Summary:

This paper describes the safety test simulation of electricalshock of FCV (Fuel Cell Vehicles) on human. Since FCV operates withhigh voltage, it is very dangerous to touch on or near theconductive parts. It may hurt human even when conductive parts aresurrounded by protectors such as barriers or enclosures. Alsovarious modes of a vehicle, such as driving, idle and failure, canaffect electrical shock. It is difficult to carry out fieldexperiments about electrical shock for FCV because of manycombinations which depend on the operating voltages and the modesof a vehicle. And electrical safety of FCV must be verified beforethe manufacturing process. These are the main purposes of thisstudy.MATLAB Simulink is the tool to conduct the simulation. All ofthe electronic devices in an FCV and a human body were modeled tomeasure current through human body when human touches on FCV. Weperformed the simulation with respect to driving, idle and failuremode. Result of this study shows that in case of the isolationresistances between the electrical units and the electrical chassisare less than 221.7 kΩ (DC) or 66.3 kΩ (AC), when human body ismodeled as 500 Ω resistances, it may cause severe damage on human.The proposed simulation method can be used to establish thestandard value of isolation resistance and the standard value ofelectrical shock on human
