Magnetocaloric Cooling for Hybrid/Hydrogen and Electric Vehicle Cabin and Powertrain Components

The magnetocaloric cooling system is a promising alternative to traditional refrigeration systems that rely on the compression and expansion of harmful refrigerant gases. Utilizing the magnetocaloric effect, these systems can efficiently provide heating and cooling for a wide range of applications. One particularly significant application of this technology is in the air conditioning of electric vehicles and the thermal management of powertrain components. This study presents a Matlab Simulink model of the powertrain, alongside a COMSOL model of the permanent magnet, specifically designed for hybrid and electric car applications. The Matlab Simulink model simulates the dynamic behavior of the vehicle's powertrain, integrating the magnetocaloric cooling system to analyze its impact on performance and efficiency. This allows for a comprehensive evaluation of how the system can improve energy efficiency and thermal regulation in electric vehicles. Additionally, the COMSOL model focuses on the detailed behavior of the permanent magnet used in the magnetocaloric cooling system. This model provides insights into the magnetic field distribution and its interaction with the magnetocaloric materials, which are critical for optimizing the cooling cycle and enhancing overall system performance. To ensure the accuracy and reliability of the simulations, some interpolated experimental data were used. This data helps in refining the models, ensuring that they closely represent real-world scenarios and behaviors. By combining these advanced modeling techniques, the study aims to demonstrate the feasibility and benefits of implementing magnetocaloric cooling systems in electric and hybrid vehicles, potentially leading to more sustainable and efficient automotive thermal management solutions.
