In this paper, we propose assessment methodology of Electrical Stability for HFCV and EV (Electronic Vehicle) through a Simulation Model Development. The purpose of the simulation is to simulate the situations where insulation failure leads to leakage current and voltage rise.

The allowance of the symptoms in the view of human safety also can be assessed through the simulation. Through the simulation, high voltage system of the HFCV and EV can assessed considering electrical accidents.

The assessment of the high voltage system of HFCV and EV is achieved through the simulation. And also we can supplement high voltage system design by the results of the simulation.
