Description

Technical Field

[0001] This application relates to the field of electric all-terrain vehicle technology, and more specifically, to an electric all-terrain vehicle and its charging indication method. Background Technology

[0002] With the development of technology, the electric all-terrain vehicle industry is constantly innovating and upgrading, and electric all-terrain vehicles have begun to appear on the market. Among the many functions of electric all-terrain vehicles, charging is undoubtedly the most frequently used. During the charging process, a charging indicator light is usually provided to indicate whether charging is successful, making it easy to determine whether charging has been completed.

[0003] In related technologies, once the charging port is successfully connected to the charging device and charging begins, the charging indicator light will illuminate and display a green light effect to indicate that the electric vehicle is successfully charging. However, the display of the charging indicator light in these technologies is rather simple, making it difficult for users to judge the charging progress. Summary of the Invention

[0004] In view of the above problems, this application provides an electric all-terrain vehicle and a charging indication method thereof, which makes it easy for users to judge the charging progress of the electric all-terrain vehicle.

[0005] In a first aspect, embodiments of this application provide an electric all-terrain vehicle, comprising a frame, a body panel, a running system, a power system, a power battery, a control system, and a lighting system; the body panel at least partially covers the frame; the running system is at least partially located below the frame; the power system is supported by the frame and connected to the running system; the power battery is supported by the frame and is used to supply power to the power system; the control system includes a battery management system electrically connected to the power battery; the lighting system includes a charging indicator light electrically connected to the battery management system; when the electric all-terrain vehicle is in a charging state, the battery management system controls the charging indicator light to emit a corresponding light signal according to the remaining charge value of the power battery; the light signal includes at least two of color information, brightness information, and breathing frequency information, wherein the color information includes at least two light colors; the brightness information includes at least light brightness; and the breathing frequency information is information on changes in light brightness, including at least two light breathing frequencies.

[0006] In some embodiments, the light signal includes color information. The total charge value of the power battery is divided into several non-overlapping charge ranges. When different remaining charge values ​​belong to the same charge range, the charging indicator light emits the same color. When different remaining charge values ​​belong to different charge ranges, the charging indicator light emits different colors.

[0007] In some embodiments, the light signal also includes light brightness, where the larger the remaining power value, the greater the corresponding light brightness when different remaining power values ​​belong to the same power range; and / or, the light signal also includes light breathing frequency, where the larger the remaining power value, the lower the corresponding light breathing frequency when different remaining power values ​​belong to the same power range.

[0008] In some embodiments, the light signal also includes light brightness, and when different remaining power values ​​belong to the same power range, the battery management system controls the charging indicator to emit the same light brightness; and / or, the light signal also includes light breathing frequency, and when different remaining power values ​​belong to the same power range, the battery management system controls the charging indicator to emit the same light breathing frequency.

[0009] In some embodiments, each power range has its own average power value, and the light brightness corresponding to the power range with a larger average power value is greater than the light brightness corresponding to the power range with a smaller average power value; and / or, the light breathing frequency corresponding to the power range with a larger average power value is lower than the light breathing frequency corresponding to the power range with a smaller average power value.

[0010] In some embodiments, each power range has its own maximum power value, minimum power value, and power value difference, where the power value difference is the difference between the corresponding maximum power value and the corresponding minimum power value; in two adjacent power ranges, the power value difference of the power range with the larger maximum power value is smaller than the power value difference of the power range with the smaller maximum power value.

[0011] In some embodiments, the light signal includes brightness information, which includes a first brightness and a second brightness. When the power battery is charging, if the increase in the remaining power value per unit time is less than or equal to a preset increase, the charging indicator light is lit at the first brightness; if the increase in the remaining power value per unit time is greater than the preset increase, the charging indicator light is lit at the second brightness.

[0012] In some embodiments, the brightness information also includes a third brightness. When the power battery is charging, and the charging temperature of the power battery obtained by the battery management system is greater than or equal to a preset temperature, the charging indicator light is lit at the third brightness.

[0013] In some embodiments, the charging indicator light includes a first indicator light and a second indicator light. The light signal emitted by the first indicator light includes only color information, and the light signal emitted by the second indicator light includes only brightness information and / or breathing frequency information.

This setting allows users to easily determine the charging progress of the electric all-terrain vehicle. Attached Figure Description

[0032] Please see Figure 1 and Figure 2 The electric all-terrain vehicle 100 includes at least one of the following: pure electric all-terrain vehicles, plug-in hybrid electric all-terrain vehicles, range-extended electric all-terrain vehicles, etc., which require charging, and is not limited here.

