[0064] To make the technical solution and advantages of this application clearer, the embodiments of this application will be described in further detail below.

[0065] The terms "first," "second," "third," and "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0066] It should be noted that all information (including but not limited to user equipment information, user personal information, etc.), data (including but not limited to data used for analysis, stored data, displayed data, etc.), and signals involved in this application are authorized by the user or fully authorized by all parties, and the collection, use, and processing of related data must comply with the relevant laws, regulations, and standards of the relevant countries and regions. For example, the discharge current, SOC, etc. involved in this application were obtained with full authorization.

[0067] In some embodiments, the SOC display method provided in this application is performed by an electric vehicle. The electric vehicle can be any vehicle powered by electricity. Optionally, the electric vehicle can be a sedan, truck, bus, or other vehicle, etc., and this application does not limit the scope.

[0068] Figure 1 This is a flowchart of a SOC display method provided in an embodiment of this application. See also... Figure 1 The method is performed by an electric vehicle and includes:

[0069] 101. Electric vehicles obtain the discharge current of the electric vehicle's battery.

[0070] This battery is used to power an electric vehicle. In some embodiments, the battery is also used to provide other electrical support for the electric vehicle. The discharge current refers to the current output by the battery when the electric vehicle is running.

[0071] In this embodiment of the application, when the battery of the electric vehicle is working, the electric vehicle can obtain the output current of the battery when it is working, that is, the discharge current of the battery.

[0072] 102. When the discharge current indicates that the electric vehicle's battery is in a high-power discharge state, the electric vehicle detects the remaining charge of the battery to obtain the first SOC.

[0073] In this context, a high-power discharge state refers to a state where the battery provides a high amount of electrical energy per unit time, and the stored electrical energy decreases rapidly. In this embodiment, if the electric vehicle determines that its battery is in a high-power discharge state based on the discharge current, it indicates that the battery's State of Charge (SOC) is fluctuating significantly. Therefore, it is necessary to detect the remaining battery charge to obtain the first SOC, and subsequently determine the SOC that the electric vehicle needs to display based on this first SOC.

[0074] 103. The electric vehicle acquires a second SOC, which is the SOC displayed by the electric vehicle at the previous moment.

[0075] 104. If the first SOC and the second SOC meet the adjustment conditions, the electric vehicle adjusts the second SOC to obtain the third SOC.

[0076] The adjustment condition is used to indicate the relationship between the first SOC and the second SOC, so as to adjust the second SOC. In some embodiments, the adjustment condition is also used to indicate the manner in which the second SOC is adjusted.

[0077] In this embodiment of the application, after the electric vehicle obtains the first SOC and the second SOC, it determines how to adjust the second SOC to obtain the third SOC by determining the size relationship between the first SOC and the second SOC.

[0078] 105. Electric vehicle displays the third SOC.

[0079] In this embodiment of the application, after the electric vehicle adjusts the second SOC to obtain the third SOC, the third SOC is the SOC that conforms to the SOC change law, and the electric vehicle can display the obtained third SOC.

[0080] In the solution provided in this application embodiment, if the discharge current of the electric vehicle indicates that the battery is in a high-power discharge state, it means that the battery's SOC may jump. Therefore, the SOC that the electric vehicle needs to display at the current moment is determined based on the detected battery SOC and the SOC displayed by the electric vehicle at the previous moment, so as to prevent the SOC from jumping and ensure the stability of the displayed SOC.

[0081] Figure 2 This is a flowchart of a SOC display method provided in an embodiment of this application. See also... Figure 2 The method is performed by an electric vehicle and includes:

[0082] 201. Electric vehicle: Obtain the discharge current of the electric vehicle's battery.

[0083] In some embodiments, the electric vehicle includes a current sensor that detects the current output by the battery to obtain a discharge current. Optionally, after detecting the discharge current, the current sensor also determines whether the discharge current is valid. If the current sensor outputs a discharge current, it indicates that the discharge current is valid; if the current sensor outputs an error message, it indicates that the discharge current is invalid.

[0084] Optionally, the discharge current of the electric vehicle's battery may be the bus current or other current that can indicate the battery's discharge current; this application embodiment does not limit the specific current.

