[0002] Hybrid vehicles have become a common mode of transportation in people's daily lives because they can meet the needs of users who use electricity for short distances and gasoline for long distances.
[0003] For hybrid vehicles, the required battery reserve varies depending on the usage scenario, meaning the target balance battery level differs. Currently, the target balance battery level for hybrid vehicles depends on the user's selected driving mode, increasing the learning and operational complexity for users and resulting in lower battery balancing efficiency. Summary of the Invention

[0026] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.
[0027] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.
[0028] This embodiment provides a power balancing method that can be applied to hybrid vehicles, which can be range-extended hybrid vehicles or plug-in hybrid vehicles.
[0029] like Figure 1 As shown, the power balancing method in this application embodiment may include the following steps:
[0030] S101: Obtain the actual battery level of the hybrid vehicle to obtain a first actual battery level value.
[0031] In some embodiments, the actual electrical charge can be expressed as the actual state of charge (SOC). For ease of description, the actual electrical charge can also be expressed as SOCAct.
[0032] Understandably, the actual battery level of a hybrid vehicle changes as the vehicle is driven; therefore, the actual battery level of the hybrid vehicle obtained at different times may differ. The first actual battery level value is the actual battery level obtained in this instance, i.e., the current actual battery level of the hybrid vehicle.
[0033] S102: Obtain the target balance charge of the hybrid vehicle to obtain the first target balance charge value.
[0034] The target balance charge, also known as energy reserve, SOC balance point target, energy balance point, or target value, can be represented as SOCBalTgt for ease of description.
[0035] Hybrid vehicles have different energy reserve requirements depending on the usage scenario or driving mode. For example, in pure electric priority mode, the energy reserve requirement is lower to extend the pure electric range; in fuel priority mode, the energy reserve requirement is higher to improve the vehicle's power performance.
[0036] Based on this, in the embodiments of this application, the target balance charge of the hybrid vehicle can be adaptively adjusted according to the charging frequency of the hybrid vehicle, and the adaptive adjustment can satisfy:
[0037] If a hybrid vehicle is not charged for a long time, the target balance charge can be gradually increased to improve the power performance of the hybrid vehicle.
[0038] Hybrid vehicles have a charging behavior, and the target balance charge can be gradually reduced according to the charging frequency to extend the pure electric range.
[0039] In this embodiment of the application, the current actual charge value of the hybrid vehicle can be compared with a threshold value to determine whether the hybrid vehicle is in the charge depleting (CD) stage or the charge sustaining (CS) stage, and thus determine the charging frequency of the hybrid vehicle.
[0040] It is worth noting that the threshold value is related to the current target balance charge value of the hybrid vehicle. Therefore, the current target balance charge value of the hybrid vehicle, i.e., the first target balance charge value, can be obtained by executing S102, in order to determine a threshold value, i.e., the first threshold value, for comparison with the current actual charge value.
[0041] S103: Compare the first actual power value with the first threshold value to obtain a first comparison result, wherein the first threshold value is the sum of the first target balanced power value and the preset offset value.
[0042] The preset offset value can be set in advance. For ease of description, the preset offset value can be represented as SOCBalOfst.
[0043] The threshold value is used to determine whether the hybrid vehicle is in the CS stage or the CD stage. Since the SOCAct dynamic balance is near SOCBalTgt in the CS stage, in order to improve the reliability of the stage determination of the hybrid vehicle, in this embodiment of the application, the threshold value is the sum of the target balance charge value and the preset offset value, that is, threshold value = SOCBalTgt + SOCBalOfst.
[0044] The first comparison result can be the comparison result between SOCAct and SOCBalTgt + SOCBalOfst, which can include two cases: the first case is that SOCAct ≥ SOCBalTgt + SOCBalOfst, and the second case is that SOCAct... <SOCBalTgt+SOCBalOfst。
[0045] S104: Adjust the target balance charge based on the first comparison result.
[0046] For a detailed implementation of S104, please refer to the following description, which will not be described here.
[0047] In this embodiment, the target balanced power can be adaptively adjusted without user intervention. The adaptive adjustment is performed gradually.
[0048] It should be noted that the adaptive adjustment of the target balance charge in the embodiments of this application can be applied to all driving modes of hybrid vehicles, or it can be applied to a certain driving mode. That is, the target balance charge can also be adaptively adjusted for the corresponding driving mode.
