[0089] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0090] Figure 1This is a flowchart of a battery management method provided by an exemplary embodiment of the present invention. The management method is applied to a battery management platform. The battery management platform can be deployed on a server of a battery swap station or on another server. Figure 1 , the management method comprises the following steps:

[0091] Step 101: In response to a battery swap request of a battery swap vehicle, obtain vehicle data of the battery swap vehicle.

[0092] Vehicle data is data that can identify a vehicle and is provided by the on-board terminal of the battery-swap vehicle. It may include but is not limited to at least one of the following parameters: license plate information, vehicle identification code (VIN code), user identity information of the vehicle, etc.

[0093] Step 102: extract battery data that matches the replaced battery of the battery-swap vehicle from the database.

[0094] The database stores multiple sets of vehicle data and battery data in an associated manner. Battery data includes attribute data provided by the battery management platform and battery swap data provided by the battery swap station. Attribute data includes at least one of the following parameters: battery number, rated capacity, rated voltage, source information, etc. Battery swap data includes at least one of the following parameters: number of battery swaps, time of last battery swap, frequency of battery swap, etc.

[0095] The database is a shared database of the battery management platform and the battery swap station, and the data in the database is jointly maintained by the battery management platform and the battery swap station. For each battery swap, the battery swap station will provide battery swap data so that the battery swap data is stored in association with the vehicle data. The use of a shared database facilitates the management and maintenance of the battery's full life cycle data. The battery data extracted in step 102 is used to determine the battery status of the replaced battery, and the battery status can be accurately determined based on the battery's full life cycle data.

[0096] The prerequisite for accurately determining the battery status is to obtain accurate battery data of the replaced battery. The replaced battery is removed from the battery swapping vehicle. The battery data of the replaced battery can be accurately extracted from the database through the vehicle data of the battery swapping vehicle and used as the data basis for determining the battery status in step 103.

[0097] In one embodiment, the battery data is extracted from the database through the attribute data of the replaced battery. Specifically, the attribute data of the replaced battery is obtained, and it is determined whether there is battery data matching the attribute data of the replaced battery in the database. If the judgment result is yes, it means that the replaced battery has been registered for network access, then the battery data matching the attribute data of the replaced battery is extracted from the database and used as the battery data matching the replaced battery, and it is used as the data basis for determining the battery status in step 103. If the judgment result is no, it means that the replaced battery has not been registered for network access, that is, there is no battery data matching the attribute data in the database, and a prompt message can be generated and / or the attribute data of the replaced battery can be associated with the vehicle data of the battery replacement vehicle and stored as the data basis for determining the battery status next time. The specific implementation process of associating and storing attribute data and vehicle data is described below. By automatically identifying new users or users who have been connected to the network, the network access operation can be completed quickly, efficiently and accurately after identifying the new user, and the vehicle data and battery data are uploaded to the cloud database for associated storage and unified management.

[0098] In order to further improve the accuracy of battery data acquisition, in one embodiment, battery data is extracted from a database in combination with the attribute data of the replaced battery. Specifically, the attribute data of the replaced battery is obtained, and it is determined whether there is battery data in the database that matches both the attribute data of the replaced battery and the vehicle data. If the judgment result is yes, battery data that matches both the attribute data and the vehicle data of the replaced battery is extracted from the database and used as the battery data that matches the replaced battery, and is used as the data basis for determining the battery status in step 103. If the judgment result is no, that is, there is no battery data that matches both the attribute data and the vehicle data in the database, a prompt message may be generated and / or the attribute data of the replaced battery may be associated with the vehicle data of the battery replacement vehicle and stored as the data basis for determining the battery status next time. The specific implementation process of associating and storing attribute data and vehicle data is described below.

[0099] In one embodiment, when authorization is obtained or it is determined that the replaced battery meets the network access conditions, the attribute data of the replaced battery is associated with the vehicle data of the battery replacement vehicle and stored. The battery with the associated attribute data is registered for network access. The network access conditions can be set according to actual needs, for example, the battery source is normal.

[0100] In one embodiment, the acquired attribute data of the replaced battery may be transmitted by the electronic device through a wired or wireless signal, and the attribute data in the electronic device is manually input; the acquired attribute data of the replaced battery may also be obtained by performing image recognition on a battery image of the replaced battery, and the battery image of the battery is obtained by taking a photo during the battery replacement process.

