SHANGHAI, Dec. 5, 2024 /PRNewswire/ -- TÜV Rheinland Greater China, an international independent third-party testing, inspection, and certification organization, has issued Eye Comfort (5 Star), High Visibility, Color Accuracy, Low Blue Light, and Flicker Free certifications to the newest augmented reality (AR) glasses created by XREAL, the XREAL One Series. These achievements mark a groundbreaking advancement in AR eyewear, setting new benchmarks for user health and comfort.
TÜV Rheinland's star-rating system for Eye Comfort Certification evaluates AR glasses based on five dimensions: visual perception, visual health, ergonomics, human performance, and user guidance. A higher star rating signifies exceptional performance across these metrics.
A particular focus has been placed on human performance, with TÜV Rheinland establishing rigorous standards for near-eye optics and ergonomics. Tests simulated real-world scenarios to evaluate key aspects such as eye strain reduction, prolonged wear comfort, and binocular fusion accuracy.
In addition to certifying eye comfort, TÜV Rheinland conducted tests on screen content visibility under various indoor and outdoor conditions, covering maximum brightness, field of view, pixel density, contrast, transparency contrast, and geometric distortion. AR glasses that meet these standards are certified High Visibility performance, ensuring an enhanced and more comfortable viewing experience for users.
Zongkai Liu, Product Head of XREAL, states that "XREAL One Series is equipped with a custom silicon chip 'X1 Chip' designed specifically for optical see-through (OST) AR glasses, enabling spatial computing and meeting the high-performance demands of users. The One Series not only offers a wide field of view but also provides a more stable spatial screen with low-latency technology for consistent spatial display. We are thrilled that the One Series is the first to receive TÜV Rheinland's latest Eye Comfort (5 Star) and High Visibility Certificates, offering users immersive AR experiences without compromising their eye health."
Frank Holzmann, Global Senior Vice President of TÜV Rheinland Electrical, emphasizes the organization's commitment to advancing AR technology: "As AR glasses evolve with breakthroughs in optical design, interaction methods, and display technologies, TÜV Rheinland continues to lead in developing standards that prioritize user health and comfort. Our certifications provide manufacturers with a pathway to enhance product quality while offering consumers reliable, science-based purchasing guidance."

BEIJING, April 3, 2026 /PRNewswire/ -- HiTHIUM showcased its full-scenario energy storage solutions at ESIE 2026, held in Beijing from April 1-3. The company highlighted its ∞Cell 1175Ah long-duration energy storage (LDES) battery and BESS, along with its AIDC full-duration energy storage solution. At the event, HiTHIUM released the full results of a large-scale fire test for its ∞Power 6.25MWh 4h BESS and received certification from UL Solutions. This marks the world's first open-door fire test of the LDES system equipped with kAh-level battery cells, setting a new benchmark for system-level safety validation.
Advancing Industry-Wide Understanding of Energy Storage Safety
During the exhibition, HiTHIUM hosted a certification ceremony for the world's first large-scale fire test of a BESS equipped with kAh-level battery cells. Jiawu Chen, the Fire Test Project Lead and Senior Fire Protection Design Engineer at HiTHIUM, presented the test design and execution. A full-length video showcased the entire process, key technical milestones, and final results.
Through this technical sharing, HiTHIUM translated an extreme safety validation into practical and replicable industry insights, reinforcing the shift from "design-level safety" to verifiable system safety in long-duration energy storage.
UL Solutions Grants the Certification, Validating System Safety
During the certification ceremony, Chi Chen, APAC Senior Product Manager, Energy and Automation at UL Solutions, noted that UL 9540A 6th Edition (released March 2026) expands safety validation to full-container and system-level fire scenarios. HiTHIUM's 6.25MWh BESS was tested under open-door, large-scale fire conditions in compliance with this standard, validating the reliability of its passive safety design.
The certification indicates the system meets stringent market access requirements across major global markets and supports its international deployment.
Verifiable Safety Demonstrated in World's First Extreme Fire Test of a 6.25MWh 4h LDES System
Previously, under the full witness of UL Solutions and independent experts, the 6.25MWh BESS underwent an extreme fire test in accordance with the latest UL 9540A (2025) and NFPA 855 (2026) standards. The test applied multiple stringent conditions, including fully open container doors, minimal spacing of 15 cm in a back-to-back and side-by-side configuration, 100% state of charge, and deactivation of active fire protection systems.
Results showed the fire was contained within a single container, with no thermal propagation between units. The enclosure remained structurally intact after the burn, demonstrating reliable safety performance under real-world fire scenarios.
Ecosystem Collaboration Highlights Lighthouse Manufacturing
At the exhibition, HiTHIUM partnered with ecosystem collaborators to launch interactive check-in activities centered on the ∞Cell 1175Ah LDES battery, featuring a joint partner booth tour and a lighthouse factory-themed experience, attracting strong visitor engagement and in-depth interaction.
Notably, in January 2026, HiTHIUM's Chongqing manufacturing base was recognized as the world's first Lighthouse Factory for energy storage batteries and operates the first dedicated production line for LDES batteries. The site integrates over 40 digital solutions, incorporating technologies such as generative AI, machine learning, and AIoT to enable end-to-end intelligent management—from R&D and material selection to manufacturing and final testing—ensuring high consistency across production.
Looking ahead, HiTHIUM will continue to focus on long-duration energy storage, strengthening its capabilities in verifiable product safety, scalable delivery, and full-scenario solutions. Together with global partners, the company aims to support the high-quality development of the energy storage industry and advance the global energy transition.
