【摘要】 该文对现行光伏系统中蓄电池充放电控制方案进行了分析。决定一个充电器性能的关键是其电压外环检测的精确度。普通的在线式电压检测方法由于无法完全满足蓄电池的充电特性,因此在提高蓄电池充电器的整体效能以及在提高蓄电池寿命方面造成瓶颈。针对电压环检测存在的问题,在本文中提出了一种新颖的检测方案——离线式检测,并用实验证明了新的离线式检测方案能进一步提高蓄电池的寿命。更多还原

【Abstract】 Two control methods of the charge and discharge of the lead-acid rechargeable battery in PV systems were introduced. Firstly on-line detecting method normally used was briefly introduced. A novel control method ( off-line detecting method was presented. Finally the advantages and disadvantages of both methods were compared, the results showed that the new method is feasible and superior, and the lifetime of the battery could be improved.更多还原
