[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0049] refer to Figure 1 , which shows a flow chart of the charge and discharge management method of an electric vehicle provided by an embodiment of the present disclosure. The method is executed by the electric vehicle. It should be noted that the method is executed by the electric vehicle. It should be noted that in any process of discharging the electric vehicle or charging the electric vehicle, the type of the plug connected to the electric vehicle is detected once to determine whether the plug connected to the electric vehicle is a discharge gun or a charging gun.

[0050] In step S101, when it is detected that the electric vehicle is connected to the discharge gun and the power discharged by the electric vehicle is not less than the external discharge power threshold, first reminder information is displayed to remind the user of the electric vehicle to determine whether the electric vehicle continues to discharge.

[0051] It should be noted that the electric vehicle may be any electric vehicle to which the method provided in the embodiments of the present disclosure can be applied.

[0052] The external discharge power threshold may be: the product of the maximum external discharge power of the electric vehicle and a preset percentage less than 1. The maximum external discharge power of the electric vehicle may be the rated external discharge power of the electric vehicle.

[0053] In a possible implementation, in step S101, the central control screen of the electric vehicle may display first reminder information for reminding the user of the electric vehicle to determine whether the electric vehicle continues to discharge the electric vehicle.

[0054] In step S101, first reminder information for reminding the user of the electric vehicle to determine whether the electric vehicle continues to discharge the electric vehicle may be displayed in a pop-up window displayed on the central control screen of the electric vehicle.

[0055] It should be noted that if the electric vehicle is connected to a discharge gun, before executing the charge and discharge management method for the electric vehicle provided by the embodiment of the present disclosure, the user of the electric vehicle inserts the discharge gun into an interface on the electric vehicle that is compatible with the discharge gun.

[0056] In the embodiment of the present disclosure, whether the plug gun connected to the electric vehicle is a discharge gun or a charge gun is identified by a unit for identifying the type of the plug gun of the electric vehicle.

[0057] In step S102 , when a first operation of the user of the electric vehicle instructing the electric vehicle not to continue discharging the electric vehicle is detected, the electric vehicle stops discharging the electric vehicle.

[0058] In step S102, the central control screen of the electric vehicle may display a first reminder message for reminding the user of the electric vehicle to determine whether the electric vehicle continues to discharge externally, a control indicating that the electric vehicle continues to discharge externally, such as a button named "continue to discharge externally", and a control indicating that the electric vehicle does not continue to discharge externally, such as a button named "stop discharge externally". The first operation of the user of the electric vehicle to instruct the electric vehicle not to continue to discharge externally may be: the user of the electric vehicle clicks the control indicating that the electric vehicle does not continue to discharge externally.

[0059] In step S103, when it is detected that the electric vehicle is connected to the charging gun and the charging device corresponding to the charging gun is a public charging pile, a second reminder message is displayed to remind the user of the electric vehicle to determine whether to continue locking the charging gun after charging of the electric vehicle is completed.

[0060] The charging gun is a component of a charging device corresponding to the charging gun or the charging gun can be connected to a charging device corresponding to the charging gun.

[0061] It should be noted that, if an electric vehicle is connected to a charging gun, before executing the method provided in the embodiment of the present disclosure, the user of the electric vehicle inserts the charging gun into an interface on the electric vehicle that is compatible with the charging gun.

[0062] In step S103, the central control screen of the electric vehicle may display a second reminder message for reminding the user of the electric vehicle to determine whether to continue locking the charging gun after the charging of the electric vehicle is completed, a control indicating that the charging gun is to be continued to be locked after the charging of the electric vehicle is completed, such as a button named "continue to lock the charging gun after charging is completed", and a control indicating that the charging gun is not to be continued after the charging of the electric vehicle is completed, such as a button named "unlock the charging gun after charging is completed". The second operation of the user of the electric vehicle to indicate that the charging gun is not to be continued to be locked after the charging of the electric vehicle is completed may be: the user of the electric vehicle clicks the control indicating that the charging gun is not to be continued after the charging of the electric vehicle is completed.

