Description

Technical Field

[0001] This disclosure relates to the field of vehicle testing technology, specifically to a method and system for testing the structural safety of vehicle battery systems. Background Technology

[0002] The statements in this section are merely background information relating to this disclosure and do not necessarily constitute prior art.

[0003] As the automotive industry continues to develop, key components such as power battery systems, generators, and electric drives play crucial roles in vehicles. Mechanical damage to these critical components can significantly impact vehicle safety. Current technologies for detecting and mitigating these safety risks are somewhat limited, and certain extreme application scenarios remain unavoidable depending on the user group.

[0004] Current battery system detection technologies rely solely on vehicle collision sensors to identify faults and then disconnect the battery system. They cannot independently detect and identify the battery system structure, and the collision sensor signals essentially guarantee vehicle maintenance. When a commercial vehicle experiences a scrape or bottom impact, the system may continue operating without effective detection, but structural damage can cause internal cell compression and stress, increasing the risk of battery system failure and preventing timely warnings. Summary of the Invention

[0005] To address the aforementioned issues, this disclosure proposes a method and system for structural safety testing of vehicle battery systems. This method effectively conducts safety testing on key vehicle components (new energy power battery systems) and considers installing safety testing systems on key vehicle components. This enables vehicle manufacturers to monitor the safety status of vehicle power battery systems and ensures the safety performance of vehicles for end customers.

[0006] According to some embodiments, the present disclosure adopts the following technical solutions:

[0007] Vehicle battery system structural safety testing methods include:

[0008] Acquire basic vehicle data and set key deviation thresholds;

[0009] The system acquires actual vehicle operating data and transmits it to the vehicle's VCU for processing. It compares the actual operating data with the critical deviation threshold and transmits the processing result to the user terminal. The user terminal establishes communication with the maintenance client, which acquires the vehicle's maintenance and inspection data. If no fault occurs, the system updates the critical deviation threshold for safety inspection and confirms whether a safety inspection strategy upgrade is needed. If no upgrade is needed, the vehicle continues to operate.

[0010] The actual operating data is acquired by vehicle sensors; the vehicle sensors include a power battery system data detection sensor and a reference vehicle sensor; several power battery system data detection sensors are installed inside the power battery system, and the reference vehicle sensor is installed at the center of the vehicle chassis near the interior of the passenger compartment. The degree of risk at a given location is determined by comparing the data from different locations with the deviation of the reference vehicle sensor.

[0011] If an upgrade is required, the updated critical deviation threshold will be updated to the vehicle VCU.

[0012] According to some embodiments, the present disclosure adopts the following technical solutions:

[0013] The vehicle battery system structural safety testing system includes:

[0014] The data acquisition module includes vehicle sensors, including a power battery system data detection sensor and a reference vehicle sensor. Several of the power battery system data detection sensors are installed inside the power battery system, and the reference vehicle sensor is installed at the center of the vehicle chassis near the interior of the passenger compartment. The data acquisition module is used to acquire basic vehicle data and set key deviation thresholds.

[0015] The detection module is used to acquire actual vehicle operating data and transmit the actual operating data to the vehicle's VCU for processing. It compares the actual operating data with the critical deviation threshold and transmits the processing result to the user terminal. The user terminal establishes communication with the maintenance client. The maintenance client acquires the vehicle's maintenance and inspection data. When no fault occurs, it updates the critical deviation threshold for safety inspection and confirms whether a safety inspection strategy upgrade is needed. If no upgrade is needed, the vehicle continues to operate.

[0016] If an upgrade is required, the updated critical deviation threshold will be updated to the vehicle VCU.

[0017] According to some embodiments, the present disclosure adopts the following technical solutions:

[0018] A non-transitory computer-readable storage medium is provided for storing computer instructions, which, when executed by a processor, implement the vehicle battery system structural safety detection method.

[0023] Compared with the prior art, the beneficial effects of this disclosure are as follows:

[0024] This disclosure discloses a vehicle battery system safety testing method. By using sensors added inside the vehicle, the method transmits detected data from the power battery system sensors, vehicle vibration frequency, and vibration amplitude via wiring harness or wireless transmission to the vehicle management system or corresponding component management system. Following an information exchange strategy, the vehicle's operational data is then transmitted to the vehicle control unit (VCU) and the vehicle manufacturer's backend database. This enables vehicle manufacturers to monitor the safety status of the vehicle's power battery system, thereby ensuring the safety performance of the vehicle for end-users.

[0025] This disclosure discloses a vehicle battery system safety testing method. It involves adding a detection sensor to the vehicle's power battery system or its components. The number of sensors can be defined by the user, and the sensor is installed inside the power battery system to be tested. The location of the sensor can also be defined by the user. A reference vehicle sensor is placed at the center of the vehicle chassis, near the interior of the passenger compartment. This allows for monitoring of the vibration frequency, vibration amplitude, and stress location of the vehicle's power battery system and the entire vehicle. By comparing data from different locations with deviations from the overall vehicle sensor data, the degree of risk at that location is determined. This reduces the tedious calculation process, improves the efficiency of risk detection, and ensures the overall vehicle driving safety. Attached Figure Description

[0028] The present disclosure will be further described below with reference to the accompanying drawings and embodiments.

[0029] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this disclosure. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this disclosure. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] Example 1

[0032] One embodiment of this disclosure provides a method for structural safety testing of a vehicle battery system, including:

[0033] Acquire basic vehicle data, set critical deviation thresholds, acquire actual vehicle operating data, and transmit the actual operating data to the vehicle VCU for processing. Compare the critical deviation thresholds with the actual operating data, and transmit the processed data to the user terminal. The user terminal establishes communication with the maintenance client. The maintenance client acquires the vehicle's maintenance and inspection data. If no fault is detected, the critical deviation thresholds for safety inspection are updated, and it is confirmed whether a safety inspection strategy upgrade is required. If no upgrade is required, the vehicle continues to operate.