[0033] In some embodiments, taking a pure electric all-terrain vehicle as an example, the electric all-terrain vehicle 100 includes a frame 11, a body panel 12, a running system 13, a power system (not shown), a power battery 14, a control system 15, and a lighting system 16. The body panel 12 at least partially covers the frame 11. The running system 13 is at least partially connected to the frame 11. The power system is supported by the frame 11 and drives the running system 13, providing power to the running system 13. The power battery 14 is supported by the frame 11 and supplies power to the power system.

[0034] The walking system 13 includes a front wheel 131 and a rear wheel 132. The power system includes a drive motor, which is supported by the frame 11 and transmits power to the front wheel 131 and / or the rear wheel 132. The power battery 14 includes a power battery. The control system 15 includes a battery management system 151, which is electrically connected to the power battery 14. The lighting system 16 includes a charging indicator light 161, which reflects the charging progress.

[0035] For ease of description, this application defines the directions of front, rear, left, right, up, and down. The front-rear direction refers to the length of the frame 11 of the electric all-terrain vehicle 100, the left-right direction refers to the width of the frame 11, and the up-down direction refers to the height of the frame 11. In this embodiment, the directions of front, rear, left, right, up, and down are based on the state of the electric all-terrain vehicle 100 traveling on a level surface, not on a sloping surface.

[0036] In some embodiments, the charging indicator light 161 is a dedicated light fixture near the onboard charging port of the electric all-terrain vehicle 100 for indicating charging progress. In other embodiments, the charging indicator light 161 is an ambient light, daytime running light, or headlight of the electric all-terrain vehicle 100. Preferably, the charging indicator light 161 is a dedicated light fixture for indicating charging progress, and a low-cost RGB light can be selected.

[0037] The battery management system 151 can control the color, brightness, and breathing frequency of the charging indicator light 161. During charging, the battery management system 151 controls the charging indicator light 161 to emit corresponding light signals based on the remaining charge value of the power battery 14. The light signals include color information, which includes two to seven light colors. The light signals also include brightness information and / or breathing frequency information. The brightness information includes various light brightness levels, and the breathing frequency information is information about changes in light brightness, which includes various light breathing frequencies.

[0038] The total charge value of the power battery 14 is divided into several non-overlapping charge ranges. When different remaining charge values ​​belong to the same charge range, the battery management system 151 controls the charging indicator light 161 to emit the same light color. When different remaining charge values ​​belong to different charge ranges, the battery management system 151 controls the charging indicator light 161 to emit different light colors.

[0039] For example, the color information includes four light colors, and there are also four battery level ranges, each corresponding to a different color. Each battery level range represents 25% of the battery capacity. For instance, the first battery level range corresponds to a remaining battery value of 0 to 25%. When the current remaining battery value falls within the corresponding range, the battery management system 151 controls the charging indicator light 161 to emit the corresponding light color. This setup allows users to easily determine the vehicle's current charging progress simply by observing the light color.

[0040] In the first embodiment, when different remaining battery values ​​belong to the same battery range, the larger the remaining battery value, the brighter the corresponding light; when different remaining battery values ​​belong to different battery ranges, the larger the remaining battery value, the brighter the corresponding light is not necessarily. And / or, when different remaining battery values ​​belong to the same battery range, the larger the remaining battery value, the lower the corresponding light breathing frequency; when different remaining battery values ​​belong to different battery ranges, the larger the remaining battery value, the lower the corresponding light breathing frequency is not necessarily true.

[0041] Understandably, the light brightness and light breathing frequency corresponding to each power range are independent, meaning that the light brightness and light breathing frequency corresponding to the previous power range are not related to the light brightness and light breathing frequency corresponding to the next power range.

[0042] For example, during a certain period of the charging process, although the remaining power value continuously increases, it remains within the same power range. Therefore, during this period, the brightness of the light continuously increases, and / or the light breathing frequency continuously decreases.

[0043] If the remaining battery level continues to increase until it enters the next battery level range, the brightness of the light at this point can be greater, less, or unchanged compared to the previous battery level range. Once in the next battery level range, the brightness will continue to increase until the remaining battery level reaches the next range. Similarly, the light's breathing frequency follows the same pattern.

[0044] With this setup, users can roughly determine the charging progress by color, and can further determine the charging progress by light brightness or light breathing frequency.

[0045] In the second embodiment, when different remaining power values ​​belong to the same power range, the battery management system 151 controls the charging indicator light 161 to emit the same light brightness; when different remaining power values ​​belong to different power ranges, the battery management system 151 controls the charging indicator light 161 to emit different light brightness, and the larger the power value in the power range, the brighter the light.

[0046] And / or, when different remaining battery levels fall within the same battery range, the battery management system 151 controls the charging indicator light 161 to emit the same light breathing frequency. When different remaining battery levels fall within different battery ranges, the battery management system 151 controls the charging indicator light 161 to emit different light breathing frequencies, with the higher the battery level in the range, the lower the light breathing frequency.

