| 摘要: | 目前所發展電動載具的最大考驗為續航力問題，其關鍵在於高性能的儲能系統(電池組)。當今電動載具的設計概念，係延續傳統汽油動力引擎車輛的概念發展﹐以馬達替換引擎及以一個電池組替代油箱。因此﹐電池在同一時間內僅能選擇做充電或放電，難以針對電池管理最佳化設計著墨以提高電池的效能。為了提昇電動載具的續航力﹐本計劃提出創新又可行的做法 -- 智慧型多輸入多輸出分散式電池管理系統。即在同一時間內﹐電池組內之部分電池提供動能使電動載具運行﹐部分電池利用能量採集的充電。能量採集技術如採集行駛中之能量，例如剎車時所產生之回充能量、滑行行駛狀態所產生之能量、及沙灘車之振動能量的回收等,及太陽能、再生能源、燃料能源等。電動載具係由電池以直流方式藉電力線傳輸來提供運行之能量。直流電力線亦可做為電池管理系統之通訊/控制網路的匯流排﹐整合電力線及通訊控制的迴授訊號，降低控制線與介面的數量，大幅的降低汽車的成本。本計劃著重於以直流電力線方式為電池管理系統的控制網路。完成本計劃後﹐即可整合於植基於直流電力線通訊網路之電動載具。 Long endurance is one of the major measurements of today’s development of electric vehicles (EVs). The key is the performance of its energy storage systems, or battery units. The development concept of today’s EVs came from the traditional gasoline vehicles, where the EV motor(s) replaces the engine and a big battery unit substitutes the gasoline tank. As a result, the battery set has only one choice, i.e., battery charge or discharge, at a time. It would be rather difficult to develop battery management system (BMS) to provide optimal solution and to improve the battery’s efficiency. In order to achieve long endurance of EVs, it is proposed a smart distributed multiple-inputs and multiple-outputs BMS (MIMO-BMS). The proposed MIMO-BMS allows partial battery units are discharged, while the other units are simultaneously charges from energy harvesting. Note that the energy harvesting is a process by which is derived from external sources (e.g., solar power, thermal energy, wind energy, salinity gradients, and kinetic energy), captured, and stored. Since the energy of the EVs comes from the battery set in term of direct current (DC) and provides some components of the EVs thru the power line, the power line can also be used as the communication and control buses. In other words, the power line can be integrated and utilized to deliver the power, communication, and control signals. The integration can significantly reduce the numbers of interfaces/gateways of the controlled buses, providing a cost down solution. Therefore, the emphasis of this project is placed on the development of the MIMO-BMS over the DC power-line control bus. The developed results from this project can be readily extended to the EVs based on the DC power-line control bus. 研究期間：10005 ~ 10104 |
