Design Approaches and Control Strategies for Energy-Efficient Electric Machines for Electric Vehicles—A Review

Abstract: The market penetration of electric vehicles (EVs) is going to significantly increase in the next years and decades. However, EVs still present significant practical limitations in terms of mileage. Hence, the automotive industry is making important research efforts towards the progressive increase of battery energy density, reduction of battery charging time, and enhancement of electric powertrain efficiency. The electric machine is the main power loss contributor of an electric powertrain. This literature sur… Show more

“…This indicated that the global fuel economy improvement would very likely lag behind the GFEI target of halving new vehicle fuel economy by 2030. On the other hand, the global production and purchase of hybrid/electric vehicles are still limited due to a lack of charging infrastructure [55] and insufficient mileage [56].…”

“…Different motor types for vehicular applications have been introduced over the past few years. According to research conducted in [17][18][19], state-of-the-art EVs are equipped with Induction Motors (IMs) and Permanent Magnet Synchronous Machines (PMSMs). In addition, Switched Reluctance Motors (SRM) have gained interest for traction applications [20][21][22].…”

“…At the moment, most of the electric vehicles on the market such as Tesla, Mercedez-Benz EQC, Nissan Leaf and BMW i3 are equipped with single gear transmissions owing to the large speed range and low-speed high-torque characteristics of electric motors [1,2]. Some electric vehicles use two motors on the front axle and rear axle respectively to further improve the vehicle dynamic performance [3]. The multi-gear and multi-motor powertrains are widely researched in academia with the motivation of improving the electric vehicle energy economy and dynamic performance.…”
