Description

An interface generation method and related device

[0001] The present application claims priority to the Chinese patent application No. 202411037879.7, filed on July 30, 2024, and entitled "An interface generation method and related device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of computer, and in particular, to an interface generation method and related device. BACKGROUND

[0003] The available capacity of a battery gradually decreases as the temperature of the battery decreases. For example, the available capacity of the battery temporarily decreases at low temperature because the electrolyte activity is weakened, and the available capacity of the battery increases when the temperature increases. Because the available capacity of the battery changes, the remaining capacity of the battery or the state of charge (SOC) of the battery needs to be adjusted.

[0004] When the temperature of the battery changes from high temperature to low temperature, the actual available capacity inside the battery is greatly reduced, resulting in that the real available capacity at low temperature is much lower than the available capacity calculated at high temperature before. At this time, if the available capacity calculated at high temperature at the previous moment is displayed, it may cause the battery to be seriously discharged, which brings safety hazards. If the available capacity calculated at the previous moment at high temperature is not displayed, but the available capacity calculated at this moment is displayed, the available capacity may fluctuate greatly and be unstable, which results in poor user experience.

[0079] As shown in FIG. 1, the vehicle 101 comprises a power battery 1011 and a processing device 1012. Of course, the vehicle 101 also comprises devices supporting the vehicle to travel and to be controlled, such as a traveling system, a braking system, etc., which are not shown here. It should be understood that the type of the vehicle shown here is only an example, and in specific implementations, the vehicle 101 can be a car, a truck, a train, a bus, a van, an electric vehicle, or the like. The devices comprised by the vehicle 101 will be described exemplarily as follows.

[0080] The power battery 1011 is a power source providing a power source for the vehicle 101. Optionally, the power battery 1011 can also be a power source providing power for devices in the vehicle 101. Exemplarily, the power battery 1011 can be a ternary lithium battery, a valve-regulated lead-acid battery, an open-top tubular lead-acid battery, or a lithium iron phosphate battery.

[0081] The processing device 1012 has data acquisition capability and data processing capability. Exemplarily, the processing device 1012 can acquire the remaining capacity of the power battery 1011 and the current unavailable capacity of the power battery 1011, and generate a first interface. The first interface is used to indicate the theoretical endurance capability of the vehicle and the lost endurance capability. Optionally, the theoretical endurance capability is related to the remaining capacity, and the lost endurance capability is related to the current unavailable capacity. As shown in FIG. 2A, the first interface comprises a fourth display area for displaying that the theoretical endurance capability of the power battery 1011 is 70%, the lost endurance capability of the power battery 1011 is 20%, and the full-charge endurance capability of the power battery 1011 is 100%. As shown in FIG. 2B, the first interface comprises a fourth display area for displaying that the theoretical endurance capability of the power battery 1011 is 467km, the lost endurance capability of the power battery 1011 is 133km, and the full-charge endurance capability of the power battery 1011 is 667km. The full-charge endurance capability of the power battery is used to indicate the rated capacity of the power battery.

[0082] Optionally, the processing device 1012 can receive data of the power battery 1011 and calculate the remaining capacity of the power battery 1011 and the current unavailable capacity of the power battery 1011, thereby acquiring the remaining capacity of the power battery 1011 and the current unavailable capacity of the power battery 1011. Exemplarily, the processing device 1012 is connected with the power battery 1011, and the processing device 1012 can receive data transmitted (or output) by the power battery 1011 through a connection line therebetween, and calculate the remaining capacity of the power battery 1011 and the current unavailable capacity of the power battery 1011 according to the data of the power battery 1011.

[0083] As a possible implementation, the processing apparatus 1012 can be a physical device, for example, the processing apparatus 1012 can include one or more of the following modules: a central processing unit (CPU), a microprocessor unit (MPU), an application specific-integrated circuit (ASIC), a field programmable gate array (FPGA), a complex programmable logic device (CPLD), a co-processor (assisting the central processing unit to complete corresponding processing and application), a microcontroller unit (MCU), a mobile data center (MDC), and / or an electronic control unit (ECU), etc. Of course, the above is described by taking the processing apparatus 1012 as a vehicle-mounted device as an example, in some schemes, the processing apparatus 1012 can be a physical device arranged outside the vehicle, for example, a server, a cloud, or a host, etc. As a possible implementation, the processing apparatus 1012 can be a software module, for example, a virtual machine, software, program code, or a container, etc.

