Description

Technical Field

[0001] The present application relates to the technical field of electric vehicles, and in particular to a charging control method, device and equipment. Background Art

[0002] Electric vehicles are cars that are powered by electricity, usually using high-efficiency rechargeable batteries or fuel cells as their power source. Since electricity is a secondary energy source, it can come from wind energy, hydropower, nuclear energy, thermal energy, solar energy and other sources. Therefore, it has less impact on the environment than traditional cars and has a wide range of application prospects.

[0003] In the prior art, when charging an electric vehicle, charging piles are generally used to achieve charging. Specifically, the charging station where the charging pile is located needs to be equipped with monitoring equipment. The license plate number of the entering electric vehicle is collected by the monitoring equipment and compared with the preset electric vehicle whitelist in the platform database. If the license plate number corresponding to the electric vehicle is in the whitelist of the charging pile, the charging pile will release the charging authority. When the vehicle enters the signal transmission range of the charging pile, the vehicle and pile are authenticated and interacted. After the match is successful, the vehicle and pile start the plug-and-charge function, that is, the user can directly insert the charging pile plug into the identified electric vehicle to automatically start charging.

[0004] It can be seen that the charging process in the prior art is heavily dependent on the monitoring equipment in the charging station where the charging pile is located.

[0063] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0064] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0065] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0066] Figure 1 The present invention provides a flow chart of a charging control method. The execution subject of the method may be a target electric vehicle, specifically a controller in the target electric vehicle. Optionally, the target electric vehicle may include but is not limited to electric bicycles, electric motorcycles, battery vehicles, electric vehicles, etc. that can be charged through charging piles. Figure 1 As shown, the charging control method may include:

[0067] S101. Acquire current positioning information of a target electric vehicle and location information of a target charging pile stored inside the target electric vehicle.

[0068] Optionally, the current positioning information of the target electric vehicle can be obtained by the target electric vehicle based on positioning technologies such as the BeiDou Navigation Satellite System (BDS), the Global Positioning System (GPS), and the Global Satellite Navigation System (GLONASS), which are not limited here. In some embodiments, the current positioning information of the target electric vehicle can also be obtained and sent to the target electric vehicle by a terminal device with positioning function held by the driver or passenger, which is not limited here. Optionally, the terminal device can include but is not limited to: mobile phones, tablet computers, wearable devices, etc., which are not limited here.

[0069] The function of the charging pile is similar to that of the gas pump in a gas station. It can be fixed on the ground or on the wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations, and can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging the electric vehicle. In an embodiment of the present application, the target charging pile is a charging pile stored in the internal memory of the target electric vehicle. It should be noted that the charging piles stored in the internal memory of the electric vehicle include one or more, and the target charging pile is a charging pile that can be used to charge the target electric vehicle. In some embodiments, the location information of at least one target charging pile can be pre-stored in the target electric vehicle. Further, the user can store the location information of at least one target charging pile in the target electric vehicle by editing, or the user can obtain and store the location information of at least one target charging pile through the target electric vehicle networking. The method of obtaining the location information of the target charging pile is not limited here.

[0070] S102: Determine a first distance between a target electric vehicle and a target charging pile according to current positioning information and position information.

[0071] S103: Obtain a judgment result based on the relationship between the first distance and the distance threshold.

[0072] In an embodiment of the present invention, the first distance can be calculated based on the current positioning information and the position information of the target charging pile, and the judgment result is used to characterize the size relationship between the first distance and the distance threshold, thereby realizing that the timing for the target electric vehicle to transmit the wireless signal outward can be determined based on the distance relationship between the target electric vehicle and the target charging pile, thereby effectively avoiding the target electric vehicle from continuously transmitting the wireless signal outward, thereby reducing the energy loss caused by the continuous transmission of the wireless signal by the wireless transmission module in the target electric vehicle, and avoiding the continuous transmission of the wireless signal from affecting the normal operation of other devices.

[0073] In some embodiments, the distance threshold may include one or more, wherein when the distance threshold includes multiple, the strength and frequency of the wireless signal transmitted by the target electric vehicle may be set according to the relationship between the first distance and the distance threshold. Of course, the specific setting method is not limited thereto.

