As large-scale retirement of traction batteries occurs, the proper and regulated recycling of these batteries has become a major concern. Improper handling of the tens of thousands of tons of retired traction batteries generated each year can result in immeasurable pollution to the environment. Currently, in China, the primary recycling modes for handling retired traction batteries are regeneration utilization and cascade utilization. In the prior art, when determining the recycling mode for retired traction batteries, the main considerations are the remaining capacity, internal resistance, and external damages of the batteries, completely overlooking the consideration of carbon emissions. As a result, the final decision on the recycling mode for retired batteries may result in significant carbon emissions and environmental pollution. In view of this, examples of the present disclosure provide a determination method and apparatus of recycling mode for battery, an electronic device, and a storage medium. By comparing the carbon emissions per single charge-discharge of regeneration-utilized and cascade-utilized batteries to choose the recycling mode with less carbon emissions for battery recycling, retired batteries can be processed into low-carbon battery products to meet the demand of energy storage companies and new energy vehicle manufacturers for low-carbon products, which ultimately realizes low carbon and environmental protection. The examples of the present disclosure will be described in detail below with reference to the accompanying drawings. The determination method and apparatus of recycling mode for battery according to the examples of the present disclosure can be implemented by an electronic device. In the present solution, the main consideration is low carbon and environmental protection when determining the battery recycling mode. By comparing the carbon emissions per single charge-discharge of regeneration-utilized and cascade-utilized batteries, the recycling mode with less carbon emissions is chosen for battery recycling. Since carbon emissions are affected by factors such as cycle number of battery, battery charge-discharge efficiency, battery capacity retention rate, power emission factor, rated capacity of battery, and carbon emissions from recycling process, it is necessary to pre-configure parameters, such as cycle number of battery, battery charge-discharge efficiency, battery capacity retention rate, power emission factor, rated capacity of battery, carbon emissions from recycling process, of common batteries in the electronic device in advance The determination method and apparatus of recycling mode for battery according to the examples of the present disclosure are implemented by an electronic device, and the electronic device executes the determination method of recycling mode for battery according to the examples of the present disclosure. In the examples of the present disclosure, the electronic device may be, but is not limited to, a personal computer (PC), a notebook computer, a server or other electronic devices having data calculation, analysis and processing capabilities. Hereinafter, the determination method of recycling mode for battery according to the examples of the present disclosure will be described based on the fact that preset battery parameters corresponding to battery types of common batteries have been pre-configured in the electronic device. Referring to , shows a schematic flowchart of a determination method of recycling mode for battery according to an example of the present disclosure. The method includes the following steps. Step S101, a battery type of a subject battery is acquired to determine preset battery parameters corresponding to the battery type, wherein the preset battery parameters include cycle number of battery, battery charge-discharge efficiency, battery capacity retention rate, power emission factor, rated capacity of battery, and carbon emissions from recycling process. In an example of the present disclosure, preset parameters of common battery types are pre-stored in the electronic device. The preset parameters include, but are not limited to, cycle number of battery, battery charge-discharge efficiency, battery capacity retention rate, power emission factor, rated capacity of battery, and carbon emissions from are cycling process. When a battery recycling mode is to be determined for a specific battery, the battery type of the subject battery is firstly obtained, and then the matching preset battery parameters are retrieved based on the battery type. Step S102, the carbon emissions from power loss are obtained according to the battery type, cycle number of battery, battery charge-discharge efficiency, battery capacity retention rate, power emission factor, and rated capacity of battery, wherein the carbon emissions from power loss are carbon emissions generated by power loss during charging and discharging of battery. In an example of the present disclosure, firstly, the electronic device obtains an actual battery capacity according to the rated capacity of battery and the battery capacity retention rate, wherein the actual battery capacity refers to the electrical energy consumed when the current battery is charged. Then, the lost electrical energy during the charge-discharge process of the battery is obtained according to the actual capacity of the battery and the battery charge-discharge efficiency. Finally, the carbon emissions from power loss are obtained according to the lost electrical energy during the charge-discharge process of the battery and the power emission factor. It should be noted that the battery capacity retention rate is used to indicate the ratio of the current battery capacity to the rated capacity of battery; the battery charge-discharge efficiency is used to indicate a ratio of the discharged electrical energy of the battery to a consumed electrical energy of the battery when charging; the rated capacity of battery is used to indicate a factory-fresh capacity of the battery and can be obtained by various means, including but not limited to scanning a QR code of the battery; and the cycle number of battery is used to indicate charge-discharge times of a battery. In practical applications, the carbon emissions from power loss may also be calculated using the following formula: where denotes carbon emissions generated by power loss due to battery charge-discharge efficiency during battery operation, denotes an electrical energy consumed by battery charging, denotes an electrical energy discharged by the battery, and EF denotes an power emission factor, which can be assumed as the grid emission factor of domestic power grid, i.e. . Step S103, carbon emissions