[0047] Understandably, the light brightness and light breathing frequency corresponding to each power range are not independent. That is, the light brightness corresponding to the previous power range is greater than the light brightness corresponding to the next power range, and the light breathing frequency corresponding to the previous power range is lower than the light breathing frequency corresponding to the next power range.

[0048] For example, if during a certain period of the charging process, although the remaining power value continuously increases, the remaining power value always remains within the same power range, then during that period, the brightness of the light will not change, and / or the light breathing frequency will not change.

[0049] If the remaining power value continues to increase until it enters the next power range, the brightness of the light will be greater than that of the previous power range, and the light breathing frequency will be lower than that of the previous power range.

[0050] With this setup, users can roughly determine the charging progress by color, or by the brightness or breathing frequency of the light.

[0051] In some embodiments, each power range has its own maximum power value, minimum power value, average power value, and power value difference. The average power value is the average power value across the entire power range, and the power value difference is the difference between the corresponding maximum power value and the corresponding minimum power value. In one specific embodiment, among two adjacent power ranges, the power value difference between the range with the larger maximum power value is smaller than the power value difference between the range with the smaller maximum power value. In another specific embodiment, among two adjacent power ranges, the power value difference between the range with the larger average power value is smaller than the power value difference between the range with the smaller average power value.

[0052] This setting effectively shortens the range of the battery level range. In the early stages of charging with low remaining battery, users often pay little attention to the charging progress, but in the later stages with high remaining battery, users tend to pay more attention to the charging progress because they need to know roughly when charging will be complete. Therefore, by shortening the range of the battery level range, the changes in the light signal when the remaining battery is high become more noticeable.

[0053] In some embodiments, the light brightness corresponding to the power range with a larger average power value is greater than the light brightness corresponding to the power range with a smaller average power value. The light breathing frequency corresponding to the power range with a larger average power value is lower than the light breathing frequency corresponding to the power range with a smaller average power value.

[0054] This setup visually indicates the approximate remaining battery level through light brightness and breathing frequency, meaning users can disregard the light color. In other words, assuming users are not sensitive to light color, they can judge the charging progress simply by the light brightness and breathing frequency.

[0055] In some embodiments, the brightness information includes a first brightness, a second brightness, and a third brightness. When the power battery 14 is charging, if the increase in the remaining battery power value per unit time is less than or equal to a preset increase, the charging indicator light 161 illuminates at the first brightness. If the increase in the remaining battery power value per unit time is greater than the preset increase, the charging indicator light 161 illuminates at the second brightness. Here, the increase in the remaining battery power value per unit time can be understood as the charging rate, specifically, the increase in the remaining battery power value per second. In other embodiments, the increase in the remaining battery power value per unit time can also be equivalent to the charging power per unit time.

[0056] When the power battery 14 is charging, and the charging temperature of the power battery 14 obtained by the battery management system 151 is greater than or equal to a preset temperature, the charging indicator light 161 illuminates at the third brightness level. In this embodiment, the charging temperature can be the surface temperature of the power battery 14 or the internal temperature of the power battery 14. Specifically, the internal temperature of the power battery 14 can be measured using fiber Bragg grating (FBG) technology, thermistor-based measurement methods, equivalent temperature measurement methods, etc.

[0057] With this setting, users can observe the brightness to know the current charging rate and whether the battery temperature is too high.

[0058] In some embodiments, the charging indicator 161 includes a first indicator 1611 and a second indicator 1612. The light signal emitted by the first indicator 1611 includes only color information, and the light signal emitted by the second indicator 1612 includes only brightness information and / or breathing frequency information. Optionally, the light signal emitted by the second indicator 1612 includes only brightness information and breathing frequency information.

[0059] With this configuration, the first indicator light 1611 illuminates with a corresponding color based on the current remaining battery level, without changing brightness or dimming, and without any breathing-like variations. This helps users clearly observe the light color and make informed decisions. Since the second indicator light 1612 only emits light changes and breathing-like patterns, it can further supplement the charging progress information based on the first indicator light 1611.

[0060] Please see Figure 2 In some embodiments, the electric all-terrain vehicle 100 further includes a memory 17 and at least one communication bus 18. The battery management system 151 is used to implement a charging indication method for the electric all-terrain vehicle when executing a computer program stored in the memory 17, and at least one communication bus 18 is configured to enable communication between the memory 17, the power battery 14, the battery management system 151, and the charging indicator light 161, etc.

[0061] Figure 2The structure of the electric all-terrain vehicle shown does not constitute a limitation on the embodiments of this application. The electric all-terrain vehicle 100 may also include more or fewer other hardware or software, or different component arrangements than shown, which are not limited herein.

