[0030] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] It should be noted that in the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being more preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0032] In order to facilitate a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with basically the same functions and effects. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order.

[0033] The rapid development of the new energy vehicle industry has led to a significant expansion in the user base, and vehicle safety has subsequently become a focus of industry attention. Currently, mainstream safety research and practice focus on core components such as power batteries and drive motors. However, the potential risks of the charging port, a key physical interface for power transmission, have not received sufficient attention. This port is subject to repeated plugging and unplugging operations during the vehicle's lifecycle, and its electrical contact surface will inevitably experience progressive wear, performance degradation, and even rust. This continued deterioration in contact conditions will lead to increased contact resistance, which in turn will cause abnormal temperature rise. If this problem is not effectively monitored and prevented, it may eventually lead to electrical fire hazards, posing a threat to the safety of vehicles and users.

[0034] Against this background technology, an embodiment of the present application provides a charging port life warning method, device, equipment and storage medium, which are applied to vehicles. The method includes: obtaining attribute information of the charging port; the attribute information includes the actual number of plug-ins and unplugs and / or the temperature of the charging port; according to the attribute information, determining the different life stages of the charging port; and outputting different prompt information at different life stages. It can be seen that when the embodiment of the present application provides a warning for the life of the charging port, by obtaining the attribute information of the actual number of plug-ins or the temperature of the charging port, or obtaining both attribute information at the same time, the different life stages of the charging port are determined, and different prompt information is obtained. In this way, safety issues caused by the number of plug-ins or the temperature of the charging port can be effectively prevented, avoiding threats to the safety of the vehicle and users.

[0035] Figure 1 This is a schematic diagram of an application scenario of a charging port life warning method provided in an embodiment of the present application. Figure 1 As shown, a vehicle controller 101 , a charging port 102 , and a temperature sensor 103 .

[0036] Among them, the vehicle controller 101 is responsible for monitoring sensor data, processing information, making decisions and executing commands to accurately control the various subsystems of the vehicle to ensure its safe, efficient and comfortable operation.

[0037] The charging port 102 is a physical interface on the device for connecting a charging cable to replenish power for the battery inside the device.

[0038] The temperature sensor 103 is an electronic device that converts temperature changes into a measurable electrical signal. It can be used to monitor the temperature of key parts in real time and transmit this data to the controller. Each charging port 102 has a built-in temperature sensor 103 to record the temperature of the charging port. The temperature controller 103 is used to obtain the maximum temperature of the charging port during charging.

[0039] It can be understood that the embodiment of the present application provides a charging port life warning method, which obtains the number of times the vehicle has been charged through the vehicle controller 101, and the maximum temperature of the charging port 102 during the charging process through the temperature controller 103. According to the actual number of plug-in and unplugging times and / or the attribute information of the temperature of the charging port 102, the different life stages of the charging port are determined, and different prompt information is obtained respectively, so as to effectively prevent safety problems caused by the number of plug-in and unplugging times or the temperature of the charging port 102, and avoid posing a threat to the safety of the vehicle and users.

[0040] Figure 2 This is a flow chart of a charging port life warning method provided in an embodiment of the present application. This method can be applied to Figure 1 In the scenario shown, the following steps S201-S203 are specifically included:

[0041] S201. Obtain attribute information of the charging port, where the attribute information includes actual plug-in and unplug times and / or charging port temperature.

[0042] Attribute information refers to the inherent, intrinsic, and basic characteristics, properties, or features of an object. The number of times a charging port is plugged in and out and the temperature of the charging port are attribute information of the charging port involved in the embodiments of this application.

[0043] Optionally, the actual number of plug-in and unplugging times and / or the charging port temperature may be expressed as: actual number of plug-in and unplugging times, actual charging port temperature, actual number of plug-in and unplugging times, and charging port temperature.

[0044] In some embodiments, obtaining the actual number of plugging and unplugging times of the charging port includes: obtaining the number of times the vehicle has been charged from a controller of the vehicle as the actual number of plugging and unplugging times.

[0045] It should be understood that each time the vehicle is charged, the charging port is plugged in and out of the charging gun once. Therefore, the number of times the vehicle has been charged can be regarded as the actual number of times the charging port has been plugged in and out.

