[0001] This invention relates to the field of power battery management technology for new energy vehicles, and in particular to a method, device, vehicle, medium, and product for early warning of charging station replacement in new energy vehicles. Background Technology

[0002] With the transformation and upgrading of the automotive industry, new energy vehicles have become the mainstream trend in industry development. However, in practical applications, the charging sockets of plug-in hybrid and pure electric vehicles are prone to abnormal overheating due to wear and tear. If not replaced in time, this can lead to serious safety hazards. Therefore, timely replacement of charging sockets is crucial to ensuring the safe operation of vehicles. Existing monitoring methods are mainly based on temperature threshold alarms, which trigger an alarm and limit charging power when the temperature reaches a certain limit, requiring immediate replacement of the charging socket. However, this method fails to provide drivers with sufficient time to handle the situation, resulting in reduced charging efficiency and severely impacting the driving experience. Therefore, a simple early warning mechanism is urgently needed to identify the need for charging socket replacement in advance, thereby providing drivers with sufficient maintenance time and improving the overall operating efficiency of the vehicle. Summary of the Invention

It enables the detection of the status of the charging seat in new energy vehicles, monitors and warns of the health status of the charging seat, avoids safety problems caused by overheating of the charging seat, provides buffer time for the driver, and improves the operating efficiency of the vehicle.

[0004] According to one aspect of the present invention, a method for early warning of charging station replacement applied to new energy vehicles is provided, the specific steps of which include: Upon receiving a charging signal, obtain the remaining battery power. When the remaining battery power is detected to be within a first range, the maximum temperature of the charging dock is acquired in real time. When the maximum temperature of the charging dock is less than a first value, a temperature evaluation value is determined based on the maximum temperature of the charging dock, the temperature difference, and the number of charging cycles. The temperature difference is determined based on the maximum temperature and the minimum temperature of the charging dock. When the temperature assessment value is greater than or equal to the second value, a charging dock warning signal is generated, and a warning prompt message is generated based on the charging dock warning signal.

[0005] According to another aspect of the present invention, a charging station replacement early warning device for new energy vehicles is provided, the device comprising: The battery remaining power reading module is used to obtain the remaining battery power when a charging signal is received; The temperature acquisition module is used to acquire the maximum temperature of the charging dock in real time when the remaining battery power is detected to be within a first range, and to determine the temperature evaluation value based on the maximum temperature of the charging dock, the temperature difference, and the number of charging cycles when the maximum temperature of the charging dock is less than a first value; wherein, the temperature difference is determined based on the maximum temperature and the minimum temperature of the charging dock. The warning generation module is used to generate a charging dock warning signal when the temperature assessment value is greater than or equal to the second value, and to generate warning prompt information based on the charging dock warning signal.

[0006] According to another aspect of the present invention, a vehicle is provided, the vehicle comprising: One or more processors; Storage device for storing one or more programs; Sensors are used to collect charging dock temperature and charging signals; When the one or more programs are executed by the one or more processors, the one or more processors implement a charging dock replacement early warning method for new energy vehicles, as described in any embodiment of the present invention.

[0007] According to another aspect of the present invention, a storage medium containing vehicle-mounted computer executable instructions is provided, which, when executed by a vehicle-mounted computer processor, are used to perform a charging dock replacement early warning method for new energy vehicles, as described in any embodiment of the present invention.

Detailed Implementation

[0012] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0013] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, systems, products, or apparatus.

[0014] Figure 1 This invention provides a flowchart of a charging seat replacement early warning method for new energy vehicles. This embodiment is applicable to the detection and early warning of charging seat replacement in new energy vehicles. The method can be executed by a computing device composed of an on-board computer processor. This device can be implemented in hardware and / or software and configured in a new energy vehicle management system. This invention does not impose any limitations on this.

[0015] Figure 1 This invention provides a flowchart of a charging station replacement early warning method for new energy vehicles, which specifically includes the following steps: S101. Upon receiving a charging signal, obtain the remaining battery power.

[0016] Among them, the charging signal refers to the charging dock connection signal, which indicates whether the charging dock and charging gun of the new energy vehicle are connected. If connected, it means that the new energy vehicle is charging. The remaining battery capacity refers to the ratio of the battery's current remaining discharge capacity to its capacity when fully charged.

[0017] Specifically, when the charging socket of a new energy vehicle is connected to the charging gun, it indicates that the new energy vehicle is charging. During the charging process, the temperature of the charging socket is used to determine whether the charging socket needs to be replaced. This can ensure the reliability and accuracy of the charging socket replacement warning and avoid misjudgment.

[0018] S102. When the remaining battery power is detected to be within a first range, the maximum temperature of the charging dock is obtained in real time. When the maximum temperature of the charging dock is less than a first value, a temperature evaluation value is determined based on the maximum temperature of the charging dock, the temperature difference, and the number of charging cycles. The temperature difference is determined based on the maximum temperature and the minimum temperature of the charging dock.