[0084] Optionally, the vehicle 101 can further include a display apparatus 1013. The display apparatus 1013 has interface display capability. Exemplarily, the display apparatus 1013 is connected with the processing apparatus 1012, and the display apparatus 1013 can receive the first interface sent (or output) by the processing apparatus 1012 through the connection line therebetween, and display the first interface.

[0085] As a possible implementation, the processing apparatus 1012 acquires the residual capacity of the power battery 1011 and the current unavailable capacity of the power battery 1011, and generates a first interface. The residual capacity of the power battery is the capacity difference between the rated capacity of the power battery and the current used capacity of the power battery, the current unavailable capacity of the power battery is related to the current working condition of the power battery, and the first interface is used to indicate the theoretical endurance capability of the vehicle and the lost endurance capability. Optionally, the theoretical endurance capability is related to the residual capacity, and the lost endurance capability is related to the current unavailable capacity. In this way, the theoretical endurance capability is related to the residual capacity, and the residual capacity is irrelevant to the current unavailable capacity. Compared with the prior art, the residual capacity in the present application does not change with the current working condition of the power battery, for example, does not change with the current temperature of the power battery. The present application displays the theoretical endurance capability through the first interface, which can improve the stability of the endurance capability of the power battery, for example, improve the stability of the power of the power battery or the capacity change.

[0086] In addition, in the present application, the lost endurance capability is related to the current unavailable capacity, and the current unavailable capacity is related to the current working condition of the power battery, for example, changes with the current temperature of the power battery. The present application displays the lost endurance capability through the first interface, so that the user can intuitively perceive the lost endurance capability of the power battery, so that the user can more easily understand the current endurance capability of the power battery, and improve the user experience.

[0087] The method of the embodiment of the present application will be described in detail below.

[0088] Please refer to FIG. 3, which is a flowchart of a method for generating an interface according to an embodiment of the present application. Optionally, the method can be applied to a vehicle, for example, to the vehicle 101 shown in FIG. 1, and can be executed by the processing apparatus 1012 in the vehicle 101.

[0089] The method for generating an interface shown in FIG. 3 can include steps S301 and S302. Steps S301 and S302 are as follows:

[0090] Step S301: The processing apparatus acquires the residual capacity of the power battery of the vehicle and the current unavailable capacity of the power battery.

[0091] The processing apparatus is a device with data processing capability. For example, the processing apparatus is the processing apparatus 1012 shown in FIG. 1.

[0092] The residual capacity of the power battery is the capacity difference between the rated capacity of the power battery and the current used capacity of the power battery.

[0093] As a possible implementation, the processing device can obtain the rated capacity of the power battery and the current used capacity of the power battery, and determine the remaining capacity of the power battery according to the rated capacity and the current used capacity. The rated capacity of the power battery refers to all the capacity values that can be discharged by a new full power battery at 25 degrees Celsius according to a preset discharge rate. That is, the rated capacity of the power battery is a fixed value, and the rated capacity of the power battery does not change with the service life of the power battery or the current working condition of the power battery. After the power battery is manufactured, the rated capacity of the power battery is fixed.

[0094] Optionally, the processing device can obtain the rated capacity of the power battery by querying the model of the power battery, and the processing device can obtain the current used capacity of the power battery by using the ampere-hour integration method or the open-circuit voltage method.

[0095] The ampere-hour integration method is a commonly used battery state of charge (SOC) estimation method, which estimates the SOC by accumulating the charge and discharge current of the battery. The basic principle of this method is that if the initial SOC of the battery and the current during charging and discharging are known, the SOC of the battery can be calculated by integration. The calculation formula of the ampere-hour integration method is as follows:

[0096] Wherein, SOC(t) is the state of charge of the battery at time t, SOC(t0) is the state of charge of the battery at time t0, I(t) is the charge and discharge current of the battery at time t, and C is the rated capacity of the battery. Wherein, represents the used capacity of the power battery in the time period (t-t0).

[0097] Optionally, the processing device calculates the state of charge SOC(t) of the power battery at time t according to the above formula (1), and the product of SOC(t) and the rated capacity C is the remaining capacity of the power battery at time t.

