IEC 62984-1:2020

Overview

IEC 62984-1:2020 is an international standard published by the International Electrotechnical Commission (IEC) that establishes the general requirements for high-temperature secondary batteries. These batteries are designed for both mobile and stationary applications with a nominal voltage up to 1,500 V. The standard specifically covers electrochemical battery systems with a minimum operating temperature above 100 °C. It excludes aircraft batteries, governed by IEC 60952, and batteries for electric road vehicle propulsion, regulated by IEC 61982.

This standard aims to provide manufacturers, designers, and users of high-temperature secondary batteries with a comprehensive framework including definitions, design requirements, environmental considerations, testing protocols, and safety markings. Ensuring compliance with IEC 62984-1:2020 aids in promoting battery safety, performance reliability, and interoperability in various high-temperature applications.

Key Topics

• Battery Definitions and Terminology: Provides clear definitions related to battery construction, functionality, symbols, and abbreviations specific to high-temperature secondary batteries.

• Environmental Conditions: Details normal and special service conditions for both stationary and mobile installations, including indoor and outdoor environments. This ensures batteries are designed for real-world conditions they will endure.

• Design and Mechanical Requirements: Covers battery architecture including modules, battery assembly, and thermal management subsystems. Mechanical robustness against vibration and impact is addressed along with enclosure protections.

• Electromagnetic Compatibility (EMC): Specifies EMC performance requirements to ensure batteries function properly without causing or suffering from electromagnetic disturbances.

• Testing Protocols: Classifies various tests including mechanical, environmental, EMC, routine, and special tests that batteries must undergo to verify compliance with the standard.

• Markings and Documentation: Defines data plate markings and necessary documentation like instruction manuals and test reports to ensure traceability and user guidance.

• Transportation, Installation, and Maintenance: Provides rules and recommendations for the safe handling of high-temperature secondary batteries throughout their lifecycle.

Applications

IEC 62984-1:2020 is essential for industries and sectors where high-temperature secondary batteries are utilized, including:

• Industrial Energy Storage: Batteries for backup power, grid stabilization, and load leveling where high-temperature tolerance enhances durability.

• Mobile Equipment Power Supplies: Batteries used in off-road vehicles, remote equipment, or mobile machinery that operate in harsh thermal environments.

• Stationary Power Systems: Energy storage for facilities operating in high ambient temperatures requiring reliable battery performance.

• Specialized Electronics and Instruments: Equipment that demands batteries capable of withstanding elevated operational temperatures without performance degradation.

By following this standard, manufacturers can design and produce batteries that meet robust safety and performance criteria, enabling reliable operation in challenging thermal environments and extending battery lifetime.
