[0002] Hybrid vehicles currently available in the domestic and international automotive markets are typically HEV / PHEV models, utilizing typical power-type or half-power cells. These cells are characterized by small pack capacity, low ampere-hours, and a small number of cells, resulting in a low reserve of battery power during use. During vehicle use, such as during continuous discharge driving at low temperatures and low SOC, the battery will operate closely within a battery power mode with a higher power limit to ensure smooth vehicle starting and driving. The lack of a strategy for controlling battery power limits results in large and rapid fluctuations in cell voltage, impacting driving experience and easily causing cell voltage to exceed limits, leading to failures and compromising cell life and safety.

[0025] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0026] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically separate entities. That is, these functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0027] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, while others may be combined or partially combined. Therefore, the actual execution order may vary depending on the actual situation.

[0028] In this application, "plurality" refers to two or more. "And / or" describes the relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0029] In the related art, hybrid vehicles currently available in the domestic and international automotive markets are typically HEV / PHEV models, using typical power-type or half-power cells. These cells have the characteristics of small battery pack capacity, low ampere-hours, and a small number of cells. This results in a small reserve of battery power during use. Even with a high current rate for HEV cells, the power headroom is relatively small. This results in the battery operating in a high power mode to ensure smooth vehicle starting and driving, such as during continuous discharge driving or charging at low temperatures and low SOC, charging at high SOC, and discharging at low SOC. The lack of a strategy for battery power limits results in large and rapid changes in cell voltage, affecting the driving experience and easily causing the cell voltage to exceed the limit, leading to failure and damaging the cell life and safety. Alternatively, long-term use of a battery power mode corresponding to continuous power will fail to realize the peak power capacity of the battery cell, failing to tap into the potential of the vehicle's overall power performance.

[0030] To solve the above problems, the embodiments of the present application propose a battery power switching method and device, an electronic device, and a computer-readable storage medium, which mainly relate to the battery control management technology included in hybrid vehicle technology. These embodiments will be described in detail below.

[0031] First see Figure 1 , Figure 1 1 is a schematic diagram of an implementation environment involved in this application, which includes a terminal 10 and a battery management system 20, which communicate with each other via a wired or wireless network.

[0032] The battery management system 20 is used to obtain the first power value of the battery in the historical time period, and obtain the second power value of the battery at the current time point; calculate based on the first power value and the second power value to obtain the battery power operation frequency parameter value; based on the battery power operation frequency parameter value, determine the battery operation frequency results for multiple battery power modes in the historical time period; based on the operation frequency results, switch the battery power mode corresponding to the battery at the current time point, and then control the operating status of the terminal 10 through the battery in the switched battery power mode. It should be noted that Figure 1 The terminal 10 in the illustrated implementation environment may be any type of power supply device including a device with a small-capacity battery, such as a hybrid vehicle, etc., and is not limited here.

[0033] Figure 2 This is a flow chart of a method for switching battery power according to an exemplary embodiment of the present application. Figure 1 The implementation environment shown and Figure 1The method is specifically implemented by the battery management system 20 in the embodiment shown. In other implementation environments, the method may be implemented by devices in other implementation environments, and this embodiment does not limit this.

[0034] like Figure 2 As shown, in an exemplary embodiment, the battery power switching method may include steps S201 to S204, which are described in detail as follows:

[0035] Step S201 : obtaining a first power value of the battery in a historical time period, and obtaining a second power value of the battery at a current time point.

[0036] A device equipped with a battery as a driving device will record and store various information about the battery and the device during operation. The battery power switching method provided in the present application uses the recorded storage information related to the battery power to form a first power value of the battery in a historical time period and a second power value of the battery at the current time point. The first power value and the second power value are obtained for subsequent calculations and the battery power mode corresponding to the battery at the current time point is switched according to the calculation results, without increasing any hardware costs.

[0037] Step S202: Calculate based on the first power value and the second power value to obtain a battery power operating frequency parameter value.

[0038] Due to the needs of the operating conditions, the battery power mode in which the battery is located will switch according to the needs. Each battery power mode will control the battery power at a different target power, causing the battery power value to change. In this embodiment, the first power value is the battery power-related stored information of the battery in the historical time period, and the second power value is the battery power-related stored information at the current time point. Therefore, this application calculates based on the first power value and the second power value to obtain the battery power operating frequency parameter value, where the battery power operating frequency parameter value can represent the battery operating frequency of the battery in the historical time period and at the current time point for each battery power mode.

