【摘要】 利用车上太阳能电池驱动换风扇并作为汽车电瓶辅助充电电源。由ATmega128为核心构成太阳能电池驱动换风扇和电瓶充电的控制系统。这个控制器测量车内外温度、太阳能电池电压、汽车电瓶电压,根据车内外温差自动控制换气风扇工作,根据太阳能电池输出状态和电瓶状态控制充电过程。最后,基于给出的软硬件设计构建了实验系统,进行了实验和总结。更多还原

【Abstract】 Solar cells are employed to drive the fan of car and as a supplementary charger of car battery.The ATmega128 is used as the controller of the control system for solar cells to drive fan and charge the car bettery.The controller measures both the temperatures inside and outside the car,the voltage of solar cells and the voltage of the car battery.It controls the work state of the fan and the bettary charging process according to the difference between the temperatures and the output state of bettary.Finally,based on expounded software and hardware design,an experiment system is build up.更多还原
