Recently, the first batch of 10 split-type super charging stations, exclusively customized by our company for our clients, has successfully completed production, passed rigorous inspections, and been shipped. As an innovative achievement in new energy vehicle (NEV) charging infrastructure, these products embody a "zero-defect" quality management philosophy throughout the entire process from R&D to delivery. Supported by digitalized and lean control systems, this project establishes a new benchmark for quality control in high-end customized charging equipment.  

Comprehensive Quality Control: From Sub-Millimeter Precision to National Standards

In terms of quality assurance, we implemented a triple-layered safeguard system covering raw materials, manufacturing processes, and testing. First, core components were sourced from BYD-certified suppliers, with all electrical elements complying with UL, CE, and other international certifications. Additionally, 20 customized inspection criteria were introduced to address the structural specifics of the split-type design. Second, a dual-quality inspection protocol was enforced during production, integrating AI vision systems at critical stages to ensure assembly precision within ±0.05mm. Finally, finished products underwent over 200 quality tests, including a 72-hour continuous aging test, IP68-rated waterproof and dustproof validation, and extreme temperature tests ranging from -30°C to 55°C, guaranteeing lifecycle reliability.  

End-to-End Process Control: Digitalization Drives Intelligent Manufacturing  

For process management, the project team adopted a transparent "end-to-end" digital governance model. By deploying a Manufacturing Execution System (MES), we achieved full-process digital oversight from order decomposition, material traceability, production scheduling, to quality tracking. A dedicated *"1+N" task force* was established for the BYD project, led by the general manager and comprising cross-functional teams from R&D, engineering, quality control, and five other departments. Through daily briefings, milestone alerts, and 3D simulation rehearsals, the production cycle was shortened by 20%. Prior to delivery, a novel customer-supervised manufacturing approach was implemented, with BYD technicians participating in key stage reviews and jointly optimizing 18 critical processes.  

The newly delivered split-type super charging stations support 1000V high-voltage fast-charging platforms, delivering a peak power of 480kW. Equipped with an intelligent power distribution system, they dynamically adjust output based on real-time vehicle demands. This successful delivery marks a significant breakthrough in our capabilities for high-end customized charging solutions. Moving forward, both parties will deepen collaboration to advance NEV energy replenishment technologies.  

The equipment has arrived at client’s pilot battery-swap stations nationwide and is scheduled to begin trial operations by the end of this month. Our company will continue to provide technical support for installation and commissioning, upholding exceptional quality to empower the green mobility ecosystem.

As of April 2025, the number of new energy vehicle charging piles in China has exceeded 10 million, marking a new stage of large-scale development of the energy replenishment network. This milestone not only achieved full coverage of all scenarios including cities, rural areas and expressways, but also significantly reduced the charging waiting time through the upgrade of fast charging technology and the optimization of the intelligent dispatching system, effectively alleviating "range anxiety". The improvement of charging infrastructure has injected strong impetus into the new energy vehicle industry, continuously increasing the electrification rate of private cars and accelerating the realization of carbon reduction targets in the transportation sector. This marks a crucial step for China towards a green travel ecosystem.

By April 2025, the number of new energy vehicle charging piles in China has officially exceeded 10 million, marking the basic formation of the world's largest new energy vehicle charging network. This milestone not only reflects China's leading position in the construction of new energy infrastructure, but also lays a solid foundation for the high-quality development of the new energy vehicle industry.

With the increase in coverage density, charging anxiety has become history

At present, the layout of charging piles across the country has achieved a three-dimensional coverage of "five minutes in cities, half an hour in rural areas, and full connection on expressways". On average, there is a fast charging station every 3 kilometers in urban public areas. The proportion of charging piles in highway service areas exceeds 95%, and the coverage rate of charging networks in remote towns and villages reaches 82%. With the popularization of private charging stations for families, users' vision of "charging as soon as they arrive" has become a reality, completely breaking the shackles of early "range anxiety" on market expansion.

The acceleration of technological iteration leads to a significant increase in energy replenishment efficiency

Behind the network of tens of millions of charging piles lies the strong support of technological innovation. The single gun power of the ultra-fast charging pile has exceeded 480kW, enabling "a 5-minute charge and a 200-kilometer range". The intelligent dispatching system, through vehicle-to-grid coordination (V2G) technology, dynamically matches the charging demand with the grid load, increasing the utilization rate of a single charging pile to over 35%. In addition, multiple energy replenishment solutions such as wireless charging and battery swapping are being advanced simultaneously to meet the needs of different scenarios.