[0046] For example, when the vehicle has not been charged, if the number of times it has been charged is 0, the actual number of plugging and unplugging is 0; when the vehicle has been used for a period of time, if the number of times it has been charged is 30, the actual number of plugging and unplugging is 30.

[0047] In some embodiments, a temperature sensor is provided at the charging port; obtaining the charging port temperature of the charging port includes: during each charging process, recording the maximum temperature of the charging port during the current charging process through the temperature sensor as the charging port temperature.

[0048] For example, in a public fast-charging area, the vehicle charging process takes half an hour. The temperature sensor monitors the charging port temperature in the range of 15-25°C in real time during the charging process, and records 25°C as the charging port temperature during the current charging process.

[0049] It is understood that in the embodiments of the present application, there are three options for obtaining the attribute information of the charging port: Option 1 simultaneously obtains the actual plug-in and unplug counts and the actual charging temperature; Option 2 obtains the actual plug-in and unplug counts; and Option 3 obtains the actual charging temperature. Among them, the number of charges obtained by the vehicle controller is used as the actual plug-in and unplug count, and the maximum temperature of the charging port during the current charging process recorded by the temperature sensor is used as the charging port temperature. Multi-dimensional monitoring of the charging port information effectively provides substantial data support for charging port warnings.

[0050] S202: Determine different life stages of the charging port based on the attribute information.

[0051] Among them, the life cycle stage refers to the division of the entire process that a system, product or project goes through from conception to final abandonment.

[0052] Optionally, there are three schemes for obtaining attribute information in step S201. Scheme 1 simultaneously obtains the actual number of plug-ins and the actual charging temperature, scheme 2 obtains the actual number of plug-ins, and scheme 3 obtains the actual charging temperature, all of which are applicable to the following life stages.

[0053] In some embodiments, different life stages include at least: a first life stage, a second life stage, and a third life stage; wherein the first life stage is better than the second life stage, and the second life stage is better than the third life stage.

[0054] It is understandable that the division into different life stages is at least the current three stages, and can also be divided into more stages. The embodiments of the present application do not make specific limitations on this.

[0055] For example, life stages can be added to predict risks and provide reminders multiple charging cycles in advance.

[0056] Optionally, the first life stage is at least due to the current charging port not being correctly inserted or not being clean, such as the charging cable not being fully inserted or twisted, or the charging port being dusty or liquid-filled. The first life stage is mainly due to the charging port being affected by external factors.

[0057] Optionally, the second life stage is divided at least because the charging port is damaged or there are certain safety hazards, and the charging port needs to be replaced.

[0058] Optionally, the third life stage is divided because the current charging port is severely damaged and its life is exhausted, so the charging port needs to be replaced immediately.

[0059] Among them, being in the second life stage or the third life stage is mainly due to the condition of the charging port itself.

[0060] The first lifespan stage is optional, based more on external factors and allowing for timely intervention. The second lifespan stage indicates a potential safety hazard and warrants replacement of the charging port. The third lifespan stage indicates the current charging port has reached end-of-life status and must be replaced immediately. The first lifespan stage is superior to the second lifespan stage, allowing for early intervention to extend the lifespan of the charging port. The second lifespan stage is superior to the third lifespan stage, which can also be addressed promptly. However, the third lifespan stage indicates a serious safety hazard and requires a timely warning to the user.

[0061] It is understandable that by dividing the charging port into different life stages, defects can be discovered early, prevented in advance, and the life of the charging port can be effectively extended.

[0062] S203: Output different prompt information at different life stages.

[0063] Among them, the prompt information is used to provide corresponding early warning information for different life stages to facilitate better early intervention.

[0064] In some embodiments, different life stages include at least: a first life stage, a second life stage, and a third life stage; wherein, the first life stage is better than the second life stage, and the second life stage is better than the third life stage; in the first life stage, prompt information is used to remind the user to standardize the plugging and unplugging posture, and to clean the charging port; in the second life stage, prompt information is used to remind the user to replace the charging port in time; in the third life stage, prompt information is used to remind the user that the life of the charging port is exhausted and the charging port needs to be replaced.

[0065] For example, the standardized plugging and unplugging posture can remind users to align the direction of the interface, keep the data cable charging head completely parallel to the charging port, push in or pull out gently, and avoid tilting or using force.

