Detailed Implementation

[0018] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with one or more embodiments of the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of one or more embodiments of the present invention as detailed in the appended claims.

[0019] It should be noted that the steps of the corresponding methods in other embodiments are not necessarily performed in the order shown and described in this invention. In some other embodiments, the methods may include more or fewer steps than those described in this invention. Furthermore, a single step described in this invention may be broken down into multiple steps in other embodiments; and multiple steps described in this invention may be combined into a single step in other embodiments.

[0020] The present invention aims to provide a charging control method for improving the charging speed of a charging terminal.

[0021] The charging control method of the present invention will now be described in detail with reference to the accompanying drawings.

[0022] Please refer to Figure 1 , Figure 1 A flowchart of a charging control method provided as an exemplary embodiment of the present invention is shown. This charging control method is applied to a charging terminal, wherein at least two different charging parameters are deployed in the charging terminal. The method includes: Step 110: Obtain the transmission power of the power transmission equipment; Step 120: Determine a target charging parameter that matches the transmission power from the at least two different charging parameters; Step 130: Adjust the maximum charging power of the charging terminal during the charging process according to the target charging parameters, so that the charging terminal charges based on the maximum charging power.

[0023] In this invention, the charging terminal may include a vehicle equipped with a power battery, such as a pure electric vehicle, a range-extended vehicle, or a plug-in hybrid vehicle, etc.; correspondingly, the power transmission equipment may include charging piles in charging stations, home charging piles, mobile charging equipment, etc.

[0024] In addition, the charging terminal may also include an electric bicycle, and the power transmission equipment may be a device for charging the electric bicycle.

[0025] Through the above embodiments, since at least two different charging speed parameters are deployed within the charging terminal, a target charging parameter adapted to the power transmission capacity of the power transmission equipment can be matched. This allows the charging terminal to dynamically adjust its maximum charging power based on the target charging parameters. On one hand, no additional development and adaptation of proprietary protocols is required, and the switching of charging parameters can be performed automatically, maximizing the compatibility between the charging terminal and the power transmission equipment. On the other hand, the charging terminal can always charge at its maximum charging power, thus improving the charging speed.

[0026] In one exemplary embodiment, the charging parameters include a charging power mapping table.

[0027] Taking a vehicle equipped with a power battery as an example, a charging power mapping table is stored in the Battery Management System (BMS) before the vehicle leaves the factory. The charging power mapping table is a two-dimensional lookup table model based on battery state parameters (such as state of charge (SOC), temperature, etc.) to determine parameters such as the maximum allowable power or current during the charging process in real time. Its function is to dynamically adjust the maximum charging power of the charging terminal through a predefined mapping relationship to ensure that the battery of the charging terminal is always in a safe state during the charging process.

[0028] In related technologies, because charging terminals use the same charging power mapping table when using different power transmission equipment, even if the power transmission equipment has a higher charging speed, the full power transmission capacity of that equipment cannot be obtained due to the limitations of the charging power mapping table. This prevents the charging terminal from effectively increasing its charging speed, resulting in a waste of the power transmission capacity of the power transmission equipment.

[0029] To this end, the present invention deploys at least two different charging power mapping tables in the charging terminal, wherein the charging power in the different charging power mapping tables does not overlap, and each charging power mapping table includes a minimum charging power and a maximum charging power.

[0030] This allows for the matching of a target charging power mapping table from at least two different charging power mapping tables, based on the actual situation of the power transmission equipment. This enables the matching of the target charging power mapping table from the charging power mapping table currently used by the charging terminal.

[0031] For example, step 120 above, such as Figure 2 The diagram may include: Step 121: For each charging power mapping table, calculate whether the transmission power is within the interval formed by the lowest charging power and the highest charging power in the current charging power mapping table; Step 122: If yes, determine that the current charging power mapping table is the target charging power mapping table that matches the power transmission equipment.

[0032] Taking vehicle charging stations as an example, different charging stations now offer charging piles with different charging speeds. Some charging piles with slower charging speeds have a power output of 60 kilowatts, some with faster charging speeds have a power output of 160 kilowatts, and some with even faster charging speeds have a power output of 350 kilowatts, and so on. These are just some examples of power outputs and do not represent the only possible power outputs.

