A study on safety issues and analytical evaluation of stresses for HVDC cable in electrical vehicle

Abstract

Electric vehicles (EVs) are fast emerging as a desirable transportation to cut the environmental pollution across the world. The main component in EVs are battery, power electronics, electric motor and high voltage cable. Their failure in EVs may result in sever system breakdown, or even life threat. Currently in heavy EVs such as bus, trucks, sports car, the voltage levels and current levels are far higher than the level that people can endure. Among these components high voltage cable is required for safer transfer of electrical energy without causing any failure of insulation. Due to heat produced by the electrical EVs components, temperature of the overall electrical system in EV increases and it causes serious concerns for safety issues mainly for the insulation property of the cable. In electric vehicle high voltage safety is utmost important and ensuring the passenger's safety is important factor in research ecosystem. In this paper addresses the high-voltage safety of an electric vehicle and analytically evaluate the electrical and thermal stresses of the high voltage DC cable.
