Abstract
Recently, vehicles such as hybrid electric vehicle (HEV) and electric vehicle (EV) are actively researched. This paper focuses on EV with a DC-DC converter. EV is inefficient as the battery supplies all power through the DC-DC converter all the time. This paper proposes a high efficient energy conversion system (HEECS) using two batteries: a main battery and a sub battery. The main battery supplies fundamental power without passing through the DC-DC converter. The sub battery supplies additional power through the DC-DC converter. High efficiency of 99.6 % was experimentally confirmed in this paper. Proposed high efficient energy conversion system (HEECS) makes it possible to improve the running distance per charge of EV.
