In a method for determining an optimal capacity of a DC/DC converter for an electric vehicle, there is statistical modelling of firm loads and instantaneous loads with frequency and duty-on ratio, by summing up firm loads, arranging instantaneous loads in a way in which a turn-ON time of each instantaneous load does not occur simultaneously during a cycle in which another instantaneous load occurs, obtaining a total load by summing up the instantaneous loads and the firm loads during a particular cycle, and determining a capacity of the DC/DC converter such that, during the cycle, the amount of a charged capacity and the amount of a discharged capacity of an auxiliary battery are approximately the same.
