Pouch Cell Battery Test Fixture High Current Clamp for Laboratory and Production Testing

Product Overview

This high-performance pouch cell battery test fixture is engineered to deliver stable, low-impedance electrical connections during demanding cell characterization, formation, and high-rate cycling procedures. By integrating precision-machined contact interfaces with robust mechanical clamping, the equipment eliminates contact variability and minimizes parasitic resistance, ensuring that measured electrochemical properties reflect true cell performance rather than measurement artifacts.

Designed primarily for advanced lithium-ion and solid-state pouch cell development, this testing unit serves research institutes, university laboratories, and industrial gigafactory quality control lines. It accommodates a broad range of pouch cell tab dimensions and configurations, facilitating high-rate discharge testing, electrochemical impedance spectroscopy (EIS), thermal runaway characterization, and continuous lifetime cycling across varied ambient environments.

Built to withstand rigorous thermal and electrical stress, the system guarantees long-term operational integrity under continuous loads up to 100A and ambient temperatures up to 125°C. High-grade dielectric insulation combined with UL94 V-0 certified flame-retardant structural materials provides multi-layered protection against thermal and electrical faults, offering total testing confidence during high-power fast-charging and extreme environmental stress evaluations.

Key Features

• High-Current Handling Capacity: Rated for continuous operation up to 100A, the clamp accommodates demanding fast-charging protocols, high-rate C-rate capability testing, and dynamic pulse discharge evaluations without overheating or degrading contact surfaces.
• Ultra-Low Contact Resistance: Engineered with precision-finished conductive contact points to maintain contact resistance below 25mΩ, preventing localized I²R heating and eliminating measurement distortion during precision electrochemical testing.
• High-Temperature Thermal Resilience: Fully operational across environments up to 125°C, making the fixture ideal for environmental chamber testing, high-temperature calendar aging studies, and accelerated thermal degradation evaluations.
• Superior Dielectric Isolation: Delivers insulation resistance exceeding 1×10⁹ Ω at 500V DC between electrical pathways and the frame, preventing stray leakage currents and ensuring accurate low-current EIS or leakage measurements.
• Certified Flame Retardancy: Constructed with structural polymers meeting the stringent UL94 V-0 standard, providing self-extinguishing safety properties that mitigate fire propagation risks during extreme overcharge or thermal abuse tests.
• Uniform Pressure Distribution: Features an engineered clamping geometry that applies balanced, repeatable force across cell tabs, preventing tab crimping, localized strain, or intermittent contact during prolonged thermal cycling.
• Four-Wire Kelvin Connection Compatibility: Supports dedicated current-carrying and voltage-sensing pathways directly at the tab interface, completely canceling lead resistance for millivolt-accurate terminal voltage monitoring.
• Corrosion and Oxidation Resistance: Treated contact surfaces resist oxidation, electrolyte vapor exposure, and repeated mechanical insertions, ensuring stable electrical conductivity throughout thousands of test cycles.
