Abstract
本研究設計混合電能車輛導向之機電整合混合散熱系統，利用機電整合來控制虛擬燃料電池與鋰電池在目標溫度區間(40℃/55℃)。本系統結構分加熱與散熱兩個子系統，加熱系統又分軟體與硬體，軟體部分透過Matlab/Simulink的車輛理論建模，以設計4kW輕型電動載具於追隨ECE40行車形態下得出廢熱功率之結果，並輸入於NI LabVIEW與可程式電源供應器中，方可控制硬體部分所模擬之雙電力源(鋰電池及燃料電池)之加熱器，提供即時熱功率負載以模擬實際車輛電池放熱變化。散熱系統又分軟體與硬體，軟體部分用於控制系統溫度，透過Matlab/Simulink及Stateflow來建立rule-base規則庫控制，輸入為雙加熱器之溫度訊號，輸出為控制三個硬體散熱元件包含：電子式比例閥、熱交換器風扇及冷卻水泵。並將規則庫控制燒錄於快速雛型控制器(Rapid-Prototyping Controller)以即時監控，使電池控制在目標溫度來充放電。而研究結果顯示在三種固定功率及ECE40行車型態變動功率之加熱情況，本系統可使燃料電池與鋰電池維持在最佳工作溫度。未來將進行實車驗證，了解混合動力散熱系統在實車上面之動力源冷卻表現、省能表現與整合狀況，因此須將整合後之冷卻系統應用在無人駕駛機車底盤動力計上進行實驗分析。
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.
