At the same time, the investment and construction of large photovoltaic power stations all over the world also provide a new energy solution for human beings.. In addition, small off grid system because it has the characteristics of simple and flexible, it in the future will become another important field of photovoltaic power generation has a pivotal. Therefore, the study of off grid solar charging and discharging system is very necessary. In view of this, this paper designs the charging and discharging control of the solar energy acid battery based on SCM, and adopts the STC89C52, the battery is used for the lead-acid battery.. The main work of this paper is the research of PV array power and PV array combined with theory of lead-acid battery charging and discharging, thus making the battery safety and reasonable charge and discharge, so that the load can work stably and reliably. Keywords: single chip microcomputer UC3906, STC89C52, lead acid battery, battery charge and discharge control system. 目录 1 引言 1 1.1 课题研究背景及意义. 1 1.2光伏发电的发展历程与发展现状 3 1.3 本论文研究的主要内容 4 2 系统设计简介 5 2.1 单片机的简介及选择 5 2.2路灯系统简介 7 3 系统硬件电路设计 9 3.1 PV板特性与等效电路 9 3.2太阳能LED路灯控制器功能模块概述 13 3.2.1晶振电路 3 3.2.2 复位电路 13 3.3 电压采集模块 14 3.4 LCD1602显
