Pouch Cell Aluminum Laminated Film Short Circuit Tester Battery Testing Equipment

Product Overview

This high-throughput inspection system is specialized quality control equipment designed for the advanced lithium-ion pouch cell manufacturing and research sectors. Engineered to perform non-destructive insulation and insulation breakdown verification, the instrument identifies internal and external electrical faults immediately following pouch vacuum pre-sealing or final edge-sealing, prior to electrolyte injection. By inspecting critical interfaces before electrolyte wetting, this testing unit effectively prevents defective, short-circuited cells from progressing further into the fabrication line, safeguarding chemical purity and overall manufacturing yields.

Built for high-volume automated production environments as well as pilot-scale battery laboratories, the equipment delivers comprehensive multi-point electrical insulation checking. It isolates potential micro-shorts caused by burrs, misaligned separator films, or packaging layer puncture between positive tabs, negative tabs, and the conductive middle aluminum barrier layer of the laminated packaging film. Integrating this testing apparatus into cell assembly workflows ensures that only structurally and electrically sound cells advance to downstream high-value chemical processing steps.

Combining robust pneumatic mechanical fixturing with ultra-responsive electrical sensing circuitry, this battery testing instrument guarantees consistent contact pressure, repeatable test results, and superior throughput. The rigid benchtop footprint and ergonomic loading configuration enable seamless deployment across industrial mass-production facilities, pilot development plants, and high-standard academic and industrial research cleanrooms.

Key Features

• Comprehensive Three-Point Circuit Verification: Simultaneously evaluates electrical isolation across three key nodal points—positive tab, negative tab, and the outer aluminum-plastic laminated film—detecting tab-to-tab and tab-to-casing shorts in a single automated testing sequence.
• High-Throughput Production Integration: Delivers rapid testing cycles capable of achieving processing capacities exceeding 900 pieces per hour, dramatically minimizing quality control bottlenecks in continuous cell assembly operations.
• Precision Micro-Adjustable Probing Assemblies: Outfitted with fully adjustable, wear-resistant gold-plated contact probes that accommodate varied electrode tab geometries, custom tab offsets, and diverse pouch casing dimensions with micro-millimeter precision.
• Pneumatic Actuation and Consistent Clamping: Operates with stable 0.4 to 0.8 MPa pneumatic pressure regulation to maintain uniform, repeatable clamping force across every cell specimen, preventing mechanical damage to delicate aluminum-plastic packaging.
• Wide Dimensional Compatibility: Designed to inspect a broad spectrum of pouch cell form factors, supporting cell lengths, widths, and thicknesses up to 150 x 80 x 12 mm with an adaptable layout handling overall footprints up to 150 x 150 mm.
• Industrial 24V DC Internal Architecture: Powered via single-phase AC 220V 50Hz input seamlessly stepped down to safe, low-noise 24V DC internal operating circuitry, maximizing operator safety while eliminating high-frequency test interference.
• Compact Benchtop Ergonomics: Built within a rigid 530 x 400 x 350 mm enclosure weighing only 30 kg, facilitating rapid deployment, cleanroom integration, and easy reconfiguration along battery assembly lines.
• Pre-Electrolyte Defect Prevention: Specifically engineered for pre-injection quality gating, eliminating the costly waste of chemical electrolytes, degassing resources, and formation cycles on structurally flawed cell assemblies.