[0085] 202. When the discharge current is valid and the discharge current is greater than the current threshold, the electric vehicle determines that the discharge current indicates that the electric vehicle's battery is in a high-power discharge state.

[0086] In this embodiment, when the discharge current is valid, the state of the electric vehicle's battery can be determined based on the discharge current. If the discharge current is invalid, the state of the electric vehicle's battery cannot be determined based on the discharge current. If the discharge current is greater than the current threshold, it indicates that the electric vehicle's battery is discharging rapidly and the electric vehicle has a high demand for electrical energy. Therefore, it can be determined that the discharge current indicates that the electric vehicle's battery is in a high-power discharge state.

[0087] In some embodiments, when the discharge current is valid and the discharge current is not greater than a current threshold, it is determined that the discharge current indicates that the battery of the electric vehicle is not in a high-power discharge state.

[0088] It should be noted that this embodiment uses step 202 as an example for illustration. In another embodiment, the electric vehicle can also use other methods to determine whether the electric vehicle's battery is in a high-power discharge state, and this embodiment does not limit this method.

[0089] 203. When the discharge current indicates that the electric vehicle's battery is in a high-power discharge state, the electric vehicle detects the remaining charge of the battery to obtain the first SOC.

[0090] In some embodiments, the remaining charge of the battery is detected using any one of the open-circuit voltage method, the ampere-hour integration method, or the internal resistance method to obtain the first SOC.

[0091] 204. The electric vehicle acquires a second SOC, which is the SOC displayed by the electric vehicle at the previous moment.

[0092] In this embodiment of the application, the SOC displayed by the electric vehicle will change, and the electric vehicle will also determine the SOC that needs to be displayed at the current time based on the SOC displayed at the previous moment. Therefore, the electric vehicle will determine the SOC displayed at the previous moment as the third SOC.

[0093] In some embodiments, the electric vehicle updates and displays the State of Charge (SOC) at regular intervals, thus allowing the electric vehicle to obtain the SOC displayed at the previous moment. For example, the electric vehicle updates and displays the SOC every 1 minute, or every 2 minutes; this application embodiment does not limit the scope. Taking the example of the electric vehicle displaying the SOC every 1 minute, the SOC obtained by the electric vehicle from one minute ago is the second SOC.

[0094] 205. When the first SOC is not less than the second SOC, the electric vehicle determines that the first SOC and the second SOC satisfy the adjustment conditions.

[0095] In this embodiment, after the electric vehicle acquires a first SOC and a second SOC, it determines whether the first SOC and the second SOC meet the adjustment conditions by comparing their magnitudes. If the first SOC is not less than the second SOC, it indicates that the detected battery SOC is greater than the SOC displayed at the previous moment, and the battery SOC has increased.

[0096] 206. If the change in the second SOC is less than the change in the first SOC, the electric vehicle will determine the difference between the changes in the second SOC and the first SOC as the third SOC.

[0097] The change in the second SOC refers to the difference between the displayed SOC at the previous moment and the second SOC. For example, if the second SOC is 50% and the SOC at the previous moment is 49%, the change in the second SOC is -1%. If the second SOC is 50% and the SOC at the previous moment is 51%, the change in the second SOC is 1%.

[0098] The first SOC change value may be a change value generated according to a preset rule, or a change value specified for an electric vehicle, or a change value set in other ways; this application embodiment does not limit the specific value.

[0099] In this embodiment, if the first SOC is determined to be not less than the second SOC by step 205, then the relationship between the change in the second SOC and the change in the first SOC is determined to decide which change value to use to adjust the second SOC. If the change in the second SOC is less than the change in the first SOC, it indicates that the change in SOC indicated by the change in the second SOC is small. Therefore, the change in the second SOC is used to adjust the second SOC, and the difference between the two changes in the second SOC is determined as the third SOC. For example, if the change in the second SOC is 1% and the second SOC is 50%, then the third SOC is 49%; if the change in the second SOC is -1% and the second SOC is 50%, then the third SOC is 51%.

