Fujian Nebula Electronics Co., Ltd. (Nebula) is proud to announce that its independently developed 5V300A Cell Cycle Test System has successfully upgraded from ETL certification to the more authoritative UL certification. This milestone not only highlights the system’s continuous optimization in electrical safety, mechanical design, and environmental adaptability but also marks a significant breakthrough in meeting the highest international safety standards. This achievement provides Nebula with a stronger “passport” to access North American and global high-end markets.
From ETL to UL: Elevating Safety and Market Competitiveness
The Nebula 5V300A Cell Cycle Test System obtained ETL certification as early as 2023. This certification involved rigorous laboratory testing combined with factory quality system audits, validating that the system meets the stringent safety requirements of the North American market. ETL certification has long been recognized as a solid benchmark for safety and compliance, ensuring customer confidence in the fundamental quality of the product.
UL certification, represents a step above, with more stringent independent testing standards and broader global recognition. Highly respected in the North American premium market and major engineering projects, UL certification affirms not only compliance with fundamental safety norms but also adherence to the industry’s most rigorous safety evaluation frameworks.
Upgrading from ETL to UL certification reflects Nebula’s commitment to continually surpass product quality standards. It strengthens the company’s position in international high-end markets and enables Nebula to offer battery manufacturers, OEMs, and other downstream clients advanced testing solutions that meet global premium standards. This empowers customers to enhance product safety and reliability while boosting competitiveness and international recognition.
Performance Excellence and Advanced Features of the 5V300A Test System
The Nebula 5V300A Cell Cycle Test System delivers outstanding comprehensive performance across multiple critical stages, including battery R&D, production line testing, and quality verification. It supports high-power, high-energy secondary batteries such as consumer batteries, power batteries, energy storage batteries, and next-generation battery technologies like solid-state batteries.
Key technical highlights include:
Ultra-fast current rise (2ms) and driving profile simulation (10ms), accurately replicating rapidly changing load environments to capture dynamic battery performance with high precision.
Intelligent multi-range current scaling with an accuracy of up to 0.03% F.S., providing a reliable data foundation for battery performance optimization.
Modular design allowing a single channel current range of ±300A and up to 16 channels in parallel expansion (maximum 4800A), delivering scalable and flexible test configurations.
Seamless integration with external devices such as thermocouples, NTC sensors, pressure collectors, and auxiliary voltage measurement, enabling the construction of comprehensive, efficient cell test benches for a stable and reliable user experience.
Global Presence and Commitment to Innovation
The upgrade from ETL to UL certification is more than a symbol of enhanced compliance—it embodies Nebula’s deep dedication to product quality and international standards. To better serve its global clientele, Nebula has established an overseas subsidiary in North America, leveraging a localized sales and service network to swiftly address regional market requirements. This enables Nebula to provide end-to-end solutions, from technical consultation and customized system design to delivery and after-sales support.
Looking ahead, Nebula will continue to deepen its technological innovation in lithium battery testing, developing more advanced test systems that align with global safety standards and customer needs. By doing so, Nebula aims to accelerate the technological upgrade and sustainable development of the global new energy industry.
