利用光伏電池給蓄電池充電

摘要：磷酸鋰鐵（LiFePO4）電池對比鈷基的Li離子/聚合物電池，具有安全性高、浮充電壓小、自放電率低、使用壽命長等一系列優點。本文所述LT36521C為可實現太陽能跟蹤、單塊式補償蓄電池充電的集成電路。當LT3652由單塊太陽能電池板供電時，其輸入調節回路能確保在最大輸出功率下工作，充分體現出這一新型太陽能充電器的優越特性。 敘詞：太陽電池陣列 光伏充電器 磷酸鋰鐵蓄電池 LT36521C Abstract：Compared with Cobalt-based Li-ion/polymer battery, LiFePO4 battery has various advantages, such as high safety, low float charge voltage, low self-discharge rate and long service life. LT36521C in this paper is an integrated circuit, being able to realize solar tracking and monolithic compensation battery charging.
