太阳能蓄电池充放电控制器的设计

清洁能源的开发日益受到许多国家的重视,世界各地都在发展光伏发电,由于独立式发电系统中蓄电池的充放电比较频繁,为了延长蓄电池寿命、减少系统故障和提高系统稳定性以及减少发电运营成本,需要对蓄电池的充放电进行管理。本文设计了一种基于PWM控制的太阳能蓄电池充放电控制器,系统主要由单片机、电压采集、充电控制和放电控制等组成。

The development of clean energy has attracted more and more attention in many countries, and photovoltaic power generation is developing all over the world. Due to the frequent charging and discharging of batteries in independent power generation systems, in order to prolong the life of batteries, reduce system failures, improve system stability and reduce the cost of power generation operation, it is necessary to manage the charging and discharging of batteries. This paper designs a charge and discharge controller of solar battery based on PWM control. The system is mainly composed of single chip computer, voltage acquisition, charge control and discharge control.
