The battery management platform can be deployed on the server of the battery swapping station, or another server can be set up to deploy the battery. management platform. Referring to Figure 1, the management method includes the following steps:

Step 101. Acquire vehicle data of the battery-swapping vehicle in response to the battery-swapping request of the battery-swapping vehicle.

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

Step 102, extracting battery data matching the replaced battery of the battery-swapped vehicle from the database.

The database associates and stores multiple sets of vehicle data and battery data. Battery data includes attribute data provided by the battery management platform and battery replacement data provided by the battery replacement station. The attribute data includes at least one of the following parameters: battery number, rated capacity, rated voltage, source information, and the like. The battery swap data includes at least one of the following parameters: the number of battery swaps, the last battery swap time, the battery swap frequency, and the like.

The database is a shared database of the battery management platform and the swap station, and the data in the database is jointly maintained by the battery management platform and the swap station. For each battery change, the battery change station will provide battery change data, so that the battery change data can be stored in association with the vehicle data. The shared database is used to facilitate the management and maintenance of battery life cycle data. The battery data extracted in step 102 is used to determine the battery state of the replaced battery, and the battery state can be accurately determined according to the full life cycle data of the battery.

The premise of accurately determining the battery status is to obtain accurate battery data of the replaced battery. The replaced battery is removed from the replacement vehicle, and the battery of the replaced battery can be accurately extracted from the database through the vehicle data of the replaced vehicle. The data is used as the data basis for determining the battery state in step 103.

In one embodiment, the battery data is extracted from the database by property data of the replaced battery. Specifically, the attribute data of the replaced battery is acquired, and it is judged 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 matched with the replaced battery, and it is determined in step 103 as the battery data matched with the replaced battery. Data base for battery status. If the judgment result is no, it means that the replaced battery has not been registered in the network, 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 compared with the vehicle name of the replaced vehicle. The data is associated and stored as the data basis for the next determination of the battery status. For the specific implementation process of associating stored attribute data with vehicle data, please refer to the description below. By automatically identifying new users or users who have already joined the network, after identifying new users, the network access operation can be completed quickly, efficiently and accurately, and the vehicle data and battery data are uploaded to the cloud database for associated storage and unified management.

In order to further improve the accuracy of battery data acquisition, in one embodiment, the battery data is extracted from the database in combination with the attribute data of the replaced battery. Specifically, the attribute data of the replaced battery is obtained, and it is judged whether there is battery data matching both the attribute data of the replaced battery and the vehicle data in the database. If the judgment result is yes, then extract from the database the battery data that matches the attribute data and the vehicle data of the replaced battery and use it as the battery data that matches the replaced battery, and use it as the data basis for determining the battery state 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 can be generated and/or the attribute data of the replaced battery and the vehicle data of the replaced vehicle can be associated and stored. As the data basis for the next battery status determination. For the specific implementation process of associating stored attribute data with vehicle data, please refer to the description below.

In one embodiment, when authorization is obtained or the replaced battery is determined to meet the network access conditions, the attribute data of the replaced battery is stored in association with the vehicle data of the replaced vehicle. Network registration is achieved by associating the battery with stored attribute data. Network access conditions can be set according to actual needs, for example, the battery source is normal.

In one embodiment, the acquired attribute data of the replaced battery may be transmitted by the electronic device through wired or wireless signals, and the attribute data in the electronic device is manually input; the acquired attribute data of the replaced battery may also be the The battery image of the battery is obtained by image recognition, and the battery image of the battery is obtained by shooting during the battery replacement process.

Step 103, analyze the battery data, and determine the battery status of the replaced battery.

In one embodiment, the battery state is determined through the correspondence between the preset parameter value range and the battery state. The corresponding relationship with the battery status determines the battery status of the replaced battery. Using this method to determine the state of the battery has a small amount of calculation and is easy to implement.

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

The corresponding relationship between the parameter value range and the battery state can be determined by analyzing historical battery data. Each battery state can be determined according to one battery parameter or multiple battery parameters, which is not particularly limited in this embodiment of the present application.

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 according to the corresponding relationship between the parameter fitting result and the battery state. Using this method to determine the battery status is more accurate than using the parameter value range method. The parameter fitting result can be characterized by a function or a curve, which is not particularly limited in this embodiment of the present application.

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 can determine 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. For the specific training process, please refer to the relevant technical description, which will not be repeated here. The state determination model can accurately determine the battery state based on the input battery data.

The above methods of determining the battery state can also be used in combination, that is, the battery state is determined according to multiple methods. When the battery state determined by each method is the same, the battery state is determined as the final state of the replaced battery; if each method determines The battery states of different batteries are not exactly the same, and the battery state with the largest number of results can be selected as the final state of the replaced battery. Through the use of multiple methods for determining the battery state or their combined use, the battery state can be accurately judged, and the accuracy and effectiveness of battery management can be improved.

In the embodiment of this application, the advantages of the battery replacement mode are fully utilized, and the battery status is detected once every time the battery is replaced. Through high-frequency detection, corresponding measures are taken in time according to the battery status, which greatly improves the timeliness of battery management. sex.

Step 104 , perform a preset operation matching the state of the battery on the replaced battery.

In one embodiment, the correspondence between the battery state and the preset operation is preset, and in step 104, the preset operation matching the battery state of the replaced battery is determined and executed according to the correspondence.