[0049] The battery balancing method provided in this application can first obtain the current actual battery level and the target balanced battery level of the hybrid vehicle before adjusting the target balanced battery level. The sum of the current target balanced battery level and a preset offset value is then used as a threshold value. Afterwards, the current actual battery level can be compared with the threshold value, and based on the comparison result, adaptive adjustment of the balanced battery level can be achieved without user intervention, thereby improving battery balancing efficiency.
[0050] In some embodiments, the target balanced charge is adjusted based on the first comparison result, and the charge balancing method may include:
[0051] If the first comparison result is that the first actual power value is greater than or equal to the first threshold value, the charging status of the hybrid vehicle is obtained.
[0052] Adjust the target balanced charge based on the charging status.
[0053] In this embodiment, SOCAct ≥ SOCBalTgt + SOCBalOfst indicates that the hybrid vehicle is in the CD stage. Since the hybrid vehicle goes through the CD stage regardless of whether it is charging or not, it is impossible to distinguish whether it is a charging vehicle or not. Therefore, the target balance charge can be adjusted by obtaining the charging status of the hybrid vehicle to improve the reliability of the target balance charge adjustment.
[0054] In some embodiments, adjusting the target balanced charge based on the charging state includes at least one of the following:
[0055] When the charging state is not charging, the target balanced power level is maintained at the first target balanced power level value;
[0056] When the charging state is charging, the target balanced power value is adjusted from the first target balanced power value to the second target balanced power value, wherein the second target balanced power value is greater than or equal to the lower boundary value of the target balanced power value and less than the first target balanced power value.
[0057] When the charging state is not charging, since it is impossible to distinguish whether the hybrid vehicle is charging or not, the target balance charge level can be maintained unchanged. Figure 2 ① in the middle.
[0058] When the charging state is "charging," it indicates that the hybrid vehicle is a charging vehicle. This allows for a reduction in the target balance charge level. Specifically, as the charging frequency increases, the target balance charge level is gradually reduced to extend the pure electric range. Figure 2 ④ and ⑤ in the text.
[0059] In this embodiment, the lower boundary value SOCLoBnd and the upper boundary value SOCBalHiBnd of the target balanced charge can be preset. SOCBalHiBnd and SOCLoBnd can be preset by the user; SOCLoBnd can be preset to 20%, and SOCBalHiBnd can be preset to 70% or 60%. When adjusting the target balanced charge based on the charging frequency, it is necessary to ensure that the adjusted target balanced charge value is not less than SOCLoBnd and not greater than SOCBalHiBnd.
[0060] By using the above method, the target balance charge can be adaptively adjusted according to the charging frequency of the hybrid vehicle to meet the power reserve requirements of the hybrid vehicle, thereby improving the reliability of the level balance.
[0061] In some embodiments, the target balanced power value is adjusted from the first target balanced power value to the second target balanced power value. The power balancing method may include:
[0062] Based on the first target balanced power value, the value of the first parameter is determined to be a first value, and the value of the first parameter is positively correlated with the first difference, wherein the first difference is the difference between the first target balanced power value and the lower boundary value;
[0063] Subtract the first value from the first target balanced power value to obtain the second value;
[0064] The target balanced charge value is adjusted from the first target balanced charge value to the second target balanced charge value, wherein the second target balanced charge value is the maximum value between the second value and the lower boundary value.
[0065] The first parameter can be represented as delta. The value of the first parameter can be determined based on the difference between the first target balance point power value and SOCBalLoBnd, i.e., the first difference, or the difference between the first target balance point power value and SOCBalHiBnd, i.e., the second difference, or it can be preset.
[0066] The value of the first parameter is negatively correlated with the first difference; that is, the larger the first difference, the larger the value of the first parameter, and vice versa. Correspondingly, the value of the first parameter is negatively correlated with the second difference; that is, the larger the first difference, the smaller the value of the first parameter, and vice versa.
[0067] In other words, the closer SOCBalTgt is to SOOCLoBnd, the smaller delta is; the closer SOCBalTgt is to SOCHiBnd, the larger delta is.
[0068] In one specific embodiment, the relationship between the value of the first parameter and the first difference can be determined by looking up a table.
[0069] In this embodiment, the second value is obtained by subtracting the first value from the first target balanced power value. To prevent the lowered target balanced power value from being less than the lower boundary value, the second value can be compared with the lower boundary value after obtaining the second value.
