier.

[0094] Optionally, the specific implementation process of step 120 can include:

[0095] In a case that the first charger plug is inserted into the second charger plug in the second preset time period, an insertion identifier of the first charger plug inserted into the second charger plug is detected, and based on the insertion identifier, the second physical feature information of the plug-in user and the second appearance feature information of the second electric vehicle corresponding to the second charger plug are acquired.

[0096] The second preset time period can represent a time consumed by the plug-in user to move the second electric vehicle to the position of the first charger plug corresponding insertion port, such as 5min-10min. And the first charger plug can be the same as the second charger plug, or different.

[0097] Specifically, in a case that the first charger plug of the first electric vehicle is detected to be unplugged, the cloud platform can monitor whether a new charger plug is inserted into the first charger plug corresponding insertion port in the second preset time period. If the second charger plug is detected to be inserted into the first charger plug corresponding insertion port in the second preset time period, the information acquisition process of acquiring the second physical feature information of the plug-in user and acquiring the second appearance feature information of the second electric vehicle corresponding to the second charger plug can be started. The information acquisition process can refer to the foregoing embodiments. Details are not described herein.

[0098] It should be noted that, if the cloud platform detects that neither the first charger plug nor the second charger plug is inserted into the first charger plug corresponding insertion port in the second preset time period, it can be considered that the first charger plug is not reinserted into the corresponding insertion port after being unplugged by the user by accident. At this time, the warning information of the charging interruption can be sent to the first terminal device corresponding to the first electric vehicle in the form of voice warning and / or text warning, so as to timely resume the charging process of the first electric vehicle.

[0099] The electric vehicle charging protection method provided by the application, in a case that the cloud platform detects that the first charger plug corresponding insertion port is inserted into the second charger plug in the second preset time period, the information acquisition operation of acquiring the second physical feature information of the plug-in user and the second appearance feature information of the second electric vehicle corresponding to the second charger plug is started, which improves the necessity and rationality of acquiring the second physical feature information and the second appearance feature information, and provides sufficient basis for timely and effectively determining the electric vehicle required to be charged at present.

[0100] Optionally, the specific implementation process of step 110 can include:

[0101] Based on the detected unplugged identifier of the first charger plug of the first electric vehicle, it is judged whether the first electric vehicle is charged. In a case that the first electric vehicle is not charged, the first physical feature information of the unplugged user and the first appearance feature information of the first electric vehicle are acquired.

[0102] Specifically, when the cloud platform detects that the first charger plug is unplugged, it can be determined whether the first electric vehicle is fully charged. If it is determined that the first electric vehicle is not fully charged, the information acquisition process of acquiring the first physical feature information of the unplugging user and the first appearance feature information of the first electric vehicle is started. The information acquisition process can refer to the foregoing embodiments. Herein, no further description is given.

[0103] It should be noted that if the cloud platform determines that the first electric vehicle is fully charged, the information acquisition process of the first physical feature information of the unplugging user and the first appearance feature information of the first electric vehicle is not started, and the charging pile can start the charging operation for the electric vehicle corresponding to the newly inserted other charger plug. For example, when the newly inserted other charger plug is a second charger plug different from the first charger plug, the charging operation for the second electric vehicle corresponding to the second charger plug can be started.

[0104] The electric vehicle charging protection method provided by the application can start the information acquisition operation of acquiring the first physical feature information of the unplugging user and the first appearance feature information of the first electric vehicle when the cloud platform detects that the first charger plug is unplugged and the first electric vehicle corresponding to the first charger plug is not fully charged. Therefore, the necessity and rationality of acquiring the first physical feature information and the first appearance feature information can be effectively improved, thereby providing sufficient basis for subsequently determining the electric vehicle that needs to be charged in a timely and effective manner.