[0039] Step S203 : determining the operating frequency results of the battery for multiple battery power modes within a historical time period based on the battery power operating frequency parameter value.

[0040] After calculating the battery power operating frequency parameter value reflecting the operating frequency of the battery power mode based on the first power value and the second power value, it is necessary to analyze and process the battery power operating frequency parameter value to determine the operating frequency results of the battery for multiple battery power modes within a historical time period, so as to facilitate switching the battery power mode corresponding to the current time point.

[0041] Step S204 : switching the battery power mode corresponding to the battery at the current time point based on the operating frequency result.

[0042] The operating frequency result can directly represent the operating frequency of the battery for multiple battery power modes within a historical time period. In order to avoid the battery power running in one battery power mode for a long time, which affects the battery safety and user experience, this embodiment switches the battery power mode corresponding to the current time point based on the operating frequency result, thereby strategically adjusting the battery power dynamically.

[0043] As can be seen from the above, in the method provided in this embodiment, the battery power operating frequency parameter value is obtained by calculating the first power value and the second power value, and then the operating frequency result representing the operating frequency of the battery for multiple battery power modes in the historical time period is obtained, which serves as the switching basis for the battery power mode corresponding to the current time point, thereby dynamically controlling the battery power in real time and realizing flexible regulation of the battery power.

[0044] That is, the first power value within the historical time period and the second power value at the current time point are statistically analyzed and processed in real time. When the operating frequency of the battery power mode in which the battery power is located deviates between multiple battery power modes, it is smoothly switched and transitioned between the various battery power modes to keep it near the optimal power required by the current working conditions, maximizing the power potential of small-capacity batteries. At the same time, it also avoids the occurrence of power abuse. For example, when the power of the battery at the current time is very close to the target power corresponding to a battery power mode, the change in the battery power mode causes the target power that the battery power needs to approach to change. In this way, when there is a large difference between the target power before the change and the target power that needs to be approached, it will cause a sudden change in battery power, which will cause the whole vehicle to stall. It also causes the battery cell voltage to exceed the limit and report a fault for a long time, which in turn causes forced high power reduction, causing a fault and damaging the battery cell life and safety.

[0045] In the battery power switching method provided in the present application, the defined first power value and second power value include the same type of data, but the difference is that they correspond to data at different time points. Specifically, in another exemplary embodiment before the present application, the first power value includes the historical power and the first power limit corresponding to multiple time points in the historical time period, and the second power value includes the actual power and the second power limit at the current time. After obtaining the historical power and actual power corresponding to each time, the corresponding first power limit and the second power limit are obtained based on the historical power and the actual power, that is, the power and the power limit are in a matching relationship, and the first power limit and the second power limit refer to the power limit configured for the corresponding battery power mode. Please refer to Figure 3 , Figure 3 yes Figure 2 In the flowchart of step S202 in the illustrated embodiment, in an exemplary embodiment, a plurality of battery power operating frequency parameter values ​​are obtained based on specific data content included in the first power value and the second power value.

[0046] like Figure 3 As shown, step S202 may specifically include steps S301 to S303. The battery power operating frequency parameter value is obtained through the above steps, which are described in detail as follows:

[0047] Step S301: Calculate based on the first power limit and the second power limit to obtain a first operating frequency parameter and a second operating frequency parameter corresponding to a historical time period.

[0048] In all the embodiments provided in this application, the implemented battery power switching method is explained by taking two battery power modes as an example, such as a battery power mode with peak power and a battery power mode with continuous power, wherein peak power refers to the maximum power that the battery can reach in a short time, and continuous power refers to the output power that allows the battery to operate continuously for a long time under the environmental conditions specified by the current relevant standards.

[0049] Therefore, to determine the frequency with which the battery operated in the two battery power modes during a historical time period, after obtaining multiple first power limit values ​​corresponding to multiple time points during the historical time period and the second power limit value at the current time point, a calculation is performed based on the first power limit values ​​and the second power limit values ​​to obtain a first operating frequency parameter corresponding to the battery power mode with peak power and a second operating frequency parameter corresponding to the battery power mode with continuous power. It should also be noted that the implementation condition of the battery power switching method provided in this application is that the actual power at the current time point is greater than the continuous power.

