Secondary Cells Testing TRIZ Cases
- Battery Parameter Estimation Under Low Diffusion Length Conditions
Diffusion-length-based concentration modeling improves battery SOC and health estimation when standard single-particle models fail at low diffusivity.
- Battery Temperature Control with State-Based Cooling Thresholds
Adaptive battery temperature ranges during idle and charge-discharge states cut air-conditioning cycles, lower control power use, and preserve output.
- Lead Film OCT Inspection for Internal Battery Void Detection
OCT scans the lead film-lead tab interface to detect internal gaps in batteries, improving fusion quality checks and leakage prevention.
- Battery Parameter Estimation Under Low Diffusivity Conditions
Diffusion-length-based concentration modeling improves battery SOC and health estimation when low diffusivity makes single-particle models inaccurate.