[0062] Please see Figure 3 This is a flowchart illustrating the charging indication method for an electric all-terrain vehicle provided in an embodiment of this application. The method is applied to an electric all-terrain vehicle, and this embodiment applies the method to... Figure 1 The method will be illustrated using the electric all-terrain vehicle 100 as an example. The method includes the following steps: S11, when the electric all-terrain vehicle 100 is in a charging state, obtain the remaining power value of the power battery 14.

[0063] In at least one embodiment of this application, the charging status indicates that the power battery of the electric all-terrain vehicle has established a connection with the charging device and is charging, at which time the remaining power value of the electric all-terrain vehicle is continuously increasing. In some embodiments, various parameters of the power battery in the electric all-terrain vehicle, such as voltage, current, and temperature, can be monitored by the vehicle body controller. By monitoring the above parameters in real time, the vehicle body controller can detect whether the electric all-terrain vehicle is in a charging state.

[0064] In some embodiments, if it is detected that the electric all-terrain vehicle is not in a charging state, it is not necessary to obtain the remaining power value of the electric all-terrain vehicle; if it is detected that the electric all-terrain vehicle is in a charging state, the remaining power value of the electric all-terrain vehicle is obtained, for example, the remaining power value of the energy storage battery in the electric all-terrain vehicle is obtained.

[0065] S12, determine the corresponding light signal based on the remaining power value, the light signal includes at least two of the following: light color, light brightness, and light breathing frequency.

[0066] In at least one embodiment of this application, the light color of the charging indicator light may include, but is not limited to, red, orange, yellow, green, cyan, blue, purple, and white. Specifically, taking four light colors as an example, the colors may be red, orange, yellow, and green. Light brightness can represent the luminous intensity of the charging indicator light corresponding to a certain light color; the greater the luminous intensity, the higher the light brightness; the smaller the luminous intensity, the lower the light brightness. The breathing frequency is the frequency at which the indicator light brightness changes; the faster the light brightness changes, the higher the breathing frequency; the slower the light brightness changes, the lower the breathing frequency.

[0067] S13 controls the charging indicator light 161 to emit a corresponding light signal.

[0068] In some embodiments, different remaining battery levels correspond to different light brightness and breathing frequencies. For example, determining the corresponding light brightness and breathing frequency based on the remaining battery level includes: The total capacity of the power battery is divided into several non-overlapping capacity ranges; The target power range corresponding to the remaining power value is determined. In this embodiment, the light signal also includes brightness information and breathing frequency information.

[0069] The remaining battery level can be divided into multiple ranges based on its value. The remaining battery level range is 0-100%, and this range can be further divided into multiple ranges. The number of ranges can be set according to actual needs. For example, four ranges can be defined: 0-Q1%, Q1%-Q2%, Q2%-Q3%, and Q3%-100%. Q1 can range from 25 to 50. Optionally, Q1 is 40. In other embodiments, Q1 can be any value from 25, 30, 34, 45, 48, to 50. In other embodiments, Q1 can also be a value outside the range of 25-50, such as 20, 52, or other values. Q2 can range from 55 to 90. Optionally, Q2 is 70. In other embodiments, Q2 can also be any value from 55, 60, 71, 80, 85, to 90. In some embodiments, Q2 can also be a value outside the range of 55-90, such as Q2 being 92 or other values. The value range of Q3 is 95-99. Optionally, Q3 is 98. In some embodiments, Q3 can also be any value among 95, 96, 97, and 99. In some embodiments, Q3 can also be a value outside the range of 95-99, such as Q3 being 93 or 94 or other values. For example, the power range is divided into three segments: 0-Q1%, Q1%-Q2%, and Q2%-100%, where Q1 is a value between 25 and 50. Optionally, Q1 is 40. In some embodiments, Q1 can also be any value among 25, 30, 34, 45, 48, and 50. In some embodiments, Q1 can also be a value outside the range of 25-50, such as Q1 being 20 or 52 or other values. The value range of Q2 is 60-99. Alternatively, Q2 is 85. In other embodiments, Q2 can also be any value among 60, 70, 80, 95, 97, and 99. In other embodiments, Q2 can also take values ​​outside the range of 60 to 99, such as Q2 being 55 or other values.

[0070] In some embodiments, a first correspondence between power range and light brightness, and a second correspondence between power range and breathing frequency are preset. By querying the first correspondence, the light brightness corresponding to the target power range can be determined, and by querying the second correspondence, the breathing frequency corresponding to the target power range can be determined.

[0071] In at least one embodiment of this application, a light signal for a charging indicator light of an electric all-terrain vehicle is generated and sent to the driving circuit of the charging indicator light. Upon receiving the light signal, the driving circuit controls the charging indicator light to illuminate according to the instructions in the light signal, specifying the light color, brightness, and breathing frequency. As the remaining battery level changes, the light signal needs to be updated in real time based on the remaining battery level.