[0050] Step S302 : Calculate based on the historical power, the actual power, the first power limit, and the second power limit to obtain a third operating frequency parameter corresponding to the current time point.

[0051] While obtaining the first operating frequency parameter and the second operating frequency parameter for reference, it is also necessary to calculate the third operating frequency parameter corresponding to the battery power in the historical time period. The third operating frequency parameter corresponds to the actual battery power mode of the battery in the historical time period. Therefore, when calculating the third operating frequency parameter, it is necessary to base it on multiple historical powers corresponding to multiple time points in the historical time period and the actual power at the current time point to clarify the changes in battery power in the historical time period.

[0052] Step S303: Use the first operating frequency parameter, the second operating frequency parameter, and the third operating frequency parameter as battery power operating frequency parameter values ​​respectively.

[0053] Since in subsequent method steps, the operating frequency results of the battery for multiple battery power modes within a historical time period are determined based on the battery power operating frequency parameter value, after obtaining the first operating frequency parameter, the second operating frequency parameter, and the third operating frequency parameter, the first operating frequency parameter, the second operating frequency parameter, and the third operating frequency parameter are directly used as the battery power operating frequency parameter values, respectively.

[0054] In this embodiment, after obtaining the first operating frequency parameter, the second operating frequency parameter, and the third operating frequency parameter, the first operating frequency parameter and the second operating frequency parameter are used as a reference to obtain the relationship between the third operating frequency parameter and the first operating frequency parameter and the second operating frequency parameter, so as to determine whether the battery power mode in which the battery was operated in the past historical time period is biased towards the battery power mode with peak power corresponding to the first operating frequency parameter, or the battery power mode with continuous power corresponding to the second operating frequency parameter. That is, the operating frequency of the battery for each battery power mode in the historical time period and at the current time point is characterized by the relationship between the first operating frequency parameter, the second operating frequency parameter, and the third operating frequency parameter. In addition, in this embodiment, the first operating frequency parameter, the second operating frequency parameter, and the third operating frequency parameter are subjected to boundary constraints, that is, the corresponding upper and lower limits are set to prevent data overflow.

[0055] In this way, through the method steps provided in this embodiment, the operating frequency of the battery for each battery power mode within the historical time period and at the current time point can be more accurately characterized by the first operating frequency parameter, the second operating frequency parameter, and the third operating frequency parameter as the battery power operating frequency parameter value, which is beneficial to the switching control of the battery power mode corresponding to the current time point, thereby achieving the purpose of dynamically regulating the battery power.

[0056] In the battery power switching method provided in the present application, the battery power mode corresponds to a power map table. The power map table records the power under different temperature conditions and different battery state of charge (SOC) conditions. Each power value in the table represents two meanings. Taking a specified temperature and SOC condition as an example of a usage condition, on the one hand, under the current conditions, the corresponding power value can be used continuously for the longest time. On the other hand, under the current conditions, the battery's power usage cannot exceed the corresponding power value, that is, the power limit. In the present application, the power map table corresponding to the battery power mode with peak power can be a 10s power map table, and 10s is the maximum continuous usage time; the power map table corresponding to the battery power mode with continuous power can be a 60s power map table, and 60s is the maximum continuous usage time. Each power map table is determined by the temperature and SOC conditions at the same time point.

[0057] Of course, the power map tables corresponding to the battery power mode with peak power and the battery power mode with continuous power are not limited to the 10s power map table and the 60s power map table. Here, this application uses the 10s power map table and the 60s power map table only to facilitate the explanation of the content of the provided battery power switching method, and is not intended to make specific limitations.

[0058] See also Figure 4 , Figure 4 yes Figure 2 The step of obtaining the first power value in step S201 in the embodiment shown is a flow chart in an exemplary embodiment. Figure 3 As shown, it may specifically include steps S401 to S402, which are described in detail as follows:

[0059] Step S401: Obtain battery operating parameters corresponding to multiple time points within a recorded historical time period.

[0060] In order to obtain multiple first power values ​​of the battery at multiple time points within a historical time period, the corresponding battery operating parameters recorded in the system are obtained for each time point. The battery operating parameters can be the temperature and soc of the battery at multiple time points, or other data that can be used to find a matching first power value from a preset battery operating power mapping table. Again, no specific restrictions are imposed.

