[0056] Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0057] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0058] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0059] <Method Example>

[0060] Figure 1 A flow chart of a battery charging control method according to an embodiment of the present disclosure is shown as follows: Figure 1 As shown, the method includes steps S1100-S1400, wherein steps S1100-S1400 can be implemented by a cloud server.

[0061] S1100, obtaining the current positioning data of the battery. The battery in the present disclosure refers to a battery used to charge an electric vehicle, and the battery is provided with a positioning module, which can obtain the current positioning data of the battery at a preset frequency, and send the obtained current positioning data and an identity identifier that uniquely identifies the battery to a cloud server, so that the cloud server can obtain the identity identifier of the battery and the current positioning data.

[0062] After the current location data of the battery is obtained, step S1200 may be executed to determine whether the battery is in a pre-defined charging control area based on the current location data.

[0063] It should be noted that before executing this step, it is necessary to first execute the operation of constructing a charging control area. The charging control area is an area where charging needs to be safely controlled, such as a residential area. In a possible implementation, when constructing a charging control area, the following steps may be included:

[0064] First, load the map data of the target area. The target area is the geographical area to which the battery charging control method of the present disclosure is applicable, and the target area can be set according to the specific application scenario. For example, if you want to use the battery charging control method in area A, you can set the target area to area A. When the target setting area is set to area A, when constructing the charging control area, the map data including area A will be loaded as the map data of the target area.

[0065] Second, obtain the regional scope of the charging control area outlined by the user in the map data of the target area. It should be noted here that after determining the charging control area, the user needs to use the map processing tool to outline the regional scope of the charging control area in the map data of the target area. In this way, after the outline is completed, the regional scope of the charging control area outlined by the user can be obtained. For example, when the target area is area A and the charging control area is defined as residential area B located in area A, the user needs to outline the regional scope of residential area B located in area A from the map data of area A after loading the map data of area A, and use the outlined regional scope of residential area B as the regional scope of the charging control area.

[0066] Third, the charging control area is constructed according to the regional scope of the charging control area. Specifically, for the regional scope of the charging control area outlined, the area in the map data covered within the regional scope of the charging control area is used as the charging control area. After the charging control area is constructed, the regional scope of the charging control area will also be recorded, so that it can be judged whether the battery has entered the charging control area based on the regional scope of the charging control area.

[0067] The following is a specific example to illustrate the process of charging control area. Specifically, when building a charging control area, you can call the API interface of Baidu Map to load the map data of the target area. After the map data of the target area is loaded, trigger any area selection control (i.e. Figure 2 In the figure, there are three polygon controls on the right side. When any area selection control is triggered, the area range of the charging control area (i.e. Figure 2The area covered by the gray heart-shaped area is the charging control area. After the charging control area is drawn, click the drawn charging control area to push the following Figure 2 The information entry interface shown. The basic area information of the charging control area can be set through this information entry interface, wherein the basic area information includes the area name, the lowest altitude (i.e., the lowest elevation), the highest altitude (i.e., the lowest elevation) and the satellite positioning signal type of the area, and the satellite positioning signal type includes at least one of LBS positioning and GPS positioning. After completing the setting of the above basic area information, click the Save control on the information entry interface, and the system will obtain the basic area information and area range data of the charging control area, and store it in the database as the data of the charging control area.

[0068] The regional range data of the charging control area is determined according to the latitude and longitude data of multiple boundary points constituting the charging control area. Figure 2 The longitude and latitude data of the small square at the edge of the gray heart-shaped area in the figure are stored in order, and the regional range data of the charging control area can be obtained. That is, the regional range data of each charging control area is composed of the longitude and latitude data of multiple boundary points arranged in order.

[0069] After the construction of the charging control area is completed, it can be determined whether the battery is in the pre-defined charging control area based on the current positioning data of the battery. Specifically, the current positioning data of the battery is compared with the regional range of the charging control area. If the current positioning data is within the regional range of the charging control area, it is determined that the current battery has entered the charging control area. If the current positioning data is outside the regional range of the charging control area, it is determined that the current battery has not entered the charging control area, that is, the current battery is in the non-charging control area.

