Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electric vehicle charging, and particularly relates to a charging method and system for electric vehicles. BACKGROUND

[0002] With the explosive growth of electric vehicles, the number of electric vehicles in the private car field is increasing year by year, and the country advocates that private electric vehicles use private charging piles to meet the energy supplement needs of home electric vehicles. In recent years, the degree of intelligence of electric vehicles is getting higher and higher, and the communication between private charging piles and vehicles to realize plug-and-charge has become a trend. The current common technical solution cannot match the charging specifications of each manufacturer, so one charging pile can only correspond to one electric vehicle. If a user's home has multiple electric vehicles, multiple charging piles need to be installed to realize plug-and-charge. If multiple charging piles are provided for each user with multiple vehicles, it will cause a huge waste of input cables and labor costs. This not only increases unnecessary investment, but also wastes the power capacity of the community invisibly.

[0003] Because the power capacity of the community is limited, it is impossible to configure multiple charging piles for a household. If only one charging pile can be installed, the user can only realize plug-and-charge for one vehicle, and the charging of other vehicles needs to be controlled through other means, causing unnecessary trouble to the user.

[0045] In the following description, specific details such as specific system structures, techniques, etc. are presented in order to thoroughly understand the embodiments of the present application. However, it should be clear to those skilled in the art that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, circuits and methods are omitted in order not to obscure the description of the present application with unnecessary details.

[0046] Embodiment 1

[0047] Referring to Figure 1 An embodiment of a charging method of an electric vehicle provided by the present application includes the following steps:

[0048] S1, the charging pile searches for a connectable vehicle which has established a binding relationship with the charging pile.

[0049] It should be noted that before step S1, the connectable vehicle needs to establish a binding relationship with the charging pile. When the vehicle and the charging pile are bound, the charging pile and the vehicle are generally bound through manual operation of the user. For example, the binding method includes writing the identity information of the vehicle into the charging pile through the APP. For example, the vehicle is first communicatively connected with the mobile terminal, the identity information of the vehicle is obtained through the APP on the mobile terminal, and then the identity information of the vehicle is transmitted to the charging pile through the APP on the mobile terminal. Or write the charging pile information into the vehicle memory, for example, upload the identity information of the charging pile to the vehicle computer in the form of near field communication, and the vehicle computer sends a binding protocol to the charging pile according to the identity information of the charging pile, so that the charging pile and the vehicle are bound. Or the binding is realized through specific operation action combination of the vehicle and the charging pile, for example, when the charging interface of the vehicle is directly connected with the charging pile, if the charging pile finds that the vehicle is not bound with the charging pile, the identity information of the vehicle is automatically obtained from the vehicle to bind the charging pile and the vehicle. It should be noted that the vehicle here can include multiple vehicles, after one of the vehicles is bound with the charging pile, the remaining vehicles repeat the above binding operation, and are sequentially bound with the charging pile until all the vehicles are sequentially bound with the charging pile.

[0050] Further, the charging pile needs to receive a first operation of the user before searching for the connectable vehicle. For example, the first operation can include the user removing the charging gun from the charging gun seat of the charging pile, the user pressing a specific key on the charging gun or the charging pile, the user inserting the charging gun into the vehicle charging socket, etc. The above first operation can also include the vehicle completing parking, the user opening and closing the door, opening the charging socket cover, etc.

[0051] S2, the charging pile establishes a communication connection with the first target vehicle according to the preset condition from the connectable vehicle.

[0052] It should be noted that the preset condition can include priority information of the connectable vehicle, binding sequence of the connectable vehicle, distance between the connectable vehicle and the charging pile, or vehicle state information of the connectable vehicle.