[0098] The open-circuit voltage method is a method for determining the characteristics of a battery by measuring the terminal voltage of the battery in an open-circuit state. This method is based on the difference between the electrode potential of the positive electrode and the electrode potential of the negative electrode of the battery when the circuit is open (i.e. when there is no current flowing through the two poles). The basic idea of the open-circuit voltage method is to estimate the state of charge SOC of the battery according to the open-circuit voltage of the battery (i.e. the voltage measured without load). There is a certain relationship between the state of charge SOC of the battery and its open-circuit voltage, and this relationship can be obtained by discharging experiments on the battery.

[0099] Exemplarily, the relationship between the open circuit voltage and the state of charge SOC can be established in advance according to the test data of the open circuit voltage of the battery, for example, a corresponding relationship curve between the open circuit voltage and the state of charge SOC, and the current state of charge SOC of the power battery can be obtained by the processing device according to the corresponding relationship curve, and the product of the current state of charge SOC of the power battery and the rated capacity is the current remaining capacity of the power battery.

[0100] Exemplarily, the processing device obtains that the rated capacity of the power battery is 100 kWh and the current used capacity of the power battery is 30 kWh, and then determines that the remaining capacity of the power battery is the difference between 100 kWh and 30 kWh, that is, 70 kWh.

[0101] The current unusable capacity of the power battery is related to the current working condition of the power battery. Optionally, the current working condition of the power battery includes the current temperature of the power battery, and / or the current battery cycle number of the power battery.

[0102] As a possible implementation, the processing device obtains the current working condition of the power battery, and determines the current unusable capacity of the power battery according to the current working condition of the power battery.

[0103] Exemplarily, the current working condition of the power battery includes the current temperature of the power battery. The processing device can obtain the unusable SOC of the power battery at a certain temperature by looking up the unusable SOC table, and the product of the unusable SOC of the power battery and the rated capacity is the current unusable capacity of the power battery. The unusable SOC table is used to indicate the corresponding relationship between the temperature of the power battery and the unusable SOC. For example, the rated capacity of the power battery is 100 kWh, and the current temperature of the power battery is -10℃. The processing device obtains that the unusable SOC of the power battery at -10℃ is 20% by looking up the unusable SOC table, and the unusable capacity of the power battery at -10℃ is 100 kWh*20%, that is, the current unusable capacity of the power battery at -10℃ is 20 kWh.

[0104] The current battery cycle number of the power battery refers to the cycle number of the power battery from full state to empty state and back to full state. Optionally, the current battery cycle number of the power battery can be accumulated. For example, the power battery is reduced from 100% to 40% and is charged from 40% to 80% and stopped charging, that is, 40% of the power battery is charged in the first charging. The next time the power battery is used, it is reduced from 80% to 20% and is charged from 20% to 100%, that is, 80% of the power battery is charged in the second charging, and the total charging is 120%, and the current battery cycle number of the power battery can be increased by 1.

[0105] For another example, the current operating condition of the power battery includes the current number of battery cycles. For instance, if the theoretical cycle life of the power battery is N cycles resulting in a 20% loss of rated capacity, then the unusable capacity is... Where N is a value obtained from pre-testing, which is related to factors such as the performance of the power battery.

[0106] For another example, the current operating condition of the power battery includes the current temperature and the current number of battery cycles. For instance, if the rated capacity of the power battery is 100 kWh and the current temperature is -10°C, according to the aforementioned information, the processing device looks up the unavailable SOC table and finds that the unavailable capacity of the power battery at -10°C is 20 kWh. At this time, the current number of battery cycles is n, and the processing device calculates the unavailable capacity based on the aforementioned information. The current unavailable capacity of the power battery is:

[0107] Step S302: The processing device generates the first interface.

[0108] The first interface indicates the vehicle's theoretical range and lost range. The theoretical range is related to the remaining capacity, while the lost range is related to the currently unavailable capacity.

[0109] In one possible implementation, the theoretical driving range is the percentage of remaining capacity relative to the rated capacity, and the lost driving range is the percentage of unavailable capacity relative to the rated capacity. For example, if the rated capacity of the power battery is 100kWh, the remaining capacity is 70kWh, and the unavailable capacity is 20kWh, then the theoretical driving range is... Loss of battery life Therefore, the actual usable range is (70% - 20%), which is 50%.

[0110] In another possible implementation, theoretical range is used to indicate theoretical driving distance, which is calculated based on the remaining capacity. Lost range is used to indicate lost driving distance, which is calculated based on the current unavailable capacity of the battery. For example, the processing device can calculate the furthest distance the vehicle can travel using only the remaining charge in the battery, based on the remaining capacity of the battery; this furthest distance is the theoretical driving distance. Even more exemplarily, the processing device can calculate the furthest distance the vehicle can travel in pure electric mode using only the unavailable charge in the battery, based on the current unavailable capacity of the battery; this furthest distance is the lost driving distance.

