High-power water-cooled EV charging cable Introduction：
The high-power DC charging cable uses liquid cooling technology to cool down, so that the charging cable maintains a low constant temperature during the charging process, and overcomes the thermal damage to the charging gun, charging cable, and charging pile, thereby increasing the charging current. The principle is to add a liquid cooling circulation system inside the cable, and allow the cooling system and the charging system to coexist through the sealed circulation connection inside the connector. The high-power liquid-cooled DC charging cable can fully charge or quickly charge the battery of an electric vehicle in a short time to increase the cruising range, meet customer needs, improve the utilization rate of electric vehicles, and eliminate users' concerns.

What medium does the liquid-cooled charging cable use to dissipate heat?
Specifically, the high-power charging cables on the market are oil-cooled and water-cooled depending on the cooling medium. Oil cooling is to design the insulating layer as an oil pipe, directly immerse the conductor part in oil, and increase the current carrying capacity through the circulation of the insulating oil. The terminal of the oil cooling gun is a specially designed circulation system, which not only ensures the circulating cooling of the liquid, but also In order to ensure the safety of insulation, it will not conduct electricity. This type of cooling cable has an excellent cooling effect and can achieve a large current carrying capacity of 600A. The other is a water-cooled cable, that is, some water pipes are added inside the cable. The cooling medium is a non-insulated liquid, which can be pure water or antifreeze. The heat generated by the cable is transferred into the liquid through the contact between the insulation and the water pipe. , And then take away the heat through the circulation of the liquid to form a cooling effect and provide a form of current-carrying capacity. Because this form is indirect cooling, the charging current may not be larger than that of oil cooling, but due to the advantages of structural design, the outer diameter of the charging cable can be made smaller, which is especially suitable for customers to use, and has a very superior experience.