[0019] The first range refers to the pre-set range of remaining battery capacity (State of Charge, SOC), which is the SOC range that the battery management system allows the vehicle to actually use. This range is typically determined based on the battery's chemical characteristics and safety. The first value refers to the pre-set temperature value, which is the highest temperature threshold for the charging dock corresponding to the charging dock replacement warning. If this temperature threshold is exceeded, a warning is issued, indicating that the charging dock needs to be replaced soon. The temperature difference refers to the difference between the maximum and minimum temperatures within the remaining battery capacity range. The number of charging cycles refers to the number of times the new energy vehicle has been charged. It is calculated as follows: when the charging dock is connected to the charging gun, the charging dock connection signal will show a rising edge, changing from 0 to 1, at which point the number of charging cycles is incremented by 1. The temperature assessment value is obtained by weighting the maximum temperature, temperature difference, and number of charging cycles, and is used to subsequently evaluate and generate the charging dock warning signal.

[0020] Specifically, Figure 2 This section presents temperature curves for the charging dock under different State of Charge (SOC) conditions. Since the charging dock temperature varies with SOC, and the degree of variation differs across SOC ranges, it's necessary to define SOC ranges. Within these pre-defined SOC ranges, the maximum temperature of the charging dock is acquired in real-time, and a judgment is made based on this maximum temperature. If the maximum temperature is lower than a first value, it indicates that the maximum temperature of the charging dock has not exceeded the maximum temperature threshold. Further judgment based on the temperature assessment value is then needed to determine whether an alert is required. By comparing the maximum temperature and the temperature assessment value multiple times, considering not only the maximum temperature but also the impact of the number of charging cycles and temperature variations, the alert results are more comprehensive and accurate, ensuring the accuracy of the charging dock's alerts.

[0021] S103. When the temperature assessment value is greater than or equal to the second value, a charging dock warning signal is generated, and a warning prompt message is generated based on the charging dock warning signal.

[0022] The second value refers to a pre-set temperature value used to determine whether the temperature assessment value is abnormal. The second value is obtained by using statistical methods to calculate a confidence interval based on historical data of the target vehicle, such as vehicle type and charging frequency, selecting a specific confidence level, and finally choosing the second value from the confidence interval. The charging dock warning signal is used to indicate the charging dock's warning status based on the maximum temperature and the temperature assessment value, facilitating reading by other components within the new energy vehicle and providing warning information.

[0023] Specifically, when the temperature assessment value is greater than or equal to the second value, it indicates that even if the maximum temperature does not exceed the highest temperature threshold of the charging dock corresponding to the charging dock replacement warning, the charging dock still poses a certain safety hazard after comprehensively considering the maximum temperature, temperature difference, and number of charging cycles, and therefore needs to be replaced soon. At this time, a charging dock warning signal is generated, along with a warning message, reminding the service station and driver that the vehicle's charging dock needs to be replaced soon and recommending that the vehicle be brought in for maintenance in the near future.

[0024] This invention reads the maximum temperature of the charging dock in real time within a specific SOC range and calculates a temperature assessment value based on the maximum temperature, temperature difference, and number of charging cycles. Multiple comparisons are made, taking into account not only the impact of the maximum temperature during charging but also the factors of temperature changes and the number of charging cycles. This multi-dimensional calculation and comparison avoids misjudgments and ensures the accuracy and reliability of the warning information. Furthermore, it provides a reminder when the charging dock is about to need replacement, allowing the driver time to react and ensuring vehicle operating efficiency.

[0025] The embodiments of the present invention are further expanded based on the above embodiments, wherein the same or corresponding technical terms as those in the above embodiments will not be repeated in this embodiment.

[0026] Figure 3 This invention provides a flowchart of a charging station replacement early warning method for new energy vehicles, which specifically includes the following steps: S201. During power-on initialization, obtain the warning signal identifier bit of the charging dock.

[0027] The charging dock warning signal flag is a flag stored in the new energy vehicle battery management system, used to indicate and record whether the charging dock needs to be replaced. Each time a charging dock warning signal is received based on the maximum temperature and temperature assessment value, the corresponding result is stored in the warning signal flag.

[0028] Specifically, during vehicle power-on initialization, the warning signal flag of the charging dock is read first. Based on the previously stored warning signal flag, it is determined whether to generate charging dock warning information to ensure accurate and timely prompts and warnings regarding the charging dock status.

[0029] S202. When the warning identifier is the first identifier, generate a charging dock warning signal and display the charging dock warning information corresponding to the charging dock warning signal on the display device.

[0030] The first identifier refers to the charging dock warning signal flag being set to 1.

