| Summary: | 碩士 === 國立臺灣師範大學 === 工業教育學系 === 103 === The research intergrated the electromechanical hybrid cooling system of hybrid electric vehicle, using electromechanical integration to control the virtual fuel cell and lithium batteries maintaining the target temperature range (40℃ / 55℃). The system structure is divided into two subsystems of heating and cooling, and heating system is divided into software and hardware. At software section, in order to get the thermal power, using vehicle theory on Matlab / Simulink to model, designing 4 kW light electric vehicle which follows the driving style of ECE40. And type in NI LabVIEW and programmable power supplies, in order to control the dual power source (lithium batteries and fuel cells) of heater which the hardware section simulate, providing instant thermal power load to simulate the actual vehicle battery exothermic change. Cooling system is divided into software and hardware, software section using for controlling the temperature of the system, through the Matlab / Simulink and Stateflow to establish rale-base rule base controlling. The input is the temperature signal of double heater, and the output is used to control the three hardware radiating element; electronic proportional valves, heat exchangers, fans and cooling pump. And burn the rule base control strategy in Rapid-Prototyping Controller for real-time monitoring, in order to control the battery at the target temperature for charging and discharging. The study shows that in the heating situation of the three fixed-power and the variation power case of ECE40, the system would let the fuel cell and lithium batteries maintain at the best working temperatures. The real vehicle verification will be performed in the future to learn the power source cooling performance of the hybrid cooling system, and integration situation of energy-saving performance. Therefore, the integrated cooling system should be applied on the unmanned motorcycle chassis dynamometer to experiment and analysis.
