With the vigorous development of the new energy vehicle industry, the “slow charging and difficult charging” of new energy vehicles have always been the focus of attention within the industry. Liquid – cooled ultra – fast charging technology, as a new technology to solve the problem of “slow charging and difficult charging” of new energy vehicles, has become the focus of competition in the industry. Among them, the ultrasonic – welding – assisted liquid – cooled ultra – fast charging technology has become one of the keys to promoting the development of new energy vehicles with its unique advantages and important application value. In today’s article, let’s explore the field of ultrasonic – welding – assisted liquid – cooled ultra – fast charging technology in depth together.

I. What is liquid-cooled ultra-fast charging?

Liquid-cooled ultra-fast charging is a technology that sets up a special liquid circulation channel between the cable and the charging gun. Liquid coolant with heat dissipation function is added into the channel. The power pump is used to drive the circulation of the coolant, so as to take out the heat generated during the charging process and reduce the cable temperature. Since the power part of the system uses liquid cooling for heat dissipation and there is no air exchange with the external environment, an IP65 design can be achieved. At the same time, the system uses a large-volume fan for heat dissipation, with low noise and high environmental friendliness. Compared with the traditional air cooling system, the liquid cooling system has better cooling effect, faster charging speed and is safer for charging, greatly improving the working efficiency and service life of the charging system.