[0034] Among them, key data obtained from simulated road conditions using sensors installed on the vehicle before it is first put into the market serves as the basis for this strategy. The strategy is formulated based on the obtained data and whether the battery system has malfunctioned, in order to determine whether a malfunction has occurred.

[0035] Then, a determination is made as to whether an upgrade is needed, including:

[0036] A) For unidentified structural safety faults that occur in the market, retrieve sensor detection data from the backend, formulate and improve strategies, and upgrade accordingly.

[0037] B) Based on supplementary road condition data collected by the testing department, new fault conditions are identified, and strategies are improved and upgraded accordingly.

[0038] If an upgrade is required, the updated critical deviation threshold will be updated to the entire vehicle VCU.

[0039] As one embodiment, the actual operating data includes power battery system data, vehicle vibration frequency, and vibration amplitude. This disclosure adds a power battery system data detection sensor (the number can be defined by the user) to the power battery system or its components in the vehicle. The sensor is installed at a certain location in the power battery system to be detected (generally placed inside the power battery system, which can be defined by the user; the reference vehicle sensor is generally placed at the center of the vehicle chassis near the interior of the passenger compartment or at a location deemed more suitable by the vehicle manufacturer) to monitor the vibration frequency, vibration amplitude, and stress location of the vehicle's power battery system and the entire vehicle. By comparing the data from different locations with the deviation of the reference sensor for the entire vehicle, the degree of risk at that location can be determined.

[0040] After the power battery system data detection sensors and the reference vehicle sensors acquire data such as vibration frequency, vibration amplitude, and force location of the vehicle's power battery system and the whole vehicle, they transmit the actual operating data of the vehicle to the vehicle's VCU for processing via wiring harness or wireless connection and using an information interaction strategy, and then transmit it to the background database for storage. The information interaction strategy refers to the vehicle controller (VCU) receiving the signals emitted by the sensors and guiding the vehicle to issue an alarm according to a predetermined strategy.

[0041] The aforementioned sensors communicate via wiring harnesses or wireless communication as the information transmission medium, transmitting the detected data to the corresponding management system, vehicle controller, and user terminals (such as mobile phones, smartwatches, etc.). After receiving the actual vehicle operating data, the vehicle VCU detects the vibration frequency and amplitude of the vehicle during relevant testing processes (including but not limited to simulations of various road conditions and extreme road conditions, and simulations of faulty road conditions such as scraping and collisions), observes the changes in the data and curves, and statistically analyzes the test frequencies and vibration amplitudes obtained from various tests for normal and specific fault simulations, defining vibration frequency difference boundaries and vibration boundary difference boundaries to specify the risk level strategy threshold of the system.

[0042] The vehicle's VCU transmits the detected risk level to the vehicle's terminals (mobile app, smartwatch, vehicle center console, and vehicle big data center, etc.). Users or automakers can then consider conducting a vehicle inspection during maintenance or immediately at a car repair center or other qualified inspection facility based on the received risk level and area. The inspection results are then uploaded to the maintenance client to determine whether the risk or fault affects the safe use of the vehicle.

[0043] As one example, users can cancel the corresponding risk level prompt via mobile phone or central control to avoid being disturbed, but the corresponding detection data will be recorded and transmitted in real time.

[0044] As one embodiment, vehicles equipped with sensors undergo road condition testing to acquire a large amount of data. Automakers can obtain key sensor data (vibration frequency, vibration amplitude, and location) through road condition testing or other relevant equivalent tests. This data enables the analysis of the safety status of critical vehicle components. Experts then formulate critical deviation thresholds for safety detection strategies based on the test data and upload them to the vehicle's VCU (or the component's management system). Actual operating data is transmitted to the vehicle's VCU for processing. The critical deviation thresholds are compared with the actual operating data, and the processing results are transmitted to the user terminal. The user terminal establishes communication with the maintenance client, which obtains the vehicle's maintenance and inspection data. If no fault occurs, the critical deviation thresholds for safety detection are updated, and it is determined whether a safety detection strategy upgrade is needed. If no upgrade is needed, the vehicle continues to operate; if an upgrade is required, the updated critical deviation thresholds are updated to the vehicle's VCU.

[0045] The vehicle controller and its component management system analyze the safety status of key vehicle components based on the data obtained, according to the system policies updated in the vehicle's backend or the analysis policies already equipped in the vehicle. This data is then transmitted via wiring harnesses or wireless connections to central control units, mobile phones, and the vehicle manufacturer's big data center. Users can cancel notifications for the corresponding risk level via their mobile phones or central control units to avoid being disturbed. However, the relevant detection data will be recorded and transmitted in real time.

The data acquisition module is used to acquire basic vehicle data and set key deviation thresholds.

[0049] The detection module is used to acquire actual vehicle operating data and transmit the actual operating data to the vehicle's VCU for processing. It compares the actual operating data with the critical deviation threshold and transmits the processing result to the user terminal. The user terminal establishes communication with the maintenance client. The maintenance client acquires the vehicle's maintenance and inspection data. When no fault occurs, it updates the critical deviation threshold for safety inspection and confirms whether a safety inspection strategy upgrade is needed. If no upgrade is needed, the vehicle continues to operate.

[0050] If an upgrade is required, the updated critical deviation threshold will be updated to the vehicle VCU.
