Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vibration testing, and particularly relates to a new energy automobile battery test platform and a test method. BACKGROUND

[0002] Under the background of rapid development of the new energy automobile industry, the performance and safety of the power battery as a core component directly determine the endurance, service life and driving safety of the vehicle. During the driving of the vehicle, the battery will be subjected to vibration impact from different road conditions for a long time, such as slight bumping on urban asphalt roads, severe vibration on rural dirt roads, and continuous oscillation on highways. These vibrations may cause the internal structure of the battery to loosen, the electrode contact to be poor, and even cause short circuit, liquid leakage and other serious faults. Therefore, simulating the vibration environment under various road conditions through a test platform to test the reliability of the battery is a key link to ensure the quality of new energy automobiles.

[0003] At present, the new energy automobile battery test platform on the market has obvious defects in vibration simulation. The vibration mechanism of the existing test platform is designed with fixed parameters, and the initial deformation of the vibration spring is not adjustable, resulting in single vibration amplitude and inability to reproduce the vibration differences under different road conditions. For example, when testing urban road conditions, a smaller vibration amplitude is required, and when testing off-road conditions, a larger vibration amplitude is required. The fixed amplitude vibration test is difficult to cover diversified actual scenarios, so that the reference value of the test result is limited, and it is difficult to accurately simulate the dynamic vibration characteristics under complex road conditions. This limitation may cause the battery to not experience the extreme vibration conditions that may be encountered in actual use during testing, thereby hiding potential structural hazards. For example, some batteries may perform stably in fixed amplitude testing, but may crack the shell and loosen the wiring under a larger amplitude vibration, which poses a safety risk to vehicle driving. Therefore, there is an urgent need for improvement. SUMMARY