[0070] In one possible implementation, when determining whether the current positioning data is within the regional scope of the charging control area, the regional scope data of the charging control area can be obtained, and the maximum longitude value, minimum longitude value, maximum latitude value and minimum latitude value corresponding to the charging control area can be calculated based on the regional scope data of the charging control area. When the minimum longitude value ≤ the longitude value of the previous positioning data ≤ the maximum longitude value, and the minimum latitude value ≤ the latitude value of the previous positioning data ≤ the maximum latitude value, it can be determined that the current positioning data is within the regional scope of the charging control area; otherwise, it is determined that the current positioning data is outside the regional scope of the charging control area.

[0071] It should be noted here that in some cases, the current positioning data may be offset. In order to accurately determine whether the battery has entered the charging control area at the current moment, the positioning data of the battery at adjacent moments can be combined to determine whether the battery has entered the charging control area at the current moment. Specifically, first refer to the above method to determine whether the current positioning data of the battery is located in the charging control area. When it is determined that the current positioning data of the battery is within the range of the charging control area, continue to obtain the positioning data corresponding to the previous moment adjacent to the current moment, recorded as the previous positioning data, and determine whether the previous positioning data is within the range of the charging control area. When the previous positioning data is also within the range of the same charging control area, it is determined that the battery has entered the charging control area at the current moment.

[0072] If it is determined that the battery is located in the charging control area, step S1300 is executed. If it is determined that the battery is located in the non-charging control area, the operation of obtaining the positioning data transmitted by the battery next time is continued.

[0073] S1300, when it is determined that the battery is located in a charging control area, determine the area type of the current location of the battery according to the current positioning data, wherein the area type is at least one of a safe area and a prohibited area. The safe area is used to represent a safe area where charging can be performed, and the prohibited area represents an area where there are potential charging safety hazards, such as the internal area of ​​a building in a residential area.

[0074] In one possible implementation, when determining the area type of the current location of the battery based on the current positioning data, the positioning type is implemented based on the current positioning data, wherein the current positioning data sent back by the battery includes the positioning type, and the positioning type includes at least one of LBS positioning and GPS positioning.

[0075] It should be noted here that since the positioning accuracy of LBS positioning is relatively low, therefore, when the positioning type of the current positioning data is LBS positioning, it is necessary to combine the trajectory data with the current positioning data as the end point to determine the area type of the current location of the battery, which specifically includes the following steps:

[0076] First, the trajectory data within a set time period with the current positioning data as the end point is obtained. Specifically, the set time period can be the time period from when the battery enters the charging control area to when the current positioning data is obtained.

[0077] Second, based on the trajectory data, determine whether the battery has entered a pre-set prohibited area: if it is determined that the battery has entered the prohibited area, determine the area type at the current location of the battery to be a prohibited area; if it is determined that the battery has not entered the prohibited area, determine the area type at the current location of the battery to be a safe area.

[0078] It should be noted here that after the charging control area is constructed, the prohibited area within the charging control area will also be constructed at the same time. Specifically, the area range of each prohibited area within the charging control area is outlined in the map data, and the area in the map data covered within the area range of each prohibited area outlined is used as the prohibited area within the charging control area. Among them, the construction process of each prohibited area refers to the construction structure of the charging control area, which will not be repeated here. For example, when the target area is area A, the charging control area is defined as the B residential area within area A, and the prohibited area is defined as the interior of the building within the B residential area, after the B residential area within area A is constructed as the charging control area, the area range of each building within the residential area will also be outlined in the charging control area, and the area in the map data covered within the area range of each building will be used as each prohibited area within the charging control area. After each prohibited area is constructed, the area range of each prohibited area will also be recorded, so that it can be determined whether the battery has entered the prohibited area based on the area range of each prohibited area.

[0079] When judging whether the battery has entered the prohibited area based on the battery's trajectory data, it is possible to judge whether the battery has a tendency to enter any prohibited area based on the trajectory data. When there is a tendency to enter any prohibited area, it is further judged whether the current position data is within the area range of the prohibited area to be entered (see the steps for judging whether the battery has entered the charging control area for details, which will not be repeated here). If so, it can be judged that the battery has entered the pre-set prohibited area.

[0080] It should be noted here that the battery collects positioning data at a preset frequency. Under the LBS positioning mode, once the user enters the building, the current position data may not be obtained, and the current position data will be lost. In this case, the most recently obtained position data will be used as the end point of the trajectory data. When it is judged that the battery has a tendency to enter any prohibited area based on the trajectory data, the minimum distance between the most recently obtained position data and the area range of the prohibited area to be entered will continue to be calculated. When the calculated minimum distance is less than or equal to the preset distance threshold, it is determined that the battery has entered the prohibited area.

