Description

Technical Field

[0001] The present invention relates to the field of energy storage, and particularly to a method and a terminal for managing battery swapping of shared batteries. Background Art

[0002] Currently, with the rapid development of the new energy vehicle industry, shared batteries and battery swapping modes have gradually become important energy replenishment methods for new energy vehicles. However, the existing battery swapping management methods mainly rely on maintenance at fixed intervals or simple battery swapping rules, and do not fully consider the actual power consumption behaviors of users, resulting in improper use by some users (such as frequent rapid acceleration, large current discharge, over-discharge, etc.), which accelerates the attenuation of the battery and affects the service life of the battery. In addition, the existing technology usually adopts a unified rental fee model, which cannot effectively motivate users to maintain good driving and charging / discharging habits. Summary of the Invention

[0013] If the average credit score of the user is greater than or equal to the fourth preset threshold, the rental fee will be restored to the initial value.

[0014] To solve the above technical problems, another technical solution adopted by the present invention is:

[0032] To describe the technical content, the achieved objectives and the effects of the present invention in detail, the following is described in conjunction with the embodiments and the accompanying drawings.

[0033] Please refer to Figure 1 , a battery swapping management method for a shared battery, comprising the steps of:

[0034] S1. Obtain the usage process data of the shared battery, and judge the health status of the shared battery based on the usage process data;

[0035] S2. Increase or decrease the user's credit score based on the health status;

[0036] S3. Perform hierarchical management on the shared batteries that the user can replace according to the credit score to restrict the user to reasonably use the shared batteries.

[0037] From the above description, it can be seen that the beneficial effects of the present invention are: by obtaining the usage data of shared batteries, evaluating the battery health status, and using this to affect the user's credit points, the user's battery replacement is constrained and managed through a points system. Compared with traditional battery replacement management methods, the difficulty of battery replacement management is reduced. At the same time, it can dynamically monitor the user's electricity usage behavior and constrain the user's electricity usage behavior through reasonable management and control, thereby prompting users to spontaneously develop correct electricity usage habits and avoid premature aging of shared batteries due to improper use.

[0038] For example, in a shared electric vehicle battery replacement system, every time a user replaces a battery, the battery replacement station will read the battery's recent usage data through the BMS (battery management system), including voltage, current, SOC (state of charge) and other parameters. For example, if a user frequently accelerates sharply, causing the current to fluctuate violently, or if the user has a long-term deep discharge (SOC is less than 5%), the credit points will be reduced after the system detects these anomalies. On the contrary, if the user maintains good driving habits, avoids high-current discharge, and replaces the battery in time when the SOC is less than 20%, the system will reward credit points. In the end, the credit points of bad users are reduced, and they can only exchange for batteries with lower health, while good users can get better quality batteries and improve the user experience.

[0039] Preferably, please refer to Figure 2 , the communication process of the above steps is as follows:

[0040] (1) The vehicle computer system reads the battery status data (such as voltage, current, temperature, SOC, etc.) provided by the shared battery pack (BMS) through the CAN bus, and displays the SOC information in real time on the vehicle computer.

[0041] (2) The shared battery pack (BMS) transmits detailed battery status information to the battery swap station (EMS) via the CAN bus so that the battery swap station can perform a battery health assessment.

[0042] (3) The battery swap station (EMS) exchanges data with the backend system (intelligent AI) through LAN, uploads the battery health status, battery swap records, etc., and receives the battery swap optimization strategy and credit points calculation rules provided by the backend system.

[0043] (4) The backend system (intelligent AI) combines big data computing to analyze the user's battery replacement records, calculate their credit points, and adjust the grade of the replaceable battery accordingly. It also provides battery health assessment and rental fee adjustment strategies.

[0044] (5) The battery swap APP (on the owner’s mobile phone) connects to the backend system through wireless communication to obtain the owner’s credit points, replaceable battery information, battery swap recommendations, etc., and provides a battery swap application interface.

[0045] (6) The battery swapping station (EMS) replaces the battery pack with the corresponding health level for the vehicle owner according to the credit score value calculated by the background system, and updates the system data.

[0046] In some embodiments, step S1 specifically includes the steps of:

[0047] Obtain the usage process data of the shared battery, including the current change data and the minimum discharge data during the historical usage process of the shared battery, and determine the loss state of the shared battery.

