Battery test chucking
1. Product Overview
Designed for automated testing of power and consumer batteries, this chucking uses 6061-T6 aviation aluminum structure, achieving high-precision electrical connection and mechanical fixing via CNC machining and conductive anodizing. It supports cylindrical/prismatic/pouch batteries for cycle life and capacity fade tests in R&D labs and production lines.
2. Core Features
(1) Low-resistance Conductive Structure
Copper-aluminum composite contacts (surface resistance ≤0.5mΩ)
Conductive anodizing (1-3μm) ensures ≤5% resistance fluctuation after 100,000 insertions
(2) Micron-level Positioning
5-axis CNC machined slots (tolerance ±0.03mm) for ±0.1mm tab alignment
Elastic clamping compensates battery size variation (±0.5mm)
(3) Aging-resistant Design
T6 heat-treated aluminum (hardness ≥130HB) withstands 200℃
PEEK insulating parts (≥1000V withstand voltage), UL94-V0 compliant
(4) Quick-change Module Design
Module replacement ≤2 minutes, 0.1mm thickness adjustment
Compatible with M4/M6 threads for various test equipment