[0053] Referring to Figure 2In the embodiment, the preset condition is priority information of the connectable vehicle, and the priority information can be set by the user. The user can set the priority information of the connectable vehicle through an APP of a mobile terminal, a charging pile or a vehicle connected to the charging pile. For example, the user can obtain a list of all connectable vehicles on the APP, set the priority of any vehicle in the list of connectable vehicles, set the connection priority of vehicle A in the list to the highest level 1, and set the connection priority of vehicle B in the list to the next highest level 2. When the user sets the priority information, if the charging pile simultaneously searches for the connectable vehicle A and the connectable vehicle B, the charging pile will preferentially connect the vehicle A with the higher priority among the connectable vehicles.

[0054] In some embodiments, if the user does not set the priority information of the connectable vehicle, the charging pile will automatically set the priority of the connectable vehicle by default according to the binding sequence of the connectable vehicle or the distance between the connectable vehicle and the charging pile. The binding sequence of the connectable vehicle is the sequence in which the user writes the vehicle information in the APP. The priority of the connectable vehicle whose vehicle information is written first is set to the highest, or the priority of the connectable vehicle closest to the charging pile at the current time is set to the highest.

[0055] In some embodiments, the preset condition can also be a condition other than the priority information. In this embodiment, the preset condition can also be that the vehicle state information of the connectable vehicle satisfies a charging requirement. The charging pile state information can include, for example, whether the charging pile is charging, the location of the charging pile, and the charging pile encryption field for authentication. The vehicle state information can also include, for example, but is not limited to, vehicle power information, vehicle location information, and the like. The charging requirement can include, for example, but is not limited to, the following requirements: the doors of the connectable vehicle are locked; there is a person near the connectable vehicle; the power of the connectable vehicle is lower than a preset value; and the distance between the connectable vehicle and the charging pile is less than a preset value. If the connectable vehicle satisfies one of the charging requirements, or simultaneously satisfies multiple charging requirements, the connectable vehicle can be selected as the first target vehicle. For example, the charging pile first determines whether the vehicle needs to be charged according to the vehicle power information. For example, when the power of the vehicle is lower than a certain set threshold, the charging pile considers that the vehicle needs to be charged. Then, the charging pile detects whether it can charge. For example, the charging pile is checked for faults, and it is detected whether the charging gun is in a charging state or connected to the vehicle. When the charging pile has no faults, and the charging gun is not connected to the vehicle for charging, the charging pile is in a chargeable state. At the same time, the charging pile determines whether the vehicle is close enough to the vehicle according to the location information of the charging pile and the location information of the vehicle, so that the charging gun of the charging pile can be connected to the charging interface of the vehicle. If the charging pile and the connectable vehicle simultaneously satisfy the above requirements, the connectable vehicle is the first target vehicle. In some specific cases, there can be multiple target vehicles that simultaneously satisfy the charging requirements. In this case, the user can select a suitable first target vehicle from the multiple target vehicles through the charging pile or the mobile terminal APP.

[0056] It should be noted that in the above embodiments, the preset condition can also satisfy the charging requirement not only by the priority information of the connectable vehicle or the vehicle state information of the connectable vehicle, but also by other preset conditions according to the user's demand, such as the charging balance information of the vehicle. In the specific implementation process, the present method only selects the appropriate target vehicle by a single preset condition, so in some embodiments, the priority information of the connectable vehicle is taken as the first preset condition, and the vehicle state information of the connectable vehicle is taken as the second preset condition. The combination of the first preset condition and the second preset condition is used to select the appropriate target vehicle. For example, the user connects to the vehicle with the highest priority in the connectable vehicle through the priority information of the connectable vehicle, and then obtains the vehicle state information of the vehicle with the highest priority in the connectable vehicle to determine whether it meets the charging requirement. If the connectable vehicle does not meet the charging requirement, the user will determine whether the vehicle with the next lower priority meets the charging requirement according to the priority information, until a connectable vehicle that meets the charging requirement is found. The charging pile selects the connectable vehicle as the first target vehicle. In addition, when the charging pile successfully establishes a communication connection with the first target vehicle, the vehicle and the charging pile will stop the connection attempt action and will not continue to connect to other vehicles.

