Modelling Simulation and Experimental Verification of a Thermal Management System for the Integrated Energy / Power Module
This study developed an integrated thermal management system with the heat sources of fuel cells, lithium batteries, and an electric motor. Theoretical modeling and performance analysis were conducted through by the use of Matlab / Simulink platform and then the establishment of entity radiation platform. Through Matlab / Simulink platform and entity radiation platform the optimal temperatures of three power (energy) sources were controlled. The system contains two sets of electric-controlled proportional valve, a radiator fan and a cooling pump. The electric-controlled proportional valve is for regulating the coolant flows among the three sources. The coolant temperature was governed by a radiator fan where the fan speed was controlled. The cooling pump controlled the flow rate of the coolant through the input Voltage. For the system dynamics, the heat sources and thermal management system were modeled for a set of lumped-parameter dynamic equations. It was used to calculate the waste heat of three power sources by the step response test. For the fuzzy control rules, the three inputs were the temperatures of the heat sources, while the four outputs were the control Voltages of the two proportional valves, coolant pump and the radiator. These were used to have for the purpose of optimal temperature control. Entity radiation platform is divided into two subsystems of heating and cooling. The heating system basis simulates three power (energy) sources to have the waste heat quantity input in to being possible the formula programmable power supplies, which provides three power (energy) sources to need the heat energy immediately. The cooling system fragment sentence fuzzy control rules strategy in Rapid-Prototyping Controller. The input were the temperatures signal, changes of the control Voltages for the two proportional valves, the coolant pump and the radiator for the purpose of optimal temperature control. Results showed that because of the temperature feedback dropping Variance in the simulation cooling system and between the entity radiation platform, the radiation part opening detention creates the result partial differences. The experimental platform will be established to verify the simulation in the future. The real Vehicle Verification will be performed in the future to learn the cooling performance, spatial disposition, and endurance to experiment and analysis.