[0070] When the second value is greater than the lower boundary value, the second value can be directly determined as the adjusted target balanced energy value. When the second value is less than or equal to the lower boundary value, the lower boundary value can be directly determined as the adjusted target balanced energy value.
[0071] By using the above method, the lowered target balance charge value can be made no less than the lower boundary value, thereby improving the reliability of determining the target balance charge.
[0072] In some embodiments, according to the first comparison result, the target balanced power is adjusted. The power balancing method may include:
[0073] When the first comparison result is that the first actual power value is less than the first threshold value, it is determined that the hybrid vehicle is in the power maintenance stage, and the target information of the hybrid vehicle maintaining in the power maintenance stage is recorded. The target information includes at least one of the duration and the continuous mileage.
[0074] According to the target information, the target balanced power is adjusted.
[0075] When SOCAct < SOCBalTgt + SOCBalOfst, it indicates that the hybrid vehicle is in the CS stage. It is possible to further determine whether the hybrid vehicle is a non-charging vehicle based on the continuous mileage and / or duration in the CS stage, and then adjust the target balanced power to improve the reliability of adjusting the target balanced power.
[0076] In specific implementation, when the first comparison result is that the first actual power value is less than the first threshold value, a timer and a mileage recorder can be started to record the duration and the continuous mileage respectively. At the same time, the steps of S101 - S104 are repeatedly executed until the first actual power value is greater than or equal to the first threshold value, and then the timer and the mileage recorder are stopped. At this time, the duration recorded by the timer is the duration, and the mileage recorded by the mileage recorder is the continuous mileage.
[0077] The target information is used as the basis for adjusting the target balanced power, and the target information includes at least one of the duration and the continuous mileage.
[0078] In some embodiments, adjusting the target balanced power according to the target information may include at least one of the following:
[0079] When the target information does not meet the first condition, the target balanced power is maintained as the first target balanced power value;
[0080] When the target information meets the first condition, the target balanced power is adjusted from the first target balanced power value to a third target balanced power value, and the third target balanced power value is less than or equal to the upper boundary value of the target balanced power and less than or equal to the first target balanced power value.
[0081] Wherein, the first condition includes at least one of the following: the duration is greater than the time threshold; the continuous mileage is greater than the mileage threshold. Correspondingly, the target information may include at least one of the duration and the continuous mileage.
[0082] The first condition may include at least one of the following: the duration is greater than a time threshold, and the duration mileage is greater than a mileage threshold, wherein both the time threshold and the mileage threshold can be preset.
[0083] The duration and mileage of the hybrid vehicle recorded by the timer and odometer during the CS phase are compared with the time threshold and mileage threshold, respectively.
[0084] If the first condition includes the duration being greater than a time threshold and the continuous mileage being greater than a mileage threshold, then both the duration being greater than a time threshold and the continuous mileage being greater than a mileage threshold must be satisfied simultaneously for it to be said that the target information satisfies the first condition.
[0085] If the target information only satisfies one of the following conditions: the duration is greater than the time threshold, or the continuous mileage is greater than the mileage threshold, then the target information does not meet the first condition.
[0086] Therefore, there are two situations regarding the target information: one is that the target information meets the first condition, and the other is that the target information does not meet the first condition. Therefore, for the two situations of the target information, two different methods are adopted to adjust the target balance power.
[0087] If the target information does not meet the first condition, it cannot be concluded that the hybrid vehicle is a charging vehicle. The target equilibrium charge level should remain unchanged. Figure 2 ② in the middle.
[0088] If the target information meets the first condition, it indicates that the hybrid vehicle is a charging vehicle, and the target balance charge can be increased, such as... Figure 2 ③. In specific implementation, the target balanced power is adjusted from the first target balanced power value to the third target balanced power value. The range of the third target balanced power value should be greater than the first target balanced power value and less than or equal to the upper boundary value of the target balanced power.
[0089] In some embodiments, adjusting the target balanced power value from the first target balanced power value to the third target balanced power value may include:
[0090] Based on the first target balanced power value, the value of the second parameter is determined to be the third value, and the value of the third parameter is determined to be the fourth value, wherein the values of the second parameter and the third parameter are positively correlated with the second difference, and the second difference is the difference between the first target balanced power value and the upper boundary value;
[0091] The fifth value is calculated by summing the fifth value with the first target balanced power value to obtain the sixth value, wherein the fifth value is the smaller of the product of the third value and the duration, and the product of the fourth value and the duration mileage;
[0092] The target balanced charge is adjusted from the first target balanced charge value to the third target balanced charge value, wherein the third target balanced charge value is the maximum value between the sixth value and the upper boundary value.
