[0060] S4. Repeat steps S1 to S3 until the battery is fully charged.

[0061] As can be seen from the above description, the beneficial effects of the present invention are as follows: It provides an adaptive battery full-charge calibration method, which collects the battery's state parameters in real time during the battery charging process, combines an adaptive algorithm to calculate the expected full-charge time and expected full-charge amount under the current charging strategy, and determines the difference based on the comparison between the expected full-charge time and expected full-charge amount and the actual demand, so as to adjust the current charging strategy in reverse.

[0084] S3. Compare the estimated full charging time and the estimated full charging amount with the actual demand, determine the difference, and adjust the current charging strategy.

[0085] S4. Repeat steps S1 to S3 until the battery is fully charged.

[0086] As described above, the beneficial effects of this invention are as follows: Based on the same technical concept, and in conjunction with the aforementioned adaptive battery full-charge calibration method, an adaptive battery full-charge calibration terminal is provided. This terminal collects battery state parameters in real time during battery charging, combines an adaptive algorithm to calculate the expected full-charge time and expected full-charge amount under the current charging strategy, and determines the difference by comparing the expected full-charge time and expected full-charge amount with the actual demand, thereby adjusting the current charging strategy accordingly.

[0093] Otherwise, adjustments should be made based on the priority of user needs.

[0094] As described above, the charging strategy is dynamically adjusted based on the difference between the expected full charge time and expected full charge amount calculated in real time by the adaptive algorithm and the actual demand. This can adapt to changes in different battery types and states, improve charging efficiency and full charge accuracy, and is applicable to different types of batteries and different charging environments, thus having wide applicability.

[0095] The present invention provides an adaptive battery full charge calibration method and terminal, which is mainly applied to the battery charging scenario of electric vehicles. The following is a detailed description with reference to specific embodiments.

[0096] Please refer to Figure 1 Embodiment 1 of the present invention is as follows:

[0097] An adaptive battery full charge calibration method, such as Figure 1 As shown, the steps include:

[0098] S0. Obtain the initial battery parameters, which include the battery capacity Q_total, the battery internal resistance R_int, and the battery initial voltage V_init. By combining the initial battery parameters, the expected full charge time and expected full charge amount can be accurately calculated under the adaptive algorithm.

[0099] S1. During the charging process, the charging status of the battery is detected in real time to obtain real-time battery parameters, including the current battery voltage V_current, the current battery current I_current, the current temperature T, and the SOC of each individual cabinet.

[0100] S2. Based on the initial battery parameters and real-time battery parameters, combined with an adaptive algorithm, the estimated full charge time and estimated full charge amount under the current charging strategy are calculated as follows:

[0101] S21. The formula for calculating the expected full charge time T_full is defined as follows:

[0102] T_full=f(Q_remaining,I_current,R_int,T) (1);

[0103] Where Q_remaining represents the current remaining capacity of the battery, and f is a function relationship determined based on battery characteristics and charging environment factors.

[0104] The formula for calculating the functional relationship f is as follows:

[0105]

[0106] α, β, and γ are constants determined through experiments and data analysis, used to reflect the influence of battery characteristics and charging environment factors on charging time.

[0107] S22. The formula for calculating the expected full charge capacity Q_full is defined as follows:

[0108] Q_full=Q_total-Q_loss (3);

[0109] Wherein, Q_loss is the power loss calculated based on the battery internal resistance R_int, the battery current I_current, and the charging time.

[0110] The formula for calculating the power loss Q_loss is as follows:

[0111]

[0112] Where k is the influence coefficient of the battery internal resistance R_int on the power loss Q_loss, and η is the energy conversion efficiency during charging. In this embodiment, the values ​​of k and η need to be determined through experiments and data analysis.

[0113] S3. Compare the expected full charge time and expected full charge amount with the actual demand, identify the difference, and adjust the current charging strategy.

[0114] S4. Repeat steps S1 to S3 until the battery is fully charged.

[0115] In this embodiment, by collecting battery state parameters in real time during battery charging, and combining this with an adaptive algorithm to calculate the estimated full charge time and estimated full charge amount under the current charging strategy, the difference between the estimated full charge time and estimated full charge amount and the actual demand is determined to adjust the current charging strategy accordingly. This achieves dynamic adjustment of the charging strategy during the charging process to adapt to changes in different battery types and battery states, reducing ineffective charging time, improving charging efficiency, and achieving full charge calibration to avoid safety issues such as battery overcharging and overheating. The specific implementation of the adaptive algorithm's calculation formula can be based on a comprehensive consideration of the battery's chemical characteristics, physical characteristics, and charging environment. The battery's chemical characteristics include the state of charge (SOC) of each individual battery cell, and its physical characteristics include the battery's internal resistance. The charging environment includes parameters such as charging current, charging voltage, and temperature. By monitoring and calculating these parameters in real time, a more accurate estimated full charge time and estimated full charge amount can be obtained, thereby achieving precise battery full charge calibration.

[0116] Embodiment 2 of the present invention is as follows:

[0117] An adaptive battery full charge calibration method, based on the above embodiment one, specifically includes step S3 as follows:

[0118] S31. Compare the estimated full charge time with the user's required time. If the estimated full charge time is less than or equal to the user's required time, it means that the current charging strategy can meet the user's needs and no adjustment is needed. Otherwise, it means that the current charging strategy is inefficient and needs to be adjusted to shorten the charging time. This can be achieved by increasing the battery current I_current or the battery current charging voltage V_set in the current charging strategy.

[0119] S32. Compare the expected full charge capacity with the user's required capacity. If the expected full charge capacity is greater than or equal to the user's required capacity, it means that the current charging strategy can meet the user's needs and no adjustment is required. Otherwise, it means that the battery may not be able to reach the user's expected capacity and the charging strategy needs to be adjusted to increase the full charge capacity. This can be achieved by extending the charging time of the current charging strategy or reducing the power loss Q_loss during the charging process (such as by reducing the charging current to reduce internal resistance heating).

[0120] S33. Taking into account both the expected full charge time and the expected full charge amount, if the expected full charge time and the expected full charge amount meet the user's needs, then the current charging strategy can meet the user's needs and no adjustment is required; if there is a conflict between the expected full charge time and the expected full charge amount (e.g., increasing the charging current can shorten the charging time but may increase the power loss), then it is necessary to weigh and adjust according to the priority of the user's needs.

[0121] This means that the charging strategy is dynamically adjusted based on the difference between the expected full charge time and expected full charge amount calculated in real time by the adaptive algorithm and the actual demand. It can adapt to changes in different battery types and states, improve charging efficiency and achieve full charge calibration. It is suitable for different types of batteries and different charging environments, and has wide applicability.

[0122] Please refer to Figure 2 Embodiment 3 of the present invention is as follows:

[0123] An adaptive battery full charge calibration terminal 1 includes a memory 2, a processor 3, and a computer program stored on the memory 2 and executable on the processor 3. When the processor 3 executes the computer program, it completes the steps in the adaptive battery full charge calibration method described in Embodiment 1 or Embodiment 2 above.

[0124] In summary, the adaptive battery full-charge calibration method and terminal provided by this invention have the following advantages:

[0125] Beneficial effects:

[0126] 1. Improve charging efficiency: By monitoring the battery's charging status in real time and adjusting the charging strategy, ineffective charging time is reduced, thereby improving charging efficiency.
