Intelligent monitoring liquid-cooling high-power charging cable for new energy automobile and production process

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of electric wires and cables, and in particular relates to a new energy vehicle intelligent monitoring liquid-cooled high-power charging cable and a production process. Background technique [0002] New energy vehicles are the only way for my country to move from a big automobile country to a powerful automobile country, and it is a strategic measure to deal with climate change and promote green development. Compared with traditional cars, new energy vehicles have excellent characteristics such as large space, low cost, strong power, energy saving and environmental protection, and the national attention rate is quite high. However, the development of new energy vehicles is limited due to low charging efficiency. In order to solve the problem of the charging time of new energy vehicles, the manufacturer has developed a high-power new energy vehicle charging cable, but the long-term power supply of the high-po...

AI Technical Summary

Problems solved by technology

In order to solve the problem of the charging time of new energy vehicles, the manufacturer has developed a high-power new energy vehicle charging cable, but the long-term power supply of the high-power charging cable will cause the temperature of the cable to rise and affect the current carrying capacity of the cable, especially in summer when the temperature is relatively high. When it is high, it will seriously affect the heat dissipation of the cable. If the surface temperature of the cable is too high, it will affect the use and the life of the cable will be reduced.
