Description

Technical Field

[0001] This invention relates to the field of vehicle battery technology, specifically to a method, apparatus, electronic device, and storage medium for pre-sale vehicle battery inspection. Background Technology

[0002] In the current booming new energy vehicle market, the vehicle battery, as an indispensable key component of electric vehicles, plays a decisive role in the normal operation and lifespan of the vehicle. New energy vehicles are equipped with numerous sensors and intelligent components, making battery depletion a frequent occurrence. Meanwhile, vehicles not yet delivered often need to be parked for extended periods, during which time battery power will inevitably naturally decrease. Therefore, conducting a comprehensive and accurate inspection of the battery condition before a vehicle is sold is a crucial step in protecting consumer rights and improving the quality of vehicle sales.

[0003] However, traditional methods of checking car batteries rely heavily on manual operation, and the specific procedures are cumbersome and complex: first, the car must be unlocked and powered on; then, all sensor-based unlocking functions must be disabled on the vehicle's infotainment system; the trunk must be opened; then, a one-button power-off operation must be pressed on the infotainment screen; and only after waiting for 3 minutes can a multimeter or other tools be used to measure the voltage of the small battery. This inspection process is not only inefficient, but also prone to human error due to the numerous steps, making it difficult to ensure the accuracy of the inspection results. Summary of the Invention

[0004] The purpose of this invention is to provide a method, apparatus, electronic device, and storage medium for pre-sale vehicle battery inspection, which can improve the efficiency of pre-sale vehicle battery inspection, reduce labor costs and human error, and make the inspection process more efficient and accurate.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, the present invention discloses a method for pre-sale vehicle battery inspection, which is applied to a cloud server and includes: Receive preset battery check conditions; Receive battery-related status information uploaded by the vehicle; The status information is compared with the preset battery inspection conditions to generate inspection results, which are then sent to the preset terminal.

[0006] Furthermore, the status information includes battery voltage and battery charge.

[0007] Furthermore, the preset battery inspection conditions include inspection qualification judgment conditions, which include: within a first preset time after the battery meets the inspection preconditions, if the minimum battery voltage is greater than or equal to a first preset voltage threshold and the battery charge is greater than a preset charge threshold, then the battery is judged to be qualified.

[0008] Furthermore, the preset battery inspection conditions also include: battery damage determination conditions and battery power depletion determination conditions; The battery damage determination criteria include: if the minimum battery voltage is less than a second preset voltage threshold within a second preset time after the battery meets the preconditions for inspection, the battery is determined to be damaged, and the second preset voltage threshold is less than a first preset voltage threshold. The battery power failure determination criteria include: if the status information does not meet either the inspection qualification determination criteria or the battery damage determination criteria, then the battery is determined to be power failure.

[0009] Furthermore, the preconditions for inspection include: if the duration of the vehicle's DC-DC output voltage being greater than or equal to the third preset voltage threshold exceeds the third preset time, and the DC-DC output voltage jumps to 0 or empty, and the power state jumps to power-off, or the DC-DC output voltage jumps to less than the third preset voltage threshold, then the battery is determined to meet the preconditions for inspection, and the battery voltage and battery charge are continuously monitored; otherwise, the battery is determined not to meet the preconditions for inspection.

[0010] Secondly, the present invention discloses a pre-sale vehicle battery inspection device, comprising: The first receiving module is used to receive preset battery check conditions; The second receiving module is used to receive battery-related status information uploaded by the vehicle. The comparison module is used to compare the status information with preset battery inspection conditions and generate inspection results; The sending module is used to send the inspection results to a preset terminal.

[0011] Furthermore, the comparison module includes a qualified inspection unit, a battery damage inspection unit, and a battery power failure inspection unit; The inspection qualification determination unit is used to determine that the battery is qualified if the minimum value of the battery voltage is greater than or equal to the first preset voltage threshold and the battery power is greater than the preset power threshold within a first preset time after the battery meets the inspection preconditions. The battery damage determination unit is used to determine that the battery is damaged if the minimum battery voltage is less than a second preset voltage threshold within a second preset time after the battery meets the preconditions for inspection. The second preset voltage threshold is less than a first preset voltage threshold. The battery power failure determination unit is used to determine that the battery is power failure when the status information does not meet the inspection qualification determination conditions or the battery damage determination conditions.

