基于单片机的多模式蓄电池充电电路设计

he paper presents a common rechargeable battery controlled by the software. It can transform the charging pattern according to the charging features in accordance with this charging mode. This design uses AT89C51 SCM chip controls the charging process, achieving A/D convert and show circuit. The battery voltage information can be detected by the external circuit to choose the correct charge mode, realizing the intelligent conversion mode of the trickle charge, the constant current charging, the constant voltage charging and the float charge.
