Performance Analysis of Integrated Battery and Traction Motor Cooling Systems for Two-Wheeler Electric Vehicles Applications 2022-28-0413

The automotive industry is a gigantic industry as millions of vehicles are running on the road and it’s growing at a rapid rate. The emissions are causing various global problems such as global warming, green house effects, air pollutions etc. due to the use of fossil fuels in abundance. This drives to think for alternative solutions, which are eco-friendly and having less or no emissions. The electric vehicles (EVs) are the most reliable solution as it is having high performance and efficiency with zero emissions. The evolution of EVs has fuelled the two-wheeler EVs industry to flourish at a fast pace. Li-ion battery and traction motor are the most important components in two-wheeler EVs and the thermal management for battery is more important for higher efficiency with longer life and better reliability along with the traction motor to have long range and better durability.

This paper elaborates the radiator based thermal management solutions for the battery pack and the traction motor. It describes various technologies, which are being used for the thermal management of the battery pack and the traction motor. The cost and the packaging space are the bigger concerns for the OEMs (Original Equipment Manufactures) to not to go for heavier solutions, that’s why this paper discusses the integrated thermal management solutions, which is compact in size, light-weight and reliable for two-wheeler EVs for various vehicle-ranges. The liquid-based solutions have been taken into consideration to mitigate the thermal management issues in the battery pack and the traction motor in this paper. The recent incidents of the two-wheeler EVs catching fire on the road or during charging has put up the industry at the forefront to think for the reliable thermal management solutions, that’s why this research study has a very important role to play in eradicating the battery thermal issues as well as the traction motor thermal management issues.