[0093] The second parameter can be represented as k1, and the third parameter can be represented as k2. The values of the second and third parameters can be determined based on the difference between the first target balance point energy value and SOCBalLoBnd, i.e., the first difference, or the difference between the first target balance point energy value and SOCBalHiBnd, i.e., the second difference, or they can be preset.
[0094] The value of the first parameter is negatively correlated with the first difference; that is, the larger the first difference, the smaller the value of the first parameter, and vice versa. Correspondingly, the value of the first parameter is positively correlated with the second difference; that is, the larger the first difference, the larger the value of the first parameter, and vice versa.
[0095] In other words, the closer SOCBalTgt is to SOOCLoBnd, the smaller delta is; the closer SOCBalTgt is to SOCHiBnd, the larger delta is.
[0096] In this embodiment, the product of the second parameter and the duration can be calculated first to obtain the third value, and the product of the third parameter and the duration can be calculated to obtain the fourth value. Then, the smaller of the third and fourth values is determined as the fifth value.
[0097] Then, by adding the fifth value to the first target balanced power value, the sixth value is obtained.
[0098] To avoid the target balanced power value after adjustment not being greater than the upper boundary value, after obtaining the sixth value, the sixth value can be compared with the upper boundary value.
[0099] When the sixth value is less than the upper boundary value, the sixth value can be directly determined as the adjusted target balanced energy value. When the sixth value is less than or equal to the upper boundary value, the upper boundary value can be directly determined as the adjusted target balanced energy value.
[0100] By using the above method, the reduced target balance charge value can be made no greater than the upper boundary value, thereby improving the reliability of determining the target balance charge.
[0101] It should be noted that the various optional embodiments described in the embodiments of the present application can be combined with each other without conflict, or can be implemented separately. The embodiments of the present application do not limit this.
[0102] The following is a specific application example to illustrate the power balance method provided by the embodiments of the present application.
[0103] In the embodiments of the present application, the power balance point (power reserve) can be adaptively adjusted according to the charging frequency of the vehicle:
[0104] If the vehicle does not charge for a long time (in terms of mileage or date), the power reserve is gradually increased, which is beneficial to the power performance;
[0105] If the vehicle has a charging behavior, the power reserve is gradually reduced according to the charging frequency to extend the pure electric mileage.
[0106] The specific adjustment method may include:
[0107] ① When SOCAct > SOCBalTgt + SOCBalOfst, keep SOCBalTgt unchanged;
[0108] ② When SOCAct < SOCBalTgt + SOCBalOfst, but the duration / mileage is short, keep SOCBalTgt unchanged;
[0109] ③ When SOCAct < SOCBalTgt + SOCBalOfst and lasts for a period of time / mileage (time > Tthr and distance > Dthr), SOCBalTgt starts to slowly increase with time / mileage:
[0110] SOCBalTgt = SOCBalTgt + min{k1*Δtime, k2*Δdistance}
[0111] Where k1 and k2 are functions related to the current SOCBalTgt value. When SOCBalTgt is close to SOCLoBnd, the values of k1 and k2 are large; when SOCBalTgt is close to SOCHiBnd, the values of k1 and k2 are small. In specific implementation, it can also be realized by calibration look-up table;
[0112] ④ When plugging in the charging gun and the charging amount is greater than the threshold value, subtract a certain value from SOCBalTgt:
[0113] SOCBalTgt = SOCBalTgt - delta
[0114] Here, delta is similar to k1 and k2 mentioned above, and is also a function related to SOCBalTgt. When SOCBalTgt is close to SOCLoBnd, delta is smaller; when SOCBalTgt is close to SOCHiBnd, delta is larger. In practice, it can also be implemented through calibration lookup tables.
[0115] ⑤ Ultimately, SOCBalTgt is subject to adaptive adjustment within a certain range: SOCBalTgt must not be less than SOCBalLoBnd and must not be greater than SOCBalHiBnd.
[0116] SOCBalTgt=min{max{SOCBalTgt,SOCBalLoBnd},SOCBalHiBnd}.
[0117] The above method can adaptively adjust the battery SOC threshold according to different user charging habits.