[0033] In this invention, for charging piles with different charging speeds, at least two different charging power mapping tables can be built into the vehicle.

[0034] The following is based on Figure 3 The first and second charging power mapping tables shown in the figure are used as examples for illustration: The first charging power mapping table can cover a power range of [40 kW, 80 kW], which is compatible with the power transmission equipment in the early charging stations; The second charging power mapping table can cover a power range of [120 kW, 400 kW], which can be adapted to more advanced power transmission equipment in newly built charging stations.

[0035] Thus, for any charging station, only the transmission power of that charging station needs to be obtained to determine the target charging power mapping table that matches that transmission power. For example, if the transmission power of the charging station is 60 kW, since it falls within the power range of the first charging power mapping table, the first charging power mapping table can be determined as the target charging power mapping table. During the charging process, based on real-time battery state parameters (such as state of charge (SOC), temperature, etc.), the maximum charging power mapped to that battery state parameter is queried from the target charging power mapping table (since the target charging power mapping table is the first charging power mapping table at this time, the maximum charging power is limited to the range of [40 kW, 80 kW]). Based on this, the vehicle can dynamically adjust the current charging power to this maximum charging power to ensure that the vehicle's battery is always in a safe state during the charging process.

[0036] If the charging pile's transmission power is 160 kW, since it falls within the power range of the second charging power mapping table, the second charging power mapping table can be used as the target charging power mapping table. During charging, based on real-time battery state parameters, the maximum charging power mapped to that battery state parameter is queried from the target charging power mapping table (since the target charging power mapping table is the second charging power mapping table at this time, the maximum charging power is limited to the range of [120 kW, 400 kW]). Based on this, the vehicle can dynamically adjust the current charging power to this maximum charging power, ensuring that the vehicle's battery remains in a safe state during charging.

[0037] In practical applications, there may be situations where the transmission power of the power transmission equipment cannot match the target charging power mapping table. For example, if the transmission power of the charging pile is 100 kilowatts, it is not within the power range of the first and second charging power mapping tables mentioned above. In this case, a backward compatibility strategy can be adopted, using the first charging power mapping table with the maximum power closest to 100 kilowatts as the target charging power mapping table.

[0038] For existing vehicles that existed before the development or mass production of more advanced technologies used in more advanced power transmission equipment, their factory-installed charging power mapping table is typically adapted to the power transmission equipment in the earlier charging stations. Therefore, even if such existing vehicles enter newly built charging stations to use more advanced power transmission equipment, the first charging power mapping table limits the maximum transmission power to 80 kW, restricting the power transmission equipment to only 80 kW, which significantly limits the charging speed. However, the embodiment proposed in this invention adds a second charging power mapping table to the existing vehicle's first charging power mapping table. This allows the second charging power mapping table to be used when charging with more advanced power transmission equipment, enabling the equipment to transmit at full load, for example, 350 kW, greatly improving the charging speed.

[0039] Since the second charging power mapping table is just a mapping table, existing vehicles only need to download it to their battery management system via Over-The-Air (OTA) technology. No additional development and adaptation of proprietary protocols is required, resulting in lower improvement costs and a significant increase in charging speed.

[0040] In one exemplary embodiment, such as Figure 2 As shown, step 110, determining the transmission power of the transmission equipment, may include: Step 111: In response to the successful connection between the charging terminal and the power transmission equipment, receive a communication message sent by the power transmission equipment after the successful connection; wherein, the communication message carries the power transmission power of the power transmission equipment; Step 112: Obtain the power transmission power of the power transmission equipment from the communication message.

[0041] In practical applications, determining the transmission power of power transmission equipment can be achieved by utilizing the necessary operations during the charging process, namely connecting the charging terminal and the power transmission equipment. After successful connection, the charging terminal and the power transmission equipment need to prepare for charging (this process is usually called "handshake"), such as exchanging information and performing charging safety verification. During the handshake, the power transmission equipment can send its own transmission power to the charging terminal along with the communication message.

[0042] In this embodiment, since the physical connection between the charging terminal and the power transmission equipment is a necessary operation in the charging process, and the handshake after the connection is successful is also a necessary process in the charging process, the power transmission is transmitted to the charging terminal by means of communication messages without the need for additional operation steps, and the modification cost is low.

