▎ 摘　　要

NOVELTY - The system has an electric energy transmission guide rail (2) and a charging connection component (1) connected with the external charging system. One end of the electric energy transmission guide rail is connected with one end of the charging connection component. The electric energy transmission guide rail is an alternating current (AC) electric energy transmission system (201) and/or a direct current (DC) electric energy transmission system (202). The electric energy transmission guide rail comprises a spiral portion. The electric energy transmission main portion is made of aluminium, phosphorus, tin, copper, iron, manganese, chromium, titanium and lithium. USE - Electric energy transmission system for use in charging device of electric vehicle (all claimed). ADVANTAGE - The system is enabled with the characteristics of excellent electrical conductivity, light weight, low cost, electromagnetic interference avoidance, simple structure and convenient assembly during high-current charging. The large current charging requirements can be easily met. The heating problem of the electric energy transmission system after electrifying can be effectively reduced. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the electric energy transmission system for vehicle.