Driven by both policy and market

This achievement is attributed to the deep integration of the "new infrastructure" policy and market mechanisms. The central and local governments have cumulatively invested over 100 billion yuan to subsidize the construction of charging facilities, and at the same time, they have activated the participation of social capital through policies such as land preferences and peak-valley electricity prices. Private enterprises and power grid companies have made collaborative plans, forming a virtuous ecosystem where "state-owned enterprises build the main trunk and private enterprises supplement the terminal", which has led to a 40% reduction in the construction cost of charging piles and a 60% increase in operational efficiency.

The industrial synergy effect has emerged

The well-developed energy replenishment network is exerting a multiplier effect: the penetration rate of new energy vehicles has exceeded 45%, driving technological breakthroughs in the battery, power electronics and other industrial chains. The combination of charging piles with photovoltaic and energy storage systems has given rise to a new type of integrated infrastructure featuring "photovoltaic storage charging and discharging", accelerating the transformation of transportation energy. It is estimated that the 10 million charging piles can replace over 20 million tons of fuel annually, contributing to the early realization of the carbon neutrality goal.

Looking ahead, with the unification of ultra-fast charging standards and the intelligent upgrade of charging piles, China's new energy vehicle industry will enter a virtuous cycle of "promoting usage through charging and driving production through usage", providing a Chinese solution for the global electrification of transportation.

In describing how the domestic new energy vehicle industry "from zero to one" to achieve rapid development, many news reports often appear on such a set of production data: On July 3 this year, China's 20 millionth new energy vehicle in Guangzhou GAC 'an production line; From the first car to the 10 millionth car, China took 27 years; It took only 17 months for China to break through 20 million units from the 10 million.

Indeed, over the past ten years, the evolving figures objectively show the speed of China's new energy vehicles all the way. So how exactly is this speed perceived? Probably, so fast that even the car company is a little behind the pace.

"Ten years ago, when I first entered the industry, new energy was still a very new concept, and the industry felt that new energy vehicles were the future direction, but the topic was still far away from us." "What's interesting is that the future is coming so fast and we are so caught off guard," said Lin Chang, who works for a Chinese leading car company. 

You know, ten years ago, the penetration rate of new energy vehicles in China has not yet exceeded 1%. Perhaps no one would have thought that in just a decade, that number has now exceeded 30%. Moreover, the development of the industry has also exceeded the imagination of the world: in the first quarter of this year, China's car exports surpassed Japan for the first time, ranking first in the world.

On this race track, after several rounds of "reshuffling" over the past decade, a series of independent brands with local characteristics have emerged, including the transformation and upgrading of traditional car companies, such as BYD, Geely, Changan, Chery, etc.; There are also known as "new car building forces" GAC 'an, Weilai, Xiaopeng, Ideal, Nezha, zero Run and so on. In the past two years, even Huawei, Ali, Baidu, millet and other Internet manufacturers have also laid out the layout of the car.

In the face of extremely fierce competition in the domestic market, the vast overseas market has gradually been regarded as a "good medicine to break the volume" by many car companies. Therefore, to find new opportunities in broad overseas markets has gradually become the consensus of car companies. "We should be firm in our strategy to go to sea, aiming for the medium-term goal of three years and the long-term goal of five to 10 years." Yang Kai, head of Geely Auto in Kazakhstan, is adamant.

At a number of international auto shows this year, China's new energy vehicles have come to the "C position" and attracted the world's attention. However, behind some bright data, how can China's new energy vehicles achieve a sudden rise in the international market? In the process of rushing to the world, what opportunities and risks are car companies facing? These will be the problems that China's new energy car makers must think about and face.

Lane change

"From manufacturing the first new energy vehicle to the millionth, it took 13 years; It took one and a half years to go from 1 million to 3 million. It took just nine months to go from three million to five million."

Another group of data comparison by the industry with relish, from the "new energy vehicle sales champion" BYD Automobile, the "acceleration" behind its data is undoubtedly a microcosm of the rapid rise of China's new energy automobile industry in recent years. On August 9 this year, BYD Group announced that the 5 millionth new energy vehicle produced by the company had rolled off the assembly line, becoming the first car company in the world to reach this milestone.

"This is a highlight moment for BYD, but also a highlight moment for Chinese car brands... I believe the era of Chinese cars has arrived." Wang Chuanfu, chairman and president of BYD Co., LTD., said at the launch of the 5 millionth new energy vehicle on the evening of August 9. It is worth mentioning that the night is not BYD "a single show", at the conference site, also exhibited SAIC, Dongfeng, Changan, Geely, the Great Wall, NiO, Xiaopeng and other Chinese independent brand sample cars.
