Problems solved by technology

However, there are serious problems with the cables of electric vehicle charging piles. They are often not discovered in time because the charging cables emit a large amount of heat during the charging process, causing fires, which are not uncommon even in developed regions such as Europe and the United States.

Abstract

The invention discloses an electrical-vehicle charging pile cable capable of transmitting temperature measurement and control signals. The cable includes a cable core which includes a live wire core, a null line core, a ground wire core and a temperature control wire core, wherein the live wire core includes a live wire conductor and a first insulating layer which wraps externally the live wire conductor; the null line core includes a null line conductor and a second insulating layer which wraps externally the null line conductor; the ground wire core includes a ground wire conductor and a third insulating layer which wraps externally the ground wire conductor; the temperature control wire core includes two signals transmission lines and each signal transmission line includes a temperature control conductor and a forth insulating layer which wraps externally the temperature control conductor; the two signal transmission lines are externally wrapped sequentially with a metal wrapping tape shielding layer and a metal braiding shielding layer after being mutually stranded; the cable core is externally wrapped with a wrapping tape layer in a lapping manner; and the wrapping tape layer is externally wrapped with an outer protection layer in a pressing manner. The temperatures of the cable and a plug can be monitored in a real-time manner in a charging process and the power supply can be cut off timely when the temperature of the plug is too high so that it is prevented that overheat causes a fire disaster.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an electric vehicle charging pile cable capable of transmitting temperature measurement and control signals. Background technique [0002] Due to the serious environmental pollution caused by automobile exhaust, electric vehicles, as a zero-emission and pollution-free means of transportation, will become the development trend of the future automobile industry. However, there are serious problems with the cables of electric vehicle charging piles. They are often not detected in time due to the large amount of heat energy emitted by the charging cables during charging, causing fires, which are not uncommon even in developed regions such as Europe and the United States. There is an urgent need for an electric vehicle charging pile cable that can monitor the temperature in real time during the charging process, and can withstand high temperature and flame retardancy, has high oil resi...