[0061] Step S402: obtaining a first power value matching the battery parameters based on the battery operating parameters and a preset battery operating power mapping table; wherein the preset battery operating power table is pre-set with multiple battery operating parameters and first power values ​​corresponding to the multiple battery operating parameters.

[0062] The preset battery operating power mapping table in this application refers to the above-mentioned 10s power map table and 60s power map table. The power map table is a three-dimensional chart formed by power limit, temperature and SOC, that is, the preset battery operating power table is preset with multiple battery operating parameters and first power values ​​corresponding to multiple battery operating parameters. The first power value obtained in this way includes the first limit value of the 10s power map table matched by the battery operating parameters, and the second limit value of the 60s power map table matched by the battery operating parameters.

[0063] In addition, the second power value at the current time point is obtained through the above-mentioned method steps. Specifically, after obtaining the battery operating parameters corresponding to the current time point, the battery operating parameters are used to search the 10s power map table and the 60s power map table as the preset battery operating power mapping table to obtain a second power limit value that matches them. The second power value includes the third limit value of the 10s power map table that matches the battery operating parameters, and the fourth limit value of the 60s power map table that matches the battery operating parameters.

[0064] Therefore, through the method of this embodiment, based on the battery operating parameters of multiple time points within the historical time period and the current time point and the preset battery operating power mapping table, a first power value and a second power value matching the battery parameters are obtained to implement the battery power switching method provided in this application.

[0065] See also Figure 5 , Figure 5 yes Figure 3 Step S301 in the illustrated embodiment is a flowchart in an exemplary embodiment. In this embodiment, the first power limit is a first power limit corresponding to multiple time points within a historical time period, each first power limit including a first limit for a first power spectrum and a second limit for a second power spectrum; the second power limit is a second power limit corresponding to the current time point, including a third limit for the first power spectrum and a fourth limit for the second power spectrum. The first power spectrum is the 10s power map table described above, and the second power spectrum is the 60s power map table.

[0066] like Figure 5 As shown, step S301 may specifically include steps S501 to S503. Through the above steps, the first operating frequency parameter and the second operating frequency parameter corresponding to the historical time period are obtained, which are described in detail as follows:

[0067] Step S501 : performing a difference operation on a first limit value and a second limit value at the same time point to obtain first difference values ​​corresponding to multiple time points.

[0068] For multiple time points within the historical time period, a difference operation is performed on the first limit value and the second limit value of each time point to obtain multiple first difference values ​​corresponding to the multiple time points.

[0069] Step S502 : performing a difference operation on the third limit value and the fourth limit value to obtain a second difference value corresponding to the current time point.

[0070] For the current time point, the third limit value and the fourth limit value are subjected to a difference operation to obtain a second difference value corresponding to the current time point.

[0071] Step S503 : performing an integration operation based on the second difference and the first differences corresponding to the multiple time points to obtain a first operating frequency parameter and a second operating frequency parameter.

[0072] After obtaining the second difference and multiple first differences corresponding to multiple time points in the historical time period, they are integrated to obtain the first operating frequency parameter corresponding to the battery power mode with peak power and the second operating frequency parameter corresponding to the battery power mode with continuous power, that is, the first operating frequency parameter corresponding to the 10s power map table and the second operating frequency parameter corresponding to the 60s power map table.

[0073] In this way, through the method steps provided in this embodiment, the first operating frequency parameter and the second operating frequency parameter are obtained for reference comparison with the third operating frequency parameter, and then the operating frequency of the battery for each battery power mode in the historical time period and at the current time point is more accurately characterized by the first operating frequency parameter, the second operating frequency parameter and the third operating frequency parameter as the battery power operating frequency parameter value, which is beneficial to the switching control of the battery power mode corresponding to the current time point, thereby achieving the purpose of dynamically regulating the battery power.

[0074] See also Figure 6 , Figure 6 yes Figure 5 The flowchart of step S503 in the illustrated embodiment in an exemplary embodiment. In this embodiment, after obtaining the first operating frequency parameter, the second operating frequency parameter, and the third operating frequency parameter in the present application, it is necessary to use the first operating frequency parameter and the second operating frequency parameter as a reference to obtain the relationship between the third operating frequency parameter and the first operating frequency parameter and the second operating frequency parameter, so as to determine whether the battery power mode of the battery operation in the past historical time period is biased towards the battery power mode with peak power corresponding to the first operating frequency parameter, or the battery power mode with continuous power corresponding to the second operating frequency parameter.

