The Cylindrical Battery In-Situ Volume Swelling Testing System is designed for real-time measurement and analysis of volume and dimensional changes of cylindrical lithium-ion cells during charge and discharge processes. The system uses non-contact laser displacement technology to accurately capture micro-level swelling behavior under controlled temperature and pressure conditions. It provides reliable data support for safety evaluation, reliability testing, and structural optimization of cylindrical batteries.

Application

(1) In-situ volume swelling analysis of cylindrical lithium-ion batteries during cycling.

(2) Expansion behavior evaluation of 18650, 21700, and similar cylindrical cell formats.

(3) Safety and reliability assessment under fast charge, overcharge, and abuse conditions.

(4) Thermal-mechanical coupling analysis under elevated or low-temperature environments.

(5) Fatigue and pressure response testing during long-term cycling.

(6) R&D validation and quality comparison for different cell designs and materials.

Standards

(1) UL 1642 – Standard for Lithium Batteries.

(2) IEC 62660-2 – Secondary Lithium-Ion Cells for the Propulsion of Electric Road Vehicles – Reliability and Abuse Testing.

(3) ASTM E83 – Verification of Linear Displacement Measuring Systems.

(4) ISO 12417-1 – Mechanical Testing of Metals – Dilation Test (reference method).

(5) CE Certification – Conformité Européenne.

Features

(1) Sub-micron non-contact displacement measurement with laser-based sensors.

(2) High-resolution detection of radial and axial swelling during rapid cycling.

(3) Multi-environment testing with integrated temperature chamber.

(4) Dynamic pressure loading capability for fatigue and structural response testing.

(5) Four-channel parallel testing for improved efficiency and data consistency.

(6) Real-time volumetric strain visualization using structured light scanning.

(7) Automatic thermal drift compensation for long-term stability.

(8) Dual redundant safety protection with emergency stop system.
