Description

TECHNICAL FIELD

[0001] The present application relates to the field of computers, in particular to a method and device for determining a battery power ratio, a storage medium and a processor. BACKGROUND

[0002] At present, the estimation of the SOC of a pure electric vehicle generally uses an open circuit voltage to correct the initial value of the SOC, and then uses the ampere-hour method to update the real-time value and stores the power at power-off, and then uses the open circuit voltage correction value to filter the initial value at power-on. However, in the process of data processing, the current SOC value is directly added or subtracted by the real-time change in power. However, due to the large difference in magnitude between the battery SOC value and the real-time change in power, the maximum value of the SOC in a commercial vehicle can reach 500 Ah, and the real-time change in power, assuming that the current is counted every 0.01 seconds, the minimum accuracy of the current is 0.1 A, and it can also be as low as 0.001 As. Therefore, the battery SOC value and the real-time change in power differ by 12 orders of magnitude. If the current accuracy is improved, the difference between the two orders of magnitude is greater. Therefore, if the battery SOC value and the real-time change in power are directly subtracted to calculate, the requirement for data storage is high, the use of floating-point numbers will lose accuracy, and the use of integer numbers requires 64-bit integers, which occupies a lot of memory, and the accuracy of the determined power ratio is also low.

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiments of the present application, and is not used to limit the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0025] Figure 1 The flowchart of the method for determining the battery power ratio according to the embodiments of the present application is schematically shown. As shown in Figure 1 In an embodiment of the present application, a method for determining a battery power ratio is provided, comprising the following steps:

[0026] Step 101, determining the first remaining power of the battery at the last time.

[0027] In step 102, a cumulative integral value of the battery from a previous time to a current time is determined.

[0028] In step 103, in a case where the cumulative integral value is greater than a preset value, an effective capacity of the battery at the current time is determined according to the cumulative integral value and the preset value.

[0029] In step 104, a capacity ratio of the battery at the current time is determined according to the first remaining capacity and the effective capacity.

[0030] The battery can refer to a battery in a pure electric vehicle. In determining the capacity ratio of the battery, the processor can first determine a first remaining capacity of the battery at a previous time. The first remaining capacity is in units of mAh. Then, the processor can determine a cumulative integral value of the battery from the previous time to the current time. The cumulative integral value is in units of mAs. In a case where the cumulative integral value is greater than a preset value, the processor can determine an effective capacity of the battery at the current time according to the cumulative integral value and the preset value. The preset value can be customized according to actual conditions. For example, the preset value can be 3600. The effective capacity is in units of mAh. In determining the first remaining capacity of the battery at the previous time and the effective capacity at the current time, the processor can determine a capacity ratio of the battery at the current time according to the first remaining capacity and the effective capacity.

[0031] Through the above technical solution, the cumulative integral value of the battery from the previous time to the current time is determined, and when the cumulative integral value reaches the preset value, the capacity ratio of the battery at the current time is determined together with the first remaining capacity at the previous time. The cumulative integral value is used as an intermediate variable, which not only reduces the magnitude of the battery storage, but also avoids the precision error caused by the floating point number, so that the capacity ratio of the battery is more accurate.

[0032] In one embodiment, determining the cumulative integral value of the battery from the previous time to the current time includes: obtaining a historical integral value of the capacity of the battery at the previous time; obtaining the current of the battery every preset time interval starting from the previous time; determining an actual integral value of the capacity of the battery according to the current of the battery in each preset time interval and the total usage time between the previous time and the current time; and determining the sum of the historical integral value and the actual integral value as the cumulative integral value.

[0033] In a case where the battery is not discharging or charging, the vehicle controller of the pure electric vehicle can store the power history integral value at this time. In a case where the battery is discharging or charging, the processor can obtain the power history integral value of the battery at the last time, and can obtain the current of the battery every preset time interval from the last time. The current of the battery can be detected by a current sensor. The current sensor can be installed in the pure electric vehicle. The current sensor can detect the current of the battery at a preset interval. For example, the preset interval can be 0.01s. After the current sensor detects the current of the battery at the preset interval, the current can be sent to the processor, and the processor can obtain the current of the battery every preset time interval. The preset time interval can be 0.01s.

[0034] The processor can determine the actual power integral value of the battery according to the current of the battery in each preset time interval and the total use time between the last time and the current time. Specifically, the processor can integrate each preset time interval and the current of the battery in each preset time interval to obtain the integral value of the battery in each preset time interval. For example, each preset time interval Δt and the current of the battery I in each preset time interval can be multiplied to determine the integral value of the battery in each preset time interval IΔt. Then, the processor can add the integral value of the battery corresponding to each preset time interval included in the total use time to obtain the actual power integral value of the battery. After determining the actual power integral value of the battery corresponding to the last time and the current time, the processor can determine the sum of the power history integral value and the actual power integral value, and can determine the power cumulative integral value of the battery from the last time to the current time.

[0035] In one embodiment, in a case where the power cumulative integral value is greater than the preset value, determining the effective power of the battery at the current time according to the power cumulative integral value and the preset value includes: in a case where the power cumulative integral value is greater than the preset value, determining a first ratio between the power cumulative integral value and the preset value; rounding the first ratio, and determining the rounded first ratio as the effective power.