[0100] It should be noted that this application uses 206 as an example for illustration. In another embodiment, when the change value of the second SOC is not less than the change value of the first SOC, the difference between the change values ​​of the second SOC and the first SOC is determined as the third SOC.

[0101] In this embodiment, if the first SOC is determined to be not less than the second SOC by step 205, then the relationship between the change in the second SOC and the change in the first SOC is determined to decide which change value to use to adjust the second SOC. If the change in the second SOC is not less than the change in the first SOC, it indicates that the change in SOC indicated by the change in the first SOC is small. Therefore, the change in the first SOC is used to adjust the second SOC, and the difference between the change in the second SOC and the change in the first SOC is determined as the third SOC. For example, if the change in the first SOC is 1% and the second SOC is 50%, then the third SOC is 49%; if the change in the first SOC is -1% and the second SOC is 50%, then the third SOC is 51%.

[0102] In another embodiment, the second SOC is adjusted based on the difference between the first SOC and the SOC detected in the battery at the previous moment, and the first rate of decline, to obtain the third SOC.

[0103] In this embodiment, if the first SOC is determined to be not less than the second SOC by step 205, then the product of the difference and the first descent rate is obtained, and the difference between the second SOC and the product of the first descent rate is determined as the third SOC. The first descent rate can be 0.4, 0.6, or other values; this embodiment does not limit the specific values.

[0104] In some embodiments, the step of determining the first SOC change value includes: obtaining a fourth SOC, where the fourth SOC is the SOC obtained by detecting the remaining battery power at the previous moment; and determining the first SOC change value as the product of the difference between the fourth SOC and the first SOC and a first value. For example, if the fourth SOC is 40% and the first SOC is 35%, then the difference between the first SOC and the fourth SOC is 5%, and the first value is 0.5, so the product of the difference and the first value is 2.5%. The first value can be 0.5, 0.6, or other values, and this embodiment is not limited thereto.

[0105] It should be noted that the first SOC change value in this application embodiment is limited. Optionally, if the product of the difference between the first SOC and the fourth SOC and the first value is greater than the first SOC threshold, the first SOC threshold is determined as the first SOC change value. For example, the first SOC threshold can be 2%, 3%, or other values, which are not limited in this application embodiment. If the fourth SOC is 40% and the first SOC is 35%, then the difference between the first SOC and the fourth SOC is 5%, the first value is 0.5, the product of the difference and the first value is 2.5%, and the first SOC threshold is 2%, indicating that the first SOC change value is 2%.

[0106] It should be noted that steps 205-206 of this application are optional steps. In another embodiment, the following steps can also be performed: if the first SOC is less than the second SOC, determine that the first SOC and the second SOC meet the adjustment conditions; if the first SOC is greater than the difference between the second SOC and the change value of the second SOC, determine the first SOC as the third SOC.

[0107] In this embodiment, if the first SOC is less than the second SOC, it indicates that the detected battery SOC is less than the SOC displayed by the electric vehicle. Furthermore, if the first SOC is greater than the difference between the second SOC and the change in the second SOC, it indicates that the change in the first SOC does not exceed the minimum change in the second SOC. Therefore, the first SOC is determined as the third SOC. For example, if the first SOC is 45%, the second SOC is 50%, and the difference between the second SOC and the change in the second SOC is 44%, then the first SOC is greater than this difference, and 45% is determined as the third SOC.

[0108] It should be noted that steps 205-206 of this application are optional steps. In another embodiment, the following steps can also be performed: if the first SOC is not greater than the difference between the second SOC and the change value of the second SOC, determine that the first SOC and the second SOC meet the adjustment conditions; if the change value of the second SOC is less than the change value of the second SOC, determine the difference between the change values ​​of the second SOC and the change value of the second SOC as the third SOC.

[0109] If the first SOC is not greater than the difference between the second SOC and the change in the second SOC, it means the first SOC is less than the SOC adjusted based on the change in the second SOC. In this case, the relationship between the changes in the second SOC and the change in the second SOC is determined to decide which change value to use for adjustment. If the change in the second SOC is greater than the change in the second SOC, it means the change in SOC indicated by the change in the second SOC is small. Therefore, the change in the second SOC is used for adjustment, and the difference between the two changes in the second SOC is determined as the third SOC. For example, if the change in the second SOC is 1% and the second SOC is 50%, then the third SOC is 49%; if the change in the second SOC is -1% and the second SOC is 50%, then the third SOC is 51%.

