Next, a method for generating a battery passport according to an embodiment of the present application will be described in detail by taking an example in which the method according to an embodiment of the present application is applied to a battery passport generation system.

Referring to fig. 3, fig. 3 is a flowchart of a method for generating a battery passport according to an embodiment of the present application, as shown in fig. 3, the method includes the following steps:

Step 301: the battery passport generation system creates a preset data structure that includes a first field corresponding to static data of the battery and a second field corresponding to operational data of the battery.

In the embodiment of the application, a unified data structure, namely a preset data structure, is created in advance in face of the problems of diversity and non-uniformity of the battery passport standards. Based on the created preset data structure, the battery data can be integrated in advance according to the unified standard and stored in the preset data structure, so that the battery passport conforming to any battery passport standard can be generated according to the battery data of the unified standard conveniently, the situation that battery data conforming to different battery passport standard format requirements are required to be acquired for different battery passport standards respectively is avoided, and then the battery passport conforming to the corresponding battery passport standard is generated based on the data acquired respectively is avoided, so that the process of generating the battery passport is simplified, the efficiency of generating the battery passport is improved, and the battery data can be shared among different battery passport standards conveniently.

The first field comprises a plurality of fields which are respectively in one-to-one correspondence with the plurality of static data, and each field is used for storing the corresponding static data. The battery operation data also comprises a plurality of fields, and the second field comprises a plurality of fields which are respectively in one-to-one correspondence with the plurality of operation data, and each field is used for storing the corresponding operation data.

As one example, the preset data structure may be a data structure using classes, structures, dictionaries, arrays, hash tables, or the like.

Referring to fig. 4, fig. 4 is a schematic diagram of a logic structure of a preset data structure according to an embodiment of the application. As shown in fig. 4, the preset data structure 40 includes a first field 41 corresponding to static data and a second field 42 corresponding to operation data. The first field 41 includes, among other things, field 0, field 1, field 2, field m, which correspond to different static data, respectively. The second field 42 includes a field 0, a field 1, a field 2, a field n, which respectively correspond to different operation data.

As an example, assuming that the static data includes manufacturer name, date of production, place of production, battery type and rated capacity of the battery, and the operation data includes each charge duration, each discharge duration, voltage and power during operation, one possible preset data structure described by the code may be as follows:

class BatteryData{

public:

string manufacturer; name of the manufacturer

String productionDate; date of production

String productionLocation; production site

String batteryType; type of/(Battery)

Double ratedCapacity; rate/rated capacity, unit: mAh

Vector < double > CHARGINGTIMESECS; time duration per charge, unit: second of

Vector < double > DISCHARGINGTIMESECS; time duration per discharge, unit: second of

Vector < double > voltageMv; voltage/unit: mV (mV)

Vector < double > CAPACITYMWH; charge/unit: mWh

}。

It should be noted that, step 301 may be performed in a case where the preset data structure is not yet created, and if the preset data structure is created, step 301 is not required to be performed.

Step 302: the battery passport generation system obtains first battery data for the target battery, the first battery data including first static data and first operational data.

The first static data is static data of the target battery, and the first operation data is operation data of the target battery. Static data and operation data have been described in detail in the above description of nouns, and embodiments of the present application are not described in detail herein.

As one example, raw battery data of a target battery may be first acquired, the raw battery data including raw static data and raw operational data. And then, carrying out format conversion on the original battery data according to the format requirement of the preset data structure to obtain first battery data which meets the format requirement of the preset data structure.

Thus, the data format of the battery data can be unified, and the format standardization of the battery data can be realized.

The method for converting the format of the original battery data according to the format requirement of the preset data structure comprises the following steps: performing format conversion on the original static data according to the format requirement of the preset data structure to obtain first static data which meets the format requirement of the preset data structure; and converting the format of the original operation data according to the format requirement of the preset data structure to obtain first operation data which accords with the format requirement of the preset data structure.

