Design of a 2 in 1 motor to increase the efficiency of electric vehicles

The requirements for the climatisation of electric vehicles largely depend on the vehicles usage location. For example, electric vehicles operated in European countries require heating during the winter season, while those operated in equatorial regions face cooling load throughout the year. To date, the low range for a given battery charge remains the single-most important factor hindering the widespread acceptance of electric vehicles. The principal electrical load of an electric vehicle used in equatorial regions comprises of the traction motor and the air-conditioning compressor motor. These high power loads expedites the battery drain, leading to poor cruise range. The paper proposes a novel design solution geared towards improving the overall operating efficiency of these motors by integrating them into a single housing.
