The invention discloses a new energy automobile intelligent monitoring liquid cooling high-power charging cable and a production technology, and the cable comprises a main cable core which is formed by twisting a power wire core, a control wire core, a grounding wire core, an auxiliary wire core, a composite cooling pipe and an optical fiber unit, and a main cable core wrapping tape and a sheath which sequentially wrap the main cable core. A gap of the main cable core is filled with cable core filler, cooling pipes are arranged in the power wire core, the control wire core and the auxiliary wire cores respectively, the power wire core is tangent to the control wire core and the grounding wire core respectively, the auxiliary wire cores are arranged on the two sides of the control wire core, and the composite cooling pipe is arranged in the gap between the power wire core and the grounding wire core. And the optical fiber unit is arranged in a gap between the power wire core and the control wire core. The temperature of the cable in the charging process is monitored at any time through the optical fiber unit, use safety is ensured, the temperature of the power wire core and the control wire core is reduced through the cooling pipe, the current-carrying capacity is more than three times that of a common charging pile cable, charging efficiency is high, heat dissipation performance is good, and the service life of the cable is prolonged.