[0101] The electronic devices may include but are not limited to mobile phones, computers, and tablet computers.

[0102] Step 103: Analyze the battery data to determine the battery status of the replaced battery.

[0103] In one embodiment, the battery status is determined by the correspondence between the preset parameter value range and the battery status. Specifically, the parameter value range within which the parameter value of each battery parameter included in the battery data falls is determined, and the battery status of the replaced battery is determined based on the correspondence between the parameter value range and the battery status. The battery status is determined in this way, with a small amount of calculation and easy implementation.

[0104] For example, assume that the correspondence between the parameter value range and the battery state is: the parameter value range [a1, a2] of battery parameter a corresponds to battery state A, the parameter value range [b1, b2] of battery parameter b corresponds to battery state B, the parameter value range [c1, c2] of battery parameter c and the parameter value range [a3, a4] of battery parameter a correspond to battery state C; when the parameter value of battery parameter a contained in the battery data falls within the parameter value range [a1, a2], the battery state is determined to be battery state A; when the parameter value of battery parameter a contained in the battery data falls within the parameter value range [a3, a4] and the parameter value of battery parameter c falls within the parameter value range [c1, c2], the battery state is determined to be battery state C.

[0105] The correspondence between the parameter value range and the battery state can be determined by analyzing historical battery data. Each battery state can be determined based on one battery parameter or multiple battery parameters, which is not particularly limited in the embodiment of the present invention.

[0106] In one embodiment, the parameter values ​​of the parameters included in the battery data are fitted, and the battery state of the replaced battery is determined based on the corresponding relationship between the parameter fitting result and the battery state. Compared with the method of using the parameter value range, the battery state is determined with higher accuracy in this way. The parameter fitting result can be represented by a function or a curve, which is not particularly limited in the embodiment of the present invention.

[0107] In one embodiment, the parameter values ​​of each battery parameter included in the battery data are input into a pre-trained state determination model, so that the state determination model determines the battery state of the replaced battery. The state determination model is obtained by training a neural network with a large number of training samples. The specific training process is described in the related technology and will not be repeated here. The state determination model can accurately determine the battery state based on the input battery data.

[0108] The above-mentioned methods for determining the battery status can also be used in combination, that is, the battery status is determined according to multiple methods. When the battery status determined by each method is the same, the battery status is determined as the final status of the replaced battery; if the battery status determined by each method is not completely the same, the battery status with the largest number of results can be selected as the final status of the replaced battery. By using multiple methods for determining the battery status or using them in combination, the battery status can be accurately judged, and the accuracy and effectiveness of battery management can be improved.

[0109] In the embodiment of the present invention, the advantages of the battery replacement and energy replenishment mode are fully utilized, and the battery status is detected once each battery replacement. Through high-frequency detection, corresponding measures are taken in time according to the battery status, which greatly improves the timeliness of battery management.

[0110] Step 104: Execute a preset operation matching the battery status on the replaced battery.

[0111] In one embodiment, a correspondence between the battery status and the preset operation is preset, and in step 104, a preset operation matching the battery status of the replaced battery is determined and executed according to the correspondence.

[0112] The battery status may include but is not limited to at least one of the following: network switching request status, network exit status, fault retirement status, user request network exit status, battery gradient utilization retirement status, maintenance waiting status, abnormal status.

[0113] The preset operations matching the network switching request status include: executing a network switching operation and / or generating a network switching reminder;

[0114] The preset operations matching the network exit status include: executing the network exit operation and / or generating a network exit reminder;

[0115] Preset operations that match the fault retirement status include: executing a fault retirement operation and / or generating a fault retirement reminder;

[0116] The preset operation matching the network exit status requested by the user includes: executing the network exit operation and / or generating a network exit reminder;

[0117] The preset operations matching the battery gradient utilization retirement state include: executing a gradient utilization retirement operation and / or generating a gradient utilization retirement reminder;

[0118] The preset operations matching the state to be maintained include: executing battery maintenance operations and / or generating elevator battery maintenance reminders;

[0119] The preset operations matching the abnormal state include: generating a battery abnormality reminder.

[0120] According to the different battery conditions, the replaced batteries are treated in a targeted manner, ensuring safe and efficient use of the batteries throughout their life cycle and giving full play to the value of each battery.