[0074] S104: Based on the judgment result, a communication connection is established between the target electric vehicle and the target charging pile.

[0075] Among them, if the judgment result indicates that the distance between the target electric vehicle and the target charging pile is close and meets the preset distance requirement, a communication connection can be established between the target electric vehicle and the target charging pile. Under this communication connection, not only can the target electric vehicle and the target charging pile exchange information (for example, send communication instructions), but the target charging pile can also charge the target electric vehicle based on the communication connection to realize the charging function.

[0076] It is worth noting that the present application does not limit the communication connection method. Depending on the actual application scenario, the connection can be established based on WiFi, Bluetooth, radio frequency and other communication technologies.

[0077] In summary, an embodiment of the present application provides a charging control method, which can be applied to a target electric vehicle, and includes: obtaining the current positioning information of the target electric vehicle and the position information of the target charging pile stored inside the target electric vehicle; determining a first distance between the target electric vehicle and the target charging pile based on the current positioning information and the position information; obtaining a judgment result based on the relationship between the first distance and the distance threshold; and establishing a communication connection between the target electric vehicle and the target charging pile based on the judgment result. Compared with the prior art, the setting of the distance threshold can avoid the target electric vehicle from continuously transmitting wireless signals to the outside, reduce the energy loss caused by the continuous transmission of wireless signals by the wireless transmission module in the target electric vehicle, and avoid the continuous transmission of wireless signals affecting the normal operation of other devices.

[0078] In addition, it should be noted that the charging control method provided in the embodiment of the present application can reduce the cost of charging control because it does not require the installation of monitoring equipment in the charging station.

[0079] Figure 2 A schematic diagram of another charging control method provided in an embodiment of the present application. Optionally, the above distance threshold may include: a first threshold, such as Figure 2 As shown, the step of obtaining the judgment result based on the relationship between the first distance and the distance threshold may include:

[0080] S106: If it is determined that the first distance is less than or equal to the first threshold, a determination result of transmitting a wireless signal to the target charging pile is obtained.

[0081] The wireless signal includes: the charging mark of the target electric vehicle, the driving state of the target electric vehicle, and the wireless charging signal. Optionally, the charging mark of the target electric vehicle may include: the license plate number of the target electric vehicle, the equipment serial number of the engine, etc.; the driving state of the target electric vehicle may include: normal driving, midway parking, normal parking, etc., which are not limited here. Midway parking means that the electric vehicle stops in a non-power-off state, and normal parking means that the electric vehicle stops in a power-off state.

[0082] Optionally, the first threshold may be 1 km, 2 km, etc., which is not limited here and can be flexibly set according to actual application scenarios. When the target electric vehicle determines that the first distance is less than or equal to the first threshold, it can transmit a wireless signal to the target charging pile through the first preset wireless communication module, and the wireless signal may include a wireless charging signal, so that the target charging pile can perform a preset charging function according to the wireless signal.

[0083] In some embodiments, the first preset communication module may include but is not limited to: a WiFi module, a Bluetooth module, a radio frequency module, etc., which are not limited here.

[0084] Optionally, the distance threshold further includes: a second threshold, and the first threshold is greater than the second threshold, such as Figure 2 As shown, if it is determined that the first distance is less than or equal to the first threshold, after obtaining the judgment result of transmitting the wireless signal to the target charging pile, the following method may also be included:

[0085] S107: If it is determined that the first distance is less than or equal to the second threshold, establish a communication connection between the target electric vehicle and the target charging pile, so that the target charging pile performs a preset charging function according to the communication connection.

[0086] Among them, the second threshold value can represent the preset threshold value corresponding to when the target electric vehicle can interact with the target charging pile. Optionally, the second threshold value can be any value between 5 meters and 50 meters, for example, 20 meters, 30 meters, etc., which is not limited here and can be flexibly set according to the actual application scenario. When the target electric vehicle determines that the first distance is less than or equal to the second threshold value, it can establish a communication connection with the target charging pile, wherein the process of the communication connection can include an authentication process, which is not limited here, wherein, if the communication connection is successfully established, the target charging pile can execute a preset charging action to output electrical energy to the target electric vehicle, thereby achieving the purpose of charging the target electric vehicle.

