Abstract

A new energy automobile charging pile electric wire provided by the application aims to reduce the charging time of a charging pile under the premise of guaranteeing the safety and the reliability. Compared with the situations in the prior art that the charging pile adopts a pure copper material electric wire, the charging time is 4 hours to 8 hours, and the charging time of an electric automobileis much longer than the refueling time of a fuel oil automobile, the new energy automobile charging pile electric wire provided by the present invention adopts a five-layer structure, the core conductor materials are a graphene material and a sliver-copper alloy material, and the outer layers comprise a shielding layer, an insulating layer and a protection layer. The new energy automobile charging pile electric wire is low in resistivity and strong in conductivity, is high-temperature resistant and corrosion resistant, has the ductility, the plasticity and the wear resistance, enables the charging time of the conventional charging pile to be shortened substantially under the premise of guaranteeing the safety and the reliability, and lays a foundation for the wide popularization and application of the new energy automobiles.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a charging pile wire for a new energy vehicle. Background technique [0002] Today, as environmental problems and energy crises become more and more serious, energy conservation and emission reduction has become a new topic facing the world, and green transportation has become a key direction for countries to develop energy conservation and emission reduction. As a representative of green transportation, electric vehicles have the advantages of energy saving, environmental protection, and cleanliness compared with traditional fuel vehicles, which reduce the environmental and economic costs of using vehicles, and have attracted more and more attention from the government, enterprises and the public. The rapid development of electric vehicles and the large-scale construction of electric vehicle charging stations have promoted the transformation of transportation energy and reduced energy ...
