“A 5-minute charge for 2 hours of high-speed driving” may sound like a fantasy, but at the VREMT factory, this goal has become a reality. Since the launch of the “Golden Brick Gen 2” battery, its superior performance and innovative technology have garnered widespread attention among battery pack manufacturers. As an EV battery manufacturer, VREMT’s “Golden Brick Gen 2” battery is renowned not only for its ultra-fast charging speed but also for achieving multiple technological breakthroughs in safety and energy density.
Recently, Dongxiao, a reporter from Guancha Syndicate, visited VREMT’s Ji Dian San Dian Smart Manufacturing Factory in Quzhou. Together with its engineer Lin Weifang, they toured the production processes of the electric drive factory and battery factory, unveiling the secrets behind the “Golden Brick Gen 2” battery.
“Golden Brick Gen 2” Battery: The Fastest Mass-Produced Power Battery in the world
The charging time of new energy vehicles is a crucial aspect of user experience and key to avoiding range anxiety.
VREMT’s “Golden Brick Gen 2” battery, surpassing traditional ternary lithium batteries, has achieved a breakthrough in charging speed for EV battery manufacturers, becoming the world’s fastest charging mass-produced power battery. Its maximum charging rate reaches an astonishing 5.5C, requiring only 10.5 minutes to charge from 10-80% SOC, effectively addressing the core charging issue of new energy vehicles, completely liberating the user experience and eliminating range anxiety.
Unveiling the Secret to Speed: Pioneering Innovation
The breakthrough in charging speed of the “Golden Brick Gen 2” battery is a proof for VREMT’s commitment to innovation as a battery pack manufacturer. Lin Weifang explained that this technological breakthrough is attributed to two core innovations: revolutionary hardware cell materials and intelligent optimization of the battery management system.
In terms of battery materials, VREMT has enhanced the fast-charging potential of the “Golden Brick Gen 2” battery through multiple optimizations of the electrolyte, anode and cathode materials. For the optimization of anode and cathode materials, VREMT selected supercapacitor materials and ultra-fast charging graphite anode designs, enabling more efficient energy transmission and further optimizing charging performance.
In the management system, VREMT has empowered the Golden Brick battery with AI. The innovative cloud-integrated AIBMS technology can precisely monitor the battery’s real-time status and dynamically adjust the charging power. To meet users’ needs in extreme conditions, AI BMS also provides excellent thermal management strategies, ensuring performance while extending the battery’s lifespan.
Safety Measures Behind Fast Charging
While pursuing ultimate charging speed, VREMT also prioritizes the safety of its batteries. Through multiple protective measures and rigorous testing, users are ensured comprehensive safety while enjoying the convenience of fast charging.
According to Lin Weifang, to address the heat generated during fast charging, VREMT pioneered “eight thermal safety protection technologies” among EV battery manufacturers, keeping the battery temperature within a safe range. Additionally, during the production and development process of the Golden Brick battery, it underwent 220 system-level tests and 682 component tests, simulating various potential usage scenarios and extreme conditions to ensure outstanding performance in actual applications.
In the interview, Lin Weifang stated that self-developed cell technology is a significant advantage of the “Golden Brick Gen 2” battery, with its core components now fully localized, growing alongside China’s new energy supply chain. Regarding the industry’s “internal competition,” Lin believes that healthy competition should focus on product and technological innovation, bringing more possibilities to industry development.Against the background of increasingly fierce global competition in the electric vehicle industry, the development of VREMT’s “Golden Brick Gen 2” battery not only exemplifies VREMT’s “smart manufacturing” capabilities but also endows domestic new energy vehicles with further competitiveness. As the new energy market continues to expand, VREMT, as a leading EV battery manufacturer, is actively advancing technological innovation and full-chain collaboration, pushing the battery industry to new heights and aiding the ascent of China’s automotive industry.