Step 303: the battery passport generation system stores the first battery data in a preset data structure.

In the embodiment of the application, different battery data in the first battery data can be respectively stored in the corresponding fields of the preset data structure. For example, the first static data is correspondingly stored in a first field of the preset data structure, and the first running data is correspondingly stored in a second field of the preset data structure.

As an example, assuming that the manufacturer name is "ABCDEFG", the production date is "2022-06-15", the production site is "region a", the battery type is "lithium ion battery", and the rated capacity is "4000", one possible implementation of storing the first static data in the first field of the preset data structure correspondingly by the code description may be as follows:

BatteryData x batteryData = new BatteryData (); data of new battery

batteryData->manufacturer＝"ABCDEFG Inc."；

batteryData->productionDate＝"2022-06-15"；

batteryData->productionLocation＝"A"；

BatteryData- > batteryType = "lithium-polymer"; lithium ion battery

batteryData->ratedCapacity＝4000。

As an example, assume that the battery is charged twice during operation, and the charging durations are respectively: 3000 seconds, 1800 seconds; 3 times of discharge are carried out, and the discharge time periods are respectively as follows: 6000 seconds, 7200 seconds, 2000 seconds; the voltages at different time periods according to the time sequence are respectively as follows: 3750mV, 3650mV, 3600mV and 3500mV; the electric quantity in different time periods according to the time sequence is respectively as follows: 15mWh, 20mWh, 25mWh and 22mWh; one possible implementation of storing the first running data in the second field of the preset data structure by code description may be as follows:

vector < double > CHARGINGTIMESECS {3000,1800}; charge time, units: second of

Vector < double > DISCHARGINGTIMESECS {6000,7200,2000}; time of discharge, unit: second of

Vector < double > voltageMv {3750,3650,3600,3500}; voltage/unit: mV (mV)

Vector < double > batteryCapacityMwh {15,20,25,22}; charge/unit: mWh;

batteryData->chargingTimeSecs＝chargingTimeSecs；

batteryData->dischargingTimeSecs＝dischargingTimeSecs；

batteryData->voltageMv＝voltageMv；

batteryData->capacityMwh＝batteryCapacityMwh。

In addition, as the operational data of the battery changes, some static data of the battery may also change. For example, as the operating data of the battery changes, the battery state in the static data of the battery may change. Based on this, the step of correspondingly storing the first static data in the first field of the preset data structure may be replaced by: and adjusting the first static data according to the first operation data to obtain second static data, and correspondingly storing the second static data in a first field of a preset data structure. Therefore, the battery data can be perfected, and the accuracy of the battery data is improved.

Accordingly, the second static data and the first operation data stored in the preset data structure may be processed in the following steps to generate a battery passport of the target battery.

Step 304: the battery passport generation system obtains the first battery data from the preset data structure.

Step 305: the battery passport generation system performs data processing on the first battery data according to the format requirements of the specified battery passport standard to obtain second battery data which meets the format requirements of the specified battery passport standard.

Wherein the specified battery passport standard is any of a variety of battery passport standards.

In the embodiment of the application, the first battery data can be processed according to the format requirement of any battery passport standard to generate the battery passport conforming to any battery passport standard, that is, the battery passport conforming to any battery passport standard can be generated based on the first battery data.

The standard format requirements of the battery passport may generally specify the order of arrangement of the data, the manner of separation between the data, the data format of the second battery data to be output, and the like. Accordingly, the data processing of the first battery data according to the format requirement of the specified battery passport standard to obtain the second battery data meeting the format requirement of the specified battery passport standard may include the steps of:

1) And arranging a plurality of data in the first battery data according to a preset data arrangement sequence by adopting a preset separation symbol to obtain third battery data.

The data in the third battery data are separated by a preset separation symbol, the preset data arrangement sequence is the data arrangement sequence specified in the format requirement of the specified battery passport standard, and the preset separation symbol is the separation symbol specified in the format requirement of the specified battery passport standard.