[0066] It is understandable that corresponding prompt information will be output for different life stages in step S202. Because the charging port is not inserted correctly or the charging port is not clean, the prompt information in the first life stage is used to remind the user to standardize the plugging and unplugging posture and clean the charging port. Because the charging port is damaged and there are certain safety hazards, the charging port needs to be replaced. The prompt information in the second life stage is used to remind the user to replace the charging port in time. Because the current charging port has exhausted its life, the charging port needs to be replaced immediately. The prompt information in the third life stage is used to remind the user that the charging port has exhausted its life and needs to be replaced.

[0067] In some embodiments, the charging port life warning method further includes: sending a prompt message to a cloud platform so that the cloud platform assists in providing a user with a charging port life warning.

[0068] The cloud platform can be either a car manufacturer's or a national regulatory platform. For example, prompts are sent to the owner through the vehicle's computer system, including but not limited to screen display, voice announcement, and application (APP) push notifications. Furthermore, these prompts are uploaded to the cloud platform, which can then take follow-up actions based on the prompts, such as contacting the user via phone or text message to prompt them to inspect or replace the charging port.

[0069] It is understandable that the prompt information obtained through the charging port life warning method is sent to the cloud platform. On the one hand, the cloud platform can help remind users to handle the charging port life warning, so that users can pay attention to the charging port life information in a timely manner, thereby extending the life of the charging port. On the other hand, the cloud platform can collect a large amount of data to provide data support for subsequent solution optimization.

[0070] It is understood that when providing a warning about the life of the charging port, the embodiments of the present application obtain charging port attribute information such as the actual number of plug-in and unplug cycles or the charging port temperature, or both, to determine the different life stages of the charging port and obtain different prompt information. This approach can effectively prevent safety issues caused by the number of plug-in and unplug cycles or the temperature of the charging port, avoiding threats to vehicle and user safety.

[0071] The following describes in detail the charging life warning method provided in the embodiment of the present application based on the three schemes for obtaining the attribute information in step S201, including scheme 1 for simultaneously obtaining the actual number of plug-in and plug-out times and the actual charging temperature, scheme 2 for obtaining the actual number of plug-in and plug-out times, and scheme 3 for obtaining the actual charging temperature.

[0072] Option 1

[0073] In some embodiments, the attribute information includes the actual number of plug-in and unplugging times and the temperature of the charging port; based on the attribute information, the different life stages of the charging port are determined, including: determining a temperature change curve based on the attribute information; the temperature change curve is used to indicate the trend of the charging port temperature increasing with the actual number of plug-in and unplugging times during actual use; obtaining a standard curve; the standard curve is used to indicate the trend of the charging port temperature increasing with the number of plug-in and unplugging times under ideal conditions; if the difference between the first slope and the second slope is greater than the first slope threshold, it is determined that the charging port is in the first life stage; if the first slope is greater than 1, it is determined that the charging port is in the second life stage; if the highest temperature of the temperature change curve is greater than the temperature threshold, it is determined that the charging port is in the third life stage; wherein, the first slope is the slope of the temperature change curve, and the second slope is the slope at the same position of the standard curve corresponding to the number of plug-in and unplugging times as the first slope.

[0074] The temperature change curve is drawn based on the actual maximum temperature of the charging port during charging as the number of plug-in and unplug cycles increases. In other words, it is an actual curve.

[0075] The standard curve is an ideal curve determined by the charging port designer, and is also the standard maximum temperature of the charging port during charging corresponding to an increase in the number of plugging and unplugging times.

[0076] The slope is divided into an average slope and an instantaneous slope. The average slope describes the overall performance over a period of time, while the instantaneous slope reveals the actual status at a specific moment. The instantaneous slope is more reflective of the actual risk or opportunity than the average slope. The slopes in the above embodiments are all instantaneous slopes.

[0077] Among them, the first slope is the slope of the point on the actual curve, the second slope is the slope of the point on the standard curve, the slope threshold is the ideal slope threshold determined by the designer and manufacturer, and the difference between the first slope and the second slope is greater than the slope threshold, which is the basis for determining the life stage of the charging port.

[0078] The following describes the first embodiment of the charging port life warning method of the present application.

