使用超級電容作為回收大型鋰離子電池電流調控模組之可行性評估

需汰換的電瓶或電瓶老化後，其充電能力儲備容量還是超過6成以上，若拿去回收真是太可惜了，若可集中善用，則是不可小看的一個資源，若是只覺得太佔空間，不美觀就仍意棄置，就會造成污染形成危害。每年遭汰換下來的電瓶為數不少，若能集中管理善用，則是一項資源，也能減少環境污染。本論文討論可重複使用的鋰離子電池的電儲存管理系統的控制。鋰離子電池(RLIB)與超級電容器（UC）並聯，通過DC / DC升壓轉換器連接到直流鏈路。該結構用來作增強系統峰值功率並減小鋰離子電池的放電深度。這裡使用的轉換器將超級電容器的電壓提升到鋰離子電池側的相同電壓準位，以便可拿來做調節它們的電流以滿足需求，特別是峰值功率。這裡，狀態空間平均方法來作EMS中以管理RLIB和UC之間的功率流。為了交替地管理需求負載電流，在UC，RLIB和dc-link之間配置開關S1和S2。 EMS用來作在這兩個交換機之間執行電流控制。進行模擬以確認所提出的EMS控制方案的有效性。此次採用汽車鋰離子電池（RLIB），為鋰離子電池(RLIB)的能源管理系統（EMS）。此次證明了新型能源管理系統(EMS)的有效性，並促進了鋰離子電池(RLIB)的應用。

After the battery needs to be replaced or the battery is aged, its charging capacity reserve capacity is still more than 60%. It is a pity to recycle it. If it can be used in a concentrated way, it is a resource that cannot be underestimated. If the space is not beautiful, it will still be abandoned, which will cause pollution and harm. Many batteries are replaced every year. If they can be managed and used in a centralized way, it is a resource and can reduce environmental pollution. This paper discusses the control of an electrical storage management system for reusable lithium-ion batteries. A lithium-ion battery (RLIB) is connected in parallel with a super capacitor (UC) and is connected to the DC link via a DC / DC boost converter. This structure is used to enhance the peak power of the system and reduce the discharge depth of the lithium-ion battery. The converter used here boosts the voltage of the supercapacitor to the same voltage level on the lithium-ion battery side, so that it can be used to adjust their current to meet demand, especially peak power. Here, the state space averaging method is used in EMS to manage the power flow between RLIB and UC. In order to manage the required load current alternately, switches S1 and S2 are configured between UC, RLIB and dc-link. EMS is used to perform current control between the two switches. Simulations were performed to confirm the effectiveness of the proposed EMS control scheme. This time, the automotive lithium-ion battery (RLIB) is adopted as the energy management system (EMS) of the lithium-ion battery (RLIB). This time proved the effectiveness of the new energy management system (EMS) and promoted the application of lithium ion batteries (RLIB).