[0063] During the charging of the electric vehicle, the charging gun is in a locked state.

[0064] In one possible manner, the charging device corresponding to the charging gun can be determined to be a public charging pile or a home charging device according to the position of the electric vehicle when the electric vehicle is detected to be connected to the charging gun. The position of the public charging pile within a certain range near the electric vehicle can be obtained from the map data of the vehicle navigation.

[0065] In another possible implementation, a charging current threshold for distinguishing between public charging piles and household charging devices can be pre-set. When the allowable current of the charging gun is not less than, that is, greater than or equal to, the charging current threshold for distinguishing between public charging piles and household charging devices, it can be determined that the charging device corresponding to the charging gun is a public charging pile. When the allowable current of the charging gun is less than the charging current threshold, it can be determined that the charging device corresponding to the charging gun is a household charging device. The allowable current of the charging gun can be determined based on the resistance value of the resistor inside the charging gun that is related to the allowable current of the charging gun.

[0066] It should be noted that the allowable current of the charging gun can be understood as: the rated charging current of the charging gun, that is, the maximum charging current marked by the manufacturer of the charging gun.

[0067] As an example, the charging current threshold for distinguishing between public charging piles and home charging devices is 32A. When the allowable current of the charging gun is ≥32A, it can be determined that the charging device corresponding to the charging gun is a public charging pile. When the allowable current of the charging gun is <32A, it can be determined that the charging device corresponding to the charging gun is a home charging device.

[0068] In step S104, when it is detected that the user of the electric vehicle indicates that the second operation of not locking the charging gun will not continue after charging of the electric vehicle is completed, the charging gun is unlocked after charging of the electric vehicle is completed.

[0069] When the user of the electric vehicle indicates that the second operation of locking the charging gun will not be continued after the charging of the electric vehicle is completed, the charging gun will be unlocked after the charging of the electric vehicle is completed, so that the charging gun is switched from a locked state to a drawable state. After other users see the information that the charging of the electric vehicle is completed displayed on the screen of the public charging pile corresponding to the charging gun, other users can draw the charging gun, and other users can insert the charging gun into the interface compatible with the charging gun on other electric vehicles, and charge the other electric vehicles through the public charging pile corresponding to the charging gun. The utilization rate of public charging piles is improved.

[0070] refer to Figure 2 , which shows a flow chart of another method for managing charging and discharging of an electric vehicle provided by an embodiment of the present disclosure. The method is executed by the electric vehicle. It should be noted that in any process of discharging the electric vehicle or charging the electric vehicle, the type of the plug connected to the electric vehicle is detected to determine whether the plug connected to the electric vehicle is a discharge gun or a charging gun.

[0071] In step S201, when it is detected that the electric vehicle is connected to the discharge gun and the power discharged by the electric vehicle is not less than the external discharge power threshold, first reminder information is displayed to remind the user of the electric vehicle to determine whether the electric vehicle continues to discharge.

[0072] In step S202, when a first operation of the user of the electric vehicle instructing the electric vehicle not to continue external discharge is detected, external discharge is stopped.

[0073] In step S203, when it is detected that the electric vehicle is connected to the charging gun and the charging device corresponding to the charging gun is a public charging pile, a second reminder message is displayed to remind the user of the electric vehicle to determine whether to continue locking the charging gun after charging of the electric vehicle is completed.

[0074] In step S204, when it is detected that the user of the electric vehicle indicates that the second operation of not continuing to lock the charging gun after charging of the electric vehicle is completed, the charging gun is unlocked after charging of the electric vehicle is completed.

[0075] In step S205, when it is detected that the electric vehicle is connected to the charging gun and the charging device corresponding to the charging gun is a household charging device, a fourth reminder message is displayed to remind the user of the electric vehicle to determine whether it is necessary to set a reduced charging current of the charging gun; when it is detected that the user's instruction determines that the fourth operation of setting a reduced charging current of the charging gun needs to be set, the reduced charging current of the charging gun is set.

