Description

Technical Field

[0001] The present invention relates to the technical field of vehicle batteries, and in particular to a method, device, electronic equipment and storage medium for inspecting a vehicle battery before sale. Background Art

[0002] With the booming new energy vehicle market, automotive batteries, as an essential and critical component of electric vehicles, play a crucial role in determining their proper operation and service life. New energy vehicles are equipped with numerous sensors and intelligent components, which frequently lead to battery failure. Furthermore, undelivered vehicles often sit for extended periods, during which time the battery inevitably loses charge. Therefore, a comprehensive and accurate battery inspection before a vehicle is sold is crucial for protecting consumer rights and improving vehicle sales quality.

[0003] However, traditional vehicle battery inspection methods rely heavily on manual labor, resulting in a cumbersome and complex process: first, the vehicle must be unlocked and powered on, then all sensor unlocking functions must be disabled on the vehicle's computer, the trunk must be opened, and then the vehicle must be powered off using a single button on the computer screen. After waiting three minutes, the battery voltage can be measured using a multimeter or other tool. This inspection process is not only inefficient but also prone to human error due to the numerous steps involved, making it difficult to ensure accurate results. Summary of the Invention

[0004] The purpose of the present invention is to provide a method, device, 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 errors, and make the inspection process more efficient and accurate.

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

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

[0007] Furthermore, the preset battery inspection conditions include inspection qualification determination conditions, and the inspection qualification determination conditions 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 power is greater than a preset power threshold, then the battery is determined to be qualified.

[0008] Furthermore, the preset battery inspection conditions also include: a battery damage determination condition and a battery power supply determination condition; The battery damage determination condition includes: within a second preset time after the battery meets the inspection precondition, if the minimum battery voltage is less than a second preset voltage threshold, then the battery is determined to be damaged, and the second preset voltage threshold is less than the first preset voltage threshold; The battery power feeding determination condition includes: determining that the battery is power feeding when the state information satisfies neither an inspection qualified determination condition nor a battery damaged determination condition.

[0009] Furthermore, the inspection precondition includes: if the vehicle DCDC output voltage is greater than or equal to a third preset voltage threshold for a duration exceeding a third preset time, the DCDC output voltage jumps to 0 or zero, and the power state jumps to power off, or the DCDC output voltage jumps to less than the third preset voltage threshold, then it is determined that the battery meets the inspection precondition and the battery voltage and battery power are continuously monitored; otherwise, it is determined that the battery does not meet the inspection precondition.

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

[0011] Furthermore, the comparison module includes an inspection qualification determination unit, a battery damage determination unit and a battery power feeding determination unit; The inspection qualification determination unit is configured to determine that the battery is qualified if the minimum battery voltage is greater than or equal to a first preset voltage threshold and the battery power is greater than a preset power threshold within a first preset time after the battery meets the inspection precondition; The battery damage determination unit is configured to determine that the battery is damaged if, within a second preset time after the battery meets the pre-check condition, the minimum battery voltage is less than a second preset voltage threshold, and the second preset voltage threshold is less than the first preset voltage threshold; The battery power feeding determination unit is used to determine whether the battery is powered on when the status information satisfies neither the inspection qualification determination condition nor the battery damage determination condition.

[0012] Furthermore, the comparison module includes a pre-check condition determination unit. When the vehicle DCDC output voltage is greater than or equal to a third preset voltage threshold for a duration exceeding a third preset time, the DCDC output voltage jumps to 0 or zero, and the power state jumps to power off, or the DCDC output voltage jumps to less than the third preset voltage threshold, the pre-check condition determination unit determines that the battery meets the pre-check condition and continuously monitors the battery voltage and battery power; otherwise, the pre-check condition determination unit determines that the battery does not meet the pre-check condition.

[0021] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily appreciate the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the various details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

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

[0023] In one embodiment, see Figure 1 As shown, a vehicle pre-sale battery inspection method, which is applied to a cloud server, includes: Receive preset battery inspection conditions. This step sets clear standards for subsequent inspections. Companies can preset inspection conditions tailored to their product positioning based on industry standards, vehicle characteristics, and customer needs, such as specific voltage ranges and charge thresholds. Unified standards ensure standardized inspections, avoid arbitrary manual judgment, and provide an objective basis for accurately assessing battery status, making the inspection process more scientific and consistent.

