Under the wave of reform of the global new energy vehicle industry, China’s power battery industry has established a leading position.
In addition to the well-known Ningde era, BYD, the two “leaders”, there are many enterprises are accumulating abruptly, strong breakthrough, Weirui is one of them.
This enterprise, which belongs to Geely holding Group, based on the new energy vehicle Sandian, has embarked on a new energy “smart” road that only belongs to our country.
Earlier, when the digital exhibition hall of the Weirui Quzhou factory was opened for the first time, Galaxy walked into the battery, battery and electric drive factory and felt the meaning behind “Weirui Smart Manufacturing, one step faster” at close range.
Weirui Quzhou factory digital exhibition hall, photo source: Weirui, it is reported that Weirui Quzhou factory has the most advanced intelligent manufacturing plant in the battery industry, producing star products “BRICS batteries”.
Behind the “one step faster”, there is the outbreak of Weirui’s accumulation of technology for more than a decade, as well as its deep insight into the market and the blessing of its “smart” skills.
Weirui’s products not only conform to the current development trend of the new energy industry, but also set a new benchmark for the “smart building” of the three new energy companies.
“one step faster”: it is not only the advantage, but also the backing.
Nowadays, the development of the new energy vehicle industry is “advancing by leaps and bounds”, and the “inner volume” is becoming more and more serious.
Among them, the “three electricity system”, as the core component of new energy vehicles, is not only related to the performance of the whole vehicle, but also one of the key factors affecting consumers’ choice and purchase.
Weirui is the core supplier of polar krypton brand new energy model “Sandian”.
It is reported that polar krypton has been announced in October, with a cumulative delivery of more than 350000 units in 35 months, creating a “record for the fastest new power of pure electricity.
” At the same time, Weirui’s own batteries and electric drives have been installed in many models such as polar krypton 001FR, polar krypton 007, polar krypton 7X, polar krypton MIX and so on.
It can be said that the rapid mass production of many extremely krypton models and the “remarkable” market performance are inseparable from the technology accumulation and stable supply of Weirui’s “three electricity system”.
Among them, the “BRICS battery” produced by Weirui Quzhou factory plays an even more important role.
It is reported that the second generation of BRICS battery continues the excellent performance of the previous generation in terms of charging rate, safety and intelligent management.
Under the condition of low temperature and low electricity, the state is more stable, which makes the performance of the whole vehicle more superior.
The digital exhibition hall of Weirui Quzhou factory, photo source: Weirui, in the ranking list of domestic lithium iron phosphate power battery enterprises from January to October 2024 released by the China Automotive Power Battery Industry Innovation Alliance, the lithium iron phosphate battery (BRICS) battery produced by Quzhou Electric Power Plant, one of the four major bases of Weirui, ranks among the top 10, accounting for 1.
51% of the market.
This is less than a year after the first generation of BRICS batteries went on sale in December 2023.
At present, Weirui has four major production bases in China: Quzhou, Hangzhou, Ningbo and Zaozhuang, among which “fast” is one of the distinctive features of Quzhou factory.
Zhang Tianzhi, deputy general manager of Quzhou Polar Power and general manager of Weirui Battery Division, who has experienced the construction of the Quzhou plant, said that the Quzhou factory has always maintained the advantage of “one step faster” because of its “quick completion, quick commissioning and fast production speed”.
It is reported that the Quzhou plant took only 17 months from opening to commissioning.
According to the current planning, the Quzhou plant has an annual production capacity of 48GWh cells, 840000 sets of new energy battery packs, 1.
21 million sets of electric drive and 17GWh energy storage system.
As a matter of fact, Weirui was established as early as 2013.
With more than ten years of technology research and development experience in the field of Sandian, Weirui has built a global leading R & D and verification system to achieve a global, full-scene technology layout.
At present, in addition to extreme krypton, Weirui’s self-developed products are also available in many brands such as Lutes, Polar Star, Volvo, smart, Lecker, Geely Galaxy, Geometry and other brands.
“smart” speed: every 2.
5 seconds offline a cell, with the full electrification acceleration coming, the power battery industry is about to enter the TWh era.