[0012] Furthermore, the comparison module includes a pre-condition determination unit. When the duration of the vehicle's DC-DC output voltage being greater than or equal to a third preset voltage threshold exceeds a third preset time, the DC-DC output voltage jumps to 0 or empty, and the power status jumps to power-off; or when the DC-DC output voltage jumps to less than the third preset voltage threshold, the pre-condition determination unit determines that the battery meets the pre-condition and continuously monitors the battery voltage and battery charge. Otherwise, it determines that the battery does not meet the pre-condition.

[0013] Thirdly, the present invention discloses an electronic device, including a memory and a processor, wherein the memory and the processor are connected; the memory is used to store a program; and the processor is used to call the program stored in the memory to execute the above-described method for checking vehicle pre-sale batteries.

[0015] The present invention has the following unexpected beneficial effects: The vehicle pre-sale battery inspection method of this invention receives battery status information uploaded by vehicles via a cloud server and automatically compares it with preset inspection conditions to generate inspection results. This eliminates the need for manual operation, significantly improving the efficiency of pre-sale battery inspections, reducing labor costs and human error, and making the inspection process more efficient and accurate. Furthermore, it provides timely feedback on inspection results by sending them to preset terminals. Relevant personnel (such as sales staff and vehicle quality inspectors) can promptly obtain the battery inspection status, facilitating quick decision-making for non-compliant batteries, such as replacement or repair, thus helping to ensure pre-sale vehicle quality and improve customer satisfaction. In addition, cloud-based inspections enable centralized management and monitoring of battery status information from a large number of vehicles, allowing companies to comprehensively understand the overall status of vehicle batteries, providing strong data support for pre-sale vehicle management, and facilitating the optimization of vehicle sales processes and resource allocation.

[0020] Figure 4 A schematic diagram of the structure of the vehicle pre-sale battery inspection device according to an embodiment of the present invention is shown. Detailed Implementation

[0021] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0022] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0023] In one embodiment, see Figure 1 As shown, a method for checking vehicle pre-sale batteries, applied to a cloud server, includes: Receive preset battery inspection conditions. This step sets clear standards for subsequent inspections. Companies can preset inspection conditions that align with their product positioning, based on industry standards, vehicle characteristics, and customer needs, such as specifying particular voltage ranges and charge thresholds. Unified standards ensure standardized inspections, avoid the arbitrariness of human judgment, provide objective evidence for accurately assessing battery condition, and make the inspection process more scientific and consistent.

[0024] It receives battery-related status information uploaded by vehicles. By receiving real-time status information uploaded by vehicles, data collection is automated, eliminating the need for manual on-site collection. This not only saves labor costs but also obtains more comprehensive and accurate data, such as dynamic changes in voltage parameters. This real-time data reflects the actual condition of the battery during use or storage, providing rich information for accurate judgment, helping to identify potential problems, and improving the reliability of inspections.

[0025] The system compares the status information with preset battery inspection conditions to generate inspection results, which are then sent to a preset terminal. Comparing the collected data with preset standards enables rapid generation of inspection results, achieving automated judgment. This significantly improves inspection efficiency and reduces the time and effort required for manual comparison. The timely transmission of inspection results to the preset terminal allows relevant personnel (such as sales and quality inspectors) to quickly obtain information and take timely measures against substandard batteries, such as replacement or repair. Simultaneously, it facilitates centralized management and monitoring of vehicle status for enterprises, providing data support for subsequent production and sales decisions and enhancing management convenience and traceability.

[0026] The vehicle pre-sale battery inspection method of this invention receives battery status information uploaded by vehicles via a cloud server and automatically compares it with preset inspection conditions to generate inspection results. This eliminates the need for manual operation, significantly improving the efficiency of pre-sale battery inspections, reducing labor costs and human error, and making the inspection process more efficient and accurate. Furthermore, it provides timely feedback on inspection results by sending them to preset terminals, allowing relevant personnel to promptly obtain the battery inspection status and quickly make decisions regarding non-compliant batteries, such as replacement or repair. This helps ensure the quality of pre-sale vehicle inspections and improves customer satisfaction. In addition, cloud-based inspections enable centralized management and monitoring of battery status information from a large number of vehicles, allowing companies to comprehensively understand the overall status of vehicle batteries, providing strong data support for pre-sale vehicle management, and facilitating the optimization of vehicle sales processes and resource allocation.

