Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0041] The following combination Figures 1 to 4 The present invention describes a battery pack control method, a battery pack, a vehicle, an electronic device, and a storage medium.
[0042] According to the embodiment of the first aspect of the present application, see Figure 1 and Figure 2 The battery pack includes a battery 1 and a BMS module 2 electrically connected in sequence; the battery pack control method includes:
[0043] Step 101: Obtain the operating current of the BMS module 2;
[0044] It is understandable that the BMS module 2 is usually powered by the battery 1, so the operating current of the BMS module 2 is obtained so that the operating current of the BMS module 2 will not be omitted when the SOC value of the battery 1 is subsequently determined, thereby ensuring the accuracy of the obtained SOC value of the battery 1.
[0045] For example, the operating current of the BMS module 2 can be directly detected using a current detection component, or the operating current of the BMS module 2 can be determined based on the power consumption and voltage of the BMS module 2. It should be noted that this is only an example of how to obtain the operating current of the BMS module 2 and does not impose any special limitation.
[0046] Step 102 : Determine the SOC value of the battery 1 based on the charge and discharge current of the battery 1 and the operating current of the BMS module 2 .
[0047] It is understandable that the power consumption of the BMS module 2 will affect the SOC of the battery 1. Therefore, the SOC value of the battery 1 is calculated and determined based on the sum of the charge and discharge current of the battery 1 and the operating current of the BMS module 2. The influence of the power consumption of the BMS module 2 on the SOC value of the battery 1 will not be omitted, thereby ensuring the accuracy of the SOC value of the battery 1.
[0048] For example, the charge and discharge current of the battery 1 may be collected by the current collection element Shunt.
[0049] For example, the SOC value of the battery 1 may be determined by an ampere-hour integration method based on the charge and discharge current of the battery 1 and the operating current of the BMS module 2 .
[0050] According to the battery pack control method of the embodiment of the present application, the operating current of the BMS module 2 is first obtained, and then the charge and discharge current of the battery 1 and the operating current of the BMS module 2 are used to perform calculations to determine the SOC value of the battery 1. This ensures that the power consumption effect of the BMS module 2 is not omitted when calculating the SOC value of the battery 1. Compared to calculating the SOC value of the battery 1 using only the charge and discharge current of the battery 1, the present application can avoid the calculation deviation of the SOC value of the battery 1 caused by not taking into account the power consumption of the BMS module 2, which is conducive to improving the accuracy of the SOC value of the battery 1.
[0051] It is understandable that in related technologies, when calculating and determining the SOC value of battery 1, it is generally based on the charge and discharge current of battery 1. However, BMS module 2 is powered by battery 1, which means that BMS module 2 also consumes the power of battery 1. Therefore, when calculating the SOC value using only the charge and discharge current of battery 1, the influence of BMS module 2 is omitted, which in turn causes the calculated SOC value to fail to truly reflect the status of battery 1. The present application obtains the operating current of BMS module 2 when calculating the SOC value of battery 1, performs an ampere-hour integration based on the operating current of BMS module 2 and the charge and discharge current of battery 1, and determines the SOC value of battery 1 based on the result of the ampere-hour integration, thereby ensuring the accuracy of the obtained SOC value of battery 1 and avoiding deviations between the detected SOC value of battery 1 and the actual SOC value of battery 1.
[0052] For example, in the related art, the battery management system BMS of 12V lithium batteries usually uses AFE to collect current in order to save costs and improve the accuracy of current collection. However, some AFE chips do not support the collection of the power consumption of the BMS module 2 itself, and the power source of the BMS is usually battery 1. Since the collected current value lacks board power consumption, the Ah integral calculation is too small and the SOC is too small. However, the present application obtains the operating current of the BMS module 2 before performing the Ah integral calculation, and uses the operating current of the BMS module 2 and the AFE collected current together to perform the Ah integral calculation to ensure the accuracy of the obtained SOC value.
[0053] In some embodiments, the step of obtaining the operating current of the BMS module 2 includes:
[0054] Based on the power consumption and operating voltage of the BMS module 2 , the operating current of the BMS module 2 is determined.
[0055] It is understandable that when obtaining the operating current of the BMS module 2, the operating current of the BMS module 2 can be calculated based on the power consumption and operating voltage of the BMS module 2, so as to facilitate the subsequent accurate calculation of the SOC value of the battery 1.
[0056] In some examples, the power consumption and operating voltage of the BMS module 2 may be directly detected by a detection element.
