Full title and description

IEC/TS 62661-2-1:2013 — Technical specification providing test methods, measurement procedures and evaluation criteria for mechanical performance of tubular lithium-ion cells used in stationary applications, focusing on abuse and safety-related mechanical tests and sample preparation.

Abstract

This technical specification defines particular mechanical test procedures and requirements for tubular lithium-ion cells intended for stationary energy storage systems. It describes sample conditioning, test setups, test sequences (including compression, impact and vibration where applicable), measurement and evaluation criteria to assess mechanical integrity and safety performance under specified mechanical stresses. The document is intended to harmonize laboratory test methods to evaluate cell behavior and failure modes related to mechanical abuse.

Scope

IEC/TS 62661-2-1:2013 specifies mechanical test methods and evaluation criteria for tubular lithium-ion cells intended primarily for stationary applications (such as grid storage and backup power). The scope covers preparation of test samples, environmental conditioning, mechanical abuse tests relevant to installation and handling (for example compression and impact), measurement of electrical and physical responses, and criteria to classify unacceptable cell behavior, including leakage, rupture, fire or thermal runaway. It is aimed at providing repeatable laboratory procedures to assess mechanical robustness and safety performance rather than full system-level requirements.

Key topics and requirements

• Definition of test sample selection, pre-conditioning and state of charge for mechanical tests
• Procedures for mechanical abuse tests such as compression, flat plate crush, and impact
• Instrumentation and measurement requirements for monitoring voltage, temperature and physical deformation during tests
• Criteria for pass/fail evaluation including leakage, venting, fire, explosion and sustained thermal runaway
• Requirements for test environment, fixtures and safety precautions when performing destructive tests
• Reporting format and data to be recorded for reproducibility and comparison

Typical use and users

Primary users include battery manufacturers, test laboratories, certification bodies, and developers of stationary energy storage systems who need standardized mechanical test methods to assess cell-level safety and mechanical integrity. It is used during product development, safety validation, quality assurance and regulatory compliance activities where standardized mechanical abuse testing of tubular lithium-ion cells is required.

Related standards

Related documents and standards commonly used alongside this TS include the IEC 62660 series (performance and safety of lithium-ion cells for propulsion in electric road vehicles), IEC 62133 (safety requirements for portable sealed secondary cells and batteries), IEC 62619 (safety requirements for secondary lithium cells and batteries for industrial applications), and other parts of IEC 62661 series covering different test types and cell formats. National and regional battery safety regulations and UN transport tests for lithium batteries are also relevant when assessing overall compliance.
