In the 1980s, reform and opening up outlined a clear path for China's rapid economic development. By the 1990s, in just ten years, China had become the world's second largest electrical technology application market.

In the 1870s, the second worldwide technological revolution was marked by the widespread use of electricity. Since then, mankind has entered the " electrical age" from the " steam age ". In the next hundred years or so, electricity will bring changes to mankind that far exceed the evolution of mankind over thousands of years.

In the 1980s, reform and opening up outlined a clear context for China's rapid economic development. By the 1990s, in just ten years, China became the world's second largest electrical technology application market. However, the application of electrification technology in developed countries such as Europe and the United States has become increasingly mature, and the scale growth of new electrical technologies has gradually become weak. Coupled with the acceleration of globalization, developing countries have become an important place for developed countries to innovate electrical technology on a global scale. Driven by both external forces and domestic demand, my country's electrical enterprises have sprung up in China. It was at this time that Yingjie Electric sprouted in Deyang City, Sichuan Province, which is "China's major technical equipment manufacturing base".

1996, Yingjie Electric was officially established, focusing on the R&D and manufacturing of industrial energy equipment represented by power controllers and special power supplies. This R&D lasted for 26 years. In the 26 years of ups and downs, Yingjie Electric has kept pace with the times, is future-oriented, keeps pace with the times, and is pioneering and innovative. The products it develops and produces not only cover traditional industrial fields such as petroleum, chemical industry, metallurgy, machinery, and building materials, but also extend to emerging industries such as photovoltaics, nuclear power, semiconductors, and environmental protection. On February 13, 2020, Yingjie Electric was listed on the GEM of the Shenzhen Stock Exchange, entering a new stage of development.

In the process of the birth of Yingjie Electric, a major industry that affects China and the world is also quietly sprouting. In 1992, academician Qian Xuesen wrote a letter to the country suggesting the development of an electric vehicle project. Zou Jiahua, then Vice Premier of the State Council, personally replied to Qian Xuesen to jointly discuss electric vehicle research issues. Since then, the "Electric Vehicle Research Plan" has been included in the "Eighth Five-Year Plan" and has been designated as a national key scientific and technological project. After a generation of unremitting efforts, the new energy vehicle technology continued to mature. Finally, in 2010, China's new energy vehicles began to enter the industrial production stage. At this point, a large number of Chinese car companies such as BYD , Ideal, NIO , etc. have begun to compete on the same stage and shine in the new field of new energy vehicles.

In 2016, China's new energy vehicle production reached 455,000 units, and this figure is growing at an alarming rate every year. The supporting industries are also booming. Yingjie Electric, which keeps pace with the times, feels the strong impact of new energy vehicles, so it decided to enter the most important supporting industry for new energy vehicles - the new energy charging pile field, and prepares to flex its muscles in this field.

In January 2016, Weiyu Electric, a wholly-owned subsidiary of Yingjie Electric, was officially established in Deyang City, China, focusing on the production of charging pile power modules and charging pile/station R&D and manufacturing. As technology matures, my country's charging field has formed a pattern in which DC fast charging is the mainstay, AC slow charging is the supplement, and other charging methods are supplementary. As the public's requirements for charging experience continue to increase, my country's charging technology is developing in the direction of "convenience, efficiency, safety, and intelligence." Against this background, DC charging piles have become the focus of the market with their advantages of fast charging speed. However, due to the complex production process and unstable operation of DC charging piles, the production cost and operating cost of the product have greatly increased.

In order to solve the pain point problem of DC charging piles, Weiyu Electric has developed "programmable charging pile power controller" technology after years of technical research and development. This technology highly integrates the high-voltage main circuit unit, main control unit, BMS auxiliary power supply unit and working power supply unit in the DC charging pile.

A single system can complete multiple functions such as BMS power supply, vehicle communication, charging process control, DC energy metering, overcurrent protection, short-circuit protection, etc. It improves operational stability, reduces failure rates, and also reduces later maintenance costs. On January 17, 2021, the programmable DC charging pile power controller obtained a German patent, and other patents are also being certified.The research and development of

programmable charging pile power controller is a big step taken by Weiyu Electric in the charging pile market, and it also allows Weiyu Electric to gain more competitiveness in the market.

Looking back at the development history of Weiyu Electric and Yingjie Electric, it is not difficult to find that at the key nodes of the development of the times, both Yingjie Electric and Weiyu Electric can well take advantage of the momentum of the times and turn it into the strength of their own development, continuously expand their business breadth, tap the depth of development, and become the trendsetter of the times in one field. This power of taking advantage of the situation comes from Yingjie Electric's grasp of trends and opportunities, and is also a concrete manifestation of the company's vision. This is the talent of Yingjie Electric and even Weiyu Electric. I believe that with the help of this talent, Weiyu Electric can fight more and more courageously in the industry, maintain the vitality of upward development, and welcome a broader market.
