Driving Range Parametric Analysis of Electric Vehicles Driven by Interior Permanent Magnet Motors Considering Driving Cycles

Abstract

This paper presents parametric analysis of driving range of electric vehicles driven by V-type interior permanent magnet motors aiming at maximum driving range, i.e., minimal total energy consumption of the motors over a driving cycle. Influence of design parameters including tooth width, slot depth, split ratio (the ratio of inner diameter to outer diameter of the stator), and V-type magnet angle on the energy consumption of the motors and driving range of electric vehicles over a driving cycle is investigated in detail. The investigation is carried out for two typical driving cycles with different characteristics to represent different conditions: One is high-speed, low-torque cycle-Highway Fuel Economy Test and the other is low-speed, high-torque cycle-Artemis Urban Driving Cycle. It shows that for both driving cycles, the same parameters may have different influence on the energy consumption of the motors, as well as driving range of electric vehicles.
