摘　　要：随着科技的不断发展,能源与环境的矛盾日益严重,发展新能源供电技术成为解决能源问题的重要手段。具有MPPT功能的光伏路灯系统是一种新能源供电技术,白天通过太阳能电池板给蓄电池充电,夜晚通过蓄电池放电给LED照明灯提供能源。通过分析该系统的软硬件电路,研究MPPT电池的充电技术,并进行仿真和实验,最终验证了设计方案的正确性。With the continuous development of science and technology,the contradiction between energy and environment is becoming increasingly serious.The development of new energy supply technology is an important means to solve the energy problem.The photovoltaic street lamp system with MPPT function is a new energy supply technology,which is charged by solar panels in the daytime,and provides energy to LED lighting through battery discharge at night.Through the analysis of the software and hardware circuit of the system,the charging technology of MPPT battery is studied,and the simulation and experiment are carried out.Finally,the correctness of the design is verified.