[0027] As a preferred embodiment of the present invention, see Figure 2 As shown, the status information includes battery voltage and battery charge. Battery voltage directly reflects the battery's immediate power supply capability; different voltage values ​​indicate whether the battery is in normal working condition. A voltage that is too low may mean the battery is depleted or has a malfunction. Battery charge directly indicates the amount of electrical energy stored in the battery. Accurately monitoring the battery charge helps determine whether the battery can meet the needs of vehicle startup and initial operation. By monitoring these two indicators, battery performance can be comprehensively and accurately assessed, and potential problems can be identified in a timely manner.

[0028] As a preferred embodiment of the present invention, see Figure 2As shown, the preset battery inspection conditions include inspection qualification judgment conditions, which include: within a first preset time after the battery meets the inspection preconditions, if the minimum battery voltage is greater than or equal to a first preset voltage threshold and the battery charge is greater than a preset charge threshold, then the battery is judged to be qualified.

[0029] Setting monitoring within a "first preset time period after the battery meets the pre-existing inspection conditions" ensures that the inspection is conducted within a specific and reasonable timeframe, eliminating interference from factors such as unstable vehicle operation. "The minimum battery voltage is greater than or equal to the first preset voltage threshold" directly reflects the lower limit of the battery's power supply capacity; only when this first preset voltage threshold is reached can sufficient power be guaranteed for vehicle startup and operation. "The battery charge is greater than the preset charge threshold" ensures, from an energy storage perspective, that the battery can maintain operation for a certain period. By comprehensively judging multiple conditions, misjudgments based on a single indicator are avoided, accurately assessing the battery's qualification and improving the accuracy of inspection results.

[0030] Clear judgment criteria facilitate rapid data processing by cloud servers, enabling automated inspections without the need for repeated manual confirmation and analysis of ambiguous situations. This shortens inspection time, improves the efficiency of pre-sale vehicle inspections, and allows companies to complete pre-delivery preparations more efficiently, accelerating vehicle launches and enhancing operational efficiency.

[0031] For example, the first preset time is 10 minutes, the first preset voltage threshold is 12.1V, and the preset power threshold is 60%.

[0032] It should be noted that, within the first preset time period after the battery meets the pre-check conditions, if the cloud server does not receive the battery voltage data uploaded by the vehicle within the fourth preset time period, but the minimum value of the battery voltage collected in other time periods within the first preset time period is greater than or equal to the first preset voltage threshold, and the battery charge is greater than the preset charge threshold, the battery is still considered qualified. The fourth preset time period is 90 seconds.

[0033] As a preferred embodiment of the present invention, see Figure 2 As shown, the preset battery inspection conditions also include: battery damage determination conditions and battery power failure determination conditions; the battery damage determination conditions include: if the minimum battery voltage is less than a second preset voltage threshold within a second preset time after the battery meets the inspection preconditions, the battery is determined to be damaged, and the second preset voltage threshold is less than a first preset voltage threshold; the battery power failure determination conditions include: if the status information does not meet either the inspection qualification determination conditions or the battery damage determination conditions, the battery is determined to be power failure.

[0034] The system establishes clear criteria for determining battery damage: "If, within a second preset time period after the battery meets the pre-conditions for inspection, the minimum battery voltage is less than a second preset voltage threshold, the battery is deemed damaged," and the second preset voltage threshold is less than a first preset voltage threshold. This helps accurately identify batteries with serious faults, as excessively low voltage often indicates internal short circuits, damaged plates, or other severe problems rendering the battery unusable. Precise threshold settings and time limits prevent misclassifying damaged batteries as other conditions, allowing for timely replacement and ensuring vehicle safety and normal operation.

[0035] When the status information does not meet either the inspection pass criteria or the battery damage criteria, the battery is determined to be depleted. This determination method covers all intermediate states that are neither passable nor damaged, avoiding ambiguity. In real-world scenarios, battery depletion is a common problem. Accurately identifying the depletion status allows staff to promptly recharge the battery, preventing vehicle starting failures or performance issues caused by depletion, thus improving vehicle delivery quality and customer experience.

[0036] In this preferred embodiment, the inspection pass criteria, battery damage criteria, and battery depletion criteria are combined to form a comprehensive and complete battery condition assessment system. Whether the battery is normal, has a minor fault, or a serious fault, an accurate assessment can be obtained, providing a clear basis for subsequent handling measures. This helps improve the efficiency and accuracy of pre-sale vehicle inspections and optimizes the entire vehicle sales process.