[0048] In some embodiments, step S1 further includes the step of: evaluating the loss state of the shared battery through the current change data and the minimum discharge data. Compared with the system that only manages battery swapping based on SOC, the present invention simultaneously considers the current change trend (such as large current charge and discharge) and the discharge depth (such as over-discharge), thereby providing a more accurate battery health assessment mechanism. For example, if a user has a relatively aggressive driving habit and frequently performs large current discharges (more than 10 times of discharge behaviors exceeding 0.9C within every 5 minutes), it is presumed that this user has frequent rapid acceleration or rapid braking behaviors. After the battery swapping station detects this behavior, it marks the health state of the battery as "high loss" and deducts the user's credit score accordingly. At the same time, when another user is detected during battery swapping that their lowest SOC was once lower than 5%, indicating that this user had a long-term deep discharge, the system also determines it as a loss behavior and deducts points. This method can more comprehensively evaluate the health state of the battery compared to the method that only uses SOC monitoring, thereby more effectively restricting user behaviors.

[0049] Based on the current change data, if there is a shared battery whose discharge current exceeds the first preset threshold and the over-discharge frequency exceeds the second preset threshold, it is determined that the user has a loss behavior for the currently used shared battery;

[0050] Based on the minimum discharge data, if there is a shared battery whose state of charge during discharge is lower than the third preset threshold, it is determined that the user has a loss behavior for the currently used shared battery;

[0051] Step S2 specifically includes the steps of:

[0052] When it is determined that the user has the loss behavior, the user's credit score is decreased;

[0053] When it is detected that the user has not had the loss behavior within the preset duration, the user's credit score is increased, and the value of the decrease is greater than the value of the increase.

[0054] As can be seen from the above description, the criteria for determining loss behavior are described in detail, and the rules for increasing and decreasing credit scores are clarified. Different from the traditional management methods based solely on the number of battery replacements or charging and discharging times, the present invention evaluates battery loss through over-limit determination of discharge current and monitoring of the lowest SOC, and sets up a reward and punishment mechanism for credit scores to enhance user restraint. For example, within the past 30 days, a certain user's shared battery had its discharge current exceed 0.9C 10 times within 5 minutes, and the lowest SOC was lower than 10% more than 5 times. Based on this, the system determines that the user has serious loss behavior and deducts 2 credit scores from the user. Another user did not have large-current discharges or an SOC lower than 10% during the same period, so the system rewards the user with 1 credit score. Since the increase in credit scores is less than the decrease, users need to maintain good behavior for a long time to restore their scores, which helps to guide users to develop good electricity-using habits and reduce the loss of shared batteries.

[0055] Please refer to Figure 3 , in some embodiments, step S3 specifically includes:

[0056] Perform hierarchical management on the shared batteries that users can replace according to the credit scores. When the user's credit score reaches the first preset range, allocate the shared battery with the highest level of health to the user; when the user's credit score reaches the second preset range, allocate the shared battery with the second-highest level of health to the user; when the user's credit score reaches the third preset range, allocate the shared battery with the lowest level of health to the user.

[0057] As can be seen from the above description, according to the user's credit score, the level of the replaceable battery is determined. Compared with the traditional unified battery replacement mode, the present invention can, through differential management, encourage users to maintain good usage habits, while reducing the unreasonable loss of shared batteries and improving the operating efficiency of the battery replacement system.

[0058] Specifically, the shared batteries are divided into three levels: high health (credit score 90 - 100 points), medium (credit score 80 - 89 points), and low (credit score < 80 points). When a user with a credit score of 92 points replaces the battery, the system will preferentially allocate a new battery with a higher level of health to the user, while a user with a credit score of only 75 points can only obtain a battery with a lower level of health. Since batteries with a high level of health have a longer battery life and a better user experience, most users will actively optimize their vehicle usage behavior to maintain a high credit score, and thus obtain a better-quality battery, thereby enabling users to spontaneously change their battery usage behavior, legitimate the operation, and delay the loss of the battery.

[0059] Please refer to Figure 4 , in some embodiments, step S3 further includes the steps:

[0060] Statistically calculate the average credit score of users. If the average credit score of a user is lower than the fourth preset threshold, increase the rental fee of shared batteries;

[0061] If the average credit score of a user is continuously lower than the fourth preset threshold for a preset duration, gradually increase the rental fee of shared batteries until the set upper limit is reached;

[0062] If the average credit score of a user is greater than or equal to the fourth preset threshold, restore the rental fee to the initial value.

