Range extension control system of electric vehicle based on optimal torque distribution and cornering resistance minimization

Abstract

Recently, electric vehicles (EVs) have received substantial attention. However, EVs have several problems that prevent their widespread use. In particular, the cruising distance per charge is the most important parameter. In order to solve the problem of a short cruising range, there have been many efforts to improve battery capacity. In contrast, in this paper, range extension control systems (RECSs) are proposed to enhance the efficiency based only on control technologies. Two types of range extension control systems are introduced, and their effectiveness is confirmed by experiments.
