his article reviews integration approaches and, by employing finite element analysis (FEA), compares thermal management solutions for the combined electric motor and power electronics systems for electric vehicles. Integration of power electronics into the electric motor helps achieve higher power densities in the electric traction drive systems. The benefit of integration from the thermal management perspective is the potential for using a single-fluid loop instead of two separate cooling systems for the electric machine and the power electronics/inverter.


The number of vehicles on roads with electric propulsion systems is constantly increasing. The global market share of electric and hybrid vehicle sales increased from 2.5% in 2019 to 4.2% in 2020 [1]. According to Deloitte Insights forecasts, by 2030 electric vehicle (EV) market share of new car sales will reach 27% in the United States, 42% in Europe and 48% in China [2].