[0075] In addition, the power map corresponding to the battery power mode with peak power in this application can be a 10s power map, and 10s is the longest usage time for continuous use; the power map corresponding to the battery power mode with continuous power can be a 60s power map, and 60s is the longest usage time for continuous use, that is, the first power spectrum below is the above-mentioned 10s power map, and the second power spectrum is the 60s power map.

[0076] Therefore, in this embodiment of the present application, in order to obtain the first operating frequency parameter corresponding to the 10s power map table and the second operating frequency parameter corresponding to the 60s power map table, the longest continuous use time of each battery power mode is used as a variable. In this way, the historical time period includes a first time period corresponding to the first power spectrum and a second time period corresponding to the second power spectrum. The first time period is smaller than the second time period. Under the premise that the first power spectrum is a 10s power map table and the second power spectrum is a 60s power map table, the first time period is 10s and the second time period is 60s. In this way, multiple first differences corresponding to multiple time points are obtained through the first time period and the second time period, thereby obtaining the first operating frequency parameter and the second operating frequency parameter.

[0077] like Figure 6 As shown, step S503 may specifically include steps S601 to S602. The first operating frequency parameter and the second operating frequency parameter are obtained through the above steps, which are described in detail as follows:

[0078] Step S601 : performing an integration operation on the second difference and the first difference corresponding to a plurality of time points in the first time period to obtain a first operating frequency parameter.

[0079] For the 10s power map table of the first power spectrum, the first difference corresponding to multiple time points in the first time period is obtained and then integrated with the second difference, that is, at the current time point, the first difference is backtracked according to the time length of 10s of the first time period. After backtracking to obtain the first difference corresponding to multiple time points, the second difference and the multiple first differences are integrated to obtain the first operating frequency parameter corresponding to the 10s power map table.

[0080] Step S602 , performing an integration operation on the second difference and the first difference corresponding to multiple time points in the second time period to obtain a second operating frequency parameter.

[0081] For the second power spectrum 60s power map table, obtain the first difference corresponding to multiple time points in the second time period and then perform an integration operation with the second difference, that is, at the current time point, trace the first difference according to the time length of the second time period 60s. After tracing back to obtain the first difference corresponding to multiple time points, integrate the second difference and multiple first differences to obtain the second operating frequency parameter corresponding to the 60s power map table.

[0082] In this embodiment, the longest usage time of each of the 10s power map table and the 60s power map table is used as a variable for obtaining the first difference to obtain a first operating frequency parameter corresponding to the 10s power map table and a second operating frequency parameter corresponding to the 60s power map table. The first operating frequency parameter and the second operating frequency parameter can then be used as a reference to obtain a relationship between the third operating frequency parameter and the first operating frequency parameter and the second operating frequency parameter, thereby determining whether the battery power mode of the battery operation in the past historical time period is biased towards the battery power mode with peak power corresponding to the first operating frequency parameter or the battery power mode with continuous power corresponding to the second operating frequency parameter, which is beneficial to controlling the switching of the battery power mode corresponding to the current time point.

[0083] See also Figure 7 , Figure 7 yes Figure 3 Step S302 in the illustrated embodiment is a flowchart in an exemplary embodiment. In this embodiment, the first power limit is a first power limit corresponding to multiple time points within a historical time period, each first power limit including a first limit for a first power spectrum and a second limit for a second power spectrum; the second power limit is a second power limit corresponding to the current time point, including a third limit for the first power spectrum and a fourth limit for the second power spectrum. The first power spectrum is the 10s power map table described above, and the second power spectrum is the 60s power map table.

[0084] Depend on Figure 5 It can be seen that in Figure 5 In the illustrated embodiment, the process for obtaining the first and second operating frequency parameters involves performing a difference operation on the first and second limit values ​​at the same time point to obtain the first difference value corresponding to multiple time points. The third and fourth limit values ​​are then subjected to a difference operation to obtain the second difference value corresponding to the current time point. Finally, an integration operation is performed based on the second difference value and the first differences corresponding to multiple time points to obtain the first and second operating frequency parameters. In other words, the limit values ​​corresponding to the first power spectrum at multiple time points within the historical time period and at the current time point are subjected to a difference operation with the limit values ​​corresponding to the second power spectrum, and the resulting differences are integrated.