[0031] Specifically, when the charging dock warning signal flag is 1, it indicates that the previously stored warning signal flag indicates that the charging dock needs to be replaced soon. At this time, a charging dock warning signal is generated and the warning information is displayed on the display device, reminding the service station and the driver that the charging dock needs to be replaced soon and suggesting that maintenance be carried out in the near future. This allows the driver time to handle the situation and ensures the smooth and safe operation of the vehicle.

[0032] S203. Upon receiving a charging signal, obtain the remaining battery power.

[0033] S204. When the remaining battery power is detected to be within a first range, the maximum temperature of the charging dock is obtained in real time. When the maximum temperature of the charging dock is less than a first value, a temperature evaluation value is determined based on the maximum temperature of the charging dock, the temperature difference, and the number of charging cycles. The temperature difference is determined based on the maximum temperature and the minimum temperature of the charging dock.

[0034] S205. When the temperature assessment value is greater than or equal to the second value, a charging dock warning signal is generated, and a warning prompt message is generated based on the charging dock warning signal.

[0035] S206. When the maximum temperature of the charging dock exceeds the third value, generate the charging dock warning signal, and display the charging dock warning information on the display device based on the charging dock warning signal.

[0036] The third value is the highest temperature threshold of the charging dock corresponding to the over-temperature alarm. If the temperature exceeds this threshold, it means that the charging dock temperature is too high and the charging dock needs to be replaced immediately.

[0037] Specifically, when the maximum charging temperature exceeds the third value, it indicates that the charging dock temperature is too high, exceeding the maximum temperature threshold corresponding to the over-temperature alarm, posing a safety hazard and requiring immediate replacement. At this time, a charging dock warning signal is generated and displayed on the screen, prompting the service station and driver to immediately replace the charging dock and recommending immediate repair. Simultaneously, to ensure safe vehicle operation, the charging power is limited to prevent the charging dock from overheating.

[0038] Furthermore, "generating a charging dock warning signal when the maximum temperature of the charging dock exceeds the third value, and displaying charging dock warning information on a display device based on the charging dock warning signal" also includes: When the maximum temperature of the charging dock is less than the third value and greater than the first value, a first warning signal is generated and the charging dock warning information is displayed on the display device.

[0039] The first warning signal is used to indicate that the charging dock can be repaired.

[0040] Specifically, when the maximum temperature of the charging dock is less than the third value but greater than the first value, it means that although the maximum temperature of the charging dock has not exceeded the maximum temperature threshold corresponding to the charging dock over-temperature alarm, it has exceeded the maximum temperature threshold corresponding to the charging dock replacement warning. In order to ensure the stable and safe operation of the vehicle, an alarm is still required to generate the first warning signal and display the charging dock warning information on the display device to remind the service station and the driver that the vehicle's charging dock will need to be replaced soon and it is recommended to bring it to the station for maintenance in the near future.

[0041] This invention employs multiple threshold values, including a first, second, and third value, to determine the maximum temperature of the charging dock and its assessed temperature. Multiple comparisons are made, comprehensively considering factors such as maximum temperature, number of charging cycles, and temperature variations, ensuring the comprehensiveness and reliability of the charging dock replacement warning. Furthermore, within the multiple ranges defined by the first, second, and third values, warning information is displayed on the display device according to the urgency of the charging dock replacement, providing drivers with ample decision-making and consideration time, thus ensuring the smooth and safe operation of the vehicle.

[0042] This embodiment of the invention further refines the above embodiments, and provides a further explanation of "determining the temperature evaluation value based on the maximum temperature of the charging dock, the temperature difference, and the number of charging cycles". For specific implementation methods, please refer to the detailed description of this embodiment. In this embodiment, the same or corresponding technical terms as those in the above embodiments will not be repeated.

[0043] Figure 4 This invention provides a flowchart of a charging station replacement early warning method for new energy vehicles, which specifically includes the following steps: S301. Upon receiving a charging signal, obtain the remaining battery power.

[0044] S302. When the remaining battery power is detected to be within the first range, the maximum temperature of the charging dock is obtained in real time.

[0045] S303. When the remaining battery power is within the first range, determine the temperature difference based on the maximum temperature and minimum temperature of the charging dock.

[0046] The maximum temperature of the charging dock is denoted as Tmax, the minimum temperature of the charging dock is denoted as Tmin, and the temperature difference is the difference between the maximum temperature and the minimum temperature, denoted as ΔT. The calculation method is: ΔT=Tmax-Tmin.

[0047] Specifically, when the remaining battery power is within the first range, the maximum temperature of the charging dock is read in real time for the calculation of the temperature difference ΔT and subsequent temperature assessment values, ensuring the accuracy of the calculation results and improving the reliability of the charging dock replacement warning.