[0057] Referring to Figure 3 When the first preset condition is the priority information of the connectable vehicle, the charging pile has established a communication connection with the first target vehicle according to the priority information of the connectable vehicle. At this time, the charging pile obtains the state information of the first target vehicle through the communication connection with the first target vehicle to determine whether the first target vehicle meets the charging requirement. In this embodiment, the first target vehicle needs to meet the following conditions to meet the charging requirement:

[0058] 1. The first target vehicle is within the connectable range of the charging gun of the charging pile;

[0059] 2. The power of the first target vehicle is lower than the preset threshold;

[0060] 3. The first target vehicle is bound to the charging pile.

[0061] Since the charging pile and the first target vehicle are connected through a near field communication protocol, which includes but is not limited to Bluetooth, wifi, radio frequency, NFC and the like, the charging pile can directly determine that the first target vehicle is within a certain distance of the charging pile, because the near field communication protocol has a certain distance limit. Therefore, it is not necessary to determine whether the first target vehicle meets the requirement of being within the connectable range of the charging gun of the charging pile in the charging requirement. At the same time, the data transmission amount between the charging pile and the first target vehicle can be reduced. In the agreed near field communication protocol, the charging pile and the vehicle can send relevant information to each other. For example, the vehicle sends the vehicle identity information, the current state information of the vehicle, and the encryption protocol to the charging pile. After receiving the above information, the charging pile verifies that the first target vehicle has been bound to the charging pile, and also obtains the power information of the first target vehicle. After the charging pile successfully verifies the vehicle identity information, it feeds back the identity information, state information and encryption protocol feedback information of the charging pile to the first target vehicle. Since the first target vehicle has been bound to the charging pile, the first target vehicle will automatically communicate with the charging pile. For example, when the first target vehicle travels to a position within a certain distance from the charging pile, a communication channel is established between the charging pile and the first target vehicle through the near field communication protocol. The first target vehicle can use the same communication means as when it is bound to the charging pile to communicate with the charging pile. It should be noted that when the first target vehicle communicates with the charging pile through the mobile terminal APP, it needs to receive the user's confirmation of the operation of establishing a communication connection between the charging pile and the first target vehicle. The operation here can be that the user confirms the connection of the first target vehicle and the charging pile through the APP, or it can be that the user confirms the operation on the operation panel of the charging pile, or it can be that the user confirms the operation of charging on the vehicle.

[0062] In another embodiment, the user can preliminarily screen the vehicle through the first preset condition described above. For example, the user can set the priority information of the connectable vehicle as the first preset condition. If there are multiple connectable vehicles within the connectable range of the charging pile, the vehicle with the highest charging priority is selected as the first candidate vehicle. The charging pile further determines whether the first candidate vehicle has the right to establish a communication connection according to the vehicle information of the first candidate vehicle through the third preset condition. For example, in this embodiment, the third preset condition is that the connectable vehicle has a balance in the charging account. The charging pile obtains the charging account information of the first candidate vehicle through networking according to the vehicle information of the first candidate vehicle. If the first candidate vehicle has a balance in the charging account, the charging pile is connected to the first candidate vehicle, and the charging right is released to the first candidate vehicle. When the charging gun of the charging pile is connected to the first candidate vehicle, the charging is automatically started. If the balance in the charging account of the first candidate vehicle is used up or insufficient for the charging service, the charging pile selects a second candidate vehicle according to the first preset condition, and further determines whether the second candidate vehicle has the right to establish a communication connection through the third preset condition. In this embodiment, the second candidate vehicle is the vehicle with the second highest priority among the connectable vehicles. If the second candidate vehicle has a balance in the charging account, the charging pile is connected to the second candidate vehicle, and the charging right is released to the first candidate vehicle. When the charging gun of the charging pile is connected to the first candidate vehicle, the charging is automatically started.