per single charge-discharge of regeneration-utilized and cascade-utilized batteries are obtained respectively, according to the carbon emissions from power loss, the carbon emissions from recycling process and the battery cycle life. In the examples of the present disclosure, a battery after a regeneration utilization treatment becomes a new battery that is ready to be delivered from the factory, in which case the battery cycle life represents the remaining battery charge-discharge times that the battery can undergo from the time of delivery until the retirement of the battery, while the battery cycle life of a battery after a cascade utilization treatment refers to the remaining battery charge-discharge times that the battery can undergo from the time of retirement until the battery no longer holds any value for cascade utilization. Herein, the carbon emissions generated in the battery life cycle can be obtained according to the carbon emissions from power loss and carbon emissions from recycling process, and then combined with the battery cycle life, the carbon emissions per single charge-discharge of regeneration-utilized and cascade-utilized batteries can be obtained. Step S104, the carbon emissions per single charge-discharge of regeneration-utilized and cascade-utilized batteries are compared to determine the recycling mode with less carbon emissions as a target recycling mode for the subject battery. It can be seen that, according to the determination method of recycling mode for battery provided by the example, acquiring a battery type of a subject battery in the electronic device, so as to determine preset battery parameters corresponding to the battery type, wherein the preset battery parameters include cycle number of battery, battery cycle life, battery charge-discharge efficiency, battery capacity retention rate, power emission factor, rated capacity of battery, and carbon emissions from recycling process; obtaining the carbon emissions from power loss according to the battery type, cycle number of battery, battery charge-discharge efficiency, battery capacity retention rate, power emission factor, and rated capacity of battery, wherein the carbon emissions from power loss are carbon emissions generated by power loss during charging and discharging of battery; obtaining carbon emissions per single charge-discharge of regeneration-utilized and cascade-utilized batteries respectively, according to the carbon emissions from power loss, the carbon emissions from recycling process and the battery cycle life; and comparing the carbon emissions per single charge-discharge of regeneration-utilized and cascade-utilized batteries, to determine the recycling mode with less carbon emissions as the target recycling mode for the subject battery, retired batteries can be processed into low-carbon battery products to meet the demand of energy storage companies and new energy vehicle manufacturers for low-carbon products, which ultimately realizes low carbon and environmental protection. Optionally, for the preset battery parameters corresponding to the battery types mentioned in the above example, users can preset the parameters through an interactive user interface or a third-party server as an execution device of the present solution. In a possible example, on the basis of and with reference to , before step S101, the method further includes: presetting the cycle number of battery, rated capacity of battery, battery type, carbon emissions from recycling process, power emission factor, battery capacity retention rate and battery charge-discharge efficiency corresponding to each battery type, respectively; wherein the battery capacity retention rate and the battery charge-discharge efficiency are determined by fitting sampled data of a plurality of the battery types. Specifically, the sampled data may be: battery cycle life, cycle number of battery, battery charge-discharge efficiency, etc. In the battery recycling process, first, the recovered battery packs are deeply discharge to lower the voltage below the safe disassembly voltage. This deep discharge is necessary to prevent the battery packs from being disassembled with electricity, which may cause personal injury and spontaneous combustion caused by battery damage during disassembly. Once the battery packs have been discharged, they are disassembled by disassembling equipment to obtain battery modules. Additionally, if needed, the battery modules can be further disassembled into battery cells. A charge-discharge tester is used to measure the battery charge-discharge efficiency, battery internal resistance, cycle number of battery, and other performance indicators. The batteries are then sampled and selected to assess their cycle number, battery charge-discharge efficiency, and other information under conditions where the capacity retention rate drops below 10% from retirement, so as to form a sampled data for cycle number of battery. Subsequently, the formed sampled data of battery life cycle is calculated and fitted to determine battery capacity retention rate and battery charge-discharge efficiency. Optionally, in practical applications, the power loss in charging and discharging of battery is affected by battery charge-discharge efficiency, which in turn is related to the cycle number of battery. The battery charge-discharge efficiency and the cycle number of battery satisfy the following relationship: where denotes the battery charge-discharge efficiency and denotes the cycle number of battery. For the battery charge-discharge efficiency and cycle number of battery involved in the present solution, empirical values corresponding to each battery type can be obtained by statistically summarizing the charging and discharging data of batteries of different battery types before implementing the present solution. In an example of the present disclosure, the battery charge-discharge efficiency is determined by fitting the sampled data of cycle number of battery. As shown in , as the number of battery uses increases, the battery charge-discharge efficiency decreases and the discharging capacity of the battery declines. Optionally, in practical applications, the actual capacity of the battery is affected by the battery capacity retention rate, which in turn is related to the cycle number of battery. Hereinafter, three battery types are taken as examples for detailed explanation. The battery capacity retention rate and the cycle number of battery of a first battery type, a second battery type, and a third battery type satisfy the following relationships: where denotes the cycle number of battery, denotes a battery capacity retention rate of the first battery type, denotes a battery capacity retention rate of