[0081] Since the positioning accuracy of GPS positioning is relatively high, therefore, when the positioning type of the current positioning data is GPS positioning, it is possible to directly determine whether the battery has entered a pre-set prohibited area based on the current positioning data of the battery. Specifically, it is determined whether the current positioning data of the battery is within the area range of any constructed prohibited area (refer to the determination step of whether the battery has entered the charging control area for details, which will not be repeated here). When it is within the area range of any prohibited area, it can be determined that the battery has entered the prohibited area. In the case where it is determined that the battery has entered the prohibited area, the area type at the current position of the battery is determined to be a prohibited area. In the case where it is determined that the battery has not entered the prohibited area, the area type at the current position of the battery is determined to be a safe area. If the current position data is lost, the minimum distance between the most recently acquired position data and the area range of the nearest prohibited area can be calculated. When the calculated minimum distance is less than or equal to the preset distance threshold, it is determined that the battery has entered the prohibited area.

[0082] It should be noted here that in the actual charging process, there is a situation that after the user brings the battery into the building, the battery is hung outside the window for charging. This situation also poses a safety hazard to charging. Therefore, in a possible implementation method, when it is determined that the battery has not entered the prohibited area, the following steps are also included:

[0083] First, obtain the elevation data in the current positioning data.

[0084] Second, determine whether the elevation data is less than or equal to the average elevation within the charging control area.

[0085] Third, when the elevation is less than or equal to the average elevation, the area type at the current location of the battery is determined to be a safe area. When the elevation data is greater than the average elevation, the area type at the current location of the battery is determined to be a prohibited area.

[0086] That is to say, after the battery is no longer in the prohibited area, in order to prevent the user from hanging it outside the window for charging, the elevation of the battery location is still determined. When the elevation data at the location is greater than the average elevation in the control area, it can be determined that the battery is hanging outside the building window for charging. Therefore, the area type of the current location of the battery will also be determined as a prohibited area.

[0087] It should be noted here that when the positioning type of the current positioning data is GPS positioning, the number of satellites that generate the current positioning data will also be determined. When the number of satellites is greater than or equal to the preset number, the elevation will be determined. This can ensure the accuracy of the elevation determination, and further ensure the accuracy of the area type determination at the current location of the battery. Among them, the preset number can be set to 4, that is, when the number of satellites that generate the current positioning data is greater than or equal to 4, the relevant elevation determination will be performed.

[0088] In a possible implementation, in order to improve the accuracy of determining whether the battery has entered a prohibited area, a charging control area identifier will be sent to the battery after it is determined that the battery has entered a charging control area. After receiving the charging control area identifier, the battery will increase the frequency of collecting and uploading positioning data, thereby being able to more timely and accurately determine whether the battery has entered a prohibited area. In other words, before the battery enters the charging control area, the positioning data is collected and uploaded at a first preset collection frequency, and after entering the charging control area, the positioning data is collected and uploaded at a second preset collection frequency. The second preset collection frequency is greater than the first preset collection frequency.

[0089] After determining the area type of the current location of the battery, step S1400 can be executed to send the area type to the cloud box so that the cloud box can control the battery charging according to the area type. The cloud box can be a device independent of the battery or a functional module built into the battery, which is not specifically limited here.

[0090] In the case where the cloud box is a plug-in component independent of the battery, the cloud box is provided with two terminals, namely, a first terminal and a second terminal, wherein the first terminal is suitable for electrically connecting to a charging power source, the second terminal is suitable for electrically connecting to a power access terminal of the battery (i.e., one end electrically connected to a charging power source), and the battery's electric vehicle access terminal is suitable for electrically connecting to a charging interface on an electric vehicle (i.e., a charging interface provided on an electric vehicle), so that when charging an electric vehicle, a charging circuit between a power source-cloud box-battery-electric vehicle can be established. At the same time, if Figure 3 As shown, the cloud box is also connected to the positioning module inside the battery and the cloud server in communication, so that the positioning module in the battery can send the current positioning data collected in real time to the cloud box, and upload it to the cloud server through the cloud box. After the cloud server determines the area type of the current location of the battery based on the current positioning data, it can send the area type of the current location to the cloud box. It should be noted here that after the cloud box receives the current positioning data sent by the battery positioning module, it sends the current positioning data and the identity identifier that uniquely identifies the identity of a cloud box to the cloud server. In this way, the cloud server can associate the current location data from a battery and the area type at the current location determined according to the current location data through the identity identifier of the cloud box. In this way, after calculating the area type of the current location of the battery, the area type can be sent to the corresponding cloud box based on the identity identifier associated with the area type, so that the cloud box can control the charging of the battery electrically connected to it according to the received area type.