[0063] In some embodiments, the user can actively modify the state of the charging pile and the vehicle to disconnect the communication connection between the vehicle and the charging pile, for example, by modifying the state information of the vehicle or the charging pile on the APP, or modifying the charging right of the vehicle on the charging pile, or actively driving the vehicle away from the connection range of the charging pile. After the communication connection between the vehicle and the charging pile is disconnected, the charging pile will automatically attempt to connect to other connectable vehicles.

[0064] S3, the charging pile grants the first target vehicle with the charging right.

[0065] After the first target vehicle establishes a communication connection with the charging pile, the charging pile sends a charging authentication request information to the first target vehicle.

[0066] The charging pile receives the charging authentication information fed back by the first target vehicle.

[0067] The charging pile generates a charging right verification result of the first target vehicle according to the charging authentication information.

[0068] If the charging right verification result is passed, the charging pile grants the first target vehicle with the charging right.

[0069] The first target vehicle sends charging authentication information to the charging pile after receiving the charging pile charging authentication request information, and the charging authentication information includes an authentication encryption field. The charging pile decrypts the authentication encryption field and generates a charging permission verification result according to the decryption result. When the authentication encryption field matches the pre-stored authentication field of the charging pile, the charging permission verification result is passed, otherwise it is not passed.

[0070] Embodiment 2

[0071] Further, the above method is described by specific examples.

[0072] When the charging pile searches for a connectable vehicle, the charging pile receives a first operation of a user;

[0073] In response to the first operation, the charging pile searches for the connectable vehicle;

[0074] The first operation includes an interaction operation of the user with the charging pile or an interaction operation of the user with the connectable vehicle.

[0075] Before the charging pile searches for the connectable vehicle, all the connectable vehicles need to be bound to the charging pile. The charging pile or the mobile phone APP receives a second operation of a user, and the second operation is used to trigger the charging pile to bind a to-be-bound vehicle;

[0076] The charging pile responds to the second operation to obtain vehicle identity information of the to-be-bound vehicle;

[0077] The charging pile binds the identity information of the charging pile and the vehicle identity information;

[0078] The to-be-bound vehicle is the first target vehicle or the second target vehicle.

[0079] Taking a mobile phone APP as an example, first, the user can register the charging pile information on the APP. The charging pile information can be obtained by scanning the two-dimensional code on the charging pile by the mobile phone. The user performs a second operation by the mobile phone, for example, manually inputs the vehicle identity information, and registers the vehicles owned by the user on the mobile phone APP one by one. The charging pile and the vehicles owned by the user are bound through the mobile phone APP, and the identity information of the vehicle bound to the charging pile is sent to the charging pile. The identity information of the vehicle bound to the charging pile can be sent to the charging pile by the user through the APP or the near field communication program.

[0080] In the daily use process, the charging pile searches for the connectable vehicle in the vicinity by using the near field communication protocol. Only the vehicle bound on the mobile phone APP can be searched by the charging pile.

[0081] When there is only one connectable vehicle in the near field communication protocol range of the charging pile, the charging pile directly determines the connectable vehicle as the first target vehicle and directly communicates with the connectable vehicle; if there are multiple bound connectable vehicles in the near field communication protocol range of the charging pile, for example, connectable vehicle A and connectable vehicle B exist at the same time, the charging pile can determine whether the first target vehicle is vehicle A or vehicle B according to the priority set by the user on the mobile phone APP. In this embodiment, the user sets the priority of connectable vehicle A to be higher than that of connectable vehicle B on the mobile phone APP. Therefore, the charging pile selects connectable vehicle A as the first target vehicle for communication connection according to the priority information after receiving the first operation of the user (for example, the user removes the charging gun or presses a specific button on the charging pile).