[0087] It is worth noting that when the target electric vehicle determines that the first distance is less than or equal to the second threshold, the target electric vehicle can optionally continue to transmit wireless signals to the target charging pile to ensure that continuous wireless communication can be established with the target charging pile.

[0088] In summary, the application of the embodiment of the present application realizes the plug-and-charge function of the electric vehicle without setting up a monitoring device in the charging field where the charging pile is located, which can effectively reduce the charging cost; in addition, since the present application transmits a wireless signal to the target charging pile only when it is determined that the first distance between the target electric vehicle and the target charging pile is less than or equal to the first threshold, the energy loss caused by the continuous transmission of the wireless signal by the wireless transmission module can be reduced, and the continuous transmission of the wireless signal can be avoided. The normal operation of other devices can be avoided. Among them, other devices can be configured to identify preset wireless signals, such as terminal devices held by users with Bluetooth function turned on, which are not limited here.

[0089] Figure 3 A flow chart of another charging control method provided in an embodiment of the present application is shown as follows: Figure 3 As shown, if it is determined that the first distance is less than or equal to the first threshold, the determination result of transmitting a wireless signal to the target charging pile may include:

[0090] S201: If it is determined that the first distance is less than or equal to the first threshold, obtain the current power of the target electric vehicle.

[0091] S202: If it is determined that the current power level of the target electric vehicle is less than a preset power level threshold, a judgment result of transmitting a wireless signal to the target charging pile is obtained.

[0092] If it is determined that the first distance is less than or equal to the first threshold, the current power of the target electric vehicle may be obtained through the battery system of the target electric vehicle.

[0093] Optionally, the preset power threshold can be 10%, 15%, 20%, etc., which is not limited here and can be flexibly set according to the actual application scenario or the user's charging habits. After obtaining the current power of the target electric vehicle, it can be determined whether the current power of the target electric vehicle is less than the preset power threshold. If it is less than, it means that the current power of the target electric vehicle is low and there is a high probability that it needs to be charged. In this case, the target electric vehicle can transmit a wireless signal to the target charging pile.

[0094] By applying the embodiments of the present application, the timing of transmitting wireless signals by the target electric vehicle can be further optimized, the energy loss caused by the continuous transmission of wireless signals by the wireless transmission module can be further reduced, and the continuous transmission of wireless signals can be prevented from affecting the normal operation of other devices.

[0095] Figure 4 A flow chart of another charging control method provided in an embodiment of the present application is shown as follows: Figure 4 As shown, after obtaining the above judgment result of transmitting a wireless signal to the target charging pile, it also includes:

[0096] S301: Receive a charging permission message sent by a target charging pile.

[0097] S302: respond to a charging request sent by a charging gun user on a target charging pile according to the charging permission message.

[0098] S303: According to the charging request, a preset charging circuit of the target electric vehicle is turned on to charge the target electric vehicle.

[0099] In some embodiments, the target charging pile may open a charging window for the target electric vehicle according to the charging permission message.

[0100] Among them, after the target charging pile receives the wireless signal transmitted by the target electric vehicle, it can determine whether to allow charging for the target electric vehicle based on the wireless signal. If it is determined to be allowed, the target charging pile can send a charging permission message to the target electric vehicle based on the second preset communication module (WiFi module, Bluetooth module, radio frequency module, etc.) to indicate that the target charging pile determines that the target electric vehicle has been successfully authenticated. Furthermore, after the target electric vehicle receives the charging permission message, it can control the preset actuator to open the charging window of the target electric vehicle, that is, the charging door, to achieve the non-sensing opening of the charging window in the target electric vehicle, and improve the user's charging experience.

[0101] Based on the above description, it can be understood that at this time the charging window of the target electric vehicle has been opened, so the electric vehicle driver or the staff of the target charging pile can operate the charging gun to insert the charging interface exposed at the charging window. When the target charging pile detects that the charging gun has been inserted into the charging interface of the target electric vehicle, it can generate an operation to use the charging gun. In response to the use operation, the target charging pile can release the charging authority and send a charging request to the target electric vehicle to indicate that the target electric vehicle can be charged; after the target electric vehicle receives the charging request sent by the target charging pile, it can connect to the preset charging circuit of the target electric vehicle, wherein the preset charging circuit can specifically be a charging circuit between the charging gun and the power supply battery in the target electric vehicle, so that the target electric vehicle can be charged through the charging gun.

