摘　　要：为了实现对光伏发电照明系统能量的优化管理,提高能量利用效率,设计了基于可编程片上系统(PSoC)CY8C29466的光伏能量管理控制系统。系统对太阳能电池的功率输出采取了最大功率点跟踪控制(MPPT),一定程度上提高了光伏系统的输出效率。在蓄电池充放电过程中,采取了断开回路、连接负载的检测方法,实现了对蓄电池容量的准确检测,有效的防止了蓄电池过充、过放的发生,延长了其使用寿命。系统后期测试数据表明,基于PSoC的光伏能量管理系统可以对太阳能电池的输出和蓄电池的充放电进行有效控制,具有广泛的应用前景。In order to realize the optimization of photovoltaic lighting system for energy management and improve the efficiency of energy utilization, the photovoltaic energy management control system is designed base on programmable system on chip（ PSoC ）. The maximum power point tracking（MPPT） method was a- dopted to test and control power output of solar cell for the system, the power output of solar cell was im- proved in a certain extent. Due to the disconnect circuit and connected load method was adopted in the storage battery charging and discharging process, the system has realized the accurate tesing of battery ca- pacity, and effectively prevent the battery overcharge, discharge and prolong its service life. The results show that the output of the solar cells and battery charge and discharge process is effectively controlled by the photovoltaic energy management system based on PSoe, menwhile have a good application prospect.