[0111] For example, the processing device can obtain the theoretical driving range according to the remaining capacity of the power battery divided by the average energy consumption, and obtain the loss driving range according to the current unavailable capacity of the power battery divided by the average energy consumption. For example, the average energy consumption can be the average energy consumption of the vehicle under the world light vehicle test cycle (WLTC) working condition or the average energy consumption under other conditions. For example, the rated capacity of the power battery is 100 kWh, the remaining capacity of the power battery is 70 kWh, the unavailable capacity is 20 kWh, and the average energy consumption of the vehicle is 15 kWh / 100 km. The full-charge driving range of the vehicle is The theoretical driving range of the vehicle is The loss driving range of the vehicle is The theoretical driving range of the vehicle is

[0112] For example, the theoretical driving range is 70%, the loss driving range is 20%, and the first interface is exemplarily illustrated in combination with FIG. 2A, FIG. 4, FIG. 5, FIG. 6 and FIG. 7.

[0113] For example, the theoretical driving range is 70%, the loss driving range is 20%, and the first interface is exemplarily illustrated in combination with FIG. 2A, FIG. 4, FIG. 5, FIG. 6 and FIG. 7.

[0114] As another possible example, as shown in FIG. 4, the first interface includes a first display area and a second display area, the first display area is used to indicate the theoretical cruising capability, i.e., the theoretical cruising capability is 70%, and the second display area is used to indicate the lost cruising capability, i.e., the lost cruising capability is 20%. Optionally, the processing device can map the theoretical cruising capability to the first display area and map the lost cruising capability to the second display area.

[0115] Further, the first display area and the second display area include different graphics, for example, the first display area includes a first graphic and the second display area includes a second graphic. Optionally, the second graphic can cover the first graphic. The first graphic includes text, symbols, color blocks and / or icons, and the second graphic includes text, symbols, color blocks and / or icons, and the first graphic is different from the second graphic. For example, the first display area and the second display area are filled with different graphics, for example, the first display area is filled with the first graphic and the second display area is filled with the second graphic. As shown in FIG. 5, the first interface includes a first display area and a second display area, and FIG. 5 fills the first display area and the second display area with different color blocks as different graphics, the part of the first display area except the second area is filled with the first graphic, and the second display area is filled with the second graphic.

[0116] As another possible example, as shown in FIG. 6, the first interface includes a first display area, a second display area and a third display area, the third display area is used to indicate the rated capacity, i.e., 100%. The first display area is contained in the third display area, and the area or length ratio of the first display area in the third display area is used to indicate the relative relationship between the remaining capacity and the rated capacity, for example, the percentage of the remaining capacity to the rated capacity is 70%, and the area or length ratio of the first display area in the third display area is 70%, i.e., the theoretical cruising capability is 70%. The second display area is contained in the first display area, and the area or length ratio of the second display area in the third display area is used to indicate the relative relationship between the current unavailable capacity and the rated capacity, for example, the percentage of the current unavailable capacity to the rated capacity is 20%, and the area or length ratio of the first display area in the third display area is 20%, i.e., the theoretical cruising capability is 20%. The area refers to the size of the space occupied by the first display area when the space occupied by the first display area is a two-dimensional space.

[0117] The theoretical endurance capability is a percentage of the remaining capacity to the rated capacity, and the lost endurance capability is a percentage of the current unavailable capacity to the rated capacity. For example, the theoretical endurance capability is 467 km, and the lost endurance capability is 133 km. The first interface is similar to the above content, and will not be described again.

[0118] Further, the first display area and the second display area are filled with different patterns. For example, the first display area is filled with a first pattern, and the second display area is filled with a second pattern. The first pattern includes text, symbols, color blocks, and / or icons, and the second pattern includes text, symbols, color blocks, and / or icons. The first pattern is different from the second pattern. As shown in FIG. 7, the first interface includes the first display area, the second display area, and the third display area. In FIG. 7, the first display area and the second display area are filled with different patterns. The first display area is filled with a first pattern (dark diagonal lines), and the second display area is filled with a second pattern (dark vertical lines).

[0119] As a possible implementation, the second pattern can be related to the temperature data of the power battery. For example, at least one of the color of the second pattern, the flashing frequency of the second pattern, and the number of icons in the second pattern is related to at least one of the current temperature of the power battery, the temperature change trend, or the temperature change rate.

