Study on the validation measurement of current harmonic for electric vehicle in charging mode

In order to effectively resolve the environmental issues of energy consumption and the emission of exhaust, electric vehicle with green, clean and energy-saving characteristics has been developed and will become more and more popular on the road. Electric vehicle is powered by its traction battery and needs to be continually charged by coupling to the public power mains, which may result in some interference along the charging cables. To sufficiently prevent the mutual interference between electric vehicle and the power mains, the international vehicle regulation ECE R10 (rev4 & rev5) had put forth the measurement method of current harmonics on electric vehicle's charging system. Therefore, this paper refers to vehicle EMC compliant test procedures to study if the measurement result of current harmonics will be influenced by different measuring method or test duration when the electric vehicle is in REESS (Rechargeable Energy Storage System) charging mode.
