太阳能电动自行车的研制

Research on Solar Electrical Bicycle

在对太阳能电池组件特性进行研究的基础上,文章给出了整辆车的设计方案,采用了MICROCHIP公司的PIC16F877单片机实现智能的充放电控制,对蓄电池进行过充电保护,过放电保护,延长蓄电池的寿命。系统采用了最大功率点跟踪,采用霍耳传感器对无刷直流电机进行调速,实现低成本,高效率的控制方案,系统阐明硬件电路的设计及其控制的算法。

Based on the characteristics of the solar module . Article provides the design scheme of the whole bicycle. It uses Microchip microcomputer PIC16F877 to control the intelligent charge the storage of batteries. The controller has prolonged battery life by using overcharge protection and discharge protection. A maximum power point tracker （MPPT） has been implemented. This is achieved by using Hall sensor to regulate the brushless DC motor speed. It is proposed that this control project is low-cost and high efficiency. The last paragraph illuminates the design of the circuit and control algorithm.
