At the same time, compared with ordinary charging guns, they can reduce the weight by nearly 50%. However, the price of liquid-cooled charging guns is still at a relatively high level. According to the new information briefing of Rifeng Co., Ltd. in 2022, domestic liquid-cooled charging guns are still in the initial stage, and the market price is over 20,000 yuan, while the price of ordinary DC charging guns is 1,000-2,000 yuan. With the increasing demand for liquid-cooled charging guns driven by the promotion of 800V fast charging, their penetration is expected to exceed expectations.
7. Liquid-cooled super charging cables have the advantages of large current, light weight, thin wire diameter and fast heat dissipation.
The cables connected to the standard DC charging gun at home are generally 35mm2 in cross-section, which can carry 125A. Take the charging power of 400kW at 800V as an example, the current to costa rica number data be carried is 500A, and the cross-section needs to be increased to reduce the heat caused by the increase in current. The liquid cable has a liquid cooling pipe that can carry away the heat generated by the cable. The diameter of the liquid cooling cable for the 500A charging gun is generally only 35mm, and its weight is about half that of the traditional cable. At the same time, it can reduce the heat damage caused by high charging power.