the second battery type, and denotes a battery capacity retention rate of the third battery type. For the battery capacity retention rate and cycle number of battery involved in the present solution, empirical values corresponding to each battery type can be obtained by statistically summarizing the data of actual battery capacity and rated capacity of battery of different battery types before implementing the present solution. Specifically, the relationship between battery capacity retention rate and cycle number of battery for the first battery type is as shown in , the relationship between battery capacity retention rate and cycle number of battery for the second battery type is as shown in , and the relationship between battery capacity retention rate and cycle number of battery for the third battery type is as shown in . It should be noted that in the examples of the present disclosure, the first battery type, second battery type, and third battery type mentioned are examples of battery types provided for illustration purposes. The battery types can be classified based on testing of batteries from different manufacturers. The examples of the present disclosure do not impose any specific limitations on the classification method for battery types. Different classification methods may yield varying relationships between battery capacity retention rate and cycle number of battery. Optionally, in practical applications, in order to choose the mode with minimal carbon emissions for recycling, it is necessary to obtain the carbon emissions of two important stages in the battery life cycle, one of which is the carbon emissions from power loss during charging and discharging of battery. The formulae for calculating the carbon emissions from power loss for the first battery type and the second battery type are as follows: where denotes carbon emissions from power loss for the regeneration utilization of the first battery type, denotes carbon emissions from power loss for the cascade utilization of the first battery type, denotes carbon emissions from power loss for the regeneration utilization of the second battery type, denotes carbon emissions from power loss for the cascade utilization of the second battery type, denotes a rated capacity of battery of the first battery type, denotes a rated capacity of battery of the second battery type, EF denotes a power emission factor, denotes a battery charge-discharge efficiency, denotes a battery capacity retention rate of the first battery type, and denotes a battery capacity retention rate of the second battery type. Optionally, in practical applications, the carbon emissions from recycling process can be obtained directly, or it can be obtained by the carbon emissions from every stage of the recycling process using the following formula: where E denotes carbon emissions from recycling process, denotes a mass or energy of raw and auxiliary materials and energy source used in stages of the recycling process, and denotes an emission factor for the mass or energy of raw and auxiliary materials and energy source used in stages of the recycling process. For the battery recycling process, when the battery is recycled in different modes, the treatment stages involved in the recycling process are different. The battery recycling modes in the application scenario are regeneration utilization and cascade utilization. Herein, cascade utilization is considered as mild scraping, where the battery itself is not fully retired but is no longer suitable for use in new energy vehicles, and can be used in other fields after treatment. The battery recycling process for cascade utilization includes but is not limited to transportation, dismantling, performance testing, battery management system (BMS) evaluation, assembly, and packaging and transportation. Compared with the cascade utilization, regeneration utilization is considered as severe scraping, where it is necessary to extract the scarce resources from the battery through chemical processes to achieve battery re-manufacturing. The battery recycling process for regeneration utilization includes but is not limited to packaging, transportation, physical discharge, chemical discharge, dismantling, crushing, pyrolysis, sorting, acid leaching, extraction, precipitation, mixing, calcination, impurity removal, and packaging. In order to explain more clearly the determination method of recycling mode for battery provided by the examples of the present disclosure, the first battery type and the second battery type will be used as examples for illustrative description below. In this example, assuming that the subject battery for which a recycling mode is to be determined is the first battery type, the rated capacity of battery is 75 kWh, the carbon emissions from recycling process when the battery is subject to regeneration utilization are 47.01 kgCO2e/kWh, the carbon emissions from recycling process when the battery is subject to cascade utilization are 16.21 kgCO2e/kWh, the battery cycle life for regeneration utilization is 2010, the battery cycle life for cascade utilization is 160, the battery capacity retention rate is about 48%, and as can be seen from , the cycle number of battery is about 2370. Hence, After calculation, the carbon emissions for regeneration utilization of the battery are 1.47 kgCO2e per cycle, while the carbon emissions for cascade utilization of the battery are 2.94 kgCO2e per cycle. Therefore, the carbon emissions per single charge-discharge for cascade-utilization is higher than that for regeneration-utilization, so it is suggested that the battery should be recycled in the regeneration utilization mode. In this example, assuming that the subject battery for which a recycling mode is to be determined is the second battery type, the rated capacity of battery is 50 kWh, the carbon emissions from recycling process when the battery is subject to regeneration utilization are 49.21 kgCO2e/kWh, the carbon emissions from recycling process when the battery is subject to cascade utilization are 16.86 kgCO2e/kWh, the battery cycle life for regeneration utilization is 2100, the battery cycle life for cascade utilization is 490, the battery capacity retention rate is about 61%, and as can be seen from , the cycle number of battery is about 2790. Hence, After calculation, the carbon emissions for regeneration utilization of the battery are 1.48 kgCO2e per cycle, while the carbon emissions for cascade utilization of the battery are 2.94 kgCO2e per cycle. Therefore, the carbon emissions per single charge-discharge for cascade utilization is higher than that for regeneration utilization, so it is suggested that the battery should be recycled in the regeneration utilization mode.