[0043] In addition, the transmission power provided by the transmission equipment itself is more accurate and reliable than other methods (such as manually entering the transmission power after the user checks the nameplate of the transmission equipment).

[0044] It is understandable that, in addition to automatically matching the target charging power mapping table with the power transmitted through the power transmission equipment, this charging terminal also supports other methods to determine the target charging power mapping table: For example, the charging terminal allows users to manually match the target charging power mapping table to the power transmission equipment.

[0045] For example, the charging terminal can query the historical charging power mapping table of the current power transmission equipment through historical usage records. If the historical charging power mapping table is located in at least two different charging parameters, then the historical charging power mapping table can be directly used as the target charging power mapping table. To achieve this, the charging terminal's favorites service is required.

[0046] In one exemplary embodiment, such as Figure 2 As shown, when the charging terminal has a favorites service, the method may further include: Step 140: In response to the activation operation of the collection service, activate the collection service and display the collection interface; Step 150: In response to the addition operation for the power transmission equipment in the collection interface, add the relevant information of the power transmission equipment to the historical power transmission equipment in the collection service.

[0047] In this embodiment, the collection service can be a local service for maintaining the charging terminal, or a remote service obtained from a cloud server by communicating with the cloud server via Internet technology. In the former case, the historical power transmission equipment recorded by the collection service can be stored in the charging terminal's local storage device.

[0048] In the latter type of remote service, the historical power transmission equipment for which the service records are collected can be stored on a cloud server, or simultaneously on the charging terminal's local storage device and the cloud server. In the case of simultaneous storage, even if the communication connection between the charging terminal and the cloud server is interrupted, the charging terminal can still retrieve historical power transmission equipment or add new power transmission equipment based on its local storage device, and synchronize with the cloud server after communication is restored.

[0049] In this embodiment, the collection service stores historically used power transmission equipment. On the one hand, this serves as a "footprint" record for users to view at any time, thereby improving the user experience. On the other hand, it can serve as a reference for future charging, making it easier for users to know if there are any previously used power transmission equipment nearby, and thus accurately find the actual power transmission equipment. This can solve the problem of inaccurate power transmission equipment information provided by existing third parties (such as fake power transmission equipment that is shown on the map but does not actually exist).

[0050] In one exemplary embodiment, the relevant information may include target charging parameters corresponding to the power transmission equipment; like Figure 2 As shown, prior to step 130, the method may further include: Step 115: Obtain the equipment information of the power transmission equipment, and query the collection service based on the equipment information to see if the power transmission equipment exists in the historical power transmission equipment; Step 116: If it exists, read the target charging parameters corresponding to the power transmission equipment added in the collection service.

[0051] In this embodiment, the user can save the target charging parameters of the power transmission equipment used for charging after each charging. In this way, when the power transmission equipment is used again in the future, the user can directly use the target charging parameters by querying the historical power transmission equipment stored in the saved service through the equipment information of the power transmission equipment.

[0052] It should be noted that if the current power transmission equipment is not found in the historical power transmission equipment list, it means that the current power transmission equipment is being used for the first time or has not been added to the favorites service. In this case, it is necessary to match the target charging parameters through the aforementioned steps 110 and 120. That is to say, steps 115 and 116 are embodiments for matching target charging parameters that are parallel to steps 110 and 120.

[0053] The acquisition of equipment information from the power transmission equipment can refer to the aforementioned embodiment for acquiring the transmission power of the power transmission equipment. For example, it can be manually input by the user, or the equipment information can be sent to the charging terminal along with a communication message after a successful physical connection between the charging terminal and the power transmission equipment. Transmitting equipment information to the charging terminal via communication messages requires no additional operation steps, resulting in lower modification costs; furthermore, the equipment information provided by the power transmission equipment itself is more accurate and reliable.

[0054] In some embodiments, the power transmission equipment can send the aforementioned power transmission capacity and the equipment information here to the charging terminal simultaneously along with the communication message. Alternatively, the equipment information can be sent first, and the power transmission capacity can be sent only if the historical power transmission equipment cannot be found based on the equipment information.

