Abstract

The invention discloses a small-wire-diameter high-power charging cable structure and a charging device. The small-wire-diameter high-power charging cable structure comprises a conductor, a cavity for accommodating the conductor is formed in the insulating sheath, the insulating sheath is provided with an inner wall facing the cavity and an outer wall deviating from the cavity, and the insulating sheath forms a liquid flow channel for cooling liquid to flow between the inner wall and the outer wall; the extending directions of the conductor, the insulating sheath and the liquid flow channel are parallel, and the conductor is in contact with the inner wall of the insulating sheath, so that heat on the surface of the conductor is taken away through flowing of the cooling liquid. The invention provides a small-wire-diameter high-power charging cable structure and a charging device, and solves the technical problem that the wire diameter of a current liquid cooling cable is relatively large.

Description

technical field [0001] The invention relates to the field of charging cables, in particular to a small wire diameter high power charging cable structure and a charging device. Background technique [0002] In recent years, with the rapid development of new energy technology, a large number of electric vehicles have entered the home and commercial fields, and users have higher and higher requirements for battery capacity, driving range, and charging speed, and high-power charging technology has gradually developed. High-power charging piles have high voltage and high current, which will generate a lot of heat during use, and the higher the power, the easier the cable is to heat up, and the heated cable has the risk of causing a fire. [0003] In order to solve the problem of the temperature rise of the cable during the charging process, new products such as liquid-cooled cables, liquid-cooled charging guns, and liquid-cooled sockets have gradually been produced in the market,...