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

[0025] Status information is compared with preset battery inspection criteria to generate inspection results, which are then sent to a pre-set terminal. Comparing collected data with pre-set standards quickly generates inspection results, enabling automated judgment. This significantly improves inspection efficiency and reduces the time and effort required for manual comparisons. Inspection results are promptly sent to a pre-set terminal, allowing relevant personnel (such as sales staff and quality inspectors) to quickly access information and take timely action, such as replacement or repair, for unqualified batteries. This also facilitates centralized management and monitoring of vehicle status, providing data support for subsequent production and sales decisions and enhancing management convenience and traceability.

[0026] The vehicle pre-sale battery inspection method described in the present invention receives battery status information uploaded by the vehicle via a cloud server and automatically compares it with preset inspection conditions to generate inspection results. This eliminates the need for manual operation, greatly improving the efficiency of vehicle pre-sale battery inspections, reducing labor costs and human errors, and making the inspection process more efficient and accurate. Inspection results can also be fed back promptly, i.e., the inspection results are sent to a preset terminal, allowing relevant personnel to obtain the battery inspection status in a timely manner, facilitating rapid processing decisions for batteries that do not meet requirements, such as replacement or repair, helping to ensure the quality of pre-sale vehicles and improve consumer satisfaction. Furthermore, cloud-based inspections enable centralized management and monitoring of battery status information for a large number of vehicles, enabling companies to fully grasp 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 provides a direct indicator of the battery's immediate power supply capability. Different voltage values can indicate whether the battery is functioning properly. A low voltage may indicate a low battery or a fault. Battery charge directly indicates how much energy the battery can store. Accurately understanding the battery charge helps determine whether the battery can meet the requirements of vehicle startup and initial operation. By monitoring these two indicators, battery performance can be comprehensively and accurately assessed, allowing potential problems to be identified promptly.

[0028] As a preferred embodiment of the present invention, see Figure 2As shown, the preset battery inspection conditions include inspection qualification judgment conditions, and the inspection qualification judgment conditions 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 power is greater than a preset power threshold, then the battery is judged to be qualified.

[0029] Setting monitoring to "within the first preset time after the battery meets the pre-inspection conditions" ensures that the inspection is conducted within a specific and reasonable time period, eliminating interference from factors such as unstable vehicle operation. "Battery minimum voltage 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 obtained for vehicle startup and operation. "Battery charge greater than the preset charge threshold" ensures that the battery can maintain operation for a certain period of time from an energy storage perspective. This comprehensive assessment of multiple conditions avoids misjudgment based on a single indicator, accurately assesses battery compliance, and improves the accuracy of inspection results.

[0030] Clear judgment conditions facilitate rapid data processing by cloud servers, enabling automated inspections. This eliminates the need for manual repeated confirmation and analysis of ambiguous situations, shortens inspection time, and improves the efficiency of vehicle pre-sales inspections, enabling companies to more efficiently complete pre-delivery preparations, speed up vehicle launches, and enhance operational efficiency.

[0031] Exemplarily, 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 if, within the first preset time after the battery meets the pre-check conditions, the cloud server does not receive the battery voltage data uploaded by the vehicle for a fourth preset time, but the minimum battery voltage value collected during the remaining time periods within the first preset time is greater than or equal to the first preset voltage threshold, and the battery charge level is greater than the preset charge threshold, the battery is still deemed qualified. The fourth preset time is 90 seconds.

[0033] As a preferred embodiment of the present invention, see Figure 2 As shown, the preset battery inspection conditions also include: a battery damage determination condition and a battery power supply determination condition; the battery damage determination condition includes: within a second preset time after the battery meets the inspection precondition, if the minimum battery voltage is less than a second preset voltage threshold, then the battery is determined to be damaged, and the second preset voltage threshold is less than the first preset voltage threshold; the battery power supply determination condition includes: when the status information neither meets the inspection pass determination condition nor the battery damage determination condition, then the battery is determined to be power supplied.