[0121] In one embodiment, after performing a preset operation that matches the battery status on the replaced battery, the battery data stored in the database is also updated based on the execution result of the preset operation. When the preset operation of the battery is completed, the battery status is updated each time the battery is replaced to ensure that the battery data matches the battery status as much as possible, so that the battery status can be accurately determined at the next battery replacement.

[0122] For example, the maintenance status is determined according to the number of times the battery has been replaced. After the battery maintenance operation is performed on the replaced battery, the number of times the replaced battery has been replaced in the database is reset to re-count the number of times the battery has been replaced.

[0123] In one embodiment, the battery status and battery data are stored in association so that the battery management platform and the battery replacement platform can query the battery status in real time, ensuring the historical traceability of the data.

[0124] In an embodiment of the present invention, the battery status of a replaced battery is determined based on the attribute data provided by the battery management platform and the battery replacement data provided by the battery replacement station, and based on the battery status, operations matching the battery status are performed on the replaced battery, thereby achieving automated and efficient management of the battery throughout its life cycle.

[0125] Figure 2 A flowchart of another battery management method provided by an exemplary embodiment of the present invention, the management method is applied to a battery management platform, the battery management platform can be deployed on a server of a battery swap station, or a separate server can be set up to deploy the battery management platform, or a separate server can be set up to implement it; see Figure 2 , the management method comprises the following steps:

[0126] Step 201: In response to a battery swap request of a vehicle, obtain vehicle data of the battery swap vehicle.

[0127] Step 202: extract battery data that matches the replaced battery of the battery-swap vehicle from the database.

[0128] The specific implementation of step 201 and step 202 is similar to the specific implementation of step 101 and step 102. The specific implementation process refers to the description of step 101 and step 102, which will not be repeated here.

[0129] Step 203: Determine whether replacing the battery meets maintenance conditions based on the battery data.

[0130] The battery data includes at least one of the following parameters: number of battery replacements and time of last battery replacement.

[0131] The maintenance conditions can be set according to the actual situation. For example, the maintenance conditions include at least one of the following: the number of battery replacements is greater than the number threshold; the time from the current moment to the last battery replacement is greater than the time threshold. Among them, the number threshold and the time threshold are set according to the actual situation. For example, the number threshold is set to 95 and the time threshold is set to 6 months.

[0132] By combining the historical data of the battery, the number of battery replacements and / or the time interval between battery replacements are used as the basis for battery maintenance, among which a certain number of battery replacements serves as the cycle basis for battery maintenance, and the judgment of the battery replacement time interval serves as a supplementary basis. The above two battery maintenance bases work together to ensure the standardization and timeliness of battery maintenance.

[0133] Step 204: if it is determined that the replacement battery meets the maintenance conditions, generate a maintenance reminder for the replaced battery.

[0134] The maintenance reminder is used to remind the operation and maintenance personnel to perform maintenance on the replaced battery.

[0135] In one embodiment, when the battery maintenance is completed, the maintenance data of the replaced battery is obtained, and the battery data in the database is updated according to the maintenance data. When the battery maintenance is completed, the battery status is updated, and the cloud database is used to associate and store the battery status information and manage it in a unified manner, which is convenient for battery fault recording, battery tracing, etc., and provides a data basis for battery management.

[0136] For example, the maintenance status is determined according to the number of times the battery has been replaced. After the battery maintenance operation is performed on the replaced battery, the number of times the replaced battery has been replaced in the database is reset to re-count the number of times the battery has been replaced.

[0137] In one embodiment, when the replaced battery does not meet the maintenance conditions and the replaced battery is in normal condition, the battery data in the database is updated according to the battery replacement operation of the replaced battery by the battery replacement station, for example, the number of battery replacements is increased by 1.

[0138] In the above embodiment, the database associates and stores vehicle data and battery data, wherein the battery data can be stored in the database when the battery is newly connected to the network, or can be stored in the database when the battery-swapping vehicle determines that the battery data of the replaced battery does not exist in the database when requesting a battery swap.

[0139] In the embodiment of the present invention, whether the replaced battery meets the maintenance conditions is determined based on the attribute data provided by the battery management platform and the battery replacement data provided by the battery replacement station. The battery that needs maintenance can be automatically discovered and maintained in time to ensure the health of the battery.

