【Abstract】 Radiation emission and conducted emission exist in the charging process of electric vehicles.Through EMItesting of vehicles underdiferent distribution parameters，different charging currentand different phase number，it is found that charging current has litle influenceonradiation emisson and conducted emission.Changing distribution parameters willcausethechangeof broadband signal ofconducted emission tobecorrelated with theoriginaltestresults. The radiation emission test results of single-phase AC charging are lower than those of three-phase testing.