[0057] In some examples, the power consumption of the BMS module 2 can be determined based on factors such as the operating mode of the BMS module 2, the operating mode of the battery 1, and environmental parameters. For example, a mapping relationship between the power consumption of the BMS module 2 and at least one of the aforementioned influencing factors can be established in advance, and the power consumption of the BMS module 2 can be directly determined based on the influencing factors.
[0058] In some embodiments, before the step of determining the operating current of the BMS module 2 based on the power consumption and operating voltage of the BMS module 2 , the following steps are included:
[0059] Determining the power consumption of the BMS module 2 based on the operating mode of the BMS module 2 and the first database;
[0060] The first database includes power consumption data of the BMS module 2 when the BMS module 2 is in different working modes.
[0061] It is understandable that a first database containing the relationship between each operating mode and the corresponding power consumption of the BMS module 2 is pre-established. According to the identified operating mode of the BMS module 2, the first database is called to perform a table lookup operation to determine the power consumption of the BMS module 2.
[0062] Exemplarily, when establishing the first database, the voltage of the power supply providing power to the BMS is fixed at 12V±5mV.
[0063] It can be understood that this application converts complex operating current calculations into pattern recognition and table lookup operations by establishing a mode-power consumption mapping database, which reduces the dependence on high-precision ADC compared to traditional continuous current monitoring solutions.
[0064] It should be noted that since the power consumption of the BMS changes very little during stable operation, the power consumption data under different operating modes can be calibrated in advance. When calculating the SOC, the power consumption corresponding to the BMS module 2 is added to the Ah integral to increase the accuracy of the SOC calculation.
[0065] Exemplarily, the operating modes include at least: a standby mode, a charging mode, a discharging mode, a balancing mode, a fault diagnosis mode, and the like.
[0066] In some embodiments, based on the operating mode of the BMS module 2 and the first database, the step of determining the power consumption of the BMS module 2 includes:
[0067] Get the temperature of BMS module 2;
[0068] determining power consumption data of the BMS module 2 based on the temperature of the BMS module 2, the operating mode of the BMS module 2, and the first database;
[0069] The first database includes power consumption data of the BMS module 2 in different working modes and at different temperatures.
[0070] It is understandable that when the BMS module 2 is at different temperatures and different operating modes, the power consumption data of the BMS module 2 may be different, that is, the temperature and operating mode will affect the detection of the power consumption data of the BMS module 2. Therefore, when determining the power consumption data of the BMS module 2, the current temperature and current operating mode of the BMS module 2 are obtained, and the current temperature and current operating mode are compared with the first database to obtain the power consumption data of the BMS module 2, thereby realizing the detection of the power consumption data of the BMS module 2 and avoiding the influence of temperature on the detection of the power consumption data of the BMS module 2.
[0071] In some examples, when establishing the first database, the BMS module 2 is placed in different operating modes and at different temperatures, and the power consumption of the corresponding BMS module 2 is detected. After obtaining the detection data, the detection data is filtered to generate power consumption data for different operating modes in different temperature ranges. After removing outliers from the detection data, the average value is calculated. For example, during the BMS MCU sleep period, the BMS board power consumption is typically less than 1mA. Since the power consumption is too low, it is not included in the power consumption statistics.
[0072] It is understandable that the power consumption of the BMS module 2 is significantly affected by temperature (e.g., semiconductor device leakage current increases with temperature, and heat dissipation device power consumption increases). By incorporating temperature as an independent variable into the database, dynamic compensation of power consumption data can be achieved, improving calculation accuracy.
[0073] For example, the first database adopts a hierarchical storage structure of "operating mode → temperature → power consumption". The data range is first narrowed down through pattern recognition, and then specific values are matched according to temperature to reduce the amount of real-time calculations.
[0074] In some embodiments, the battery pack includes a detection element for detecting the power consumption of the BMS module 2 ; before the step of determining the operating current of the BMS module 2 based on the power consumption and operating voltage of the BMS module 2 , the method includes:
[0075] Based on the detection data of the detection element, the power consumption of the BMS module 2 is determined.
[0076] It is understandable that before determining the operating current of the BMS module 2 based on the power consumption and operating voltage of the BMS module 2, the power consumption of the BMS module 2 can be detected by a detection element to obtain the power consumption data of the BMS module 2, so as to facilitate the subsequent calculation of the operating current based on the power consumption and operating voltage of the BMS module 2.
[0077] In some examples, the detection element is, for example, a high-precision current sensor or a power detection chip.
[0078] In some embodiments, the step of obtaining the operating current of the BMS module 2 includes:
[0079] determining an operating current of the BMS module 2 based on the operating mode of the BMS module 2 and the second database;
[0080] The second database includes operating current data of the BMS module 2 in different operating modes.