[0055] Through the above embodiments, by utilizing the historical power transmission equipment information stored in the collection service, it can be determined whether the currently used power transmission equipment is one that has been used in the past. If so, since the charging terminal and the currently used power transmission equipment have been successfully matched with target charging parameters in the past, the target charging parameters added after the historical use of the power transmission equipment, recorded in the collection service, are directly used as the target charging parameters for this charging. This eliminates the need to repeat the target charging parameter matching process (i.e., steps 110 and 120), further shortening the time required for charging preparation while utilizing the target charging parameters to improve charging speed.

[0056] The acquisition of target charging parameters provided by the aforementioned collection service requires a successful connection between the charging terminal and the power transmission equipment. To achieve faster matching and determination of target charging parameters, the present invention also provides the following embodiments: The relevant information includes the target charging parameters corresponding to the power transmission equipment and the electronic fence range of the power transmission equipment; like Figure 2 As shown, prior to step 130, the method may further include: Step 118: The collection service continuously monitors the location information of the charging terminal, and when the location information enters the electronic fence range of any historical power transmission device, it reads the target charging parameters corresponding to the historical power transmission device added in the collection service.

[0057] Please refer to the following. Figure 4 The diagram shows an electronic fence. The collection service includes an electronic fence function that can be turned on and off by the user. For power transmission equipment used for the first time, the user can choose to enable the electronic fence function and add the electronic fence range of the power transmission equipment within the electronic fence. The electronic fence range of the power transmission equipment and the target charging parameters matched when it is used for the first time are stored together.

[0058] In this embodiment, the collection service can be a local service for the maintenance of the charging terminal. In this case, the target charging parameters corresponding to the power transmission equipment and the electronic fence range of the power transmission equipment can be stored in the local storage device of the charging terminal. This allows the system to directly call the electronic fence range in the local storage device and compare it with the location information monitored by the collection service, thus ensuring system operating efficiency.

[0059] Furthermore, the collection service can also be a remote service obtained from a cloud server via internet technology. In this case, the target charging parameters corresponding to the power transmission equipment and the electronic fence range of the power transmission equipment can be stored on the cloud server, thereby reducing the load on the local storage of the charging terminal. Of course, when the local storage of the charging terminal is sufficient, it can also be stored simultaneously on the local storage device of the charging terminal and the cloud server. In the case of simultaneous storage, even if the communication connection between the charging terminal and the cloud server is interrupted, the charging terminal can still compare the offline electronic fence range in the local storage device with the location information monitored by the collection service to avoid service unavailability.

[0060] The collection service can always run in the background of the charging terminal and continuously monitor the location information of the charging terminal. When the location information of the charging terminal enters the electronic fence range of any target power transmission device added in the past, the charging parameters currently used by the charging terminal can be switched to the target charging parameters of the target power transmission device.

[0061] It is worth mentioning that this embodiment allows for the switching of target charging parameters even before the charging terminal is connected to the power transmission equipment. Taking a new energy vehicle as an example, when a vehicle needs to charge, it typically drives towards the nearest power transmission equipment. During the vehicle's journey, the collection service can monitor the vehicle's location information and compare it with the geofence ranges of various historically added power transmission equipment. When the vehicle's location information enters the geofence range of, for example, power transmission equipment A, the vehicle's current charging parameters can be switched to the target charging parameters recorded in the collection service corresponding to power transmission equipment A.

[0062] In addition, the electronic fence range of historically added power transmission equipment located within a preset range around the vehicle can be selected for comparison based on the vehicle's location information, or the electronic fence range of the power transmission equipment closest to the location information. This can reduce the number of electronic fence ranges that need to be compared, thereby reducing the related computational load.

[0063] Through the above embodiments, by utilizing the pre-stored electronic fence range of power transmission equipment in the collection service, it is possible to predict in advance whether a charging terminal will use a certain power transmission equipment for charging, thereby switching the current charging parameters of the charging terminal to the predicted target charging parameters corresponding to the power transmission equipment in advance. Since the target charging parameters have been switched in advance, there is no need to go through the target charging parameter matching and switching process after the charging terminal is connected to the power transmission equipment, which can further improve the charging speed.

[0064] After introducing the method of an exemplary embodiment of the present invention, the apparatus, electronic device and vehicle of an exemplary embodiment of the present invention will be described next.
