Luoyang Zhengqi Machinery's liquid-cooled cable for high-power charging piles successfully developed

Project Name: R & D Project of Zhengqi Mechanical High-Power Charging Pile Liquid-Cooled Cable

Project Overview: The project mainly researches and develops liquid-cooled cables, liquid-cooled charging guns, and liquid-cooled sockets for high-power charging piles for new energy vehicles. The project combines traditional liquid cooling technology with new energy vehicle charging products to solve the problem of excessive temperature and current limitation during charging, and achieve fast charging.

Many people have to consider charging when buying new energy vehicles. Compared with fuel cars, which can be refueled in a few minutes, charging new energy vehicles takes several hours, which is quite time-consuming. However, with the advent of high-power charging piles in the future, new energy vehicle charging is expected to be fast and good, and here is the contribution from "Luoyang Innovation".

"Liquid-cooled cable samples for high-power charging piles have been successfully developed, and now we have received an inquiry call from the charging pile manufacturer." Yesterday, Zang Chongqing, general manager of Luoyang Zhengqi Machinery Co., Ltd. reporter.

Zhengqi Machinery is located in the old city, with a small scale, but is well-known in the field of water-cooled cables in the domestic photovoltaic industry. The person in charge of the company believes that enterprises cannot survive without innovation, and new products and technologies are always the core competitiveness of enterprise development.

In recent years, with the continuous development of the domestic new energy industry, the range of new energy vehicles has continued to increase, the battery capacity has increased, resulting in excessive charging time, and fast charging has become an urgent need for the development of the new energy vehicle industry. At present, the power of public charging piles in China is mostly about 60 kilowatts, the power is small, the charging time is long, and the user's charging experience is not good. An important factor limiting the development of high-power charging piles is the lack of high-power charging cables.

Zang Chongqing introduced that the power of the charging pile is too large, which easily causes the cable to heat up, resulting in unsafe and unstable factors. Liquid-cooled cables are special cables used for high-current heating equipment. Compared with ordinary cables, liquid-cooled cables can conduct heat while dissipating heat with cooling liquid. Its cooling system can effectively reduce the temperature and allow higher currents to operate without damaging the cables, which makes it possible for liquid-cooled cables to be equipped with high-power charging piles.

Relying on the existing technical advantages in the field of water-cooled cables, Zhengqi Machinery has started research and development on liquid-cooled cables for high-power charging piles since last year. At present, the company has successfully developed a liquid-cooled cable sample for a 600A (amp) high-power charging pile. The sample cable has an outer diameter of 39 mm, and under the load of 600A (ampere), the temperature can be controlled below 70 degrees, which is the industry-leading level. For example, a high-power charging pile equipped with a 600A (amp) liquid-cooled cable can be filled with a new energy vehicle, and the time can be shortened to more than ten minutes.

"The successful development of the cable sample is only the first step. This year we will continue to develop high-power charging liquid-cooled sockets and liquid-cooling charging guns, and strive to provide products with high-power charging piles as soon as possible to contribute to the new energy automobile industry. "Zang Chongqing said. (Sun Xiaorui, reporter of Luoyang Daily)
