Description

Technical Field

[0001] This application relates to the field of battery technology, and more specifically, to a battery power regulation method, apparatus, electronic device, and automobile. Background Technology

[0002] The peak discharge power of a battery is its ability to withstand extreme loads. Its advantage is strong real-time output capability, but its duration is short. It is suitable for working conditions that require the battery to have a large output capability for a short time, such as cold start at low temperature or starting with high throttle. However, long-term use may lead to the risk of overcharging and over-discharging.

[0003] A battery's constant discharge power is its ability to withstand a constant load. Its advantage is that it can be sustained for a long time, but its real-time output capability is relatively weak. It is suitable for normal driving conditions and cannot meet the needs of higher power output.

[0004] Existing batteries do not take into account actual usage requirements when reporting peak discharge power and constant discharge power. If only the power reported by one type of battery is used as the usable charge and discharge power, the actual effect cannot meet the usage requirements, resulting in low battery efficiency.

[0027] The power overshoot percentage is obtained based on the discharge overshoot power and the discharge reference difference power.

[0028] The accumulated count is obtained based on the power overshoot percentage and the preset conversion factor.

[0029] In the above implementation process, the accumulated count is obtained based on the overshoot percentage and the preset conversion factor, so that the accumulated count can be adjusted according to the conversion factor, thereby improving the flexibility of battery discharge power adjustment.

Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0057] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0058] Example 1

[0059] Figure 1 This is a schematic flowchart of the battery discharge rate adjustment method provided in the embodiments of this application, as shown below. Figure 1 As shown, the method includes:

[0060] S1, obtain the battery's actual discharge power, constant discharge power, and peak discharge power;

[0061] S2, the discharge overshoot power is obtained based on the actual discharge power and the constant discharge power;

[0062] S3, obtain the discharge reference difference power based on constant discharge power and peak discharge power;

[0063] S4, obtain the cumulative count based on the discharge overshoot power and the discharge reference difference power;

[0064] S5 adjusts the battery's discharge power based on the accumulated count.

[0065] In the above implementation process, the discharge reference difference power and discharge overshoot power are obtained based on the actual discharge power, constant discharge power and peak discharge power. The discharge power of the battery is adjusted according to the reference difference power and discharge overshoot power. The discharge power of the battery can be adjusted in a timely manner, which can improve the battery's efficiency, extend the battery's service life, and save costs and energy consumption.

[0066] In the embodiments of this application, in the initial state, the peak discharge power of the battery is generally preferred as the discharge power.

[0067] In S1, the actual discharge power, constant discharge power, and peak discharge power of the battery are acquired in real time.

[0068] In S2, the discharge overshoot power is calculated using the following formula:

[0069] P DchgOvershoot =P Act -P DchgConst ;

[0070] Among them, P DchgOvershoot For discharge overshoot power, P Act P represents the actual discharge power. DchgConst The discharge power is constant.

[0071] In S3, the discharge reference difference power is calculated using the following formula:

[0072] P DchgDiff =P DchgPeak -P DchgConst ;

[0073] Among them, P DchgDiff P is the discharge reference difference power. DchgConst For constant discharge power, P DchgPeak This represents the peak discharge power.

[0074] Furthermore, S4 includes:

[0075] The discharge power overshoot percentage is obtained based on the discharge overshoot power and the discharge reference power difference.

[0076] The cumulative count is obtained based on the discharge power overshoot percentage and the preset conversion factor.

[0077] In the above implementation process, the accumulated count is obtained based on the overshoot percentage and the preset conversion factor, so that the accumulated count can be adjusted according to the conversion factor, thereby improving the flexibility of battery discharge power adjustment.

[0078] Furthermore, S5 includes:

[0079] The first counting threshold is calibrated based on the battery cell temperature;

[0080] If the accumulated count is greater than or equal to the first count threshold, the constant discharge power is determined as the battery's discharge power.

[0081] In the above implementation process, the first counting threshold is calibrated according to the cell temperature, so that the first counting threshold can be adjusted according to the cell temperature, ensuring that the battery discharge power can be adjusted according to the cell temperature and improving the battery availability.