[0036] In a case where the power cumulative integral value is greater than the preset value, the processor can determine a first ratio between the power cumulative integral value and the preset value. Then, the processor can round the first ratio, and can determine the rounded first ratio as the effective power of the battery at the current time. For example, if the power cumulative integral value is 7800mAs and the preset value is 3600, the first ratio is 2.17mAh. At this time, rounding the first ratio can obtain an effective power of 2mAh.

[0037] In one embodiment, determining the ratio of the battery's power at the current time according to the first residual power and the effective power comprises: determining a second residual power at the current time according to the first residual power and the effective power; determining a second ratio between the second residual power and the battery capacity of the battery as the ratio of the battery's power at the current time.

[0038] After determining the first residual power of the battery at the previous time and the effective power at the current time, the second residual power at the current time can be determined according to the first residual power and the effective power. Then, the processor can further acquire the battery capacity of the battery, and can determine a second ratio between the second residual power and the battery capacity of the battery. The processor can further determine the second ratio as the ratio of the battery's power at the current time.

[0039] In one embodiment, determining the second residual power at the current time according to the first residual power and the effective power comprises: in the case that the battery is in the charging state from the previous time to the current time, determining the sum of the first residual power and the effective power as the second residual power; in the case that the battery is in the discharging state from the previous time to the current time, determining the difference between the first residual power and the effective power as the second residual power.

[0040] The battery can be in the discharging state or the charging state from the previous time. In the case that the battery is in the charging state from the previous time to the current time, the processor can determine the sum of the first residual power and the effective power, and can determine the sum of the power as the second residual power of the battery at the current time. In the case that the battery is in the discharging state from the previous time to the current time, the processor can determine the difference between the first residual power and the effective power, and can determine the difference between the power as the second residual power of the battery at the current time.

[0041] In one embodiment, the method further comprises: determining a power integration difference value between the power cumulative integration value and the product of the preset value and the effective power; recording the power integration difference value in the case that the battery is in the sleep state, and determining the power integration difference value as the power history integration value at the next time.

[0042] After determining the effective power of the battery at the current time, the processor can first determine the product between the effective power and the preset value, and then can further determine the power integration difference value between the power cumulative integration value and the product. After determining the power integration difference value, the processor can further determine whether the battery is in the sleep state. The sleep state can refer to a state in which the battery is not discharged or charged. If the battery is in the sleep state, the power integration difference value can be recorded, and the power integration difference value can be determined as the power history integration value at the next time. That is, when the battery is discharged or charged again, the power history integration value at the next time can be obtained to further determine the power ratio of the battery at the next time. For example, if the power cumulative integration value is 7800mAs, the preset value is 3600, and the effective power is 2mAh, the product between the preset value and the effective power can be first determined as 7200mAs, and then 7800mAs can be subtracted from 7200mAs to determine the power integration difference value as 600mAs.

[0043] In one embodiment, determining the first residual power of the battery at the previous time includes: obtaining the battery capacity of the battery and the power ratio of the battery at the previous time; and determining the product between the battery capacity and the power ratio at the previous time as the first residual power.

[0044] In determining the power ratio of the battery, the processor can first obtain the battery capacity of the battery and the power ratio of the battery at the previous time. Then, the processor can determine the product between the battery capacity and the power ratio at the previous time, and can determine the product as the power ratio of the battery at the previous time.

[0045] In one embodiment, as shown in FIG. 8, another flowchart of a method for determining the power ratio of the battery is provided. Figure 2

[0046] ​Here, VCU can refer to the vehicle controller, and the vehicle can refer to a pure electric vehicle. When determining the battery's charge ratio, the processor first obtains the integrated quantity Qx (the battery's historical integrated charge value at the previous moment) stored in the VCU. When the battery is charging or discharging, the processor acquires the sensor current at current acquisition time intervals Δt, i.e., it acquires the battery current every preset time interval. Here, Δt is the preset time interval, which can be 0.01s. The processor integrates the current over the time interval Δt to determine the real-time change in battery charge, thus determining the actual integrated charge value. The processor adds the stored integrated quantity Qx to the real-time change in battery charge. If the sum (integrated quantity Qx) is greater than 3600, then n can be obtained by rounding Qx to Q1. Here, Q1 is a preset value, which can be 3600, and n is the effective charge. Based on this, the processor determines the historical integrated charge value for the next moment as: integrated quantity Qx - 3600 × n.

[0047] Next, the processor can obtain the initial SOC value (the battery's charge percentage at the previous moment) and battery capacity (the battery's capacity in Ah) corrected using the open-circuit voltage method. The processor can multiply the initial SOC value and battery capacity by 1000 to obtain the current charge Q (the first remaining charge at the previous moment, in mAh). Further, the processor can subtract the current charge Q from n and divide by the total battery capacity Q0 (the battery's capacity in Ah) to obtain the current SOC (the battery's charge percentage at the current moment).

[0048] The above technical solution determines the cumulative integral value of the battery's charge from the previous moment to the current moment. When the cumulative integral value reaches a preset value, it is compared with the first remaining charge at the previous moment to determine the battery's charge ratio at the current moment. Using the cumulative integral value as an intermediate variable not only reduces the amount of battery storage but also avoids the precision error caused by floating-point numbers, making the battery charge ratio more accurate.