[0085] Therefore, in this embodiment, in order to make the first operating frequency parameter, the second operating frequency parameter and the third operating frequency parameter as the battery power operating frequency parameter values ​​have a scientific reference, the limit value corresponding to the second power spectrum is used as a quantity, and what changes in the calculation formula is the current actual power of the battery and the historical power of the battery in the historical time period, so as to more accurately obtain the situation in which the third operating frequency parameter corresponds to the actual battery power mode of the battery in the historical time period.

[0086] like Figure 7 As shown, step S302 may specifically include steps S701 to S702. The third operating frequency parameter corresponding to the current time point is obtained through the above steps, which is described in detail as follows:

[0087] Step S701 , performing a difference operation on the historical power and the second limit at the same time point to obtain a plurality of third difference values, and performing a difference operation on the actual power and the fourth limit to obtain a fourth difference value.

[0088] For multiple time points within the historical time period, the historical power and the second limit value at each time point are respectively subtracted to obtain multiple third difference values ​​corresponding to the multiple time points; for the current time point, the historical power and the fourth limit value are subtracted to obtain the second difference value corresponding to the current time point.

[0089] Step S702 : performing an integration operation on the plurality of third differences and the fourth difference to obtain a third operating frequency parameter.

[0090] After obtaining the fourth difference and a plurality of third differences corresponding to a plurality of time points in the historical time period, they are integrated to obtain a situation that can reflect the actual battery power mode of the battery in the historical time period.

[0091] By comparing the third operating frequency parameter with the first operating frequency parameter and the second operating frequency parameter, the operating frequency of the battery for the first power spectrum and the second power spectrum in the historical time period can be obtained, and the bias of the battery power mode can be clarified.

[0092] As can be seen from the above, in the method provided in this embodiment, the third operating frequency parameter is obtained by using multiple historical powers corresponding to multiple time points in the historical time period and the actual power at the current time point as variables in the calculation formula, combined with the limit values ​​corresponding to the second power spectrum at the same time point. This enables the first operating frequency parameter and the second operating frequency parameter to be used as references to obtain the relationship between the third operating frequency parameter and the first operating frequency parameter and the second operating frequency parameter, respectively, so as to determine whether the battery power mode of the battery operation in the past historical time period is biased towards the battery power mode with peak power corresponding to the first operating frequency parameter or the battery power mode with continuous power corresponding to the second operating frequency parameter, which is beneficial for controlling the switching of the battery power mode corresponding to the current time point.

[0093] See also Figure 8 , Figure 8 yes Figure 2 The flowchart of step S203 in the embodiment shown is in an exemplary embodiment. Figure 8 As shown, step S203 may specifically include steps S801 to S803, which are described in detail as follows:

[0094] Step S801 : obtaining a fifth difference between the third operating frequency parameter and the first operating frequency parameter, and obtaining a sixth difference between the third operating frequency parameter and the second operating frequency parameter.

[0095] The method of respectively obtaining the relationship between the third operating frequency parameter and the first operating frequency parameter and the second operating frequency parameter is specifically to obtain a fifth difference between the third operating frequency parameter and the first operating frequency parameter, and to obtain a sixth difference between the third operating frequency parameter and the second operating frequency parameter, and to obtain the deviation between the third operating frequency parameter and the first operating frequency parameter and the second operating frequency parameter respectively through the fifth difference and the sixth difference.

[0096] In step S802, if the fifth difference is greater than the sixth difference, an operating frequency result is obtained, which is used to characterize that the frequency of the battery operating in the first battery power mode during the historical time period is greater than the frequency of operating in the second battery power mode; wherein the battery power corresponding to the first battery power mode is greater than the battery power corresponding to the second battery power mode.

[0097] Among them, the first battery power mode corresponds to the above-mentioned first power spectrum 10s power map table, and the second power mode corresponds to the above-mentioned second power spectrum 60s power map table. The power limit of the 10s power map table is the peak power, and the power limit of the 60s power map table is the continuous power. The peak power of the same battery must be greater than the continuous power. Therefore, the battery power corresponding to the first battery power mode is greater than the battery power corresponding to the second battery power mode.