[0076] The derating charging current of the charging gun is less than the allowable current of the charging gun.

[0077] The derating charging current of the charging gun may be understood as: an upper limit value of the charging current of the charging gun set by the user of the electric vehicle.

[0078] In step S205, when the fourth operation of setting the derated charging current of the charging gun is detected, the charging current input by the user of the electric vehicle can be received, and the charging current input by the user of the electric vehicle can be set as the derated charging current of the charging gun. Alternatively, the current selected by the user of the electric vehicle from the displayed multiple candidate currents can be set as the derated charging current of the charging gun.

[0079] In step S205, the central control screen of the electric vehicle may display a fourth reminder message for reminding the user of the electric vehicle to determine whether to set the reduced charging current of the charging gun, a control indicating that the user needs to set the reduced charging current of the charging gun, such as a button named "need to set reduced charging current", and a control indicating that the user does not need to set the reduced charging current of the charging gun, such as a button named "do not need to set reduced charging current". The fourth operation of the user's instruction to determine that the reduced charging current of the charging gun needs to be set may be: the user of the electric vehicle clicks the control indicating that the user needs to set the reduced charging current of the charging gun.

[0080] In the embodiment of the present disclosure, a charging current upper limit value may be determined. The charging current upper limit value is: the maximum value of the current charged to the electric vehicle during the charging process of the electric vehicle. The current charged to the electric vehicle cannot exceed the charging current upper limit value.

[0081] In a possible implementation, the derated charging current of the charging gun may be determined as the upper limit value of the charging current.

[0082] In another possible implementation, the minimum value of the derated charging current of the charging gun and the reference current can be determined as the upper limit of the charging current. The reference current is one of the following items: the rated charging current of the battery on the electric vehicle, i.e., the maximum current allowed to be loaded by the battery on the electric vehicle, and the rated charging current of the charger on the electric vehicle.

[0083] In the disclosed embodiment, it is considered that in the process of charging the electric vehicle with a home charging device, if a large current equal to or slightly less than the allowable current of the charging gun is continuously used to charge the electric vehicle, the continuous large current may cause the cable of the home charging device or the socket of the home charging device to overheat and catch fire. When the fourth operation of the user's instruction to determine that the derating charging current of the charging gun needs to be set is detected, the derating charging current of the charging gun is set, thereby avoiding the situation in which the continuous large current may cause the cable of the home charging device or the socket of the home charging device to overheat and catch fire in the process of charging the electric vehicle with a home charging device, thereby protecting the home charging device. The safety of charging of electric vehicles is improved, and the level of refinement of the management of charging and discharging of electric vehicles is improved.

[0084] In a possible implementation, when the allowable current of the charging gun is less than a charging current threshold used to distinguish between a public charging pile and a home charging device, it can be determined that the charging device corresponding to the charging gun is a home charging device.

[0085] In a possible implementation, before displaying the first reminder information when it is detected that the electric vehicle is connected to the discharge gun and the power discharged by the electric vehicle is not less than the external discharge power threshold, it also includes: step S200. In step S200, when it is detected that the electric vehicle is connected to the discharge gun, a third reminder information is displayed to remind the user of the electric vehicle to determine whether to allow the electric vehicle to discharge externally; when the third operation of the user of the electric vehicle indicating that the electric vehicle is allowed to discharge externally is detected, external discharge is performed.

[0086] If the electric vehicle is connected to a discharge gun, before executing the charge and discharge management method for an electric vehicle provided by an embodiment of the present disclosure, the user of the electric vehicle inserts the discharge gun into an interface on the electric vehicle that is compatible with the discharge gun. After the user of the electric vehicle inserts the discharge gun into an interface on the electric vehicle that is compatible with the discharge gun, the electric vehicle can detect that the electric vehicle is connected to the discharge gun. A third reminder message for reminding the user of the electric vehicle to determine whether to allow the electric vehicle to discharge externally can be displayed in a pop-up window displayed on the central control screen of the electric vehicle. When the third operation of the user of the electric vehicle indicating that the electric vehicle is allowed to discharge externally is detected, the electric vehicle discharges externally.

