摘要

本研究主要為針對一部校園導覽車設計一套鋅空氣電池暨鋰電池雙電式混合動力模組。在此一能源模組當中，鋅空氣電池與鋰電池是以並聯的方式連接在馬達的驅動器上，此外，鋅空氣電池亦可透過另外一個DC/DC的充電器來對鋰電池充電。當鋅空氣電池與鋰電池同時對馬達放電時，本研究透過對鋅空氣電池輸出端連接的IGBT進行PWM的開度控制，來進行鋅空氣電池與鋰電池對馬達輸出功率的分配控制。在本研究當中，鋅空氣電池輸出端IGBT的開度以與駕駛者踏板角度等比例的方式進行控制。當停車時，則視鋰電池的殘電量來控制鋅空氣電池對鋰電池的充電，當鋰電池殘電量過低時，則進行定電流充電，當殘電量超過設定的門檻時，則以定電壓的模式進行充電，目的在盡量維持鋰電池的殘電量，以延長鋰電池壽命。此外，充電的方式以PWM的方式進行，來降低對於電池的破壞。本研究同時建立一套對應此一車輛的動態模擬程式以便觀察不同動態變數的變化情形，針對所建立的動態模擬程式則進行與實車測試之比對，以驗證其模擬之正確性。

The purpose of this research is to develop of a Zinc air battery and Li battery dual cell module for a campus tour car. In the energy module, Zinc-air battery and Li battery are connected in parallel to the motor. In addition, Zinc-air battery is also connected to the Li battery through a DC / DC charger such that the Zinc air battery can charge the Li battery directly. Furthermore, an IGBT is connected to the Zinc-air battery, and the power out between Zinc-air battery and Li battery is controlled through PWM duty control of the IGBT. On the other hand, to keep the Li battery at a longer life cycle, an energy management control law is established to control the energy output between the Zinc air battery and Li battery and the goal of the control law is to keep the State Of Charge (SOC) of Li battery at a certain level. In the energy management control law, there are two different modes. When the vehicle is stopped, a charging mode is activated and the power flow from the Zinc air battery to charge the Li battery. In the charging mode, if the SOC of Li is under a threshold, a constant current charging is activated. On the other hand, if the Li battery SOC exceeds the threshold, a constant voltage charging is activated. When the vehicle starts to move, the Zinc air battery output is controlled proportionally to the depth of the driver pedaling. Besides the development of the energy module, this research also establishes a simulation code for the vehicle dynamics simulation to observe the characteristics of the dynamic variables variations. This simulation code is validated through comparison with the vehicle dynamics testing data.
