Solution Overview
Problem
Existing battery bending test methods fail to accurately simulate real-world bending conditions, leading to inadequate evaluation of safety performance due to issues like battery slippage, limited bending angles, and inability to control bending morphology.
Innovation Solution
A battery bending test system with a fastening device, pressing device, and load-bearing device that allows precise control over bending angles and morphology, enabling batteries to be securely held and bent at angles ranging from 0 to 180 degrees, using an angular adjustment element to form a variable angle between the fastening device and a reference surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional fastening device with fixed angle is used, then the device structure is simple, but the bending angle is limited and cannot simulate real-world conditions
Solution Approach 1:
The fastening device incorporates an angular adjustment element that enables dynamic change of the inclined surface angle relative to the reference surface. This allows the bending angle to be adjusted from 0 to 180 degrees, transforming a static structure into a dynamic one that can adapt to different test requirements while maintaining reasonable structural complexity through modular design.
Solution Approach 2:
The patent changes the geometric parameter of the fastening device by introducing an adjustable angle mechanism. The inclined surface angle can be varied to achieve different bending angles, allowing the system to simulate various real-world bending conditions without requiring multiple fixed-angle devices.
2Reliability
If the fastening device holds the battery securely, then battery slippage is prevented, but the bending morphology control becomes limited
Solution Approach 1:
The pressing device applies localized pressure to specific regions of the battery through a pressing head that can be positioned at different locations. This allows secure holding of the battery body while independently controlling the bending morphology at the pressed region, achieving both reliability and precision through spatially differentiated action.
Solution Approach 2:
The system separates the functions of battery holding and bending application into distinct components: the fastening device with inclined surface provides secure holding, while the pressing device applies controlled bending force. This functional segmentation allows each component to optimize its performance without compromising the other.
3Ease of operation
If the pressing device applies force perpendicular to the reference surface, then the bending force is easy to control, but the bending angle simulation is insufficient
Solution Approach 1:
The pressing device is designed to move along the inclined surface of the fastening device, transforming the simple perpendicular pressing action into a dynamically adjustable operation. By combining the perpendicular pressing force with the adjustable inclined angle, the system maintains ease of force control while achieving accurate simulation of various bending angles and conditions.

AI summary
A battery bending test system includes a fastening device having an inclined surface configured to hold a battery; a pressing device configured to press the battery to bend; and a load-bearing device configured to bear the fastening device, the load-bearing device having a reference surface for bearing the fastening device. A first angle Ø is formed between the inclined surface and the reference surface. The range of the first angle Ø is 0°<Ø<90°. The battery bending test system and method can precisely control the bending angle and bending morphology of the battery, and reasonably evaluate the safety performance of the battery when subjected to the bending force, thus meeting expectations of the safety test.
