Model Development For Electric Vehicle Powertrain Thermal Management System

Abstract

The rapidly growing electric vehicle market has emerged as a key participant in the fight against environmental degradation and the oil shortage. Effective heat management systems are crucial as these cars are developed in order to guarantee battery safety, maximize energy efficiency, and increase vehicle lifespan. With today's technology, thermal energy in electric cars can be used and controlled more effectively. Temperature is to be optimized between components such as battery, charger, DC-DC converter, inverter, and electric motor. In this work, a comprehensive assessment of several thermal management methodologies at component level is to be done with a particular emphasis on the components using a variable fan and variable flow coolant pump. It is also proposed to add an AC chilling system to the battery and charger to safeguard the components if something happens beyond the temperature. Then the vehicle may be safe to run the components at its optimal efficiency and may reduce the range anxiety. The time and cost for designing these complicated systems can be significantly decreased with a suitable system simulation tool. A simulation model will be useful for assessing different control algorithms and should be able to effectively co-simulate with vehicle simulation programs. As MATLAB/Simulink dynamic system software performs effective simulations, it may be used to achieve the requirements. This work will be completed with the assistance of Gannet Engineering Private Limited, Bengaluru.
