on september 22, the 2024 taizhou international automobile industry expo came to a successful conclusion. this exhibition was the first exhibition after the completion of taizhou national expo center. geely holding group participated with all its brands and exhibited all categories. as an important layout of geely in the field of new energy vehicles, weirui made a full coverage of its three-electric core products, and with its comprehensive strength of "one step ahead", it made an important contribution to the rapid development of the new energy vehicle industry.

the full range of 800v core three-electric products was unveiled, and the second-generation brics set a new global record

during the exhibition, weirui focused on displaying its 800v second-generation bric battery, 800v high-performance sic four-motor distributed electric drive, 800a ultra-fast liquid-cooled charging pile-hpc-v3, liquid-cooled super charging platform-gpc-g1 and other core products, fully demonstrating the "global 800v three-electric system solution" and the industry-leading diversified technology routes and global self-developed and self-produced capabilities. in particular, weirui's second-generation 800v ultra-fast charging bric battery uses the original "lithium-ion full-range acceleration technology" and has a maximum charging rate of 5.5c. it only takes 10.5 minutes to charge from 10% to 80% soc. for the first time, the lfp battery charging speed exceeds all currently mass-produced ternary lithium batteries, and has become the world's fastest mass-produced power battery.

in terms of intelligence, the bric ii uses the world's first car-cloud integrated ai bms battery management technology. through real-time analysis and calculation of a large cloud model, the accuracy of battery power estimation is improved by 33%, and the endurance accuracy is optimized by more than 37%. at the same time, through machine learning and multi-feature fusion algorithms, risky vehicles can be identified in advance, with an early warning coverage rate of more than 98%. the accuracy of health monitoring of the battery throughout its life cycle can also be improved by more than 25%, and the battery life can be extended by guiding the user's habits to use the power battery in a more reasonable way.

at the same time, the electric drive and charging piles are also far ahead in performance. the maximum power of the varian 800v high-performance sic four-motor distributed electric drive is up to 930kw, and the maximum torque is 1280n·m, which easily helps the zeekr 001fr achieve 2.02s zero-to-hundred acceleration. it is the world's largest mass-produced four-motor distributed electric drive with the highest power and torque density. regarding charging piles, the varian extreme liquid cooling charging pile-hpc-v3 is the world's first charging pile to achieve an output current of 800a, and the charging efficiency is the highest in the world. there is also a high-power, high-intelligence, high-compatibility, and high-expandable liquid-cooled super charging platform-gpc-g1 that fully covers the conventional fast charging market.

not only leading in performance, but also in market performance

the most intuitive manifestation of leading product performance is the rapidly growing market share. in 2021, vmware's three-electric products based on the vast architecture will be mass-produced, helping new energy vehicle brands such as zeekr and smart become industry pioneers. in 2022, vmware's self-developed electric drive system ranked among the top ten in the domestic monthly installed capacity list for the first time, with a year-on-year growth rate of more than 500%. in 2023, vmware's core three-electric products ranked among the top ten in the installed capacity list. in the first half of the year's power battery pack and drive motor supporting supplier list announced by gasgoo, vmware is the only local company that has ranked among the two major lists at the same time.

in 2024, the installed capacity of weirui's three-electric products reached a new high. according to the installed capacity data of new energy passenger car electric drive systems in the first half of the year by ne times, weirui's electric drive system ranked seventh. at the same time, the ranking list of installed capacity of domestic lithium iron phosphate power battery companies in the first half of the year showed that quzhou jidian, one of weirui's production and manufacturing bases, has entered the top ten. it is worth mentioning that the bric battery produced by quzhou jidian was released in december 2023, which truly achieved the goal of increasing volume as soon as it was launched. zeekr also stated that among the user groups of zeekr 007, 66% chose lithium iron phosphate bric batteries. this proportion fully proves the wide recognition of bric batteries by users.

in addition, v-trek's three-electric products are also widely used in models of multiple brands such as lotus, polestar, volvo, smart, lynk & co, geely galaxy, and geometry, simultaneously contributing to the high-quality development of the new energy vehicle industry.

self-developed and self-produced products are the basis for being one step ahead of others

as early as decades ago, weirui began to develop independent research and development of new energy vehicle power batteries. so far, it has submitted more than 1,200 patents in technology research and development, design application, process manufacturing, and trial production, including nearly 700 invention patents, covering core technologies such as battery cells, modules, pack, bms, motor and electronic control, and energy storage products, and has carried out international patent layout in stages. at the same time, it is understood that weirui has four major production bases in ningbo, quzhou, hangzhou, and zaozhuang, with a total area of ​​more than 2,000 acres, covering battery cells, batteries, electric drives, charging, energy storage and other related fields, forming a comprehensive new energy ecological chain.

the four major bases further enable the layout of the entire industrial chain to achieve efficient production through comprehensive intelligence and improve delivery quality. among them, weirui quzhou jidian factory, which produces brics batteries, is the first "smart manufacturing level 4 maturity factory" in zhejiang province, and the first smart manufacturing maturity level 4 factory in the national battery industry. it uses 5g+ industrial internet as a carrier, deeply integrates big data, ai, digital twins and other advanced technologies, and builds an industry-leading smart manufacturing management system. the automation rate of the battery factory's operating procedures is 100%, and a single line can produce one battery cell every 2.5 seconds, that is, each production line can produce 24 batteries in 1 minute. among the same type of products, the production efficiency ranks first in the industry. the comprehensive automation rate of the battery factory's production lines reaches 85%, and the single-line production efficiency reaches 46ppm, that is, each production line can process 46 batteries in 1 minute, which is also the highest efficiency in the same type of battery industry.

800v three-electric core products were collectively unveiled, and the self-developed and self-produced products set a global benchmark. at this year's taizhou international automobile industry expo, vmware once again demonstrated its full-link advantages in the core three-electric field, constantly breaking global records with its innovative strength, continuously helping auto brands win the decisive battle of new energy transformation, and helping the taizhou government accelerate the strategic process of "building a future automotive industry chain."
