[0024] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art should fall within the scope of protection of this application.

[0025] First, let's introduce one of the application scenarios of the charging strategy adjustment in this application. Electric vehicles are vehicles that consume electrical energy and rely on electrical energy for power during driving. When the driving range of an electric vehicle is insufficient, it needs to be charged in time to ensure the normal operation of the vehicle.

[0026] When charging an electric vehicle, the charging gun is inserted into the charging socket of the electric vehicle, and AC power is used to charge the battery of the electric vehicle. Since the charging gun and the charging socket adopt a plug-in structure, repeated plugging and unplugging of the charging gun and the charging socket can easily cause wear and tear, and there is also the possibility of poor plugging. This leads to an increase in the contact resistance between the charging gun and the charging socket, excessive temperature of the charging port, and low charging safety.

[0027] It should be noted that the charging strategy adjustment in this application can be applied not only to electric vehicles, but also to various motorized devices powered by electricity, such as electric bicycles and electric motorcycles. The specific application areas of the charging strategy adjustment are not limited.

[0028] To address the aforementioned problems, this application provides a charging strategy adjustment method to improve charging safety, such as... Figure 1 As shown, the method includes the following steps:

[0029] S101. Obtain charging-related information of the device to be charged. The charging-related information includes at least one piece of information characterizing the changing trend of the charging port temperature of the device to be charged within a preset time period.

[0030] In this application, the device to be charged can be an electric vehicle, or a motorized device that relies on electric energy for power, such as an electric bicycle or an electric motorcycle. The specific implementation of the device to be charged is not limited here.

[0031] As an example, charging-related information can be at least one piece of information that characterizes the trend of the charging port temperature of the device to be charged within a preset time period. For example, charging-related information can involve information collected within several time periods. By using the information collected within these time periods, the trend of the charging port temperature of the device to be charged within the corresponding time period can be found. The specific amount of information is not limited.

[0032] The applicant discovered that the temperature rise rate of the charging port typically exhibits a statistically regular pattern over a period of time, which can be used to predict the risk of overheating. Therefore, as an example, charging-related information can include the temperature rise rate of the charging port within a preset time period, using this rate as one indicator of the trend in the charging port temperature of the device being charged within that preset time period. This temperature rise rate can be the ratio of the maximum temperature difference of the charging port within that preset time period to the difference in the corresponding time interval. The following formula serves as an example of the temperature rise rate:

[0033] ΔV=ΔTemp / ΔT

[0034] ΔTemp=ΔTemP maxrange -ΔTemP minrange

[0035] ΔT=MIN(T,t maxrange -t minrange )

[0036] Wherein, ΔV is the temperature rise rate, ΔTemp is the maximum temperature difference within time period T, and ΔT is the minimum value of the time difference between the maximum and minimum values ​​of the charging port temperature at time T.

[0037] In other examples, the charging-related information may not directly carry the temperature rise rate, but instead carry the measured value of at least one charging port temperature obtained within a preset time period. The temperature rise rate of the charging port within the preset time period can be calculated using this measured value.

[0038] Here, with Figure 1 Taking the method executed by the cloud server as an example, this demonstrates the interaction scenario between the cloud server and the device to be charged:

[0039] like Figure 2 As shown, the interaction between the cloud server and the device to be charged may include the following steps: 201. The cloud server obtains charging-related information from the device to be charged; 202. The cloud server calculates the temperature rise rate; 203. The cloud server determines the device to be adjusted; 204. The cloud server sends an update charging strategy command to the device to be charged; 205. The device to be charged updates the charging strategy. Specifically, the cloud server obtains the aforementioned charging-related information from the device to be charged. This charging-related information can be a temperature rise rate calculated by the device to be charged, which the cloud server directly obtains.

[0040] like Figure 3As shown, the interaction between the cloud server and the device to be charged may also include the following steps: 301. The cloud server obtains charging-related information from the device to be charged; 302. The cloud server determines the device to be adjusted; 303. The cloud server sends an update charging strategy command to the device to be charged; 304. The device to be charged updates the charging strategy. This charging-related information may also be at least one measured charging port temperature value from the device to be charged. After obtaining this charging port temperature value, the cloud server calculates the temperature rise rate in the cloud.

[0041] It is understandable that the temperature change trend of the charging port of the device to be charged within the preset time period may include other possible scenarios besides those listed above. Furthermore, the specific implementation of the change trend can be determined by the designer based on their actual needs, and no restrictions are imposed here.

[0042] As an example, the start time of the preset time period can be set to the time when the device to be charged starts charging. This allows for the rapid detection of vehicles that may overheat during the current charging process, ensuring that the warning is issued as early as possible. The start time of the preset time period can also be set to other times as needed, without any specific limitations.

[0043] As an example, charging-related information may also include one or more of the following: the charging status of the device to be charged, the charging start time, and the charging end time. In one embodiment, the number of times the charging gun and the charging socket are plugged in and unplugged can be calculated based on the charging status, the charging start time, and the charging end time of the device to be charged.

[0044] Determining whether to issue a charging gun life warning to the user based on the number of times the charging gun is plugged in and out, one possible implementation is: if the number of times the charging gun is plugged in and out is greater than or equal to a threshold number of times the charging gun is plugged in and out, then a first warning message is pushed to the user. The first warning message may include charging gun life information and a reminder to the user to replace the charging gun. The threshold number of times the charging gun is plugged in and out can be determined based on the maximum theoretical number of times the charging gun is worn out.