[0082] Before the charging pile and the first target vehicle establish communication connection, the connectable vehicle A sends vehicle state information to the charging pile, and the charging pile determines whether the vehicle and the charging pile meet the charging requirement according to the charging state of the charging pile and the vehicle state information. The charging state of the charging pile includes whether the charging gun is connected to the vehicle and whether the charging pile can normally charge, etc. When the charging gun is connected to the charging interface of the vehicle and the charging pile does not malfunction and can normally charge, the charging pile is in a releasable charging state. The vehicle state information includes the power information of the vehicle, etc. When the power of the vehicle is lower than a certain set threshold, the vehicle meets the charging requirement. When the charging pile and the vehicle meet the charging requirement at the same time, the charging pile and the first target vehicle confirm to establish communication connection. Then, the first target vehicle sends encrypted charging authentication request information to the charging pile. The charging authentication request information includes an encrypted authentication character group. The charging pile decrypts the authentication character group, and determines whether the connectable vehicle A has charging permission according to the authentication result of the authentication character group.

[0083] When the connectable vehicle A and the charging pile establish communication connection, and the connectable vehicle A has charging permission, the charging pile charges the connectable vehicle A.

[0084] If the connectable vehicle A cannot meet the charging requirements, or a higher priority vehicle appears within the connectable range of the charging pile, the charging pile will automatically or according to the user's selection disconnect the communication connection between the connectable vehicle A and the charging pile, and reselect the first target vehicle. For example, the user adjusts the priority of the connectable vehicle B to be higher than that of the connectable vehicle A. At this time, the connectable vehicle B is the highest priority vehicle that the charging pile can search. The connectable vehicle B sends vehicle state information to the charging pile. The charging pile determines whether the vehicle and the charging pile meet the charging requirements according to the charging state of the charging pile and the vehicle state information, and determines whether the connectable vehicle B has charging permission. If the connectable vehicle B cannot meet the charging requirements, and the connection between the charging gun and the connectable vehicle A is not disconnected, the charging pile continues to charge the connectable vehicle A. If the connectable vehicle B meets the charging requirements, even if the charging gun is connected to the connectable vehicle A, the charging pile does not continue to charge the connectable vehicle A.

[0085] When the charging pile starts charging any connectable vehicle among all the connectable vehicles within the connection range of the near field communication protocol of the charging pile, the communication connection with other connectable vehicles is stopped. After the charging pile interrupts the charging, the communication connection with the user-selected connectable vehicle, the lower-priority connectable vehicle, or other connectable vehicles that meet the charging conditions can be reestablished, so that other connectable vehicles can achieve plug-and-charge.

The authentication module is used to determine whether the first target vehicle meets the second preset condition and to detect whether the charging pile itself can charge; the second preset condition is used to determine whether the first target vehicle meets the charging requirements. When the first target vehicle meets the second preset condition and the charging pile meets the charging requirements, the charging pile grants charging permission to the first target vehicle and charges the first target vehicle; when the first target vehicle does not meet the second preset condition, the charging pile disconnects the communication connection with the first target vehicle and selects a second target vehicle from the connectable vehicles to establish a communication connection; the first target vehicle needs to meet the charging requirements to simultaneously meet the following conditions: the first target vehicle is within the connectable range of the charging gun of the charging pile; the battery level of the first target vehicle is lower than a preset threshold; the first target vehicle is bound to the charging pile; when the charging gun is connected to the vehicle's charging interface and the charging pile is not malfunctioning and can charge normally, the charging pile is in a release charging state; The charging pile grants charging permission to the first target vehicle by: sending a charging authentication request to the first target vehicle; receiving charging authentication information from the first target vehicle; generating a charging permission verification result for the first target vehicle based on the charging authentication information; and if the charging permission verification result is successful, then the charging pile grants charging permission to the first target vehicle. The electric vehicle charging device is also used to: when a vehicle with higher priority appears within the connection range of the charging pile, the charging pile will automatically, or according to the user's choice, disconnect the communication connection with the connectable vehicle and reselect the first target vehicle.
