ABSTRACT Eco-friendly car market, which involves hybrid car, electric vehicle, plug-in electric vehicle, hydrogen fueled cell vehicle is expected to be extended locally and abroad amid the high price of petroleum and the enhancement of regulations on environments. Electric vehicles (EV), called Zero Emission Vehicles (ZEV) are perceived as an alternative by using the battery due to all kinds of regulations on cars. In order to avoid problems with electromagnetic interference, Extensive Electromagnetic Compatibility (EMC) and componenets of vehicles are being developed.
As the electric cars are the ones that need recharging after driving, it may cause social problems when electromagnetic waves are over-generated while battery is being recharged at our home or work places. So the electric cars need to be evaluated by two methods. One is driving mode with no charging on the power grid which is the existing test method from old times. The other is the RESS in charging mode coupled to the power grid. Recently various researches are discussing about battery recharging methods of electric cars. However, according to vehicle’s manufacture, the charging type and the position of inlet in vehicle are quite expensive. Real experiments of several electric vehicles were conducted in EMC chamber in KATRI lab. This study shows the differences in the test results of two different methods (driving & charging mode) and provides proper test setup according to the location of inlet.
