Industry: Consumer Electronics Development & Manufacturing

Application: Accelerating Performance and Safety Testing for a Diverse Range of Next-Generation Portable Devices

The consumer electronics industry thrives on rapid innovation, driving demand for more powerful, compact, and longer-lasting devices. From laptops and tablets to smart assistants, power tools, and personal mobility devices, battery technology is at the heart of this evolution.To meet the growing variety of power and design requirements, R&D and quality teams are testing an expanding range of cylindrical Li-ion cells, including 18650, 21700, 26650, 4680 and more formats to be discovered. 

Traditionally, each cell size required its own dedicated fixture—leading to longer setup times, increased equipment costs, and crowded workspaces. Ensuring reliable electrical contact across formats further complicated testing, risking inconsistent data and delays in product validation.

The AES Solution

Associated Environmental Systems (AES) addresses these challenges head-on with our innovative Universal Cylindrical Cell Holders. Designed for maximum versatility and ease of use, these 100 amp holders empower consumer electronics companies to streamline their battery testing protocols, from initial R&D to ongoing quality control.

Key benefits and features of the AES Universal Cylindrical Cell Holders include:

  • Unmatched Versatility: A single holder solution that effortlessly adjusts to accommodate a wide array of cylindrical cell sizes, including 18650, 21700, 26650, 4680, and more. This eliminates the need for numerous holders to accommodate a range of sizes, simplifying test setups.

  • Rapid & Easy Adjustments: The intuitive design allows for quick and tool-less adjustments to securely fit different cell diameters and lengths, significantly reducing the time spent reconfiguring test stations.

  • Optimized for Efficiency: Facilitates swift cell insertion and removal, enabling engineers and technicians to conduct more tests in less time and accelerate product development cycles.

  • Reliable, High-Quality Connections: Engineered to provide consistent, low-resistance electrical contact, ensuring accurate and repeatable measurement data critical for evaluating cell performance, cycle life, and safety.

  • Space and Cost Savings: By replacing multiple dedicated holders with one adaptable unit, labs can free up valuable bench space and reduce capital expenditure on testing accessories.

  • Seamless Integration: Our fixtures are designed to be easily integrated with various battery cyclers,  and our environmental chambers, providing a flexible solution for diverse testing environments