[0034] The battery damage determination criteria are clearly defined: "Within a second preset time after the battery meets the pre-check conditions, if the minimum battery voltage is less than a second preset voltage threshold, the battery is considered damaged," and the second preset voltage threshold is lower than the first preset voltage threshold. This helps accurately identify severely faulty batteries, as low voltage could indicate a short circuit, plate damage, or other serious issues that could render the battery inoperable. Precise threshold settings and time limits prevent a damaged battery from being misidentified as being in another state, allowing for timely replacement of damaged batteries and ensuring vehicle safety and proper operation.

[0035] When the status information meets neither the inspection qualification criteria nor the battery damage criteria, the battery is deemed to be recharged. This determination method covers all intermediate states between non-qualified and non-damaged, avoiding ambiguity. In real-world scenarios, battery recharge is a common problem. Accurately identifying the recharge status allows staff to charge the battery promptly, preventing vehicle startup failures or performance degradation caused by recharge, thereby improving vehicle delivery quality and customer experience.

[0036] This preferred embodiment combines inspection qualification, battery damage, and battery power supply conditions to form a comprehensive and integrated battery status determination system. This system accurately determines whether a battery is normal, has a minor fault, or is seriously faulty, providing a clear basis for subsequent action. This helps improve the efficiency and accuracy of pre-sale vehicle inspections and optimize the entire vehicle sales process.

[0037] Exemplarily, 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 inspection precondition includes: if the vehicle DCDC output voltage is greater than or equal to the third preset voltage threshold for a duration exceeding the third preset time, the DCDC output voltage jumps to 0 or zero, and the power state jumps to power off, or the DCDC output voltage jumps to less than the third preset voltage threshold, then it is determined that the battery meets the inspection precondition and the battery voltage and battery power are continuously monitored; otherwise, it is determined that the battery does not meet the inspection precondition.

[0039] The inspection preconditions comprehensively consider the vehicle's DCDC output voltage and power status to eliminate interference with battery inspection caused by unstable voltage or other abnormal operating conditions during vehicle operation. When "the duration of the vehicle's DCDC output voltage being greater than or equal to the third preset voltage threshold exceeds the third preset time", it means that the vehicle's electrical system has been operating stably for a period of time, and the battery status monitored at this time is more representative. The conditions of "the DCDC output voltage jumps to 0 or zero, and the power status jumps to power off, or the DCDC output voltage jumps to less than the third preset voltage threshold" simulate common scenarios of normal vehicle power off or electrical system conversion. Monitoring the battery voltage and battery charge in this stable state can obtain more accurate battery performance data, avoid misjudgment due to fluctuations in the vehicle's electrical system, and improve the reliability of the inspection results.

[0040] Clear preconditions provide a clear basis for judgment during the inspection process. If the preconditions are not met, subsequent battery monitoring is not performed, avoiding ineffective inspections and saving computing resources and time. For example, during the initial vehicle startup or when an electrical system failure occurs, the DC-DC output voltage and power supply status are unstable. If a battery inspection is performed at this time, the data will fluctuate greatly and be of no reference value. However, monitoring after the preconditions are met makes the inspection process more scientific and rational, improving inspection efficiency.

[0041] This preferred implementation addresses the actual pre-sale conditions of vehicles, taking into account potential changes in the vehicle's electrical status during storage and transportation, and accurately identifies the appropriate time to inspect the battery. For example, upon arrival at a dealer's warehouse, staff can quickly determine whether an effective inspection is feasible based on this information. This ensures that inspections are closely aligned with the vehicle's actual condition, improving the relevance of inspections and better ensuring the quality of pre-sale battery inspections.

[0042] Exemplarily, 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 vehicle pre-sale battery inspection device, see 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 inspection conditions; The second receiving module 12 is used to receive battery status information uploaded by the vehicle; The comparison module 13 is used to compare the status information with the preset battery inspection conditions to generate an inspection result; The sending module 14 is used to send the inspection result 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 obtains vehicle battery status information. These two modules work in parallel, reducing 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 tedious and time-consuming manual operation, significantly improving the efficiency of pre-sale vehicle battery inspections and accelerating vehicle delivery.

