Development of a battery electric vehicle and its Evaluation  by Prof. Shinichi Domae, Kyoto University  of Advance Science, Japan

Abstract:

The advanced motor system consisting of a 3-phase Y-inverter and a Halbach motor is under development and will be equipped to a small battery electric vehicle (BEV) in the near future. In the meantime, its energy conversion efficiency evaluation method has been developed. This paper presents a calculation method of the energy conversion efficiency of BEVs during driving. The progress of the global navigation satellite system (GNSS) and the widespread use of road elevation database enable a tractive power measurement. The calculation method showed almost the same energy conversion efficiencies on the three different routes. The results demonstrate the universality of the method and raise the possibility of benchmarking of the power conversion efficiency of any of various BEVs.