[0120] In a possible implementation, the processing device can obtain the temperature data of the power battery. The temperature data includes the current temperature of the power battery, and / or the temperature data is used to indicate at least one of the temperature change trend of the power battery and the temperature change rate of the power battery.

[0121] The temperature change trend of the power battery is decreasing or increasing. For example, the temperature change trend can be related to the battery thermal management system of the vehicle. When the battery thermal management system is started to heat the power battery, the temperature change trend of the power battery is increasing. When the battery thermal management system is started to cool the power battery, the temperature change trend of the power battery is decreasing. The battery thermal management system is used to cool the battery when the battery temperature is too high, and heat the battery when the battery temperature is too low, so that the battery can work in the best charging and discharging temperature range of the battery, to improve the battery performance. The temperature change rate is related to a time interval, for example, the time interval can be 1 hour, or 30 minutes, etc. For example, taking the time interval of 1 hour as an example, the temperature change rate can be 1 ℃ / h, 5 ℃ / h, etc.

[0122] Further, the processing device determines to fill the second display area with the second graphic according to the temperature data of the power battery, i.e. the processing device determines which graphic to fill the second display area with the second graphic according to the temperature data of the power battery.

[0123] Since at least one of the color of the second graphic, the flashing frequency of the second graphic and the number of icons in the second graphic is related to at least one of the current temperature of the power battery, the temperature change trend or the temperature change rate, including various possible correlation manners, the second graphic is related to the temperature data of the power battery is exemplarily described below in combination with FIG. 8, FIG. 9, FIG. 10, FIG. 11, FIG. 12 and FIG. 13. Of course, there can be more possible correlation manners in actual use, which are not exemplified one by one here. It should be noted that the first display area, the second display area and the third display area in FIG. 8, FIG. 9, FIG. 10, FIG. 11, FIG. 12 and FIG. 13 can refer to the description of the contents of the drawings in the foregoing, which will not be described here.

[0124] Example one, the color of the second graphic is related to the current temperature of the power battery. For example, the second graphic uses another color every time the temperature increases by 0.5℃, when the current temperature of the power battery is 5℃, the color of the second graphic is yellow, when the current temperature of the power battery is 20℃, the color of the second graphic is red, and when the current temperature of the power battery is -5℃, the color of the second graphic is blue.

[0125] Example two, the flashing frequency of the second graphic is related to the temperature change rate of the power battery. Optionally, the flashing frequency of the second graphic can increase as the temperature change rate of the power battery increases. For example, with a time interval of 1 hour, the flashing frequency of the second graphic when the temperature change rate is 1℃ / h is less than the flashing frequency of the second graphic when the temperature change rate is 5℃ / h.

[0126] In the example three, the second graphic is related to the temperature change trend of the power battery. For example, the color of the second graphic is related to the temperature change trend of the power battery, or the icon of the second graphic is related to the temperature change trend of the power battery. In the example, when the temperature change trend of the power battery is decreasing, the second display area is filled with a third graphic, and the second graphic is the third graphic. The third graphic can be a color block, for example, the color of the third graphic is blue or gray, or as shown in FIG. 8, the third graphic is a word freeze, or as shown in FIG. 9, the third graphic is a snowflake icon, and the third graphic is used to indicate that the power battery is currently in a cooling state. When the temperature change trend of the power battery is increasing, the second display area is filled with a fourth graphic, and the second graphic is the fourth graphic. The fourth graphic can be a color block, for example, the color of the fourth graphic can be orange, or as shown in FIG. 10, the fourth graphic is a word warm, or as shown in FIG. 11, the fourth graphic is a spark icon, and the fourth graphic is used to indicate that the power battery is currently in a heating state.

[0127] In the example four, the color of the second graphic is related to the current temperature of the power battery and the temperature change trend of the power battery. For example, the color of the second graphic is related to the current temperature of the power battery and the temperature change trend of the power battery, or the icon of the second graphic is related to the current temperature of the power battery and the temperature change trend of the power battery. In the example, when the temperature change trend of the power battery is no change in temperature, and the current temperature of the power battery is less than a temperature threshold, the second display area is filled with a third graphic, and the second graphic is the third graphic. The third graphic is described in the foregoing example three, and at this time, the third graphic is used to indicate that the power battery is currently in a low temperature state and the temperature is not changed. The temperature threshold is pre-set and can be related to the rated capacity of the power battery and the unusable SOC table of the power battery.

