中文摘要
多電槽串聯之鉛酸電池充放電時,由於內部各電槽特性不一致,會引起電量不平衡的問題。本研究首先觀察鉛酸電池中串聯之個別電槽的充放電特性,發現電池在反覆充放電後,不平衡越加惡化。尤其,在放電時,可能導致某些狀況較差的電槽,被其餘串聯電槽逆向充電,形成負壓電槽。這不僅造成電量內耗,更會加速此電槽老化,進而導致無法復原的破壞,縮短整個電池的壽命。
為深入探討此一問題,本論文對單一電槽,分別以不同浮充電壓,以及不同截止電壓進行多次充放電實驗,分析浮充電壓充電與放電截止電壓對電槽壽命的影響。研究結果證實,電槽壽命受浮充電壓影響遠甚於放電截止電壓;而深度放電會造成電槽損壞,主要導因於長時間逆向充電。
Abstract
Due to the discrepancy among series-connected cells in a lead-acid battery pack, the restored capacities may not be the same during the charging/discharging processes. Through repeated charging and discharging, one can find that the unbalance of individual series-connected battery cell of lead-acid battery is getting worse, because those cells of poor state of charge may have negative voltage, causing reverse charging from the other cells. This abnormal operation results in not only more energy consumption, but also the acceleration of the battery-cell aging and the remarkable reduction of its lifetime.
For the purpose of investigating this problem, the operating characteristics of each cell is under study. The battery cells are purposely charged by different floating voltages and discharged by different cutoff voltages. The investigation results show that the lifecycles of battery cells are affected more significantly by floating charging voltage than by the discharging cutoff voltage. It is also found that a long time reverse charging has a destructive effect on the battery cells.
