摘要
针对目前多数太阳能控制器对蓄电池充电控制不合理、保护不完善、储能能力低、使用寿命缩短等问题,设计了一种PWM控制、STC89C52和多阶段充电方法结合控制的太阳能供电系统。系统以STC89C52为核心控制器,实时检测太阳能电压和蓄电池电压,判断出蓄电池采用何种模式充电,并应用PWM控制策略实现太阳能与电能之间的最大功率转换,以提高蓄电池的充电能力、充电效率和使用寿命。通过实际应用,验证了该系统具有稳定性好、储能效率高、通用性强等优点。
Aiming at the control is not unreasonable of most batterys chargged by solar controllers in current,and the protection is not perfect.It is caused some problems,such as the battery has low energy storage capacity and reduced battery service life.A solar power system is designed that is realized by use PWM,STC89C52 and multi-stage charging method.STC89C52 is used as the core controller in the system,the solar voltage and battery voltage are detected real-timely,to judge out which charging mode is adopted by battery.,and the maximum power conversion between solar energy and electrical energy is realized by use PWM control method,so that the charging capability,the charge efficiency and the service life of batterys are improved.Practical application proves that this system has some advantages,such as good stability,high storage efficiency,strong currency and so on.