[0128] In the example five, the number of icons in the second graphic is related to the temperature change rate of the power battery and the temperature change trend of the power battery. Optionally, the shape of the icon in the second graphic is related to the temperature change trend of the power battery, and the number of icons in the second graphic can increase as the temperature change rate of the power battery increases. The temperature change rate is described above.

[0129] As shown in FIG. 9, when the temperature change trend of the power battery is decreasing, the third graphic is a snowflake icon, and at this time, the third graphic is the second graphic, i.e., the second graphic is a snowflake icon. When the temperature change rate is 1 ℃ / h, the number of icons of the second graphic is 1, i.e., 1 snowflake. As shown in FIG. 12, when the temperature change trend of the power battery is decreasing, the second graphic is a snowflake icon, and when the temperature change rate is 3 ℃ / h, the number of icons of the second graphic is 2, i.e., 2 snowflakes. That is, the number of icons of the second graphic when the temperature change rate is 1 ℃ / h is less than the number of icons of the second graphic when the temperature change rate is 3 ℃ / h, and the number of icons in the second graphic can increase with the increase of the temperature change rate of the power battery.

[0130] As shown in FIG. 11, when the temperature change trend of the power battery is increasing, the fourth graphic is a spark icon, and at this time, the fourth graphic is the second graphic, i.e., the second graphic is a spark icon. When the temperature change rate is 1 ℃ / h, the number of icons of the second graphic is 1, i.e., 1 spark. As shown in FIG. 13, when the temperature change trend of the power battery is increasing, the second graphic is a spark icon, and when the temperature change rate is 5 ℃ / h, the number of icons of the second graphic is 3, i.e., 3 sparks. That is, the number of icons of the second graphic when the temperature change rate is 1 ℃ / h is less than the number of icons of the second graphic when the temperature change rate is 5 ℃ / h, and the number of icons in the second graphic can increase with the increase of the temperature change rate of the power battery.

[0131] The above examples can improve the display effect of the first interface, so that the user can intuitively perceive the current loss of the power battery and the current working state of the power battery, for example, so that the user can intuitively perceive the change of the loss of the power battery with the temperature, which is beneficial to the user to better understand the current endurance of the power battery and improve the user experience.

[0132] As a possible implementation, the area size or length size of the third display area in the first interface is unchanged. The area size or length size of the first display area is related to the remaining capacity of the power battery. As an example, the processing device can update the area size or length size of the first display area according to the remaining capacity of the power battery. As an example, when the remaining capacity of the power battery decreases, the area size or length size of the first display area also decreases, and the processing device can update the proportion of the area size or length size of the first display area in the third display area according to the proportion of the remaining capacity of the power battery in the rated capacity. For example, when the rated capacity of the power battery is 100 kWh and the remaining capacity decreases from 70 kWh to 50 kWh, the proportion of the area size or length size of the first display area in the third display area decreases from 70% to 50%, i.e., the area size or length size of the first display area decreases.

[0133] The area size or length size of the second display area is related to the current unavailable capacity of the power battery. Illustratively, the processing device can update the area size or length size of the second display area according to the current unavailable capacity of the power battery. Illustratively, when the unavailable capacity of the power battery increases, the area size or length size of the second display area also increases, and the processing device can update the proportion of the area size or length size of the second display area in the third display area according to the proportion of the current unavailable capacity in the rated capacity of the power battery. For example, when the rated capacity of the power battery is 100 kWh and the current unavailable capacity increases from 20 kWh to 25 kWh, the proportion of the area size or length size of the second display area in the third display area increases from 20% to 25%, that is, the area size or length size of the second display area increases.

[0134] The following is a supplementary description of some of the above-described embodiments.

[0135] The first interface in the above-described figures or embodiments displays the value of the theoretical endurance and the value of the lost endurance. Alternatively, in actual use, the first interface can only display the value of the theoretical endurance or only display the value of the lost endurance, which is not limited here.

