文 章分析了光伏阵列输出能量特点和蓄电池充电特点，提出了一种新的控制方法，并

设计出基于AVR单片机的光伏系统充电控制器。试验证明该控制器在充分利用光伏阵列能量

同时能提高蓄电池充电效率，较理想地实现了对光伏系统中储能蓄电池的充电控制。-ATh isp apera nalyzesth ee nergyo utputc haracteristico fP Va rraya ndt hec hargea nd

discharge characteristic of batteries, and develops a new control method. A PV system charge eontroller

based on AVR singlechip is designed. Experiments prove that the controler takes full advantage

of PV array energy and imrpoves the batteries charge eficiency, which achieve the excelent

charge control of the energy storage battery in PV system.
