[0029] This embodiment provides a method for controlling the power of an electronic device operating in the aforementioned vehicle. Figure 1 This is a flowchart of a power control method according to an embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:
[0030] Step S10: Obtain the target dataset, which includes: first data, second data, and third data. The first data represents the performance parameters of the power battery at the current moment. The second data is obtained by analyzing the historical behavior of the target user. The third data is determined by the information transmitted by the power supplier.
[0031] The first set of data mentioned above may include voltage, current, temperature, battery state of charge (SOC), battery state of health (SOH), and battery charging / discharging power. The second set of data may include the user's target charge / discharge capacity and desired charging / discharging time for the electric vehicle.

[0032] Step S12: Determine the charging and discharging power information based on the target dataset. The charging and discharging power information is used to record the charging and discharging power of the power battery installed in the target vehicle at multiple different temperatures and multiple different states of charge.
[0033] Step S14: Control the power supply circuit set in the target vehicle to supply power according to the charging and discharging power information, so that the power battery and the power supply can exchange electricity.
[0034] In this embodiment of the invention, a target dataset is first acquired, and then charge / discharge power information is determined based on the target dataset. The charge / discharge power information is used to record the charge / discharge power of the power battery installed in the target vehicle at multiple different temperatures and multiple different states of charge. Finally, the power supply circuit installed in the target vehicle is controlled to supply power according to the charge / discharge power information, so that the power battery and the power supplier can interact in terms of electricity. This achieves the purpose of controlling the power supply circuit to supply power according to the charge / discharge power information, so that the power battery and the power supplier can interact in terms of electricity. This achieves the technical effects of extending battery life, improving power utilization efficiency, enhancing user experience, and reducing carbon emissions, thereby solving the technical problems of short battery life, low power utilization efficiency, and poor user experience in power control methods.
[0035] Optionally, in step S10, obtaining the first data may include the following execution steps:
[0036] Step S101: Collect sensor data from the power battery to obtain the collection results, wherein the collection results are used to represent the usage attributes of the power battery;
[0037] Step S102: Preprocess the collected results to obtain the preprocessed results;
[0038] Step S103: Obtain the first data based on the acquisition results and preprocessing results.
[0039] The above data collection results include the voltage and temperature of the power battery. The preprocessing results can include battery SOC, battery SOH, current battery charge / discharge power prediction, and renewable energy power prediction for the next period. Furthermore, battery SOC can be understood as the ratio of the battery's remaining capacity after a period of use or long-term disuse to its capacity in a fully charged state. Its value ranges from 0 to 1; when SOC = 0, the battery is fully discharged, and when SOC = 1, the battery is fully charged. Battery SOH is defined as the ratio of the capacity released by a power battery from a fully charged state to the cutoff voltage under standard conditions to its corresponding nominal capacity. The charge / discharge rate can be the current value required for the battery to release its rated capacity within a specified time.
[0040] Based on the above steps S101 to S103, firstly, by collecting sensor data in the power battery, the current voltage and temperature of the power battery are obtained, and then the current current of the power battery is obtained. Then, the SOC value of the battery can be obtained by using the Kalman filter method and the ampere-hour integration method. The quotient of the cumulative discharge energy of the battery and the total capacity of the battery can be calculated to obtain the number of cycles. Then, according to the correspondence table between the number of cycles and the battery SOH value provided by the battery supplier, the SOH value of the battery is obtained. Secondly, the relationship between the current current, voltage, temperature, etc. of the battery can be used to obtain the current battery charging and discharging power prediction, the power prediction of renewable energy in the next period, and other preprocessing results, thereby obtaining the first data.
[0041] Optionally, in step S10, obtaining the second data may include the following execution steps:
[0042] Step S104: Statistical analysis of the travel characteristics of the target user is performed to obtain statistical results. The travel characteristics of the target user include the time period during which the target user drives the vehicle and the number of times the target user charges and discharges the target vehicle.
[0043] Step S105: Obtain the second data based on the statistical results.
[0044] The second set of data mentioned above could be the target charge / discharge capacity and the desired charge / discharge time period for the user's electric vehicle. The target user could be a user driving an electric vehicle.
[0045] For example, analyzing the charging characteristics of new energy passenger vehicle users can be done by statistically analyzing data such as the user's annual single-trip mileage, single-trip duration, daily trip frequency, daily charging time distribution, and daily charging / discharging frequency. These statistical results can then be analyzed to obtain analytical results, and finally, secondary data can be derived based on these results. Specifically, statistical results could include an average single-trip mileage of 20.1km, an average daily trip frequency of 2.59 trips, an average daily trip duration of 1.9 hours, and 63% of users charging their electric vehicles between 10:00 PM and 6:00 AM. Analytical results could also show that users have more frequent short-distance, short-duration trips on weekends, where short distances can be less than or equal to 10km and short durations can be less than or equal to 30 minutes. Furthermore, analytical results could show a higher frequency of trips lasting 0-120 minutes on weekdays and weekends, with peak charging times around 10 PM.
[0046] It should be noted that the target charge level can be determined by the user settings. If the user does not set a target charge level, the target charge level is 100% and the target charge level is 40%.
[0047] Optionally, in step S12, determining the charge / discharge power information based on the target dataset may include the following steps:
[0048] Step S121: Construct the target model based on the target dataset;
[0049] Step S122: Determine the charge and discharge power information based on the target model.
[0050] The target model mentioned above can be an energy management model. The charge / discharge power information mentioned above can be a charge / discharge power information table.
[0051] Based on the above steps S121 to S122, the total capacity of the battery, the current SOC value of the battery, the current SOH value of the battery, the charging and discharging time period, the target capacity, the grid electricity price, etc. are first determined by the battery parameters, the user's behavior analysis results, and the information transmitted by the power supplier. Then, an energy management model is constructed based on the above information. Finally, a charging and discharging power information table is generated according to the energy management model to determine the charging and discharging power.