Wherein the preset separation symbol comprises a separator and/or a linefeed. For example, the separator is a predetermined character or a predetermined character string, such as "\n".

std::cout<<completePassport<<std::endl。

step 307: and performing data type checking and data checking on the electronic document.

The electronic document comprises a plurality of data corresponding to the first battery data, and the data type checking and the data checking are carried out on the electronic document, namely the data type checking and the data checking are carried out on the plurality of data.

1, Checking the data type.

The data type checking means that all or part of the data in the plurality of data are subjected to data type checking to detect whether the data meet the corresponding data type requirement, if yes, the data type checking is determined to be passed, and if not, the data type checking is determined to be failed.

Wherein the data type check may include one or more of the following checks: type matching, data length checking, data scope checking, data format checking, field value checking, constraint relation checking, and logical checking.

For example, the plurality of data includes first data, and the electronic document is subjected to data type checking, including one or more of the following modes:

1) Type matching.

Detecting whether the data type of the first data is a preset data type corresponding to the first data, if so, determining that the passing type is matched, and if not, determining that the passing type is not matched.

2) And checking the data length.

3) And (5) checking the data range.

4) And checking the data format.

5) And checking a field value.

6) And (6) checking constraint relation.

7) And (5) logic checking.

And 2, checking data.

As one example, a preset verification algorithm may be employed to perform data verification on the electronic document. The preset checking algorithm can be a number school checking algorithm, a checksum algorithm, a CRC (Cyclic Redundancy Check ) algorithm, a hash checking algorithm and the like, and the checking algorithm is not limited in the embodiment of the application.

For example, performing data verification on the electronic document includes: acquiring a verification value corresponding to the electronic document; calculating the electronic document by adopting a preset algorithm to obtain a calculated value; comparing the verification value with the calculated value; and if the verification value is the same as the calculated value, determining that the electronic document passes the data verification.

The preset algorithm corresponds to the adopted verification algorithm. For example, the preset algorithm may be a mathematical algorithm corresponding to a mathematical school checking algorithm, a checksum calculating method corresponding to a checksum algorithm, a CRC algorithm corresponding to a CRC checking algorithm, a hash algorithm corresponding to a hash checking algorithm, or the like, which is not limited in the embodiment of the present application.

As an example, the calculating the electronic document using a preset algorithm includes: and calculating a data sequence consisting of a plurality of data by adopting a preset algorithm to obtain a calculated value.

It should be noted that, the verification value is usually calculated by a preset algorithm on the electronic document in advance to obtain data. If any data in the electronic document is tampered, the corresponding check value and the calculated value are different, so that the data error or the data tampering of the electronic document can be found.

The data type of the electronic document can be ensured to meet the format requirement by checking the data type of the electronic document, and the data of the electronic document can be ensured to be correct by checking the data of the electronic document, so that the consistency and the integrity of the generated data of the electronic document can be ensured.

Step 308: if the electronic document passes the data type check and the data verification, a first cell passport of the target cell is generated from the electronic document, the first cell passport including document content of the electronic document and a corresponding cell passport identification.

Wherein the electronic document includes second battery data. The battery passport identification corresponding to the electronic document is used for uniquely identifying the corresponding electronic document. The battery passport identification may be generated according to a predetermined algorithm, and the battery passport identification may be a battery passport ID (Identity Document, identification number), or the like.

As one example, passport data may be determined from an electronic document, and then a first battery passport may be generated from the electronic document and the passport data. The passport data includes a battery passport identification, and may also include other data such as value chain data.

As one example, a first battery passport of a preset form may be generated from an electronic document. The preset form may include a file form, a picture form, a graphic code form, a link form, or the like.