[0136] The first interface in the above-described figures or embodiments is illustratively described as a two-dimensional rectangle occupied by the first display area, the second display area, and the third display area. Of course, in actual use, the space occupied by the first display area, the second display area, and the third display area can also be a two-dimensional shape such as a ring, a square, a triangle, a trapezoid, a circle, etc., which will not be exemplified one by one here. As shown in FIG. 14, the space occupied by the first display area, the second display area, and the third display area is a two-dimensional ring, the space occupied by the third display area is the entire ring, i.e., 100%, the space occupied by the first display area is 70% of the entire ring, i.e., the theoretical endurance is 70%, and the space occupied by the second display area is 20% of the entire ring, i.e., the lost endurance is 20%. The foregoing embodiments can also be applied to the first interface shown in FIG. 14, which will not be exemplified one by one here.

[0137] The first interface is illustratively described as a two-dimensional space occupied by the first display area, the second display area, and the third display area. Of course, in actual use, the space occupied by the first display area, the second display area, and the third display area can also be a three-dimensional space or a higher-dimensional space, at which time the proportion of the space occupied by the first display area in the third display area is used to indicate the relative relationship between the remaining capacity and the rated capacity, and the proportion of the space occupied by the second display area in the third display area is used to indicate the relative relationship between the current unavailable capacity and the rated capacity, which will not be exemplified one by one here.

[0138] In the embodiment shown in FIG. 3, the theoretical cruising capability is related to the remaining capacity, and the remaining capacity is not related to the current unavailable capacity. Compared with the prior art, the remaining capacity in the embodiment of the present application does not change with the current working condition of the power battery, for example, does not change with the current temperature of the power battery. The embodiment of the present application displays the theoretical cruising capability through the first interface, which can improve the stability of the cruising capability of the power battery, for example, improve the stability of the power of the power battery or the stability of the change of the capacity of the power battery.

[0139] In addition, in the embodiment of the present application, the loss of cruising capability is related to the current unavailable capacity, and the current unavailable capacity is related to the current working condition of the power battery, for example, the current unavailable capacity changes with the current temperature of the power battery. The embodiment of the present application displays the loss of cruising capability through the first interface, so that the user can intuitively perceive the loss of cruising capability of the power battery, so that the user can more easily understand the current cruising capability of the power battery, and improve the user experience.

[0140] The above describes the method of the embodiment of the present application in detail. The following describes some devices for implementing the foregoing method. It should be understood that the devices provided in the embodiment of the present application are only a logical division of units, and can be all or partially integrated into a physical entity, or can be physically separated.

[0141] In addition, the units in the device can be implemented in the form of processor calling software, for example, the device includes a processor, the processor is connected with a memory, the memory stores instructions, and the processor calls the instructions stored in the memory to implement any one of the above methods or to implement the functions of each unit of the device, wherein the processor is a general processor, for example, a central processing unit (CPU) or a microprocessor, and the memory is a memory in the device or a memory outside the device.

[0142] Alternatively, the units in the apparatus can be implemented in the form of hardware circuitry, and part or all of the units can be implemented through design of hardware circuitry, which can be understood as one or more processors. For example, in one implementation, the hardware circuitry is an application-specific integrated circuit (ASIC) that is designed through logical relationship of elements in the circuit to implement part or all of the units. For another example, in another implementation, the hardware circuitry is a programmable logic device (PLD) that can be implemented through a field programmable gate array (FPGA). The FPGA can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured through a configuration file, so as to implement part or all of the units. All the units of the above apparatus can be implemented in the form of calling software by the processor, or in the form of hardware circuit, or part of them are implemented in the form of calling software by the processor, and the remaining part is implemented in the form of hardware circuit.

[0143] In the embodiments of the present application, the processor is a circuit with signal processing capability. In one implementation, the processor can be a circuit with instruction reading and running capability, such as a central processing unit (CPU) or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationship of hardware circuit, which is fixed or can be reconfigured. For example, the processor is an application-specific integrated circuit (ASIC) or a hardware circuit implemented by a programmable logic device (PLD), such as an FPGA. In the reconfigurable hardware circuit, the processor loads the configuration document to implement the hardware circuit configuration. The process can be understood as the process in which the processor loads instructions to implement part or all of the units. It can be seen that each unit in the apparatus can be one or more processors (or processing circuits) configured to implement the above method, such as a CPU, a GPU, a microprocessor, a DSP, an ASIC, an FPGA, or a combination of at least two of these processor forms.

[0144] In addition, all or some of the units in the above apparatus can be integrated or can be independent. In one implementation, these units are integrated to be in the form of an SOC (system on a chip). The SOC can include at least one processor for implementing the functions of the above methods or implementing the functions of the units of the apparatus. The at least one processor can be of different types, such as CPUs and FPGAs.