[0072] In the electric all-terrain vehicle charging indication method provided in this application embodiment, if the electric all-terrain vehicle is detected to be charging, the charging indicator light is controlled to illuminate according to the remaining power value of the electric all-terrain vehicle, with a brightness and breathing frequency corresponding to the remaining power value. This method enables the charging indicator light to reflect the charging progress of the electric all-terrain vehicle in real time, allowing the user to clearly know when charging is complete, thereby more accurately controlling the charging time, avoiding overcharging or ineffective charging, and reducing the waste of electrical resources.

[0073] It's worth noting that when different remaining battery levels fall within the same range, the battery management system controls the charging indicator light to emit the same color. Conversely, when different remaining battery levels fall within different ranges, the battery management system controls the charging indicator light to emit different colors.

[0074] For example, the color information includes four light colors, and there are also four battery level ranges, each corresponding to a different color. Each range represents 25% of the battery capacity; for instance, the first range corresponds to a remaining battery level of 0 to 25%. When the current remaining battery level falls within the corresponding range, the battery management system controls the charging indicator light to emit the corresponding color. This design allows users to easily determine the vehicle's current charging progress simply by observing the light color.

[0075] When different remaining battery values ​​belong to the same battery range, the larger the remaining battery value, the brighter the corresponding light. However, when different remaining battery values ​​belong to different battery ranges, a larger remaining battery value does not necessarily mean a brighter corresponding light. And / or, when different remaining battery values ​​belong to the same battery range, the larger the remaining battery value, the lower the corresponding light breathing frequency; when different remaining battery values ​​belong to different battery ranges, the larger the remaining battery value, the lower the corresponding light breathing frequency is not necessarily true.

[0076] With this setup, users can roughly determine the charging progress by color, and can further determine the charging progress by light brightness or light breathing frequency.

[0077] When different remaining battery levels fall within the same battery range, the battery management system controls the charging indicator light to emit the same brightness. When different remaining battery levels fall within different battery ranges, the battery management system controls the charging indicator light to emit different brightness levels, with the brightness increasing for battery ranges with larger remaining battery levels.

[0078] And / or, when different remaining battery levels fall within the same battery range, the battery management system controls the charging indicator light to emit the same breathing frequency. When different remaining battery levels fall within different battery ranges, the battery management system controls the charging indicator light to emit different breathing frequencies, with the breathing frequency decreasing for larger battery levels.

[0079] With this setup, users can roughly determine the charging progress by color, or by the brightness or breathing frequency of the light.

[0080] In at least one embodiment of this application, before determining the target power range corresponding to the remaining power value, the number of power ranges can be determined in combination with the user's charging preferences. Figure 4 This is a flowchart illustrating the power range setting method provided in the first embodiment of this application, which is applied to electric all-terrain vehicles. Figure 4 As shown, it includes the following steps: S21, Determine the input information of the target user.

[0081] This input information can include the user's charging preferences.

[0082] In at least one embodiment of this application, charging preference information is used to characterize the user's attention to the charging progress. For example, charging preference information can be determined by monitoring the number of times the target user appears during the charging of the electric all-terrain vehicle. For example, monitoring the number of times the target user opens the door during the charging of the electric all-terrain vehicle, or monitoring the number of times the target user stands in front of the charging indicator light of the electric all-terrain vehicle during the charging of the electric all-terrain vehicle by means of facial recognition.

[0083] In some embodiments, if the number of times a target user appears during the charging period of the electric all-terrain vehicle is greater than or equal to a preset threshold, it is determined that the user has a high level of concern about the charging progress; if the number of times a target user appears during the charging period of the electric all-terrain vehicle is less than the preset threshold, it is determined that the user has a low level of concern about the charging progress. The target user can represent the owner of the electric all-terrain vehicle. The owner's facial information can be collected in advance, and then facial recognition can be used to monitor the number of times the owner stands in front of the charging indicator light on the electric all-terrain vehicle during charging. The preset threshold can be set according to actual needs; for example, a preset threshold of 2 times is not limited here.

[0084] S22 determines the number of power ranges based on charging preference information.

[0085] In at least one embodiment of this application, if the charging preference information indicates that the user pays little attention to the charging progress, a small number of power ranges can be set. If the charging preference information indicates that the user pays more attention to the charging progress, multiple power ranges can be set, allowing the user to more accurately determine the remaining power value of the electric all-terrain vehicle by checking the charging indicator light.

[0086] S23 sets the corresponding battery range based on the number of battery ranges. That is, the range of battery values ​​corresponding to each battery range.

[0087] In at least one embodiment of this application, a corresponding power range is set based on the number of ranges. For example, when there are four ranges, the power ranges include 0~Q1%, Q1%~Q2%, Q2%~Q3%, and Q3%~100%, respectively. When there are three ranges, the power ranges include 0~Q1%, Q1%~Q2%, and Q2%~100%, respectively.