[0048] S304. Determine the temperature assessment value based on the temperature difference, the maximum temperature of the charging dock, the number of charging cycles, and the corresponding weight values.

[0049] The temperature assessment value T' is calculated based on the temperature difference ΔT, the maximum temperature of the charging dock Tmax, and the number of charging cycles N. The calculation method is: T' = a*Tmax + b*ΔT + c*N. The corresponding weight values ​​are a, b, and c.

[0050] Specifically, Figure 5 This diagram shows the charging dock temperature for different numbers of charging gun connections, where Tthres0 is the first value, Tthres1 is the third value, and the number of charging gun connections represents the number of charging cycles. Since the charging dock temperature changes with the number of charging cycles, the impact of the number of charging cycles must be considered. A temperature difference assessment value is calculated based on the charging dock's maximum temperature Tmax, the temperature difference ΔT, and the number of charging cycles N. Weighting values ​​are used to adjust the importance of these three factors, making the charging dock replacement warning more accurate and reliable. This approach not only considers the damage caused by the maximum temperature but also the effects of thermal expansion and contraction due to temperature changes, and integrates the impact of the number of charging cycles on cycle life. This multi-dimensional approach to the temperature assessment value improves the reliability of the charging dock replacement warning. Furthermore, a weighting method is used to assign different weights to different factors, ensuring that the temperature assessment value, while comprehensively considering the maximum temperature, temperature difference, and number of calculations, focuses on the most important information based on the weights.

[0051] Furthermore, the weight values ​​are determined based on the following method: Based on the pre-determined vehicle type and number of charging cycles of the target vehicle, the corresponding weight value is obtained from the mapping table.

[0052] The mapping table contains confidence intervals calculated based on historical data. These confidence intervals are calculated using statistical methods based on historical data of the target vehicle, such as vehicle type and number of charging cycles, with a specific confidence level selected.

[0053] Specifically, a mapping table is constructed by using statistical methods to calculate confidence intervals, providing a reasonable and scientific range for selecting weight values. By selecting and setting weight values ​​from this range, the flexibility of weight values ​​is improved, and the degree of attention to different factors can be adjusted manually.

[0054] S305. When the temperature assessment value is greater than or equal to the second value, a charging dock warning signal is generated, and a warning prompt message is generated based on the charging dock warning signal.

[0055] In this embodiment of the invention, within a first range of remaining battery power, the temperature difference is determined based on the maximum and minimum temperatures of the charging dock. Compared to considering only the maximum and minimum temperatures, judging by the temperature difference is more accurate and can avoid the influence of external factors such as environmental factors. Furthermore, this embodiment of the invention calculates a temperature assessment value based on the maximum temperature of the charging dock, the temperature difference, and the number of charging cycles. When calculating the temperature assessment value, different weights are assigned to the maximum temperature of the charging dock, the temperature difference, and the number of charging cycles. While considering different factors, the degree of attention given to different factors is adjusted through weighting, making the calculation results more accurate and ensuring the accuracy and reliability of the charging dock warning.

[0056] Based on the above embodiments, the embodiments of the present invention will describe each step in chronological order. Figure 6 This invention provides a step diagram of a charging station replacement early warning method for new energy vehicles. In this embodiment, the same or corresponding technical terms as those in the above embodiments will not be repeated.

[0071] S416. If the system is powered off, the process ends; if the system is not powered off, the process returns to S404 and repeats S404-S415.

[0072] This invention reads the maximum and minimum temperatures of the charging dock in real time within a specific SOC range, and calculates a temperature assessment value based on the maximum temperature, temperature difference, and number of charging cycles. It comprehensively considers the impact of maximum temperature, temperature variations, and the number of charging cycles during the charging process. By comparing this value with first, second, and third values ​​multiple times, the reliability of the warning information is improved. Furthermore, it provides alerts based on the urgency of charging dock replacement, allowing drivers time to react, enhancing their driving experience, and ensuring vehicle safety.

[0073] Figure 7 This is a schematic diagram of a charging station replacement early warning device for new energy vehicles provided in an embodiment of the present invention. It is used to execute a charging station replacement early warning method for new energy vehicles as described in any of the above embodiments. Figure 7 As shown, the device includes: a battery remaining power reading module 51, a temperature acquisition module 52, and an early warning generation module 53.

[0074] The battery remaining power reading module 51 is used to acquire the remaining battery power when a charging signal is received. The temperature acquisition module 52 is used to acquire the maximum temperature of the charging dock in real time when the remaining battery power is detected to be within a first range, and to determine a temperature assessment value based on the maximum charging dock temperature, the temperature difference, and the number of charging cycles when the maximum charging dock temperature is less than a first value; wherein the temperature difference is determined based on the maximum and minimum temperatures of the charging dock.