[0046] The data transmission between the modules of the device is clear and orderly. The data obtained by the receiving module, the processing process of the comparison module and the results transmitted by the sending module can all be recorded and retained, which facilitates the company to uniformly manage the vehicle's pre-sale battery inspection data. When problems arise, 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] As a preferred embodiment of the present invention, the comparison module 13 includes an inspection qualification determination unit, a battery damage determination unit and a battery power feeding determination unit; The inspection qualification determination unit is configured to determine that the battery is qualified if the minimum battery voltage is greater than or equal to a first preset voltage threshold and the battery power is greater than a preset power threshold within a first preset time after the battery meets the inspection precondition; The battery damage determination unit is configured to determine that the battery is damaged if, within a second preset time after the battery meets the pre-check condition, the minimum battery voltage is less than a second preset voltage threshold, and the second preset voltage threshold is less than the first preset voltage threshold; The battery power feeding determination unit is used to determine whether the battery is powered on when the status information satisfies neither the inspection qualification determination condition nor the battery damage determination condition.

[0048] Each determination unit performs its assessment based on different preset times after the battery meets the pre-inspection conditions. This phased approach takes into account the battery's changing state at different points in time, making the inspection more realistic. For example, the pass determination unit focuses on the first preset time period, while the battery damage determination unit focuses on the second preset time period. These different time settings enable a more comprehensive assessment of the battery's performance and condition.

[0049] The logical relationship between each judgment unit is clear. By setting different judgment conditions, the battery status is divided into three situations: qualified, damaged and feeding. The staff can quickly take corresponding measures according to the judgment results, which improves the efficiency of the inspection work.

[0050] Accurate identification results provide a clear basis for subsequent repair and replacement work. Batteries identified as damaged can be promptly replaced to prevent malfunctions during vehicle use. Batteries identified as supply batteries can be charged or further inspected to determine if there are other potential issues. Batteries identified as qualified can be put into service directly to ensure normal vehicle delivery. Accurate assessment of battery status also allows for optimal inventory management. Damaged batteries can be promptly cleared to reduce space and costs. Supply batteries can be charged before being put into storage to improve inventory utilization. Qualified batteries can be stored and managed according to normal procedures to ensure inventory accuracy and effectiveness.

[0051] As a preferred embodiment of the present invention, the comparison module 13 includes an inspection precondition determination unit. The inspection precondition determination unit determines that the battery meets the inspection precondition and continuously monitors the battery voltage and battery power when the vehicle DCDC output voltage is greater than or equal to a third preset voltage threshold for a duration exceeding a third preset time, the DCDC output voltage jumps to 0 or zero, and the power state jumps to power off, or the DCDC output voltage jumps to less than the third preset voltage threshold; otherwise, the battery is determined not to meet the inspection precondition.

[0052] Clear inspection preconditions provide clear guidance for the inspection process. If the preconditions are not met, the device ceases subsequent monitoring, avoiding invalid data collection and processing, saving system resources and time. For example, during the initial vehicle startup, the DC-DC output voltage and power status are unstable. Directly checking the battery would yield useless data and waste resources. However, monitoring after the preconditions are met makes the inspection process more scientific and rational, improves inspection efficiency, and accelerates vehicle pre-sale inspections.

[0053] During pre-sale vehicle inspections, only by ensuring accurate battery inspections can the performance of delivered vehicles be guaranteed. This unit accurately determines pre-inspection conditions, allowing qualified batteries to proceed to the subsequent inspection process. This allows for timely identification and resolution of issues, preventing them from entering the market. For example, it can effectively identify abnormal battery conditions caused by electrical system instability, preventing the delivery of potentially problematic vehicles to consumers, safeguarding the company's brand image and ensuring the consumer experience and proper vehicle performance.

[0055] In one embodiment, the present invention further discloses a storage medium having a computer program stored thereon. When the computer program is executed by a computer, the computer executes the above-mentioned vehicle pre-sale 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 that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited to this. The storage medium in the embodiments of the present application can also be a circuit or any other system that can realize a storage function, used to store program instructions and / or data.

Any equivalent substitution or modification made by those skilled in the art based on the present invention is within the protection scope of the present invention.
