In today's rapidly developing new energy vehicle industry, range anxiety and charging efficiency remain core pain points affecting user experience. As an EV battery manufacturer committed to independent research and innovation, VREMT has launched the world's first mass-produced ultra-fast charging lithium iron phosphate (LFP) battery—the 800V battery pack. This 800V battery pack not only breaks the industry's energy efficiency ceiling but also redefines the recharging rules for electric vehicles with revolutionary technology.
The technological breakthrough of the VREMT 800V battery pack stems from a deep understanding of the energy efficiency bottlenecks in electric vehicles. According to the power formula P=UI and Joule's law Q=I²Rt, increasing voltage is the optimal solution for EV battery manufacturers to reduce losses and improve energy efficiency. By upgrading from a 400V platform to an 800V architecture, the VREMT 800V battery pack has achieved three core breakthroughs: significantly reducing the volume of wiring harnesses, greatly enhancing vehicle lightweighting; effectively reducing circuit losses, further improving energy usage efficiency; and achieving a leap in power density, laying a solid foundation for ultra-fast charging. This architectural innovation is not a simple parameter adjustment but a comprehensive optimization of materials, structure, and processes, creating a new technological ecosystem adapted to high-voltage scenarios.
In terms of performance, the 800V battery pack redefines the performance boundaries of EV batteries through four core technologies. The dual-rivet pole flow design enhances current-carrying capacity by 100% compared to traditional solutions, and the laminated multi-tab structure ensures uniform heat distribution under ultra-fast charging conditions. The extreme pulse discharge capability reaches 16C in 3 seconds, supporting high-performance models to achieve 0-100 km/h acceleration in 3 seconds, with no decay in mid-to-late acceleration. Test data shows that the battery pack's maximum charging rate is 4.5C, capable of replenishing over 1000 kilometers of range in 15 minutes, and charging speed in -10°C low temperatures is at least 25% faster than similar products.
To address the safety challenges of high-voltage platforms, the VREMT 800V battery pack adopts the world's most stringent safety standards, pioneering three extreme testing systems. The overpressure puncture test subjects fully charged cells to 150kN pressure (far exceeding the national standard of 100kN), with no leakage or power loss after 1 hour of rest following a deformation of over 30%. A 5mm steel needle penetration test results in a maximum surface temperature of only 33.0°C. In the fire test, the burning time reached 240 seconds, far exceeding the international standard of 130 seconds, with cell voltage and insulation performance remaining normal throughout. In the devil serial challenge, the battery pack underwent water immersion, fire, freezing, dragging, crushing, and high-drop tests, yet it did not catch fire or explode.
In terms of range, the VREMT 800V battery pack overcomes the industry challenge of low energy density in LFP batteries through structural innovation and material upgrades. This is achieved through a "compact sandwich structure," integrated liquid-cooled tray, and aerospace ultra-thin thermal insulation material design, achieving a volume utilization rate of 83.7%. Test data shows that the battery pack's mass energy density is 10% higher than traditional ternary lithium batteries, achieving range capabilities 800V battery packs comparable to ternary lithium while maintaining the inherent safety advantages of LFP chemistry.
Behind the technological implementation is strong manufacturing capability support, with the Quzhou Extreme Electric Factory being key to the success of VREMT's high discharge rate batteries. The Quzhou Extreme Electric Factory, the world's largest intelligent manufacturing base for three-electric and energy storage systems, covers 1567 acres and integrates R&D, production, and testing. Its core processes include dual-pump coupled electrode technology, self-developed cell stacking algorithms, and full-process AI quality inspection, ensuring over 200 tests throughout the production process, achieving industry-leading quality consistency.
The birth of VREMT's high discharge rate battery is not only a milestone in EV battery technology but also a new starting point for the energy replenishment revolution in new energy vehicles. As the world's first mass-produced ultra-fast charging LFP battery, it offers core advantages of "fast charging, long range, and greater safety," providing high-performance power solutions for global automakers. With the popularization of the 800V platform, the "range anxiety" of electric vehicles will eventually become history. As an outstanding representative of technological innovation among EV battery manufacturers, VREMT will continue to drive the industry towards a future of higher energy efficiency, greater safety, and more convenience.