[0087] In the disclosed embodiment, when it is detected that the electric vehicle is connected to the discharge gun, the user of the electric vehicle can be reminded whether to allow the electric vehicle to discharge externally, thereby preventing the electric vehicle from accidentally discharging and improving the refinement of the management of the charging and discharging of the electric vehicle.

[0088] In one possible implementation, in step S205, setting the derated charging current of the charging gun includes: displaying multiple combination information and the derated charging current corresponding to each combination information in the multiple combination information, wherein the combination information includes: charging cable material, charging cable wire diameter; setting the derated charging current of the charging gun to the derated charging current corresponding to the combination information selected by the user of the electric vehicle.

[0089] For a combination information, the reduced charging current corresponding to the combination information is: when the material of the charging cable of the household charging device is the charging cable material in the combination information and the wire diameter of the charging cable of the household charging device is the charging cable wire diameter in the combination information, it is more suitable for the reduced charging current of the charging gun corresponding to the household charging device.

[0090] Usually, the user of the electric car knows the charging cable material and charging cable wire diameter of the user's home charging device of the electric car, and the user of the electric car can select the reduced charging current corresponding to the charging cable material and charging cable wire diameter of the user's home charging device of the electric car.

[0091] In the disclosed embodiment, different combination information and the derated charging current corresponding to the different combination information can be provided to the user of the electric vehicle, thereby improving the convenience of the user of the electric vehicle in setting the derated charging current and improving the refinement of the management of the charging and discharging of the electric vehicle.

[0092] In step S206, when it is detected that the user's instruction determines that the fifth operation of setting the derated charging current of the charging gun is not necessary, step S2061 is executed. In step S2061, during the charging of the electric vehicle, an environmental image of the environment in which the electric vehicle is currently located is collected by the camera of the electric vehicle to determine whether there is an abnormal situation related to charging, and when it is determined that there is an abnormal situation related to charging, the charging of the electric vehicle is stopped.

[0093] As an example, situations such as smoke or fire in the charging device socket corresponding to the charging gun are all abnormal situations related to charging.

[0094] In one possible implementation, a neural network trained for identifying abnormal situations can be used to determine whether there is an abnormal situation related to charging. The neural network trained for identifying abnormal situations can be any neural network that performs binary classification based on images. The trained neural network receives an input image, and the output prediction result indicates the presence or absence of an abnormal situation. As an example, the trained neural network is a convolutional neural network (CNN), a deep neural network (DNN), etc. During the training of the neural network for identifying abnormal situations, the environmental image used for training is input into the neural network for identifying abnormal situations, and the loss between the prediction result output by the neural network for identifying abnormal situations and the label of the environmental image used for training is calculated, and the loss is used to update the parameters of the neural network for identifying abnormal situations. The label of the environmental image used for training indicates the presence or absence of an abnormal situation.

[0095] It should be noted that during the charging of the electric vehicle, step S2061 may be performed periodically according to a preset cycle duration.

[0096] In a possible implementation, step S207 is further included. In step S207-step S208.

[0097] In step S207, when it is detected that the electric vehicle is connected to the charging gun, the environmental image and operation record information of the environment in which the electric vehicle is currently located are stored, wherein the operation record information indicates the user operation performed by the user of the electric vehicle after the target reminder information is displayed, and the target reminder information is the second reminder information or the fourth reminder information.

[0098] The detection of the connection between the electric vehicle and the charging gun in step S203 is performed during the t-th charging of the electric vehicle. The environment in which the electric vehicle is currently located may refer to the environment in which the electric vehicle is located during the t-th charging of the electric vehicle.

[0099] In step S208, after storing the environmental image and operation record information of the environment in which the electric vehicle is currently located, when the electric vehicle is detected to be connected to the charging gun again and the environmental image of the environment in which the electric vehicle is located when the electric vehicle is detected to be connected to the charging gun again matches the stored environmental image, that is, the environmental image of the current environment, an operation corresponding to the user operation is performed.