[0140] Furthermore, the advantages of the battery swapping and energy replenishing mode are fully utilized. The battery status is tested every time the battery is swapped. Through high-frequency testing, comprehensive off-vehicle maintenance is carried out on the battery in a timely manner according to the battery status, which greatly improves the timeliness of battery maintenance. The characteristics of the battery swapping mode fundamentally overcome the greater risks caused by untimely battery maintenance and repairs due to negligence of electric vehicle users.

[0141] The following introduces the implementation process of associating and storing vehicle data and battery data in a battery swap scenario for a battery swap vehicle.

[0142] Figure 3 A flowchart of a method for associating and storing vehicle data and battery data provided by an exemplary embodiment of the present invention, the battery storage method comprises the following steps:

[0143] Step 301: Obtain first attribute data of a replaced battery identified by the battery compartment when the replaced battery is placed in the battery compartment.

[0144] The first attribute data includes at least one of the following parameters: battery number, rated capacity, rated voltage, source information, etc.

[0145] In one embodiment, the first attribute data is obtained by the battery compartment through image recognition of a battery image of a replaced battery. The battery image is obtained by taking a picture of the battery image by a camera in the battery compartment.

[0146] In one embodiment, the first attribute data is obtained by transmitting a wireless signal. Specifically, the electronic device obtains the first attribute data of the replaced battery and transmits it to the battery management platform via a wireless signal.

[0147] The electronic device may be, but is not limited to, a mobile phone, a computer, a tablet computer, etc.

[0148] Step 302: Obtain the entered second attribute data of the replaced battery.

[0149] The second attribute data includes at least one of the following parameters: battery number, rated capacity, rated voltage, source information, etc.

[0150] In one embodiment, the second attribute data is entered via an electronic device.

[0151] Step 303: Determine whether the parameter value of each parameter included in the second attribute data matches the parameter value of the corresponding parameter included in the first attribute data.

[0152] When the judgment result in step 303 is yes, step 304 is executed; when the judgment result in step 303 is no, step 305 is executed to generate a data mismatch prompt to remind the operation and maintenance personnel to check the data.

[0153] For example, if both the first attribute data and the second attribute data include a battery code and source information, in step 303, it is determined whether the battery code included in the second attribute data matches the battery code included in the first attribute data, and whether the source information included in the second attribute data matches the source information included in the first attribute data, and if both the battery code and the source information match, step 304 is executed. If only one parameter of the battery code and the source information does not match, a data mismatch prompt is generated.

[0154] Step 304: If the judgment result is yes, the first attribute data or the second attribute data is used as the attribute data of the replaced battery and is stored in association with the vehicle data of the battery-replacement vehicle.

[0155] In the embodiment of the present invention, during the network access operation for a new user, the attribute data of the network access battery is verified to prevent problems such as network access information errors and ensure that the associated stored vehicle data and battery data are accurate and valid.

[0156] In one embodiment, the method further includes: determining whether there is duplicate attribute data of the replaced battery in the database. If the determination result is yes, deleting the duplicate attribute data and / or issuing a data duplication reminder. By identifying duplicate battery attribute data in the database, it is possible to prevent users from misoperating and causing the battery to access the network multiple times, maintain the accuracy of battery management data, prevent battery management errors, and improve the stability of the battery management system.

[0157] The timing for determining whether there is repeated attribute data of replacing the battery in the database may be performed periodically or upon application, which is not particularly limited in the embodiment of the present invention.

[0158] Regarding the storage of attribute data, the specific implementation method in the scenario where the battery is newly connected to the network is similar to the specific implementation method in the above-mentioned battery replacement scenario. The difference is that in the scenario where the new battery is newly connected to the network, since the new battery has not yet been attributed as an asset, that is, there is no vehicle data associated with it, the attribute data of the new battery is directly stored in step 304, and there is no need to associate and store the attribute data and vehicle data.

[0159] In one embodiment, the method further includes: in response to a battery attribution request, determining whether there is battery data in the database that has not yet been associated with the vehicle data, generally the battery data of a new battery. If the result of the determination is yes, the vehicle data carried in the battery attribution request and the battery data that has not yet been associated are stored in an associated manner to achieve asset attribution. Based on the application of the new user, the associated storage of the vehicle data and the battery data is completed, and the network access operation can be completed quickly, efficiently and accurately, and the vehicle data and the battery data are uploaded to the cloud database for associated storage and unified management.