[0088] In the electric all-terrain vehicle charging indication method provided in this application embodiment, the number of intervals is determined according to the charging preference information of the target user, and then the corresponding power range is set based on the number of intervals. The above method can make the setting of power range meet the user's needs and improve the accuracy of power range setting.

[0089] In another embodiment, the range of battery values ​​corresponding to each battery level interval is determined according to preset conditions. The preset conditions can be data pre-written into the vehicle body controller. Specifically, the preset conditions include: each battery level interval has its own maximum battery value, minimum battery value, and battery value difference, where the battery value difference is the difference between the corresponding maximum battery value and the corresponding minimum battery value; in two adjacent battery level intervals, the battery value difference between the interval with the larger battery value is smaller than the battery value difference between the interval with the smaller battery value.

[0090] In at least one embodiment of this application, the difference in battery power values ​​between different battery power ranges may be the same or different. This application provides an example where the difference in battery power values ​​between different battery power ranges is different. Figure 5 This is a flowchart illustrating the power range setting method provided in the second embodiment of this application, which is applied to electric all-terrain vehicles. Figure 5 As shown, it includes the following steps: S31 sorts multiple power ranges based on power information.

[0091] In at least one embodiment of this application, multiple power ranges are sorted according to the power information from low to high. Continuing with the above embodiments, when the power ranges include 0~Q1%, Q1%~Q2%, Q2%~Q3%, and Q3%~100%, 0~Q1% is sorted first, and Q3%~100% is sorted last.

[0092] S32, determine the first power difference of the first power range that is ranked first, and the second power difference of the second power range that is ranked second, wherein the first power difference is greater than or equal to the second power difference.

[0093] In at least one embodiment of this application, the remaining battery power value of the first battery power interval ranked first is smaller, and the remaining battery power value of the second battery power interval ranked second is greater than the remaining battery power value within the first battery power interval. A first battery power difference value for the first battery power interval ranked first, and a second battery power difference value for the second battery power interval ranked second, are calculated. Continuing with the above embodiment, the battery power difference value for the battery power interval 0~Q1% is calculated to obtain a battery power difference value of Q1. The battery power difference value for the battery power interval Q1%~Q2% is calculated to obtain a battery power difference value of Q2-Q1. The battery power difference value for the battery power interval Q2%~Q3% is calculated to obtain a battery power difference value of Q3-Q2. The battery power difference value for the battery power interval Q3%~100% is calculated to obtain a battery power difference value of 100-Q3.

[0094] In some embodiments, it is considered that users pay relatively less attention to the charging progress in the early stages of charging, while their attention to the charging progress is relatively higher in the middle and later stages. This application sets the second battery difference value, which is ranked later, to be greater than or equal to the first battery difference value, which is ranked earlier. For example, the battery difference value 100-Q3 is set to be the minimum, and the battery difference value Q1 is set to be the maximum.

[0095] In the electric all-terrain vehicle charging indication method provided in this application embodiment, by setting different power value differences for different power ranges, and setting a larger power value difference for power ranges with larger remaining power values, the above method enables users to more accurately determine the power range of the electric all-terrain vehicle in the middle and later stages of charging.

[0096] In at least one embodiment of this application, the target power range includes at least one light brightness. When the target power range includes one light brightness, it indicates that the light brightness remains constant within the target power range. When the target power range includes multiple light brightnesses, it indicates that the light brightness varies within the target power range. Figure 6 This is a schematic flowchart of a headlight brightness adjustment method provided in an embodiment of this application, which is applied to an electric all-terrain vehicle. Figure 6 As shown, it includes the following steps: S41, the light brightness corresponding to the power range includes the first light brightness and the second light brightness.

[0097] In at least one embodiment of this application, the first light brightness represents the minimum brightness corresponding to the target power range, and the second light brightness represents the maximum brightness corresponding to the target power range. Continuing with the above embodiments, when the power battery power is between 0% and Q1%, the luminous intensity of the charging indicator light at any time is L1cd. The minimum L1 value corresponding to 0% to Q1% is recorded as the first light brightness, and the maximum L1 value corresponding to 0% to Q1% is recorded as the second light brightness; when the power battery power is between Q1% and Q2%, the luminous intensity of the charging indicator light at any time is L2cd. The minimum L2 value corresponding to Q1% to Q2% is recorded as the first light brightness, and the maximum L2 value corresponding to Q1% to Q2% is recorded as the second light brightness. When the battery charge is between Q2% and Q3%, the luminous intensity of the charging indicator light at any given time is L3cd. The minimum L3 value corresponding to Q2%~Q3% is recorded as the first light brightness, and the maximum L3 value corresponding to Q2%~Q3% is recorded as the second light brightness. When the battery charge is between Q3% and 100%, the luminous intensity of the charging indicator light at any given time is L4cd. The minimum L4 value corresponding to Q3%~100% is recorded as the first light brightness, and the maximum L4 value corresponding to Q3%~100% is recorded as the second light brightness. Here, "cd" is the symbol for the candela, the international unit of luminous intensity.