[0037] For example, the second preset time is 3 minutes and the second preset voltage threshold is 11.5V.

[0038] As a preferred embodiment of the present invention, see Figure 3 As shown, the preconditions for inspection include: if the duration of the vehicle's DC-DC output voltage being greater than or equal to the third preset voltage threshold exceeds the third preset time, and the DC-DC output voltage jumps to 0 or empty, and the power state jumps to power-off, or the DC-DC output voltage jumps to less than the third preset voltage threshold, then the battery is determined to meet the preconditions for inspection, and the battery voltage and battery charge are continuously monitored; otherwise, the battery is determined not to meet the preconditions for inspection.

[0039] The preconditions for checking the battery status comprehensively consider the vehicle's DC-DC output voltage and power supply status, eliminating interference from voltage instability or other abnormal operating conditions during vehicle operation. When "the vehicle's DC-DC output voltage is greater than or equal to the third preset voltage threshold for a duration exceeding the third preset time," it indicates that the vehicle's electrical system has been operating stably for some time, making the monitored battery status more representative. Conditions such as "the DC-DC output voltage jumps to 0 or empty, and the power supply status jumps to power-off, or the DC-DC output voltage jumps to less than the third preset voltage threshold" simulate common scenarios of normal vehicle power-off or electrical system transitions. Monitoring the battery voltage and charge under these stable conditions provides more accurate battery performance data, avoids misjudgments due to fluctuations in the vehicle's electrical system, and improves the reliability of the inspection results.

[0040] Clearly defined prerequisites provide a clear basis for judgment in the inspection process. If these prerequisites are not met, subsequent battery monitoring should not be performed, avoiding unnecessary checks and saving computational resources and time. For example, during the initial vehicle startup or when there is an electrical system fault, the DC-DC output voltage and power status are unstable. If battery checks are performed under these conditions, the data will fluctuate significantly and be of no reference value. Monitoring only after the prerequisites are met makes the inspection process more scientific and reasonable, improving inspection efficiency.

[0041] This preferred embodiment takes into account the actual situation before vehicle sales, considering the possible changes in the electrical condition of the vehicle during storage and transportation, and accurately selects the appropriate time to inspect the battery. For example, after the vehicle arrives at the dealer's warehouse, staff can quickly determine whether an effective inspection can be carried out based on this condition, ensuring that the inspection work is closely integrated with the actual condition of the vehicle, improving the pertinence of the inspection, and better ensuring the quality of pre-sale battery inspections.

[0042] For example, the third preset time is 3 minutes and the third preset voltage threshold is 13.5V.

[0043] In one embodiment, the present invention discloses a pre-sale vehicle battery inspection device, see [link to relevant documentation]. Figure 4 As shown, the inspection device 10 includes a first receiving module 11, a second receiving module 12, a comparison module 13, and a sending module 14.

[0044] The first receiving module 11 is used to receive preset battery check conditions; The second receiving module 12 is used to receive battery-related status information uploaded by the vehicle; The comparison module 13 is used to compare the status information with preset battery inspection conditions and generate inspection results; The sending module 14 is used to send the inspection results to a preset terminal.

[0045] In this embodiment, each module performs its own function. The first receiving module 11 receives preset inspection conditions, and the second receiving module 12 acquires vehicle battery status information. The two work in parallel to reduce information acquisition time. The comparison module 13 quickly compares the data and generates results, and the sending module 14 promptly transmits the results. The entire process is coherent and efficient, avoiding the tediousness and time-consuming nature of manual operation, greatly improving the efficiency of pre-sale vehicle battery inspection, and accelerating vehicle delivery.

[0046] The data transmission between the various modules of the device is clear and orderly. The data acquired by the receiving module, the processing of the comparison module, and the results transmitted by the sending module can all be recorded and stored, which facilitates the unified management of vehicle pre-sale battery inspection data by enterprises. When problems occur, the data source can be quickly traced and the problem can be analyzed, providing strong support for optimizing the inspection process and improving vehicle-related technologies.