The file form may be a file form of a specified file format. For example, the specified file format may be a PDF file format or a JSON (JavaScript Object Notation, JS object profile) file format, or the like. The graphic code may be in the form of a bar code or a two-dimensional code, etc. The two-dimensional code may be a QR (Quick Response) code or the like.

For example, outputting the electronic document as a first battery passport in a preset form may include any one of the following:

the first implementation mode: a first file of a specified file format is generated from the electronic document, the first file including document content of the electronic document and a corresponding battery passport identification.

Wherein the first document is a first battery passport in the form of a document. The specified file format may be PDF file format or JSON file format, etc., which is not limited by the embodiment of the present application.

The second implementation mode: a first file of a specified file format is generated from the electronic document, and a link to the first file is generated from the first file.

Wherein the link of the first document is a first battery passport in the form of a link. The linking of the first file is used to open the first file.

That is, after the first file is generated, the first file may be exported in a linked form for viewing and sharing by the user.

Third implementation: a graphic code is generated from the electronic document, the graphic code including document content of the electronic document and a corresponding battery passport identification.

Wherein the graphic code is a first battery passport in the form of a graphic code. For example, the graphic code may be a two-dimensional code in the form of a QR code or the like.

As one example, in the case where the graphic code is a QR code, generating the graphic code from the electronic document may include the steps of:

1. And encoding the specified data in the electronic document by adopting a preset encoding mode so as to convert the specified document data in the electronic document into binary data.

Wherein the specified document data may be all or part of the data in the electronic document. For example, the specified document data may be data to be presented specified by a specified battery passport standard.

2. The binary data is converted into a QR code.

As one example, converting binary data into a QR code may include the steps of:

1) And partitioning the binary data to obtain a plurality of data blocks.

Each of the plurality of data blocks may contain a fixed amount of binary data, or the data amount of each of the plurality of data blocks may be set according to the capacity and requirements of the QR code, so as to ensure that the QR code can contain sufficient information.

2) A check code and an error correction code are added to the plurality of data blocks.

Wherein the check code may be used to detect and correct errors in the input data. The error correction code has certain error correction capability, can be used for correcting a certain number of data errors, and improves the fault tolerance of input data. Therefore, by adding the check code and the error correction code into a plurality of data blocks, the accuracy of data and the fault tolerance of the subsequently generated QR code can be improved.

As one example, adding a check code to a plurality of data blocks includes: and generating a check code corresponding to each data block according to each data block in the plurality of data blocks, and adding the corresponding check code into each data block.

The check code corresponding to each data block may be redundant data obtained by calculating the data block by using a check algorithm. For example, the checking algorithm may be a CRC algorithm or the like. The check code may be added at the end of the corresponding data block, etc., or otherwise embedded in the data block.

As one example, error correction codes are added in a plurality of data blocks after the error correction codes are added. The length and the error correction capability of the error correction code can be determined according to the capacity and the fault tolerance level of the QR code.

3) And converting the plurality of data blocks added with the check code and the error correction code into a QR code.

For example, a first preset function may be called, and the plurality of data blocks to which the check code and the error correction code are added are converted into QR codes through the first preset function. The first preset function is used for converting data into a QR code.

For example, a plurality of data blocks to which the check code and the error correction code are added may be combined in accordance with the arrangement order required by the QR code, and then the combined data blocks may be converted into the QR code.

Fourth implementation: generating a graphic code according to the electronic document, and generating a link of the graphic code or a picture comprising the graphic code according to the graphic code.

That is, after the graphic code is generated, the graphic code may be exported in a pictorial form or a linked form for viewing and sharing by the user.

As an example, taking a graphic code as a QR code as an example, after the QR code is generated from the electronic document, the QR code may be encoded in a black-and-white channel to generate a picture including the QR code.

In addition, if the electronic document fails the data type check or fails the data verification, it indicates that the data type of the electronic document is not satisfactory, or the data may be tampered, in which case, the step is ended, that is, the first battery passport is not generated according to the electronic document.