The preset operations that match the status of the user's request for logout include: performing a logout operation and/or generating a logout reminder;

The preset operations matching the battery gradient utilization decommissioning status include: performing gradient utilization decommissioning operations and/or generating gradient utilization decommissioning reminders;

The preset operations matching the status to be maintained include: performing battery maintenance operations and/or generating elevator battery maintenance reminders;

The preset actions matching the abnormal state include: generating a battery abnormality reminder.

According to the different battery status, the replacement battery is targeted for treatment, realizing the safe and efficient use of the battery's entire life cycle, and giving full play to the value of each battery.

In one embodiment, after the preset operation matching the battery state is performed on the replaced battery, the battery data stored in the database is updated according to the execution result of the preset operation. When the preset operation of the battery is completed, each time When the battery is changed, the battery status is updated to ensure that the battery data matches the battery status as much as possible, so that the next battery change can accurately determine the battery status.

For example, the state to be maintained 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 battery has been replaced in the database is reset to recount the times of battery replacement.

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 that the history of the data can be traced back.

In the embodiment of the present application, the battery status of the replaced battery is determined according to the attribute data provided by the battery management platform and the battery replacement data provided by the replacement station, and based on the battery status, an operation matching the battery status is performed on the replaced battery, In this way, the automatic and efficient management of the battery life cycle is realized.

Fig. 2 is a flow chart of another battery management method provided by an exemplary embodiment of the present application. The management method is applied to a battery management platform, and the battery management platform can be deployed on a server of a battery swapping station, or can be deployed on another server. The battery management platform can also be realized by setting up another server; referring to Fig. 2, the management method includes the following steps:

Step 201, in response to a battery swap request of the vehicle, acquire vehicle data of the battery swap vehicle.

Step 203, according to the battery data, determine whether the replaced battery meets the maintenance conditions.

The battery data includes at least one of the following parameters: the number of battery changes and the time of the last battery change.

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 times the battery has been replaced is greater than the number threshold; Wherein, the number of times threshold and the duration threshold are set according to the actual situation, for example, the number of times threshold is set to 95, and the duration threshold is set to 6 months.

By combining the historical data of the battery, the number of battery changes and/or the time interval between battery changes is used as the basis for battery maintenance. The battery maintenance cycle is based on a certain number of battery changes, and the judgment of the battery change time interval is used as a supplementary basis. The above two These battery maintenance basis cooperate with each other to ensure the standardization and timeliness of battery maintenance.

Step 204, when it is determined that the replaced battery meets the maintenance conditions, generate a maintenance reminder for the replaced battery.

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

When the battery maintenance is completed, the battery status will be updated, and the cloud database will be used to store and manage the battery status information in a unified manner, which is convenient for battery fault recording, battery traceability, etc., and provides a data basis for battery management.

In one embodiment, when the replacement battery does not meet the maintenance conditions and the replacement battery is in a normal state, the battery data in the database is updated according to the replacement operation of the replacement battery by the replacement station, for example, the number of times of replacement is +1 .

In the above-mentioned embodiment, the vehicle data and battery data stored in the database are associated. The battery data can be stored in the database when the battery is newly connected to the network, or it can be the battery data that the battery replacement vehicle determines that the database does not exist when the battery is replaced. stored in the database.

In the embodiment of this application, according to the attribute data provided by the battery management platform and the battery replacement data provided by the battery replacement station, it is determined whether the replacement battery meets the maintenance conditions, and the battery that needs maintenance can be automatically found and maintained in time to ensure the health of the battery state.

Furthermore, by making full use of the advantages of the battery replacement mode, the battery status is checked every time the battery is replaced. Through high-frequency detection, comprehensive off-car maintenance is carried out on the battery in a timely manner according to the battery status, which greatly improves the maintenance efficiency of the battery. Timeliness; the characteristics of the battery replacement mode fundamentally overcome the greater risks caused by untimely battery maintenance and repairs caused by the negligence of electric vehicle users.

The following describes the implementation process of associatively storing vehicle data and battery data in the battery swapping scenario for the battery swapping vehicle.

Fig. 3 is a flow chart of a method for associatively storing vehicle data and battery data provided by an exemplary embodiment of the present application. The battery storage method includes the following steps:

Step 301. Obtain the first attribute data of the replaced battery identified by the battery compartment when the replaced battery is placed in the battery compartment.

The first attribute data includes at least one of the following parameters: battery number, rated capacity, rated voltage, source information, and the like.

In one embodiment, the first attribute data is obtained from the battery compartment by performing image recognition on the battery image of the replaced battery. The battery image is captured by the camera inside the battery compartment.

In one embodiment, the first attribute data is obtained through wireless signal transmission. Specifically, the electronic device acquires the first attribute data of the replaced battery, and transmits the first attribute data to the battery management platform through wireless signals.

Wherein, the electronic device may be, but not limited to, a mobile phone, a computer, a tablet computer, and the like.

Step 302, acquiring the entered second attribute data of the replaced battery.

In one embodiment, the second attribute data is entered through an electronic device.

Step 303, judging 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.

When the judgment result in step 303 is yes, execute step 304; when the judgment result in step 303 is no, execute step 305 to generate a data mismatch prompt to remind operation and maintenance personnel to perform data verification.

For example, if both the first attribute data and the second attribute data include battery code and source information, in step 303 it is judged whether the battery code included in the second attribute data matches the battery code included in the first attribute data, and the second 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. As long as there is a mismatch between battery code and source information, a data mismatch prompt will be generated.
