Motor vehicles have been traditionally propelled by fossil fuels. The burden on the environment has been kept added by ever-increasing emissions due to the rapid increase in motor vehicles. The vehicle emissions are regarded as one of the main causes of global warming. Alternative fuels and environment-friendly vehicles have been developed to cope with environmental pollution, oil price and depletion of fossil fuels. Environment-friendly vehicles have been developed and supplied to the domestic market. Especially electric vehicles, Low-speed Electric Vehicles , and Online Electric Vehicles propelled by electricity have been recently developed. The pilot program to promote electric vehicles has been already implemented. Even though there is an advantage that electric vehicles which use electricity as propulsion power do not emit gaseous emissions, there are many disadvantages, such as long charging time, high price and short life of batteries. In this study the procedures, methods, standards and recent trends for the test of maximum driving range of an electric vehicle under the fully charged condition which draws attention have been studied.

An automobile has become essential in our daily life. Rapid motorization has adverse effects in safety and envirionment domestically as well as internationally. Thus world-wide regulatory communities endeavor to improve safety, to protect environment, and to save energy by internationally harmonizing vehicle technical regulations. Automotive markets have become global without borders after WTO was established. Vehicle technical regulations emerge as technical barriers to trade(TBT) while customs barrier gave away. From the TBTs point of view international harmonization becomes increasingly important. In this paper the activities of United National Economic Commission for Europe Working Party 29 (UN/ECE/WP29, World Forum for Harmonization of Vehicle Regulations) and trends of development of vehicle technical regulations under 1958 Agreement and 1998 Agreement have been studied.

In these days, advanced vehicles such as hybrid electric vehicle, electric vehicle and hydrogen fuel cell vehicle are being developed and researched so rapidly and international standards is being constantly updated. Domestic vehicle safety standards of eletro-magnetic compatibility is recently updated and we feel the need to check if advanced vehicle in being developed is conformed or not with updated standards. For this reason, we have tested about conformance of electro-magnetic compatibility safety standards for Hydrogen fuel cell vehicles as representative of advanced vehicles. Broadband emission tests, narrowband emission tests and immunity tests of hydrogen fuel cell vehicles were carried out under real vehicle test in the EMC chamber. The results presented in this study indicate that Hydrogen fuel cell vehicles in recently developed are conformed with updated vehicle safety standards.

Successful commercialization of electric vehicle is depended on research and development level of traction battery being main component of Electric vehicle. Standard test procedure for Li-ion traction battery for performance, reliability and safety is under discussion in the standard of ISO-12405. This paper evaluated Energy-Capacity, Power and Energy efficiency at fast charging of Lead-acid and Li-ion battery pack in the view of ISO/DIS 12405-2. By the tests, This paper confirms the certain performance gap between commercialized Pb-acid and Li-ion traction battery pack. This performance gap would be caused by different material characteristic including chemical potential and internal resistance. The result of this paper could be applied to basic data when designing Battery Management System of traction battery pack. Also this paper evaluated the validity of test procedures of ISO/DIS 12405-2 by actual test.

This paper is about electromagnetic compatibility test of neighborhood electric vehicle and electric vehicle, when they are in charging mode connected to the power grid. Disturbances from sources employing on-board system in electric vehicle cause emissions and immunity. Electromagnetic regulations in UN/ECE WP.29 is under working about vehicles providing coupling systems for charging the RESS regarding the control of emissions and immunity from this connection between vehicle and power grid. However there is no any accurate domestic EMC regulation for charging mode. So this research shows test methods and some results related electric vehicle"s charging mode.