[0098] Because the power limit matches the historical power or actual power of the battery at the same time point, and the second time period is longer than the first time period, the multiple first differences corresponding to the multiple time points in the second time period necessarily include the first differences corresponding to the multiple time points in the first time period. That is, the number of first differences corresponding to the integration operation performed to obtain the second operating frequency parameter is greater than the number of first differences corresponding to the integration operation performed to obtain the first operating frequency parameter. For example, at a time point of 1 second, the integration operation of the second operating frequency parameter corresponds to the second difference and 59 first differences, and the integration operation of the first operating frequency parameter corresponds to the second difference and 9 first differences, and the 9 first differences of the first operating frequency parameter are included in the 59 first differences of the second operating frequency parameter.

[0099] Therefore, it can be seen that the second operating frequency parameter is greater than the first operating frequency parameter. Because the third operating frequency parameter is the integral result of the difference between the battery's historical power and actual power and the power limit of the second power spectrum at the same time point, if the fifth difference between the third operating frequency parameter and the first operating frequency parameter is greater than the sixth difference between the third operating frequency parameter and the second operating frequency parameter, it means that the frequency at which the actual battery power during the historical time period represented by the third operating frequency parameter was greater than the battery power corresponding to the second battery power mode is relatively high. In other words, the frequency at which the battery operated in the first battery power mode during the historical time period was greater than the frequency at which it operated in the second battery power mode, as the operating frequency result.

[0100] The frequency of the first battery power mode or the frequency of the second battery power mode may be determined according to the operation duration or operation times of the battery power mode, or may be determined in other ways, which are not specifically limited here.

[0101] Step S803 : If the fifth difference is less than or equal to the sixth difference, an operating frequency result is obtained, which indicates that the frequency of the battery operating in the second battery power mode is greater than the frequency of the battery operating in the first battery power mode during the historical time period.

[0102] If the fifth difference between the third operating frequency parameter and the first operating frequency parameter is less than or equal to the sixth difference between the third operating frequency parameter and the second operating frequency parameter, it indicates that the frequency at which the actual battery power during the historical time period represented by the third operating frequency parameter was greater than the battery power corresponding to the second battery power mode was relatively low, that is, the frequency at which the battery operated in the second battery power mode during the historical time period was greater than the frequency at which the battery operated in the first battery power mode, as the operating frequency result.

[0103] It should also be noted that since the first operating frequency parameter, the second operating frequency parameter and the third operating frequency parameter are subject to boundary constraints, that is, the corresponding upper limit maximum value and lower limit minimum value are set to prevent data overflow, the first operating frequency parameter, the second operating frequency parameter and the third operating frequency parameter obtained by the integral operation will not increase infinitely. After reaching the set upper limit maximum value, the data is initialized, and the first power value of the battery in the historical time period is obtained again, and the second power value of the battery at the current time point is obtained to implement the battery power switching method provided in this application.

[0104] Therefore, through the method of this embodiment, the present application determines the size relationship between the frequency of operating the first battery power mode and the frequency of operating the second battery power mode in the historical time period through the fifth difference between the third operating frequency parameter and the first operating frequency parameter, and the sixth difference between the third operating frequency parameter and the second operating frequency parameter, so that when the operating frequency of the battery power mode in which the battery power is located is biased among multiple battery power modes, it can be smoothly switched and transitioned between the various battery power modes.

[0105] See also Figure 9 , Figure 9 yes Figure 2 The flowchart of step S204 in the embodiment shown is in an exemplary embodiment. Figure 9 As shown, step S204 may specifically include steps S901 to S902, which are described in detail as follows:

[0106] Step S901: If the operating frequency result indicates that the frequency of the battery operating in the first battery power mode during the historical time period is greater than the frequency of the battery operating in the second battery power mode, the battery power mode corresponding to the current time point is switched to the second battery power mode; wherein the battery power corresponding to the first battery power mode is greater than the battery power corresponding to the second battery power mode.

[0107] Among them, the first battery power mode corresponds to the above-mentioned first power spectrum 10s power map table, and the second power mode corresponds to the above-mentioned second power spectrum 60s power map table. The power limit of the 10s power map table is the peak power, and the power limit of the 60s power map table is the continuous power. The peak power of the same battery must be greater than the continuous power. Therefore, the battery power corresponding to the first battery power mode is greater than the battery power corresponding to the second battery power mode.