[0045] Determining whether to issue a charging dock lifespan warning to the user based on the number of times the charging dock is plugged in and out, one possible implementation is: if the number of times the charging dock is plugged in and out is greater than or equal to a threshold number of times the charging dock is plugged in and out, then a second warning message is pushed to the user. The second warning message may include charging dock lifespan information and a reminder to the user to replace the charging dock. The threshold number of times the charging dock is plugged in and out can be determined based on the maximum theoretical number of times the charging dock is worn out.

[0046] It is understood that, in addition to including at least one piece of information representing the trend of the charging port temperature of the device to be charged within a preset time period, the charging status of the device to be charged, the charging start time, and the charging end time, charging-related information may also include, in practical applications, the identification code of the device to be charged, and user personal information related to the device to be charged. The specific information contained in the charging-related information is not limited here.

[0047] It is understandable that, in addition to the methods mentioned above, other warning methods may be excluded when providing lifespan warnings to users based on the number of insertions and removals. The actual warning method can be determined according to the designer's needs.

[0048] As an example, after obtaining the above-mentioned charging-related information, it is possible to preprocess the charging-related information to clean up dirty data, making the data contained in the charging-related information "cleaner" and improving the efficiency of subsequent data processing. One possible implementation method is to analyze the proportion of duplicate values, null values, invalid values, and out-of-limit values ​​in the charging-related information, and adopt different data preprocessing strategies to process these values. These strategies may include data deletion, extreme value replacement within X seconds before and after, and interpolation value replacement. It is worth noting that in addition to the various optional situations listed above, other optional situations are not excluded. Furthermore, the method of preprocessing charging-related information can be selected according to the actual needs of the designer, and no limitation is made here.

[0049] S102. Based on charging-related information and empirical statistical values ​​of charging port temperature, determine the device to be adjusted so that the charging strategy of the device to be adjusted can be updated. The device to be adjusted is the device to be charged that has a risk of overheating of the charging port temperature.

[0050] To determine the device to be adjusted based on empirical statistics of charging-related information and charging port temperature, the following two optional implementation methods can be used:

[0051] Option 1: The aforementioned empirical statistical value can be the historical temperature rise rate of the charging port. In an exemplary scenario, this historical temperature rise rate can be pre-stored in the cloud or reported to the cloud by the device to be charged along with charging-related information. The method for obtaining the historical temperature rise rate is not limited here. Devices to be charged whose charging port temperature rise rate within a preset time period is greater than this historical temperature rise rate are identified as devices requiring adjustment.

[0052] Option 2: When the temperature change trend of the charging port of the device to be charged within a preset time period is consistent with the measured temperature of at least one charging port obtained within the preset time period, the empirical statistical value can be a warning temperature value of the charging port. This warning temperature value can be pre-stored in the cloud or reported to the cloud by the device to be charged along with charging-related information. The method of obtaining the warning temperature value is not limited here. The number of measured values ​​greater than or equal to the warning temperature value is determined, and the devices to be charged whose number is greater than or equal to a certain threshold are identified as devices to be adjusted. The number can be the total number of measured values ​​greater than or equal to the warning temperature value, or the number of measured values ​​that are consecutively greater than or equal to the warning temperature value over time. The method of selecting this number is not limited here.

[0053] It is understandable that, in addition to the two options mentioned above, other methods can be used to determine the equipment to be adjusted in practical applications, which are not limited here.

[0054] It should be noted that the device to be adjusted is a device whose charging port temperature is at risk of overheating. In other words, under one possible scenario, the device to be adjusted is not currently overheating, but it is predicted that it may overheat after a period of time. Therefore, it is necessary to provide an early warning of this overheating risk.

[0055] As an example, updating the charging strategy can be to update the charging current of the device to be adjusted, for example, by reducing the charging current, or it can be to update the charging time of the device to be adjusted, for example, by changing the total charging time or by performing intermittent charging. The specific implementation of the charging strategy is not limited here.

[0056] Taking the interaction scenario between the cloud server and the device to be charged as an example, the above charging strategy can be generated on the cloud server and sent to the device to be adjusted, and the device to be adjusted can adjust the charging according to the charging strategy. Alternatively, it can be pre-stored on the device to be charged, and the cloud server sends a charging strategy adjustment instruction to the device to be adjusted. The device to be adjusted reads the local charging strategy according to the instruction and makes corresponding adjustments. The method of updating the charging strategy is not limited here.

[0057] As an example, updated charging strategy information can be pushed to users, allowing them to know the charging details, including the remaining time, and thus improve their user experience.

[0058] As an example, after identifying a device to be charged that has a risk of overheating at its charging port based on the above scheme, a tag can be set for the device to be charged, and the device with the tag can be identified as a device to be adjusted.

[0059] The technical solution provided in this application monitors the temperature of the charging port of the device to be charged, statistically analyzes the temperature change trend of the charging port of the device to be charged within a preset time period, and updates the charging strategy of the device to be charged in a timely manner for devices with a risk of overheating of the charging port, so as to avoid overheating and improve charging safety.

[0066] Optionally, the start time of the preset time period is the time when the device to be charged begins charging.
