Quzhou, December 14, 2023 – Today, ZEEKR Intelligent Technology officially released the world's first mass-produced 800V lithium iron phosphate ultra-fast charging battery - Golden Brick Battery. The volume utilization rate of the gold brick battery is 837%, which is currently the world's highest volume utilization rate of power batteries, the world's fastest mass production charging speed of 800V lithium iron phosphate batteries, and the world's safest power batteries, will fully lead the 800V era in terms of safety, experience and cost. It is worth mentioning that the production efficiency of BRICS batteries has been increased by more than 40%, and compared with ternary lithium batteries with the same performance, BRICS batteries can be reduced by 14 per kilowatt-hour8% of the cost. At present, the gold brick battery has been officially mass-produced and rolled off the assembly line, and will be equipped on the ZEEKR 007 for the first time.
At a time when the market share of new energy vehicles has exceeded one-third, battery life and energy replenishment anxiety are still the pain points restricting the development of the industry. As a technology-driven technology company, ZEEKR focuses on the core technology in the key areas of new energy vehicles, leads industry innovation, and brings users a more extreme battery life and energy replenishment experience. As the latest achievement of ZEEKR's comprehensive self-research in the core three-electric field, the golden brick battery breaks the limitations of traditional lithium iron phosphate batteries: the battery capacity is low, the charging speed is slow, and the test is not afraid of piercing, hitting the road or burning, allowing users to completely bid farewell to range anxiety and safety anxiety, and bring a more luxurious, safer and smarter travel experience.
Traditional lithium iron phosphate batteries represent high safety and high cost performance, but the key energy density is not comparable to ternary lithium batteries. ZEEKR subverts the tradition and makes technological breakthroughs to "turn stones into gold", and the volume utilization rate of the gold brick battery has reached 837%, surpassing all lithium iron phosphate batteries, and surpassing the current leading ternary lithium batteries.
In order to be able to place more battery cells in the battery pack, the ZEEKR engineering team has completely transformed the battery pack structure: an integrated liquid-cooled tray is used at the bottom of the battery to replace the traditional water pipe structure to reduce the squeeze of the cell space by structural partsThe "compact sandwich structure" of the cell, upper cover and bottom plate is adopted to release the longitudinal space of the cell compartmentAviation-grade ultra-thin thermal barrier materials are used between battery cells to fully improve the volume utilization rate. Compared with the traditional design, the total length of the sampling line of the BRICS battery is also shortened by 157 m, the number of core components is reduced by 35%, and the energy density of the battery mass is also increased by more than 10%.
Even if the new energy vehicle has achieved thousands of miles of battery life, the owner's range anxiety still cannot be effectively alleviated, in the final analysis, it is still caused by the long charging time and the lack of convenience and speed of the energy replenishment experience. Ordinary lithium iron phosphate batteries, even in the fast charging range of 30%-80%, the charging time still takes more than 30 minutes.
More efficient energy replenishment requires the two-way evolution of high battery charging rate and ultra-fast charging and charging facilities. Thanks to the self-developed global 800V architecture and matching 800V extreme charging technology, the maximum charging power of the BRICS battery can reach 500 kW, and the maximum charging rate reaches 45c；In the 10% and 80% fast charging range, the battery life of 15 minutes of charging can be increased by more than 500 km, becoming the world's fastest mass-produced lithium iron phosphate battery, allowing users to enjoy the ultimate experience of "traveling thousands of miles in one moment".
