VREMT 800V Battery Pack: Precisely Overcoming LFP Energy Density Challenges, Extending Range Further
Blog Article
In the electric vehicle sector, the energy density of EV batteries is one of the core standards for assessing their performance, directly affecting the range and user experience of electric vehicles. Lithium iron phosphate (LFP) batteries are known for their safety, longevity, and low cost, but they suffer from low energy density, limiting their presence in the high-end electric vehicle market. Addressing this challenge, the VREMT 800V LFP battery has achieved a breakthrough in overcoming the energy density bottleneck of LFP battery modules through revolutionary innovation. By advancing both materials and structure, it has not only increased the volume utilization rate of battery modules to 83.7% but also achieved significant improvements in battery safety and range, setting a new benchmark for the global electric vehicle industry.
From a structural design perspective, the VREMT 800V LFP battery module employs a compact "sandwich structure." The cells, top cover, and bottom plate are ingeniously designed to form a tightly connected whole. This design not only frees up longitudinal space in the cell compartment, allowing for a matrix arrangement of cells, but also significantly increases volume utilization by 7.6%. More importantly, the compact structural layout strengthens the connection between the cells and the top cover and bottom plate, effectively reducing vibration and impact, thereby enhancing the structural stability of the VREMT 800V battery pack and providing solid assurance for the safe operation of electric vehicles.
In terms of the cooling system, the VREMT 800V LFP battery also demonstrates extraordinary innovation. Traditional liquid-cooled battery cooling systems often require complex piping to transfer coolant, which not only occupies valuable battery module space but also increases system complexity and maintenance costs. VREMT's integrated liquid-cooled tray structure incorporates the cooling function into a single structure, greatly freeing up internal space within the battery module, further increasing volume utilization by 8.5%, achieving more efficient and uniform heat PHEV solutions conduction, and effectively extending the lifespan of the dual-sided liquid-cooled battery.
Additionally, the VREMT 800V LFP battery features a unique "T" shaped sampling and control design. This design shifts the traditional sampling and flow space from the Z direction to the Y direction, achieving shared space with the cross and longitudinal beams, further enhancing space utilization. Compared to traditional designs, the total length of sampling lines in the VREMT 800V battery pack is reduced by 157 meters, the total number of components is reduced by 60%, and the mass energy density of the EV battery is increased by more than 10%. This innovative design simplifies the structure of the strong thermal management battery pack, reduces costs, and significantly enhances the overall performance of the liquid-cooled battery.
In summary, the VREMT 800V LFP battery, through dual innovations in materials and structure, successfully overcomes the energy density limitations of LFP batteries, achieving dual enhancements in EV battery safety and range. Not only does it lead globally, but it also brings new breakthroughs in the range of electric vehicles. With continuous technological advancements and a maturing market, the VREMT 800V LFP battery is poised to lead the electric vehicle industry into a greener, more efficient, and safer new era.