[0100] When it is detected again that the environment image of the environment in which the electric vehicle is located when the electric vehicle is connected to the charging gun matches the stored environment image, it can be regarded as: the electric vehicle is in the current environment again.

[0101] The detection of the connection between the electric vehicle and the charging gun in step S203 is performed during the t-th charging of the electric vehicle, and the detection of the connection between the electric vehicle and the charging gun is performed during the t+1-th charging of the electric vehicle.

[0102] If the target reminder information is the second reminder information for reminding the user of the electric vehicle to determine whether to continue locking the charging gun after the charging of the electric vehicle is completed, and the user operation performed by the user of the electric vehicle after the target reminder information is displayed is the second operation indicating to determine not to continue locking the charging gun after the charging of the electric vehicle is completed, then the operation corresponding to the user operation may be to unlock the charging gun after the charging of the electric vehicle is completed. The operation corresponding to the user operation is performed during the charging process of the electric vehicle for the t+1th time.

[0103] If the target reminder information is the fourth reminder information for reminding the user of the electric vehicle to determine whether to set the reduced charging current of the charging gun, the user operation performed by the user of the electric vehicle after the target reminder information is displayed is the fourth operation indicating the need to set the reduced charging current of the charging gun, and the operation corresponding to the user operation may be setting the reduced charging current of the charging gun. The operation corresponding to the user operation is performed during the charging process of the electric vehicle for the t+1th time.

[0104] If the target reminder information is the fourth reminder information for reminding the user of the electric vehicle to determine whether it is necessary to set a reduced charging current of the charging gun, and the user operation performed by the user of the electric vehicle after displaying the target reminder information is the fifth operation indicating that it is not necessary to set a reduced charging current of the charging gun, then the operation corresponding to the user operation may be: during the t+1th charging of the electric vehicle, using an environmental image of the environment in which the electric vehicle is located captured by a camera of the electric vehicle to determine whether there is an abnormality related to charging, and when it is determined that there is an abnormality related to charging, stopping charging of the electric vehicle.

[0105] In the disclosed embodiment, when the electric vehicle is in the corresponding environment again, the user operation related to charging the electric vehicle that was performed by the user of the electric vehicle when the electric vehicle was previously in the corresponding environment can be directly executed. When the electric vehicle is in the corresponding environment again, there is no need to remind the user of the electric vehicle again to determine whether to perform the user operation related to charging the electric vehicle, which simplifies the operation of the user of the electric vehicle and improves the refinement of the management of charging and discharging of the electric vehicle.

[0106] refer to Figure 3 , which shows a flowchart of an example of charging and discharging management for an electric vehicle.

[0107] In this example, the user of the electric vehicle inserts the plug gun. After the user of the electric vehicle inserts the plug gun, the electric vehicle determines that the plug gun is connected to the electric vehicle. After the electric vehicle determines that the plug gun is connected to the electric vehicle, the electric vehicle determines that the plug gun is a charging gun or a discharging gun.

[0108] In this example, when the plug gun is a discharge gun and the power discharged by the electric vehicle is not less than the external discharge power threshold, the user of the electric vehicle is reminded to determine whether the electric vehicle continues to discharge. If the user determines that the electric vehicle does not continue to discharge, the discharge is stopped.

[0109] In this example, when the plug is a charging gun and the allowable current of the charging gun is ≥32A, the user of the electric vehicle is reminded to determine whether to continue to lock the charging gun after the charging of the electric vehicle is completed. When the plug is a charging gun and the allowable current of the charging gun is <32A, the user of the electric vehicle is reminded to determine whether to set a reduced charging current.

[0110] In this example, if the derated charging current is set, the upper limit of the charging current can be determined. If the derated charging current is not set, during the charging of the electric vehicle, an environmental image of the environment in which the electric vehicle is currently located is collected by the camera of the electric vehicle to determine whether there is an abnormal situation related to charging, and when it is determined that there is an abnormal situation related to charging, the charging of the electric vehicle is stopped.