[0082] When the battery discharge power is adjusted, the cell temperature is initially set to the initial temperature. As time increases, the cell temperature becomes the real-time cell temperature corresponding to each moment of the battery.

[0083] Furthermore, after the step of adjusting the battery's discharge power based on the accumulated count, the method further includes:

[0084] If the actual discharge power is less than the constant discharge power, the remaining discharge power is obtained based on the constant discharge power and the actual discharge power.

[0085] The cumulative count is obtained based on the remaining discharge power and the discharge reference power difference.

[0086] The battery's discharge power is adjusted based on the cumulative count.

[0087] In the above implementation process, the cumulative count is obtained based on the remaining discharge power and the discharge reference power difference, and then the discharge power of the battery is adjusted according to the cumulative count, which can realize multi-dimensional adjustment of the battery's discharge power.

[0088] The remaining discharge power is divided by the discharge reference power difference to obtain the percentage of remaining discharge power. The percentage of remaining discharge power is multiplied by a specific conversion factor and used as the step size of the counter for counting, and finally the cumulative count is obtained.

[0089] The remaining discharge power is calculated using the following formula:

[0090] P DchgRemain =P DchgConst -P Act ;

[0091] Among them, P DchgRemain Remaining discharge power, P DchgConst For constant discharge power, P Act This represents the actual discharge power.

[0092] Furthermore, the step of adjusting the battery's discharge power based on the cumulative count includes:

[0093] Determine whether the cumulative count has reached the second counting threshold;

[0094] If so, the peak discharge power is determined as the discharge power.

[0095] In the above implementation process, the cumulative count is obtained based on the remaining discharge power and the discharge reference power difference, which allows the battery to adjust the discharge power according to different changes, thereby increasing the adjustment range and application dimensions, and improving the battery's service life.

[0096] If the counter decreases from a predetermined value to a second counting threshold, for example, the second counting threshold can be 0, then the peak discharge power is used as the battery's discharge power.

[0097] Furthermore, after the step of adjusting the battery's discharge power based on the accumulated count, the method further includes:

[0098] Obtain the battery's actual charging power, constant charging power, and peak charging power;

[0099] The charging overshoot power is obtained based on the actual charging power and the constant charging power.

[0100] The charging reference difference power is obtained based on the constant charging power and the peak charging power;

[0101] The charging power of the battery is adjusted based on the charging overshoot power and the charging reference power difference.

[0102] In the above implementation process, the charging power of the battery is adjusted, making the adjustment process more flexible and improving the battery's utilization efficiency.

[0103] The same method can be used to adjust the battery's charging power, prioritizing the use of peak charging power.

[0104] To determine whether the actual charging power of the battery exceeds the constant charging power, the overshoot power is calculated. The difference between the peak charging power and the constant charging power is calculated in real time and used as the charging reference difference power. A counter is started to count the overshoot power. The overshoot power is divided by the charging reference difference power to obtain the overshoot percentage, which is then multiplied by a specific conversion factor to obtain the corresponding cumulative count during charging. A first count threshold is calibrated based on the cell temperature. If the corresponding cumulative count during charging is greater than or equal to the first count threshold, the constant charging power is determined as the battery's charging power. If the actual charging power of the battery is less than the constant charging power, the difference between the constant charging power and the actual charging power is calculated as the remaining charging power. The remaining charging power is divided by the charging reference difference power to obtain the remaining charging power percentage, which is then multiplied by a specific conversion factor to obtain the cumulative count during charging. If the cumulative count decreases from a predetermined value to a second count threshold, the peak charging power is used as the battery's charging power.

[0105] In this embodiment, based on the battery's reported available charge and discharge power, the VCU adjusts the constant discharge power, charging power, peak discharge power, and peak charging power in real time according to the ratio between the battery's actual discharge power, actual charging power, constant discharge power, constant charging power, peak discharge power, and peak charging power, as the battery's allowed charging and discharging power.