[0079] like Figure 3 As shown, Figure 3A curve diagram of the first scheme of the charging port life warning method provided in the embodiment of the present application. The diagram shows two curves of "the maximum temperature increases with the increase in the number of plugging and unplugging", one of which is the actual curve and the other is the standard curve, and the trend of change is "stable → slowly rising → sharply rising". The first warning is the first life stage of the embodiment of the application itself, and the judgment basis is that the slope of the actual curve is 20% higher than the slope of the standard curve at the same number of plugging and unplugging times, that is, the difference between the first slope and the second slope is greater than 20% of the second slope, and 20% of the second slope is the first slope threshold, and the number of plugging and unplugging times is T1. The second warning is the second life stage of the embodiment of the present application, and the judgment basis is that the slope of the actual curve is greater than 1, that is, Figure 3 The angle corresponding to the slope in is 45°, and the number of plug-ins at this time is T2. Three warnings are the third life stage of the embodiment of the present application. The judgment basis at this time is that the highest temperature of the actual curve reaches the temperature limit, and the number of plug-ins at this time is T3.

[0080] In other words, for the number of plugging and unplugging times 0-T1, the two curves change relatively smoothly and almost overlap. When T1 is plugged and unplugged, the conditions of the first life stage are met, and then they begin to rise slowly as the curve changes. The number of plugging and unplugging times increases to T2, and the conditions of the second life stage are met. Then, as the curve changes, it begins to rise sharply. When the number of plugging and unplugging times increases to T3, the temperature threshold is reached and the third life stage is started.

[0081] For example, for an early warning, the user will be prompted to standardize the plugging and unplugging posture and clean foreign objects from the charging port.

[0082] For example, for the secondary warning, the user will be reminded that the life of the charging port is about to expire, and the user should arrange time to go to the 4S store to replace the charging port.

[0083] For example, for three warnings, the user will be reminded that the charging port has expired and he should go to the 4S store to replace the charging port as soon as possible.

[0084] Option 2

[0085] In some embodiments, the attribute information includes the actual number of plugging and unplugging times; based on the attribute information, the different life stages of the charging port are determined, including: obtaining the maximum number of plugging and unplugging times of the charging port; if the ratio of the actual plugging and unplugging times to the maximum plugging and unplugging times is greater than a first ratio, it is determined that the charging port is in the first life stage; if the ratio of the actual plugging and unplugging times to the maximum plugging and unplugging times is greater than a second ratio, it is determined that the charging port is in the second life stage; if the ratio of the actual plugging and unplugging times to the maximum plugging and unplugging times is greater than a third ratio, it is determined that the charging port is in the third life stage; wherein, the first ratio is less than the second ratio, and the second ratio is less than the third ratio.

[0086] The maximum number of plugging and unplugging times is a standard number determined by the life of the charging port itself.

[0087] The first ratio, the second ratio, and the third ratio are defined by the designer / manufacturer.

[0088] The second solution of the charging port life warning method of the present application is introduced below with a specific embodiment.

[0089] like Figure 4 As shown, Figure 4 A curve diagram of the second scheme of the charging port life warning method provided in the embodiment of the present application. The diagram shows a curve of "the number of plug-ins increases with time". The estimated plug-in life is the maximum number of plug-ins in this embodiment. When the actual number of plug-ins reaches 80% of the estimated plug-in life, a warning is triggered. When the actual number of plug-ins reaches 90% of the estimated plug-in life, a second warning is triggered. When the actual number of plug-ins reaches 100% of the estimated plug-in life, three warnings are triggered, of which 80% is the first ratio, 90% is the second ratio, and 100% is the third ratio. The first ratio is smaller than the second ratio, and the second ratio is smaller than the third ratio.

[0090] In other words, in Figure 4 On date t1, it is found that the ratio of the actual number of plugging and unplugging times to the estimated plugging and unplugging life reaches a first ratio, at which time an early warning is triggered. On date t2, it is found that the actual number of plugging and unplugging times reaches a second ratio of the estimated plugging and unplugging life, at which time a second early warning is triggered. On date t3, it is found that the actual number of plugging and unplugging times reaches a third ratio of the estimated plugging and unplugging life, at which time a third early warning is triggered.
