AI Technical Summary

Technical Problem

Existing lithium-ion battery roller testing equipment suffers from insufficient accuracy in terrain simulation, lack of dynamic working condition control capabilities, and easy failure of the latch structure, resulting in weak correlation between test results and actual scenarios, and inconvenient operation.

Method used

The modular roller assembly design, combined with a stepless speed-regulating motor and hydraulic cylinder, enables the simulation of complex terrain and precise speed control. The opening, closing and locking of the cover plate are simplified through the slide rail, flange and buckle plate structure, and multiple locking is achieved using set screws and multiple sets of flange-buckle plate structures.

Benefits of technology

It enables diverse simulations of complex terrains, precisely controls the drum speed, improves testing efficiency, avoids the risk of locking failure, and enhances the dynamic reliability and ease of operation of the test.
