Summary:

Global emission norms are getting very strict due to combat the harmful pollutants from internal combustion engine. Hence internal combustion engine (ICE)-based agricultural tractors need to introduce complex after-treatment systems and fuel optimization to provide same or higher value to farmers as cost of these systems drive the overall cost of the product. Engineers around the world are building Electric vehicles to combat the problem and has range issues due to design constraints and Hybrid tractors have emerged as a promising intermittent solution. It helps in combining the advantages of respective ICE and electrification solutions while reducing overall vehicle emissions and enhances operational flexibility.This paper presents a modular thermal modes system developed for a hybrid electric tractor platform where a downsized diesel engine operates at optimal efficiency DC generator used to charge the battery and DC converter is used to charge the auxiliary battery. Battery which is used to turn powers three independent motors. Primary and Secondary drive cooling. To maintain optimal operating temperatures of engine, power electronics components (battery, inverter, and motors), a smart thermal control architecture is developed using a radiator-based liquid cooling system. Engine waste heating recovery used for battery pre-conditioning.The system is designed with the capability to cool, engine, battery and power electronics. This thermal management control strategy cooling system works based on coolant temperature, battery temperature and ambient condition, control valves and temperature sensor send request to the VCU. VCU monitor the temperature, voltage and current. It communicates with battery BMS and motor controller within the tractor. This paper outlines the system objectives, architecture, operational thermal modes, and the control logic that enables modular thermal response.Proper thermal logic to be developed for various operating states and operating environments. In the present study thermal management control strategy has been derived and explained in the technical paper
