The Republic of Korea has implemented energy economy labeling for electric vehicles since 2012. The energy economy of vehicle can vary depending on various conditions. Electric vehicle has a significant change in energy economy depending on ambient temperature due to its chemical characteristics and air conditioning system different from that of the internal combustion engine vehicle. In this study, energy economy characteristics were analyzed through Multi Cycle Test at -7℃, 10℃, 25℃ and 35℃ ambient temperatures. The changes in energy economy in city, highway and combined of electric vehicles were compared. In addition, high voltage batteries, which are main components of electric vehicles, measured current and voltage according to changes in ambient temperature, and analyzed high voltage battery resistance characteristics according to ambient temperature