[0098] S42, obtain the first light brightness and the second light brightness corresponding to the target power range; control the charging indicator light to change brightness between the first light brightness and the second light brightness corresponding to the target power range.

[0099] In at least one embodiment of this application, the preset brightness illumination rules can be set according to actual needs. For example, the preset brightness illumination rules include the following cases: For example, if there are four battery ranges, please refer to [link / reference]. Figure 7 , Figure 7This is a schematic diagram of light brightness variation provided in the first embodiment of this application. The maximum values ​​of L1, L2, L3, and L4 increase sequentially. For example, the maximum value of L1 is 10, the maximum value of L2 is 20, the maximum value of L3 is 30, and the maximum value of L4 is 38. In some other embodiments, the maximum values ​​of L1, L2, L3, and L4 may also decrease sequentially.

[0100] L1 follows a cyclical pattern of increasing and then decreasing multiple times; L2 follows the same pattern; L3 follows the same pattern; and L4 follows the same pattern. Furthermore, the minimum values ​​of L1, L2, L3, and L4 increase sequentially. For example, the minimum value of L1 is 2, the minimum value of L2 is 4, the minimum value of L3 is 6, and the minimum value of L4 is 20. In other embodiments, the minimum values ​​of L1, L2, L3, and L4 may decrease sequentially. In other embodiments, the minimum values ​​of L1, L2, L3, and L4 may also be all or partially equal. For example, the minimum values ​​of L1, L2, L3, and L4 may all be equal to 0, 2, or other values.

[0101] Please see Figure 8 , Figure 8 This is a schematic diagram of light brightness variation provided in the second embodiment of this application. The minimum value of L1, the maximum value of L1, the minimum value of L2, the maximum value of L2, the minimum value of L3, the maximum value of L3, the minimum value of L4, and the maximum value of L4 increase sequentially. In some other embodiments, the maximum value of L1, the minimum value of L1, the maximum value of L2, the minimum value of L2, the maximum value of L3, the minimum value of L3, the maximum value of L4, and the minimum value of L4 may decrease sequentially.

[0102] Please see Figure 9 , Figure 9 This is a schematic diagram of the light brightness change provided in the third embodiment of this application. L1 follows a single-cycle change pattern from small to large, L2 follows a single-cycle change pattern from small to large, L3 follows a single-cycle change pattern from small to large, and L4 follows a single-cycle change pattern from small to large. It can be understood that in each charging stage, the luminous intensity of the charging indicator light 161 gradually increases with the increase of the power battery 14's charge, and the luminous intensity of the charging indicator light 161 reaches its maximum when the power battery 14 is fully charged.

[0103] For an example, if there are three battery ranges, please refer to [link / reference]. Figure 10 , Figure 10This is a schematic diagram of light brightness variation provided in the fourth embodiment of this application. The maximum values ​​of L1, L2, and L3 increase sequentially. For example, the maximum value of L1 is 10, the maximum value of L2 is 20, and the maximum value of L3 is 30. In other embodiments, the maximum values ​​of L1, L2, and L3 may also decrease sequentially. L1 follows a cyclical pattern of increasing and decreasing multiple times; L2 follows a cyclical pattern of increasing and decreasing multiple times; L3 follows a cyclical pattern of increasing and decreasing multiple times.

[0104] In some embodiments, when adjusting the brightness of the first light and the second light according to a preset brightness lighting rule, the brightness of the first light and the second light are also adjusted in conjunction with the breathing frequency. The breathing frequency of L1 is F1, the breathing frequency of L2 is F2, the breathing frequency of L3 is F3, and the breathing frequency of L4 is F4, with F1, F2, F3, and F4 decreasing sequentially; for example, F1 is 2.5 times per second, F2 is 1.5 times per second, F3 is 1 time per second, and F4 is 0.5 times per second. In other embodiments, F1, F2, F3, and F4 may increase sequentially. In other embodiments, two, three, or all of F1, F2, F3, and F4 may be equal.

[0105] In the electric all-terrain vehicle charging indication method provided in this application embodiment, the first light brightness and the second light brightness are lit according to different brightness lighting rules, so that the charging indicator can reflect the charging progress of the electric all-terrain vehicle in real time, so that the user can clearly know when the charging is completed, thereby more accurately controlling the charging time, avoiding overcharging or ineffective charging, and thus reducing the waste of power resources.