[0047] In a preferred embodiment of the present invention, the comparison module 13 includes a qualified inspection unit, a battery damage determination unit, and a battery power failure determination unit. The inspection qualification determination unit is used to determine that the battery is qualified if the minimum value of the battery voltage is greater than or equal to the first preset voltage threshold and the battery power is greater than the preset power threshold within a first preset time after the battery meets the inspection preconditions. The battery damage determination unit is used to determine that the battery is damaged if the minimum battery voltage is less than a second preset voltage threshold within a second preset time after the battery meets the preconditions for inspection. The second preset voltage threshold is less than a first preset voltage threshold. The battery power failure determination unit is used to determine that the battery is power failure when the status information does not meet the inspection qualification determination conditions or the battery damage determination conditions.

[0048] Each judgment unit makes its judgment based on different preset time intervals after the battery meets the pre-inspection conditions. This phased judgment method takes into account the battery's state changes at different points in time, making the inspection more realistic. For example, the inspection pass judgment unit focuses on the situation within the first preset time interval, while the battery damage judgment unit focuses on the situation within the second preset time interval. Different time settings can more comprehensively evaluate the battery's performance and condition.

[0049] The logical relationships between each judgment unit are clear. By setting different judgment conditions, the battery status is divided into three situations: qualified, damaged, and depleted. Staff can quickly take corresponding measures based on the judgment results, which improves the efficiency of the inspection work.

[0050] Accurate assessment provides a clear basis for subsequent repair and replacement work. Batteries deemed damaged can be replaced promptly to prevent malfunctions during vehicle use; batteries deemed depleted can be charged or further inspected to determine if other potential problems exist; batteries deemed acceptable can be put into direct use, ensuring normal vehicle delivery. Accurate battery condition assessment also allows for efficient inventory management. Damaged batteries can be promptly cleared from inventory, reducing space and costs; depleted batteries can be charged before being put back into storage, improving inventory utilization; and acceptable batteries can be stored and managed according to normal procedures, ensuring the accuracy and effectiveness of inventory.

[0051] In a preferred embodiment of the present invention, the comparison module 13 includes a pre-condition determination unit. When the duration of the vehicle's DC-DC output voltage being greater than or equal to a third preset voltage threshold exceeds a third preset time, the DC-DC output voltage jumps to 0 or empty, and the power state jumps to power-off; or the DC-DC output voltage jumps to less than the third preset voltage threshold, the pre-condition determination unit determines that the battery meets the pre-condition and continuously monitors the battery voltage and battery charge. Otherwise, it determines that the battery does not meet the pre-condition.

[0052] Clearly defined preconditions provide clear guidance for the inspection process. When these preconditions are not met, the device stops subsequent monitoring, avoiding invalid data collection and processing, and saving system resources and time. For example, during the initial stage of vehicle startup, the DC-DC output voltage and power status are unstable. Directly checking the battery would yield data that is not valuable and would be a waste of resources. Monitoring only after the preconditions are met makes the inspection process more scientific and reasonable, improves inspection efficiency, and speeds up the pre-sale vehicle inspection process.

[0053] In pre-sale vehicle inspections, ensuring the accuracy of battery checks is crucial to guaranteeing the performance of delivered vehicles. This unit accurately assesses pre-inspection conditions, ensuring that only compliant batteries proceed to subsequent inspections. It promptly identifies and addresses issues, preventing problematic batteries from entering the market. For example, it effectively identifies abnormal battery conditions caused by electrical system instability, avoiding the delivery of potentially defective vehicles to consumers, thus protecting the company's brand image, and ensuring a positive user experience and optimal vehicle performance.

[0054] In one embodiment, the present invention also discloses an electronic device, including a memory and a processor, wherein the memory and the processor are connected; the memory is used to store a program; and the processor is used to call the program stored in the memory to execute the above-described pre-sale vehicle battery inspection method.

[0055] In one embodiment, the present invention also discloses a storage medium storing a computer program, which, when run by a computer, performs the above-described pre-sale vehicle battery inspection method.

[0056] The storage medium includes flash memory, hard disk, multimedia card, card-type memory, random access memory (RAM), static random access memory (SRAM), programmable read-only memory (PROM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), magnetic memory, magnetic disk, optical disk, etc. The storage medium is any other medium capable of carrying or storing desired program code in the form of instructions or data structures and accessible by a computer, but is not limited to this. In the embodiments of this application, the storage medium can also be a circuit or any other system capable of implementing storage functions for storing program instructions and / or data.

[0057] The above embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention.
