High-power charging wire for electric automobile

The embodiment of the utility model provides a high-power charging line for an electric vehicle. The high-power charging line comprises a main power line, an auxiliary power line, a cooling pipe, a signal line, a control line and a filler which are wrapped in a sheath, the main power line comprises at least one first wire and a second wire. One cooling pipe is completely surrounded by the main power line, the auxiliary power line, the signal line and the control line, and the other cooling pipe is at least partially surrounded by the main power line, the auxiliary power line, the signal line and the control line; gaps formed among the main power line, the auxiliary power line, the signal line and the control line are filled with the filler. As an insulating layer of the main wire core of the second wire is cancelled, the sectional area of the conductor can be increased and the heating value during large-current charging can be reduced on the premise that the twisting outer diameter is not changed; or on the p
