摘要
在光伏应用系统中,实现蓄电池高效、快速充电的有效方法是涓流预充电,先快速恒流充电再恒压充电,然后自动终止。根据Li-Ion和Li-Pol电池的充电特点,以BQ24085智能充电管理芯片为核心,设计了光伏智能充电系统。并通过样机试验,结果验证了该系统的可行性和实用性。本设计集成度和充电效率高、实现简单、工作可靠,适合多种型号电池的充电。
In photovoltaic application system, triclde-charge,constant current,constant voltage are applied to charge batteries effidendy and rapidly,and the process can come to an end automatically. Based on the charging characteristics of Li-Ion and Li-Pol batteries with different charged currents,a smart charge system has been designed with the single chip BQ24085 as its core. After the test of a sample,this system is feasible and practical. Its integration and charge efficiency are quite high and it can work reliably,so it is suitable to charge various batteries.