[0106] In at least one embodiment of this application, the charging indicator light includes multiple indicator lights; optionally, the illumination ratio of the multiple indicator lights is determined based on the remaining power level of the power battery. The remaining power level of the battery is positively correlated with the illumination ratio of the multiple indicator lights. Figure 11 This is a flowchart illustrating the indicator light display method provided in an embodiment of this application. The indicator light display method is applied to an electric all-terrain vehicle. Figure 11 As shown, it includes the following steps: S51 determines the number of charging indicator lights to be illuminated based on the remaining battery level. There are multiple charging indicator lights.

[0107] In at least one embodiment of this application, the charging indicator light consists of multiple small LEDs or other light-emitting elements surrounding the charging port. The multiple small LEDs can form a light strip, and the proportion of the remaining battery level can be reflected by the proportion of the indicator lights lit in the light strip. In some embodiments, the lighting ratio of the multiple indicator lights is determined based on the proportion of the remaining battery level to the total battery level.

[0108] S52 indicates that the lit charging indicator light illuminates according to the corresponding light brightness and breathing frequency.

[0109] In the electric all-terrain vehicle charging indication method provided in this application embodiment, the illumination ratio of multiple indicator lights is determined according to the remaining power value. Multiple indicator lights are then illuminated according to the illumination ratio, and the illuminated indicator lights are controlled to illuminate with a brightness and breathing frequency corresponding to the remaining power value. This method allows users to quickly understand the remaining power value of the power battery by observing the illumination of the indicator lights; this display method is relatively intuitive and easy to understand.

[0110] In at least one embodiment of this application, during the charging process of the electric all-terrain vehicle, it is possible to monitor whether there is any abnormality in the charging status of the electric all-terrain vehicle. Figure 12 This is a flowchart illustrating the charging state determination method provided in an embodiment of this application. The charging state determination method is applied to electric all-terrain vehicles. Figure 12 As shown, it includes the following steps: S61: Monitor the charging status of the electric all-terrain vehicle for any abnormalities. If an abnormality is detected, proceed to S62; otherwise, continue with S61.

[0111] In at least one embodiment of this application, the presence of an abnormal charging state is used to characterize a fault that occurs in the power battery during the charging process. For example, when the power battery overheats, experiences unstable current, or exhibits abnormal voltage during the charging process, it is determined that there is an abnormal charging state.

[0112] S62, adjust the color of the charging indicator light to the abnormal light color.

[0113] In at least one embodiment of this application, if an abnormality occurs in the charging status, the color of the charging indicator light is adjusted to the abnormal light color. The abnormal light color can be set according to actual needs; for example, the abnormal light color can be red.

[0114] In the electric all-terrain vehicle charging indication method provided in this application embodiment, the charging status of the electric all-terrain vehicle is monitored, and when there is an abnormality in the charging status, the color of the charging indicator light is adjusted to the abnormal light color, so that the user can intuitively see the charging status of the electric all-terrain vehicle.

[0115] In at least one embodiment of this application, if the electric all-terrain vehicle meets the target light-off conditions, the charging indicator light is turned off. The target light-off conditions include at least one of the following: the electric all-terrain vehicle's power battery is in a closed state; the charging port cover of the electric all-terrain vehicle is in a closed state; the electric all-terrain vehicle's gear is adjusted to a target gear; and the illumination duration of the charging indicator light is greater than or equal to a preset duration. Specifically, when the electric all-terrain vehicle's power battery is in a closed state and / or the charging port cover is in a closed state, it indicates that the electric all-terrain vehicle is not charging, and the charging indicator light can be turned off. The target gear may include forward and reverse gears. When the electric all-terrain vehicle's gear is adjusted to the target gear, it indicates that the electric all-terrain vehicle is not charging, and the charging indicator light can be turned off. The preset duration can be set according to actual needs; for example, the preset duration may include 50 minutes. When the illumination duration of the charging indicator light is greater than or equal to the preset duration, it indicates that the electric all-terrain vehicle is not charging, and the charging indicator light can be turned off.

[0116] Additionally, if there is an abnormality in the charging status and the electric all-terrain vehicle does not meet the target conditions for turning off the lights, the color of the charging indicator light will change; if there is an abnormality in the charging status and the electric all-terrain vehicle meets the target conditions for turning off the lights, the backup warning device will be controlled to issue a warning signal. The backup warning device can be a light fixture, an audible warning device such as a buzzer, or a signal transmission module integrated into the vehicle controller. The warning signal is information transmitted wirelessly to the user's terminal.

[0117] In the electric all-terrain vehicle charging indication method provided in this application embodiment, the charging indicator light is turned off in a timely manner when the electric all-terrain vehicle meets the target light-off condition, thus avoiding damage to the power battery.
