The invention relates to a high-power superconductive charging connection device and system for an electric vehicle. The device comprises a charging pile which is used for obtaining alternating current of a power grid and converting the alternating current into direct current; the superconductive charging connection device is used for connecting the charging pile and a battery charging module of the electric vehicle; and the liquid nitrogen cooling circulation assembly is used for carrying out cooling operation on the charging pile and the superconductive charging connection device. The superconducting charging wire is made of a high-temperature superconducting material and can reach a superconducting state after being cooled by a liquid nitrogen circulating system, and the resistance in the wire is zero. Through the technology, a high-power charging scheme of the electric vehicle can be realized, the charging speed of the electric vehicle is improved, the sectional dimension and weight of a high-power charging wire are reduced, the charging resistance loss is reduced, energy is saved, and the development of the electric vehicle industry is promoted.
