Prismatic Battery Fixture for Same Side Terminals High Current Cell Testing

Product Overview

This high-current testing system is engineered specifically to accommodate prismatic lithium-ion, sodium-ion, and solid-state battery cells configured with same-side top terminals. Designed to deliver superior electrical contact stability and mechanical integrity, the fixture supports demanding charge-discharge cycling protocols up to 300A. Its modular architecture integrates an eight-channel testing rack with independent test units, enabling battery research laboratories and quality assurance facilities to streamline cell characterization while eliminating contact resistance inconsistencies.

Optimized for high-throughput laboratory validation, pilot-line formation, capacity grading, and pack-level module pre-sorting, this testing platform accommodates a versatile range of cell form factors. The adjustable clamp mechanism effortlessly handles cell lengths from 80 mm to 250 mm, cell thicknesses (widths) from 15 mm to 87 mm, and cell heights from 30 mm to 245 mm. Whether evaluating large-format energy storage cells or high-rate electric vehicle battery prototypes, the equipment ensures reproducible electrical performance across every testing cycle.

Constructed with heavy-duty structural framing and premium copper contact interfaces, this fixture guarantees exceptional thermal dissipation, mechanical rigidity, and corrosion resistance. By integrating high-spec M103-12-Y-300A contact probes with M16 terminal lug interfaces, the unit minimizes voltage drop and localized heating at critical connection interfaces. Laboratories can operate continuous, multi-shift testing campaigns with complete confidence in structural durability, worker safety, and measurement precision.

Key Features

• High-Current 300A Continuous Capability: Built with heavy-gauge conductive pathways and dedicated M103-12-Y-300A high-ampacity probes to support rigorous fast-charging, continuous high-rate discharging, and dynamic pulse characterization up to 300A without overheating.
• Precision Same-Side Terminal Compatibility: Specifically engineered contact assemblies accommodate prismatic cell designs where positive and negative poles are situated on the same side, providing adjustable terminal spacing between 70 mm and 146 mm for diverse cell designs.
• Broad Dimensional Adjustability: Fully adjustable clamping fixtures securely hold prismatic cells spanning 80–250 mm in length, 15–87 mm in thickness, and 30–245 mm in height, allowing seamless adaptation across diverse cell chemistries and casing designs.
• Optimized 8-Channel Space-Saving Architecture: Configured in a two-tier, single-sided rack layout with four testing channels per tier, maximizing laboratory floor efficiency while maintaining clear visual line-of-sight and unobstructed ergonomics for operators.
• Ultra-Low Resistance M16 Connection Ports: Standardized heavy-duty M16 wiring lugs ensure secure, low-impedance bolting to external cyclers, preventing parasitic resistance, connection loosening, and signal drift during prolonged cycling regimens.
• Independent Channel Modularity: Each test cell operates within a standardized module envelope measuring 250 mm × 278.5 mm × 555 mm, facilitating rapid channel servicing, individual cell loading, and effortless isolation without disrupting adjacent channels.
• Superior Thermal & Mechanical Stability: Built with high-strength structural materials and heat-dissipating probe mountings that withstand cyclic clamping pressures and elevated ambient testing temperatures without mechanical distortion.