The arrival of a new round of scale expansion cycle not only puts forward higher requirements for manufacturing links, but also makes the demand for intelligent upgrading of lithium production and manufacturing more urgent.
Weirui Quzhou factory has also been steadily in the forefront in terms of “intelligent building”.
It is reported that the Weirui Quzhou factory covers a total area of 1567 mu and is by far the largest integrated intelligent manufacturing plant for three electricity and energy storage systems in the world.
it has the production and supply capacity of new energy power cell, battery pack, three-in-one electric drive system and energy storage system.
, Weirui Quzhou factory, photo source: Weirui, in September this year, Quzhou battery factory won the “CMMM level 4 standard certification” with high scores, becoming the first level 4 maturity factory in Zhejiang Province and the first factory in the national battery industry to win this award.
It is reported that CMMM is the compliance assessment of intelligent manufacturing capability maturity standards, is regarded as the most instructive industry compass in the domestic intelligent manufacturing field, and is the highest-level national certification in the domestic intelligent manufacturing field.
According to the person in charge of the production line, each production line in the cell factory has deployed 5000 + quality control points, equipped with 750 CCD intelligent detection cameras, 360 degrees without dead angle monitoring, and used the industry’s first “double-pump coupling technology” and “dual-optical control monitoring and feedback system”, which can be online real-time error correction and closed loop, all-round protection of cell quality.
The battery factory also applies the fully automatic die-cutting lamination technology to achieve a single lamination efficiency of 0.
15s, pole width size precision 0.
2mm, length size precision 0.
5mm, which not only improves battery safety, but also reduces comprehensive energy consumption.
At present, the battery factory has achieved 100% automation of the whole process, the cell production line efficiency is as high as 24 PPM, and one cell is offline every 2.
5 seconds, which is the first in the industry in the same type of products.

Old problem: with a new solution, “New energy is developing very fast in China, and it is crucial to find the right direction.
” If the strategy and direction are wrong, then efforts will not help.
” Zhang Tianzhi said bluntly, “only to comply with the development trend of the new energy automobile industry and solve the consumer customs.
“Only by the core issues of the heart can we develop better.
” This means that it is not enough to achieve “fast production speed”, but also to improve core competitiveness from a technical perspective.
At present, my country’s new energy vehicle industry has entered a period of comprehensive market expansion, but it still faces “old problems” such as energy replenishment anxiety and power battery safety.
With the support of “acceleration” and “intelligent manufacturing”, Weirui is seeking new solutions.
In order to alleviate the anxiety about replenishing new energy vehicles, Verui regards “fast charging” as a breakthrough point.
Through the lithium-ion full-process acceleration technology, the second generation BRICS battery has a maximum charging rate of 5.
5C, and a fast charging of 10%-80% can be completed in 10.
5 minutes.
This is the first time that the charging speed of lithium iron phosphate batteries has surpassed that of mass-produced ternary lithium.
It is also the fastest charging speed of mass-produced power batteries in the world.
, In order to improve the safety of power batteries, the second-generation BRICS battery adopts eight thermal safety protection technologies and continues the highest battery safety standards of the first-generation BRICS.
It has gone through battery overpressure needle punching tests, full-pack 240-second fire tests, and Six major extreme working conditions are tested serially to ensure the safety of batteries in various extreme environments.
At the same time, it also introduces AI BMS technology integrated into the vehicle cloud to analyze battery data in real time, formulate personalized management strategies, improve power estimation and battery life accuracy, and establish an accurate battery warning model.
According to Jikrypton, 66% of the users of Jikrypton 007 choose lithium iron phosphate BRICS batteries instead of ternary lithium batteries.
This proportion fully proves the widespread recognition of BRICS batteries by users.
, In addition, Verui also relies on its hard-core strength in the core three-electric field to help Gekrypton create “three 800 full ecological solutions”, namely a full-stack 800V car, an 800V power battery and an 800V compensation network.
This “moat” can provide users with the ultimate travel experience of “charging for 5 minutes and high-speed for two hours”.