[0091] When the cloud box is a functional module built into the battery, such as Figure 4As shown, the cloud box is connected to the positioning module inside the battery and the cloud server outside the battery to upload the current positioning data and receive the area type of the current location of the battery. The specific process is described in the above text and will not be repeated here. At the same time, the cloud box is also electrically connected to the charging control circuit inside the battery to realize the charging control of the battery.

[0092] In a possible implementation, after the area type is sent to the cloud box, the cloud box will perform the following operations to implement charging control of the battery electrically connected thereto:

[0093] First, obtain the area type of the current location of the battery sent by the cloud server, where the area type includes at least one of a safe area and a prohibited area.

[0094] Second, according to the area type, a charging control signal for the battery at the current location is generated.

[0095] In a possible implementation, the area type is a prohibited area. When generating a charging control signal of a battery at a current position according to the area type, the following steps may be included:

[0096] Determine whether there is a charging current; if it is determined that there is a charging current, generate a first charging control signal for disconnecting the charging control circuit, and disconnect the charging control circuit in response to the first charging control signal.

[0097] In a possible implementation, the battery charging control circuit can be as follows: Figure 5 As shown, Figure 5 As shown, the charging control circuit includes a switch driving module, and the switch driving module includes a charging control terminal (i.e. Figure 5 One end of the output EN-CHGMOS in the charging control module), when it is determined that there is a charging current, a first charging control signal for disconnecting the charging control circuit will be generated, wherein the first charging control signal is a low level signal. In this way, when the first charging control signal is applied to the charging control end, the two transistors Q1 and Q2 in the switch driving module will be disconnected, thereby achieving the purpose of disconnecting the charging control circuit. At this time, the G poles of the charging MOSs such as Q6, Q7, Q8, Q9, Q10, and Q11 in the protection switch module in the charging control circuit lose the 12V driving voltage and stop charging.

[0098] In a possible implementation, the area type is a safety area, and when generating a charging control signal of the battery at the current position according to the area type, the method includes:

[0099] A second charging control signal for starting the charging control circuit is generated, and the charging control circuit is started in response to the second charging control signal.

[0100] In the battery charging control circuit such as Figure 5 In the illustrated embodiment, when it is determined that there is a charging current, a second charging control signal for turning on the charging control circuit will be generated, wherein the second charging control signal is a high-level signal. Thus, when the second charging control signal is applied to the charging control terminal, the two transistors Q1 and Q2 in the switch driving module will be turned on, thereby achieving the purpose of turning on the charging control circuit. At this time, when a 12V driving voltage is connected, the G poles of the charging MOS such as Q6, Q7, Q8, Q9, Q10, Q11 in the protection switch module in the charging control circuit can regain the 12V driving voltage, thereby performing a charging operation.

[0101] Third, the charging control circuit of the battery is charged and controlled according to the charging control signal. Please refer to the relevant description of the second step for details, which will not be repeated here.

[0102] The present disclosure provides a battery charging control method, including: obtaining the current positioning data of the battery; judging whether the battery is in a pre-defined charging control area according to the current positioning data; in the case of judging that the battery is in the charging control area, determining the area type of the current position of the battery according to the current positioning data, wherein the area type is at least one of a safe area and a prohibited area; sending the area type to a cloud box, so that the cloud box performs charging control on the battery according to the area type. The charging control method of this embodiment can determine whether the current position of the battery is a safe area or a prohibited area according to the current position data of the battery on the electric vehicle, and then implement different charging control on the electric vehicle battery according to whether the current position of the battery is a safe area or a prohibited area, thereby effectively preventing the electric vehicle from charging in a prohibited area.

[0103] It should be noted that the method disclosed herein can be performed as follows: Figure 4 The charging control integrated system shown is implemented as follows: Figure 4 As shown, the integrated battery charging management and control system 200 includes: a cloud server 210 (i.e., the battery charging management and control system in the system claims) and a battery 220 suitable for an electric vehicle, wherein the battery 220 includes a cloud box 221, a positioning module 222, and a charging control circuit 223.