[0081] It can be understood that since the second database includes the operating current data of the BMS module 2 in different operating modes, when obtaining the operating current of the BMS module 2, the operating mode of the BMS module 2 can be compared with the second database to determine the operating current of the BMS module 2, thereby obtaining the operating current of the BMS module 2.
[0082] It is understandable that by establishing a preset correspondence between operating modes and currents through the second database, the indirect calculation link of "power consumption → voltage → current" in related technologies is skipped, achieving rapid matching of current data. The dynamic current demand of BMS module 2 is discretized into static data under typical operating modes, and the deterministic characteristics of pattern recognition (such as the balancing circuit enable signal) are used to replace complex real-time monitoring, reducing the system's computational load.
[0083] In some examples, a second database containing different operating modes of the BMS module 2 and corresponding operating current data can be established in advance, and the typical current values under each operating mode can be recorded through experimental measurement or theoretical modeling. The operating modes include at least: standby mode, charging mode, discharging mode, balancing mode, fault diagnosis mode, etc.
[0084] The BMS main control unit analyzes the module's operating status signals to determine the current operating mode. For example, the charge / discharge mode is determined by detecting the charge / discharge control signal of battery 1, the balancing mode is determined by reading the balancing circuit enable signal, and the fault diagnosis mode is triggered by receiving a fault code or diagnostic instruction.
[0085] In some embodiments, based on the operating mode of the BMS module 2 and the second database, the step of determining the operating current of the BMS module 2 includes:
[0086] Get the temperature of BMS module 2;
[0087] determining operating current data of the BMS module 2 based on the temperature of the BMS module 2, the operating mode of the BMS module 2, and the second database;
[0088] The second database includes operating current data of the BMS module 2 in different operating modes and at different temperatures.
[0089] It is understandable that when the BMS module 2 is at different temperatures and in different operating modes, the operating current data of the BMS module 2 may be different, that is, the temperature and operating mode will affect the detection of the operating current data of the BMS module 2. Therefore, when determining the operating current data of the BMS module 2, the current temperature and current operating mode of the BMS module 2 are obtained, and the current temperature and current operating mode are compared with the second database to obtain the operating current data of the BMS module 2, thereby realizing the detection of the operating current data of the BMS module 2 and avoiding the influence of temperature on the detection of the operating current data of the BMS module 2.
[0090] In some examples, a second database may be pre-established, containing operating current data of the BMS module 2 in different operating modes and at different temperatures, for example, by recording typical current values of each operating mode in different temperature ranges through experimental measurements or theoretical modeling.
[0091] In some embodiments, the battery pack includes a current detection element, which is used to detect the operating current of the BMS module 2. The step of obtaining the operating current of the BMS module 2 includes:
[0092] Based on the detection data of the current detection element, the operating current of the BMS module 2 is determined.
[0093] It is understandable that when obtaining the operating current of the BMS module 2, the operating current of the BMS module 2 can be detected by the current detection component to obtain the operating current data of the BMS module 2, so as to facilitate the subsequent calculation of the SOC value of the battery 1 based on the operating current data of the BMS module 2.
[0094] In some examples, the current detection element is, for example, a Hall effect current sensor or an integrated current detection chip.
[0095] In some examples, current detection devices are physically connected in series in the BMS power supply circuit to directly sense the current signal based on electromagnetic induction (Hall effect) or Ohm's law (shunt resistance), achieving "inference-free" measurement and eliminating errors caused by pattern misjudgment or database bias in traditional solutions.

[0097] According to the battery pack of the embodiment of the present application, when in use, the operating current of the BMS module 2 can be first obtained, and then the charge and discharge current of the battery 1 and the operating current of the BMS module 2 can be used to perform an ampere-hour integral calculation to determine the SOC value of the battery 1. This ensures that the power consumption effect of the BMS module 2 is not omitted when calculating the SOC value of the battery 1. Compared to calculating the SOC value of the battery 1 using only the charge and discharge current of the battery 1, the present application can avoid the calculation deviation of the SOC value of the battery 1 caused by not taking into account the power consumption of the BMS module 2, which is conducive to improving the accuracy of the SOC value of the battery 1.

[0099] In a vehicle according to an embodiment of the present application, the operating current of the BMS module 2 can be first obtained, and then the charge and discharge current of the battery 1 and the operating current of the BMS module 2 can be used to perform an ampere-hour integral calculation to determine the SOC value of the battery 1.