[0063] From the above description, a dynamic adjustment mechanism for credit scores and rental fees is introduced. That is, users with low credit scores need to pay higher rental fees, and when the credit score is restored, the fees return to normal. Compared with the traditional fixed-rate management mode, the present invention can further restrict user behavior through economic means, making them more inclined to reasonably use shared batteries.

[0064] Specifically, calculate the average credit score of a user each month. When the credit score of this user this month < 80, upload this information to the background system, and the background system increases the rental fee for the next month of this user by 20%; and so on. When the credit scores of this user for two consecutive months are both < 80, the rental fee for the next month increases by 50%; when the credit scores of this user for three consecutive months are both < 80, the rental fee for the next month increases by 100%; when the credit score of this user is restored ≥ 80, the rental fee for the next month returns to the original price.

[0065] For example, if a user's credit score is 78 points, the battery swapping system automatically uploads the information of this user to the background and adjusts the rental rate for the next month, increasing it by 20%. If this user still does not improve in the next 2 months (the credit score is continuously lower than 80), the rental fee further increases by 50%. If the credit score of this user is continuously lower than 80 for 3 months, the rental fee for the next month doubles. On the other hand, if a user raises the credit score above 85 within 1 month, the rental fee for the next month returns to normal. This mechanism can effectively curb bad vehicle usage behaviors and at the same time encourage users to improve driving habits to reduce long-term economic losses.

[0066] Preferably, after step S3, step S4 is further included:

[0067] Obtain weather information and match it with the usage process data of the shared battery being tested. If there is extreme weather, shield the usage process data of the shared battery for the corresponding time period and do not participate in the test.

[0068] As can be seen from the above description, under extreme weather conditions (such as extreme cold, extreme heat, heavy rain, etc.), the battery performance may be affected by environmental factors, rather than abnormal discharge or SOC changes caused by user behavior. If not distinguished, it may lead to unfair deductions for users. Therefore, shielding these data can improve the scientificity and rationality of credit score evaluation. At the same time, using weather data for automatic matching can effectively reduce misjudgments caused by external environmental factors (such as a sudden drop in battery voltage due to low temperature), reduce unjust deductions, and improve the user experience. In addition, under extreme weather conditions, abnormal situations are likely to occur during users' driving processes, resulting in an increase in behaviors such as sudden acceleration or sudden braking. For example, tire skidding on rainy or snowy days and reduced visibility on foggy days can all lead to an increase in abnormal behaviors and battery loss. It is unfair to users to consider such losses as user driving problems. To improve the user experience, the data in this section is shielded and not detected.

[0069] Please refer to Figure 5 , a battery swapping management terminal 1 for shared batteries, includes a memory 2, a processor 3, and a computer program stored on the memory 2 and executable on the processor 3. When the processor 3 executes the computer program, it completes the steps in a battery swapping management method for shared batteries. That is, a carrier is provided to execute the above method.

[0070] In summary, the present invention provides a battery swapping management method and terminal for shared batteries. By obtaining the usage data of shared batteries, the health status of the batteries is evaluated, and the user's credit score is dynamically adjusted based on this status, thereby implementing hierarchical management of user battery swapping. Compared with traditional battery swapping management methods, the present invention can more accurately evaluate the user's battery usage habits through means such as current fluctuation analysis and SOC threshold monitoring, and restrain unreasonable usage behaviors through a credit score system. In addition, the present invention introduces a credit score and battery hierarchical management mechanism, enabling users with high credit scores to preferentially obtain batteries with higher health levels, while users with low credit scores can only obtain batteries with lower health levels, thereby encouraging users to develop good driving and charging / discharging habits. Further, the present invention also has a dynamic rental fee adjustment mechanism, so that users with low long-term credit scores need to pay higher rental fees, increasing the binding force for users to use batteries reasonably from an economic perspective. This method can not only effectively reduce the unreasonable loss of shared batteries, extend the battery life, but also improve the management efficiency of the battery swapping station, reduce the operating cost, and make the operation of the entire battery swapping system more scientific and reasonable.