[0108] If the operating frequency result indicates that the frequency of the battery operating in the first battery power mode during the historical time period is greater than the frequency of operating in the second battery power mode, it means that the battery power mode operated by the battery during the historical time period is more inclined to the first battery power mode, so the battery power mode corresponding to the current time point is switched to the second battery power mode.

[0109] Step S902 : If the operating frequency result indicates that the battery operates in the second battery power mode more frequently than in the first battery power mode during the historical period, the battery power mode corresponding to the current time point is switched to the first battery power mode.

[0110] If the operating frequency result indicates that the frequency of the battery operating in the second battery power mode during the historical time period is greater than the frequency of operating in the first battery power mode, it means that the battery power mode operated by the battery during the historical time period is more inclined to the second battery power mode, so the battery power mode corresponding to the current time point is switched to the first battery power mode.

[0111] Through the above embodiment, based on the operating frequency results, when it is determined that the operating frequency of the battery power mode in which the battery power is located during the historical time period is biased between multiple battery power modes, it is smoothly switched and transitioned between the various battery power modes to keep it near the optimal power required by the current working conditions, thereby maximizing the power potential of small-capacity batteries. At the same time, it also avoids the occurrence of power abuse. For example, when the power of the battery at the current time is very close to the target power corresponding to a battery power mode, the change in the battery power mode causes the target power that the battery power needs to approach to change. In this way, when there is a large difference between the target power before the change and the target power that needs to be approached, it will cause a sudden change in battery power, which may cause the entire vehicle to stall. In addition, it may cause the battery cell voltage to exceed the limit and report a fault, which in turn may cause forced high power reduction, causing a fault and damaging the battery cell life and safety.

[0112] See also Figure 10 , Figure 10 In an exemplary embodiment of the present application, a flowchart of switching the battery power mode corresponding to the battery at the current time point may include the following steps:

[0113] Step S1001, obtaining the recorded battery operating parameters corresponding to the current time point and multiple time points in the historical time period, and obtaining the actual power P at the current time point;

[0114] Step S1002 , searching for a matching limit value A2 from a 60s power map table based on battery operating parameters;

[0115] Step S1003 , searching for a matching limit value A1 from a 10s power map table based on the battery operating parameters;

[0116] Step S1004: When P is greater than A2, the difference between P and A2 is integrated and counted in chronological order to obtain an integral value Q1;

[0117] Step S1005: The difference obtained by subtracting A2 from A1 is integrated and counted over time to obtain the integral value Q2 of the difference within the past 10 seconds and the integral value Q3 of the difference within the past 60 seconds.

[0118] Step S1006 , switching the battery power mode corresponding to the current time point according to the relationship between the values ​​of Q1, Q2, and Q3;

[0119] Step S1007 : Control the battery to output a final power limit value A3 according to the switched battery power mode.

[0128] In another exemplary embodiment, the processing unit 1103 is further used to obtain a fifth difference between the third operating frequency parameter and the first operating frequency parameter, and to obtain a sixth difference between the third operating frequency parameter and the second operating frequency parameter; if the fifth difference is greater than the sixth difference, an operating frequency result corresponding to the frequency of the battery operating in the first battery power mode during the historical time period is obtained, characterizing that the frequency of the battery operating in the first battery power mode is greater than the frequency of the battery operating in the second battery power mode during the historical time period; wherein the battery power corresponding to the first battery power mode is greater than the battery power corresponding to the second battery power mode; if the fifth difference is less than or equal to the sixth difference, an operating frequency result corresponding to the frequency of the battery operating in the second battery power mode during the historical time period is obtained.

[0129] In another exemplary embodiment, the switching unit 1104 is further used to switch the battery power mode corresponding to the current time point to the second battery power mode if the operating frequency result indicates that the frequency of the battery operating in the first battery power mode during the historical time period is greater than the frequency of operating in the second battery power mode; wherein the battery power corresponding to the first battery power mode is greater than the battery power corresponding to the second battery power mode; if the operating frequency result indicates that the frequency of the battery operating in the second battery power mode during the historical time period is greater than the frequency of operating in the first battery power mode, then the battery power mode corresponding to the current time point is switched to the first battery power mode.
