摘要
主要针对小功率太阳能光伏系统中铅酸蓄电池使用寿命短、充电效率低、功能单一等问题,在对常规充电方法的分析对比基础上,提出了采用快速PWM动态恒压充电法。很大程度上满足了小功率光伏系统对控制器的特殊要求。并根据这一理论设计了一种充电效率高、工作可靠、智能化的太阳能控制器,显著地延长了蓄电池的使用寿命,扩大了系统的控制功能。
In view of the short service life, charging inefficiency and single function of the lead - acid battery used in the miniwatt solar photovoltaic system,the fast PWM dynamic constant voltage charging is proposed to meet the special demand for the controller in the solar photovoltaic system. Therefore, the intelligent solar controller with high charging efficiency and reliability is designed, which obviously prolongs the service life of storage battery and strengthens the controlling function of the system.