[0102] In some embodiments, after the target electric vehicle opens the charging window of the target electric vehicle according to the charging permission message, the charging state of the target electric vehicle can be set to the waiting state and the timing can be started, wherein in the waiting state, the target electric vehicle can be configured to allow the charging gun to be inserted into the charging interface exposed at the charging window. Optionally, if the timing time reaches the first preset time, and the target electric vehicle detects that the charging gun is not inserted into the charging interface exposed at the charging window, the target electric vehicle can control the preset actuator to close the charging window of the target electric vehicle, thereby improving the applicability of the present application. Among them, the first preset time can be 3 minutes, 5 minutes, etc., which is not limited here and can be flexibly set according to the actual application scenario.

[0103] Figure 5 A flow chart of another charging control method provided in an embodiment of the present application is shown as follows: Figure 5 As shown, the above method also includes:

[0104] S401. Analyze the driving status of the target electric vehicle according to the wireless signal.

[0105] S402: If it is determined that the driving state meets the preset driving state, a charging window of the target electric vehicle is opened.

[0106] Among them, the preset driving state can be a normal parking state. After the target electric vehicle transmits a wireless signal to the target charging pile, the target electric vehicle can analyze the driving state of the target electric vehicle according to the wireless signal to determine whether the driving state of the target electric vehicle meets the preset driving state. If it meets the preset driving state, the target electric vehicle can control the preset actuator to open the charging window of the target electric vehicle, that is, the charging door, so that the charging window in the target electric vehicle can be opened seamlessly without the participation of the driver of the target electric vehicle, thereby improving the user's charging experience.

[0107] S403: Receive a charging request sent by the target charging pile in response to the use operation of the charging gun.

[0108] S404: According to the charging request, a preset charging circuit of the target electric vehicle is turned on to charge the target electric vehicle.

[0109] Among them, after the target electric vehicle opens the charging window, steps S403 and S404 can be executed to charge the target electric vehicle through the charging gun. For the description of steps S403 and S404, please refer to the description of the above steps S303 and S304, which will not be repeated here.

[0110] Optionally, the receiving of the charging permission message sent by the target charging pile may include:

[0111] The target charging pile receives a charging permission message sent when it determines that the target electric vehicle has been successfully authenticated; wherein the successful authentication of the electric vehicle is used to indicate that the target charging pile determines that the charging identifier of the target electric vehicle in the wireless signal matches the preset charging identifier.

[0112] Among them, the target charging pile can be configured to include at least one preset charging identifier. It is understandable that if the target charging pile is configured to include multiple preset charging identifiers, the electric vehicles corresponding to the multiple preset charging identifiers can be charged through the target charging pile. Based on this description, in some embodiments, after receiving the wireless signal transmitted by the target electric vehicle, the target charging pile can parse the charging identifier of the target electric vehicle in the wireless signal, and determine whether there is a preset charging identifier matching the charging identifier of the target electric vehicle in the target charging pile. If so, it means that the target electric vehicle is allowed to be charged through the target charging pile, that is, the authentication of the target electric vehicle is determined to be successful; it is understandable that if it does not exist, it means that the target electric vehicle is not allowed to be charged through the target charging pile, that is, the authentication fails, such as a home charging pile installed by a home user.

[0113] In some embodiments, when the target charging pile performs authentication operations based on the charging identification and preset charging identification of the target electric vehicle, it can determine whether the target electric vehicle is successfully authenticated based on authentication algorithms such as single-item authentication and two-way authentication. It can be flexibly selected according to the actual application scenario and is not limited here.

[0114] Optionally, the wireless signal may further include: a preset function signal. Optionally, the preset function signal may instruct the target charging pile to perform a corresponding function mode. Optionally, the preset function signal may include: a preset light on signal, a voice control signal, an auxiliary reversing signal, etc. Correspondingly, the corresponding function mode may include: a preset light on mode, a voice control mode, an auxiliary reversing mode, etc. In some embodiments, by controlling the target charging pile to enter the preset light on mode, the user may be assisted in lighting, by controlling the target charging pile to enter the voice control mode, the user may be assisted in quickly controlling the target charging pile through voice, and by controlling the target charging pile to enter the auxiliary reversing mode, the user may be assisted in improving the reversing efficiency.

