Blog Article
As "range anxiety" remains a constant concern for new energy users, "fast charging" becomes the key to solving this problem. In this technological race for high-voltage fast charging, VREMT's 800V battery pack, with its charging speed, safety standards, and world-leading integration efficiency, demonstrates solid power that breaks barriers. Transitioning from a 400V platform to 800V means reduced losses, higher power density, and a faster charging experience. The 800V is no longer just a concept on paper but an accessible reality.
800V becomes a new energy trend, redefining energy efficiency logic
Since the advent of electric cars, range anxiety and charging difficulties have always been major concerns for users. How to overcome the bottleneck of charging efficiency? As an EV battery manufacturer, VREMT offers a solution: transition from the 400V platform to the high-voltage 800V platform to achieve lower energy consumption and higher energy efficiency through higher voltage. According to electrical principles, power P=UI and loss Q=I²Rt, increasing the voltage allows for reduced current while maintaining the same power, thus reducing line losses and cable bundle volume, while increasing vehicle power density and energy efficiency. The launch of VREMT's 800V battery pack is a key practice to alleviate range anxiety and improve charging efficiency through technological advancements.
The world's fastest charging LFP battery, 15 minutes for a 1000 km range
As the world's first mass-produced ultra-fast charging lithium iron phosphate battery, VREMT's 800V battery pack has set numerous industry records, with a maximum charging rate of 4.5C, allowing for a range increase of over 1000 km in just 15 minutes, even in extremely cold environments like -10°C, far surpassing the charging speed of similar products. This is due to its unique dual guide pillar design, increasing overcurrent capacity by 100%, combined with a multi-tab overlapping structure, effectively controlling heat distribution during charging and achieving more efficient thermal management. Additionally, the use of full lithium ion acceleration technology significantly optimizes the release and reception efficiency of ions, making the high-voltage, high-current charging process more stable.
Solid safety standards, all "devil tests" passed
On the 800V high-voltage platform, safety standards face more severe challenges. The VREMT high discharge rate battery uses eight thermal protection technologies, effectively enhancing battery safety in new energy application scenarios. Among them, three extreme tests set new industry standards: a high-pressure puncture test of 150 kN with no leakage or power loss, with a surface temperature of only 33°C; a full burn test of 240 seconds, far exceeding the national standard of 130 seconds, with no fire or explosion; and a series of devil tests simulating extreme scenarios such as immersion, burning, freezing, dragging, crushing, and dropping, where VREMT's EV battery shows no signs of thermal failure.
The highest volume utilization rate in the world, range performance surpassing ternary lithium batteries
While pursuing safety and performance, VREMT Energy also optimizes volume and energy efficiency. VREMT's 800V battery pack adopts a compact "sandwich" structure, with a volume utilization rate of 83.7%, the highest in the world. Compared to traditional ternary lithium batteries, the overall energy density is increased by more than 10%. Among the improvements, the vertical space of the cell compartment is fully utilized; the integrated liquid cooling plate at the bottom brings a volume increase of 8.5%; and ultra-thin aerospace-grade thermal barrier materials effectively control thermal diffusion, ensuring every cubic centimeter of space is dedicated to performance.
The launch of VREMT's 800V battery pack is not only a leap forward in product power but also a signal of the evolution of the electric vehicle 800V battery pack fast-charging ecosystem. With the advent of the fast-charging era, VREMT, as an EV battery manufacturer, uses technological innovation to offer users a more efficient, safer, and more reliable charging experience, accelerating the global new energy industry into the era of "high-voltage ultra-fast charging."
