As new energy technology sweeps through the construction machinery sector, safety performance has become the "Sword of Damocles" hanging over all industry players. Zoomlion, China's leading construction equipment manufacturer, has recently made a breakthrough by having its self-developed series of power batteries successfully pass all tests under the mandatory national standard GB38031-2025 "Safety Requirements for Power Batteries of Electric Vehicles." This achievement establishes a new safety benchmark for new energy construction machinery.
Meeting Stringent New Standards: Zoomlion's Technological Breakthrough
The upcoming GB38031-2025 standard, set to take effect on July 1, 2026, introduces unprecedented safety requirements for power batteries. The regulation includes particularly rigorous challenges in three key areas: thermal propagation testing, bottom impact testing, and fast-charge cycle testing.
Under the revised thermal propagation test, the observation period for thermal runaway has been extended from 5 minutes to 2 hours, with strict limitations on potential harm to occupants from smoke emissions. This demands significantly enhanced battery endurance in extreme conditions. The bottom impact test simulates road debris collisions, requiring batteries to maintain structural integrity with no leaks or casing fractures while meeting insulation resistance standards. Additionally, the new standard introduces a 300-cycle fast-charge durability test for batteries supporting 15-minute rapid charging, evaluating both longevity and stability under frequent fast-charging conditions.
Zoomlion's battery series demonstrated exceptional performance across all tests, showcasing advantages in longevity, safety, structural strength, and rapid charging capability. This achievement underscores the company's technological leadership in battery development.
Comprehensive Safety Management: Zoomlion's Integrated Approach
As an industry leader, Zoomlion has established a complete safety management system covering the entire production chain from core components (motors, batteries, and electronic controls) to system integration and complete machinery. This comprehensive approach not only enhances product reliability and competitiveness but also creates significant technological barriers to entry. The recent certification serves as tangible proof of Zoomlion's technical capabilities in battery safety.
The company's proprietary power batteries have already been deployed in numerous road and off-road vehicles, including pure electric mixers, high-power tractors, loaders, and mining trucks. Field applications have accumulated over one million kilometers of operation, validating the batteries' performance and reliability in real-world conditions.
Commitment to Carbon Neutrality: Zoomlion's Green Transition
Zoomlion has actively aligned with China's dual-carbon strategy, pursuing intelligent, digital, and green transformation. The company has completed the electrification of its full construction machinery product line and successfully developed electric agricultural equipment like tractors. Its core electrical components have also entered global markets alongside host machinery, contributing to the worldwide transition toward new energy solutions in construction equipment.
In the first half of 2024, Zoomlion introduced several landmark new energy products, including the world's first pure electric port tire crane, the first five-axle right-hand drive electric mixer, and a 100-ton hybrid off-road dump truck with wire-controlled chassis. These innovations have expanded Zoomlion's product portfolio while reinforcing its technological leadership in green construction machinery.
Industry Perspective: Leadership in Technological Innovation
Industry analysts note that leading manufacturers' in-house battery development enhances product reliability, creates competitive advantages, and establishes technological barriers. Such vertical integration also reduces lifecycle costs, secures supply chains, fosters innovation, and enables new business models. Zoomlion's achievements in battery technology are expected to significantly influence the broader construction machinery sector.
Looking ahead, Zoomlion plans to continue driving innovation through the integration of intelligent, digital, and green technologies, developing premium products that set industry standards. Through sustained technological advancement and product upgrades, the company aims to make substantial contributions to the global construction machinery industry's sustainable development.