[0115] Accordingly, the target charging pile performs a preset charging function according to the wireless signal, including:

[0116] The target charging pile executes a preset charging function according to the wireless charging signal and sets a corresponding function mode according to the preset function signal.

[0117] Based on the above description, it can be understood that if the wireless signal can also include: a preset function signal, then the target electric vehicle transmits a wireless signal to the target charging pile, which can enable the target charging pile to perform the preset charging function according to the wireless charging signal and set the target charging pile to enter the corresponding function mode according to the preset function signal, as described above, for example, it can include but is not limited to: preset light on mode, voice control mode, assisted reversing mode, etc.

[0118] In summary, by applying the embodiments of the present application, the target charging pile can be fully utilized and different functional modes can be configured for the target charging pile to meet the needs of users in different application scenarios and improve the user experience of using the target charging pile.

[0119] Figure 6 A flow chart of another charging control method provided in an embodiment of the present application is shown as follows: Figure 6 As shown, optionally, after the preset charging circuit of the target electric vehicle is turned on according to the charging request and the target electric vehicle is charged, the method further includes:

[0120] S501. Stop transmitting wireless signals to the target charging pile.

[0121] Among them, it can be understood that after charging the target electric vehicle through the charging gun, it is not very meaningful for the target electric vehicle to transmit wireless signals at this time. Optionally, in this case, the transmission of wireless signals to the target charging pile can be stopped. In this way, unnecessary wireless signals can be avoided as much as possible, further reducing the energy loss caused by the continuous transmission of wireless signals by the wireless transmission module, and further avoiding the continuous transmission of wireless signals affecting the normal operation of other devices.

[0122] In some embodiments, taking into account certain scenarios, for example, the target electric vehicle transmits a wireless signal to the target charging pile, and the target electric vehicle still does not receive the charging permission message sent by the target charging pile within the second preset time, in this scenario, the target charging pile may be out of power, damaged or occupied. Optionally, the target electric vehicle can stop transmitting wireless signals to the target charging pile to avoid invalid transmission of wireless signals. Optionally, the target electric vehicle can also generate a preset prompt message to prompt the user to pay attention. In this way, the applicability of the method of the present application can be improved.

[0123] Figure 7 A flow chart of another charging control method provided in an embodiment of the present application is provided. The execution subject of the method may be a target charging pile that can charge the target electric vehicle, such as Figure 7 As shown, the method may include:

[0124] S601. Receive a wireless signal transmitted by a target electric vehicle when it is determined that a first distance is less than or equal to a first threshold.

[0125] The first distance is calculated and obtained by the target electric vehicle according to the current positioning information and the position information of the target charging pile, and the wireless signal includes: the charging mark of the target electric vehicle, the driving status of the target electric vehicle, and the wireless charging signal.

[0126] S601: If it is determined through the target electric vehicle that the first distance is less than or equal to the second threshold, establish a communication connection with the target electric vehicle and execute a preset charging function.

[0127] Referring to the above description, it can be seen that the target charging pile can receive a wireless signal transmitted by the first preset wireless communication module when the target electric vehicle determines that the first distance is less than or equal to the first threshold value. The wireless signal may include a wireless charging signal. Furthermore, when the target electric vehicle determines that the first distance is less than or equal to the second threshold value, it can establish a communication connection with the target charging pile. That is, at this time, the target charging pile can establish a communication connection with the target electric vehicle and execute a preset charging action to output electrical energy to the target electric vehicle, thereby achieving the purpose of charging the target electric vehicle.

[0128] By applying the embodiments of the present application, the plug-and-charge function of the electric vehicle can be realized without setting up a monitoring device in the charging field where the charging pile is located, which can effectively reduce the charging cost; in addition, since the present application transmits a wireless signal to the target charging pile only when it is determined that the first distance between the target electric vehicle and the target charging pile is less than or equal to the first threshold, the energy loss caused by the continuous transmission of the wireless signal by the wireless transmission module can be reduced, and the continuous transmission of the wireless signal can be avoided.
