Study of electric arc parameters during the extraction phase for automotive connectors

International audienceComfort, safety, communication, control with assistance (antilock brake system, seat heating, multimedia, etc.), and safeguarding the environment are many factors that are included in the new generation of vehicles. The increase in the number of electronic and electric systems leads to a high level of vehicle control. To answer this high electric power demand, it will be necessary to triple the voltage of the batteries (from 14 to 42 V). The objective of this work is to study the arc phenomenon that can occur in an accidental way during the use of a high electric power and particularly during the extraction phase of the male part from the female part of the automotive connector. It was observed that this can be characterized by both its energy and its temperature. The amplification of the contact current from 14 to 42 V d.c. considerably increases arc damage
