“…However, as mentioned, such structures are carried out in a limited space in which such systems need effective cooling to achieve proper miniaturisation and high‐power output and durability 134,135 . Studies on the thermal effects of electric motors in EVs have shown that motor heat generation reduces range, charging, longevity and endangers its safe operation 136,137 . Furthermore, knowing that EV's lithium batteries' operating temperature ranges from −40 to 84°C, 66 and the heat generated from the motor can reach up to 221°C while the requirements for motor control restrict the maximum temperature to 150°C, 138 heat management gains significant importance.…”

The most remarkable difference between electric vehicles (EVs) and conventional ones is the fuel burning dependency of the internal combustion engine, while the emerging EVs operate on electric motors. These alternations create staggering shifts in both lubricants' market demand and performance specifications. Lubricants for electrical powertrain constitutes greases, transmission oils, and lubricants for auxiliary systems and do not rely on engine oils as internal combustion vehicles. The new standards will be more focused on lubricants' electrical properties such as breakage voltage and conductivity, coupled with tribological performance under high rpm, corrosion resistance and thermal management benchmarks. This paper thematically reviews the different studies performed with nanolubricants, and how they match EVs' operational requirements. Conclusions from this study can be considered as guidelines for the potential application of nanolubricants in EVs and possible future research that can be accomplished on the topic.

More efficient cooling systems are an enabler for the increase in power-density in an electric traction motor. Contemplating to existing reviews, this paper presents a comprehensive collection of heat transfer mechanisms for the different heat removal techniques used in electric traction motors. In the first section, an overview of various cooling concepts in existing and future traction motors is presented and the cooling approaches are compared. The following literature review compiles geometry-based calculation formulas of the different mechanisms of cooling heat transfer applied in motor-technology. Furthermore general heat transfer phenomena appearing in electric traction motors are reviewed and compiled for easy access. Various specifically relevant aspects, including rotor shaft cooling, different spray cooling concepts, different air convection phenomena, bearing heat transfer and the stator-housing-contact, are examined in more detail. For validation of the review result, based on a well-known motor design a thermal analysis and comparison of the different cooling methods is carried out. Modeling is done with a lumped parameter thermal networks (LPTN). The paper concludes demonstrating the advantages and disadvantages of the different cooling concepts based on the collection of modeling data.

“…The improved thermal network model can derive the motor's temperature field distribution faster without complete motor parameters [9][10][11]. Only axial and radial heat transfer is generally concerned in the temperature field analysis of permanent magnet synchronous motors for electric vehicles [12].…”

A hybrid heat-pipe cooling structure for the permanent magnet synchronous motor for electric vehicles was analyzed in this paper to effectively equalize the axial temperature rise and reduce the average temperature of each heat-generating component in the motor. A temperature field calculation method for the hybrid heat-pipe cooling permanent magnet synchronous motor based on an equivalent thermal network method was proposed in this paper to save computing resources in temperature field analyses for hybrid heat-pipe cooling motors. The results were verified against the simulation results of the computational fluid dynamics method under three common operating conditions for electric vehicles. The error was proven to be within 5%. The calculation time of the proposed method was compared with the computational fluid dynamics method, which demonstrated that the calculation time of the proposed method was within 194 s.