[0052] Optionally, in step S121, constructing the target model based on the target dataset may include the following execution steps:
[0053] Step S1211: Perform arithmetic operations on a portion of the first data and the second data to obtain a first intermediate result and a second intermediate result. The first intermediate result is used to represent the amount of electricity consumed by the target vehicle during charging and discharging within a preset time period, and the second intermediate result is used to represent the time required for the target vehicle to charge and discharge within the preset time period.
[0054] Step S1212: Multiply the first intermediate result and the third data to obtain the third intermediate result, wherein the third intermediate result is used to represent the cost incurred by the target user for charging and discharging the target vehicle within a preset time period.
[0055] Step S1213: Calculate the minimum value of multiple second intermediate results to obtain the first calculation result;
[0056] Step S1214: Calculate the minimum value of multiple third intermediate results to obtain the second calculation result;
[0057] Step S1215: Construct the target model based on the first and second calculation results.
[0058] Specifically, the calculation of the first intermediate result is shown in the following formula (1):
[0059] q = P Ri -I chi *V iave *S+I disi *V iave *S Formula (1)
[0060] In formula (1), q represents the amount of electricity consumed by the target vehicle during charging and discharging within a preset time period, and P Ri I represents the renewable energy generation capacity in the i-th time period. chi I represents the charging current of the battery in the i-th time period. disi V represents the discharge current of the battery in the i-th time period. iave Let represent the average voltage of the battery in the i-th time period, and S represent the number of batteries in the battery pack.
[0061] In addition, the charging current and discharging current of the battery in the i-th time period are calculated as shown in the following formula (2):
[0062]
[0063]
[0064] In formula (2), V imax T represents the maximum voltage of the battery in the i-th time period. imax This represents the maximum temperature of the battery in the i-th time period. Indicates the battery charge / discharge derating efficiency, SOH i This represents the SOH value of the battery in the i-th time period.
[0065] The calculation of the second intermediate result is shown in the following formula (3):
[0066]
[0067] In formula (3), t represents the time required for the target vehicle to charge and discharge within a preset time period, and SOC... i This represents the battery's charge level in the i-th time period, where the battery's charge level in the i-th time period is greater than the battery's initial charge level, and the battery's charge level in the i-th time period is less than the target charge level.
[0068] The calculation of the third intermediate result is shown in the following formula (4):
[0069] f = p(i) * (P Ri -I chi *V iave *S+I disi *V iave *S) Formula (4)
[0070] In formula (4), f represents the cost incurred by the target user for charging and discharging the target vehicle within a preset time period, and p(i) represents the grid electricity price.
[0071] The calculation of the first result is shown in the following formula (5):
[0072]
[0073] In formula (5), H represents the shortest time required for the target vehicle to charge and discharge within multiple preset time periods.
[0074] The second calculation result is calculated as shown in the following formula (6):
[0075]
[0076] In formula (6), F represents the minimum cost incurred by the target user for charging and discharging the target vehicle over multiple preset time periods.
[0077] Based on the above steps S121 to S122, by calculating the amount of electricity consumed by the target vehicle during charging and discharging in a preset time period, the charging current and discharging current of the battery in the i-th time period, and the time required for the target vehicle to charge and discharge in the preset time period, the shortest time required for the target vehicle to charge and discharge in multiple preset time periods and the lowest cost incurred by the target user for charging and discharging the target vehicle in multiple preset time periods can be obtained, thereby constructing an energy management model.
[0078] Optionally, in step S122, determining the charge / discharge power information based on the target model may include the following steps:
[0079] Step S1221: Generate the first charge / discharge power information based on the target model;
[0080] Step S1222: Compare the maximum power value in the first charge / discharge power information with the power threshold in the second charge / discharge power information to obtain the comparison result;
[0081] Step S1223: Determine the charging and discharging power information based on the comparison results.
[0082] The power threshold in the second charge / discharge power information is determined by the battery supplier. The result can be either that the maximum power value in the first charge / discharge power information is less than the power threshold in the second charge / discharge power information, or that the maximum power value in the first charge / discharge power information is greater than or equal to the power threshold in the second charge / discharge power information.
[0083] Based on the above steps S1221 to S1223, a first charge and discharge power information table is first generated according to the energy management model. Then, the maximum power value in the first charge and discharge power information is compared with the power threshold in the second charge and discharge power information. When the maximum power value in the first charge and discharge power information is less than the power threshold in the second charge and discharge power information, the power in the first charge and discharge power information is determined as the final charge and discharge power. When the maximum power value in the first charge and discharge power information is greater than or equal to the power threshold in the second charge and discharge power information, the power threshold in the second charge and discharge power information is determined as the final charge and discharge power.
[0084] Figure 2 This is a flowchart of an optional method for determining battery charge and discharge power according to the present invention, such as... Figure 2 As shown, the process first inputs battery parameters, user behavior analysis results, and information transmitted by the power supplier. Then, it calculates the shortest time required for the target vehicle to charge and discharge within multiple preset time periods, as well as the minimum cost incurred by the target user for charging and discharging the target vehicle within the same preset time periods. Next, it constructs an energy management model and generates first charge and discharge power information based on the model. Then, it compares the maximum power value in the first charge and discharge power information with the power threshold in the second charge and discharge power information. Finally, it outputs the charge and discharge power based on the comparison results.
[0085] In addition, in step S14, the power supply circuit installed in the target vehicle is controlled to supply power according to the charging and discharging power information. The power supply circuit may include a power battery system, an energy management system, a DC-DC converter, an energy storage converter, a switch, and a power grid, thereby realizing the power exchange between the power battery and the power supplier.