[0110] Alternatively, if the first SOC is not greater than the difference between the second SOC and the change in the second SOC, the first SOC and the second SOC are determined to meet the adjustment conditions. If the change in the second SOC is not greater than the change in the second SOC, the difference between the second SOC and the change in the second SOC is determined as the third SOC.

[0111] In this embodiment, if the first SOC is not greater than the difference between the second SOC and the change in the second SOC, then the magnitude relationship between the change in the second SOC and the change in the second SOC is determined, and thus, which change value is used to adjust the second SOC. If the change in the second SOC is not greater than the change in the second SOC, it indicates that the SOC change indicated by the change in the second SOC is small. Therefore, the change in the first SOC is used to adjust the second SOC, and the difference between the change in the second SOC and the change in the first SOC is determined as the third SOC. For example, if the change in the first SOC is 1% and the second SOC is 50%, then the third SOC is 49%; if the change in the first SOC is -1% and the second SOC is 50%, then the third SOC is 51%.

[0112] Alternatively, if the first SOC is not greater than the difference between the second SOC and the change in the second SOC, it is determined that the first SOC and the second SOC meet the adjustment conditions. Based on the difference between the first SOC and the SOC detected in the battery at the previous moment and the first rate of decline, the second SOC is adjusted to obtain the third SOC.

[0113] In this embodiment, if the first SOC is not greater than the difference between the second SOC and the change in the second SOC, then the difference between the first SOC and the SOC detected by the battery at the previous moment is obtained, and the product of this difference and the first rate of decline is obtained. The difference between the product of the second SOC and the first rate of decline is determined as the third SOC. The first rate of decline can be 0.4, 0.6, or other values; this embodiment does not limit the specific values.

[0114] Optionally, the method for obtaining the second SOC change value includes: obtaining a fourth SOC, where the fourth SOC is the SOC obtained by detecting the remaining battery power at the previous moment, and determining the second SOC change value by multiplying the difference between the fourth SOC and the first SOC with the second value.

[0115] In this embodiment, the steps for obtaining the second SOC change value are similar to those in the above embodiments, except that the first value and the second value are different. This embodiment will not be described again.

[0116] It should be noted that the first SOC change value in this application embodiment is limited. Optionally, if the product of the difference between the fourth SOC and the first SOC and the second value is greater than the second SOC threshold, the second SOC threshold is determined as the second SOC change value. For example, the second SOC threshold can be 2%, 3%, or other values, which are not limited in this application embodiment. If the fourth SOC is 40% and the first SOC is 35%, then the difference between the first SOC and the fourth SOC is 5%, the first value is 0.5, the product of the difference and the first value is 2.5%, and the second SOC threshold is 2%, indicating that the second SOC change value is 2%.

[0117] It should be noted that, in this embodiment, the adjustment method for the second SOC is determined by judging the relationship between the first SOC and the second SOC, and then the adjustment of the second SOC is determined based on the determined relationship, so as to complete the adjustment of the second SOC.

[0118] 207. Electric vehicle displays the third SOC.

[0119] In the solution provided in this application embodiment, if the discharge current of the electric vehicle indicates that the battery is in a high-power discharge state, it means that the battery's SOC may jump. Therefore, the SOC that the electric vehicle needs to display at the current moment is determined based on the detected battery SOC and the SOC displayed by the electric vehicle at the previous moment, so as to prevent the SOC from jumping and ensure the stability of the displayed SOC.

[0120] Furthermore, the embodiments of this application determine the state of the electric vehicle's battery based on the magnitude of the discharge current and the current threshold, ensuring the accuracy of the determined state of the electric vehicle's battery.

[0124] The acquisition module 301 is further configured to acquire a second SOC, wherein the second SOC is the SOC displayed by the electric vehicle at the previous moment;

[0125] The adjustment module 303 is used to adjust the second SOC to obtain a third SOC when the first SOC and the second SOC meet the adjustment conditions.
