GSL Energy R Series Energy Storage Battery Obtains UL 9540A and UL 1973 Certifications, Achieving Strictest International Safety Standards

Recently, the GSL Energy R60 series energy storage battery successfully obtained two internationally authoritative safety certifications—UL 9540A and UL 1973. The entire testing and certification evaluation process was completed by SGS, an internationally renowned testing, inspection, and certification organization. This achievement marks GSL Energy's attainment of internationally leading levels in energy storage battery safety technology, system risk control, and global compliance capabilities, laying a solid foundation for the product's full entry into the North American market and other high-standard global markets.

The acceleration of global energy transition toward cleaner, distributed, and intelligent energy structures drives the safety performance of energy storage systems as the core bottom line for industry development. GSL Energy has consistently embedded the "safety gene" throughout the entire process of product R&D, system design, and manufacturing. From its initial design, the R series has been fully benchmarked against the world's highest safety standards.

UL 1973: Mandatory Safety Access Standard for Battery Energy Storage Systems in the North American Market

UL 1973 is a core safety certification standard for battery energy storage systems, covering multi-dimensional tests such as electrical safety, mechanical safety, environmental adaptability, and system functional safety. It is a critical entry threshold for battery products entering the North American market. Obtaining this certification signifies that the GSL Energy R series meets stringent international requirements in structural design, electrical protection, material reliability, and system safety control.

UL 9540A: Authoritative Standard for Evaluating Thermal Runaway and Fire Spread in Energy Storage Systems

UL 9540A is currently the most authoritative global standard for evaluating thermal runaway and fire spread risks in battery energy storage systems. The testing covers four levels—cell, module, unit, and installation—with a focus on assessing:

Conditions triggering thermal runaway

Fire spread pathways

Structural protection capabilities

System-level risk control capabilities

This certification has been adopted by numerous fire safety and regulatory agencies across North America, becoming an important reference for the safety design of energy storage systems. The GSL Energy R series' successful completion of this rigorous test fully validates its safety protection capabilities and system stability under extreme operating conditions.

SGS Full-Process Testing and Verification: Building Global Compliance Capabilities

During the certification process, SGS provided GSL Energy with comprehensive support, ranging from standard interpretation and product structure evaluation to testing verification and compliance guidance. In addition to UL 9540A and UL 1973, the R series has also obtained multiple international certifications, including IEC 62619 and CE, fully meeting the market access requirements of different countries and regions.

Driving Product Development with the World's Strictest Safety Standards

GSL Energy CEO Deng Yongjing stated:

"The acquisition of UL 9540A and UL 1973 dual certifications is a significant milestone in GSL Energy's globalization strategy. From the very beginning of its R&D, the GSL Energy R series has prioritized safety as its core genetic foundation. The successful completion of these dual certifications not only validates our technological strength in the field of battery safety but also secures the 'passport' for our products to enter the North American market. In the future, GSL Energy will continue to drive technological innovation based on the world's strictest safety standards, maintain strategic cooperation with SGS, and provide global customers with high-safety, long-life, and intelligent energy storage solutions, contributing to the global green energy transition."
