摘要: 级电容是具有超大容量的新型储能元件，本文针对电动自行车需频繁充电和更换蓄电池的情况，采用超级电容作为电动自行车的动力源。首先对超级电容充电控制方案进行设计；重点在于充电控制电路的硬件设计，包括驱动电路、采样隔离电路以及信号调理等电路的设计。然后对充电控制器进行软件设计，采用先恒流充电后恒压充电的工作方式。最后对充电控制系统进行建模仿真，详细分析仿真结果，验证充电方式的合理性。

Abstract: Super capacitor is a novel storing energy element with large capacity. Aiming at the electric bicycle frequent charging and replacement battery, the paper adopts the super capacitor as the power source of the electric bicycle. First, the super capacitor charging control scheme is designed. The key is the hardware of charging control circuit, including the drive circuit, sampling isolation circuit and signal conditioning circuit design, etc. And then the software design of charge controller is designed, the paper adopts way of working of first constant current charging and then constant voltage charging. Finally, the simulation modeling of charging control system is designed, and the simulation results is detailed analyzed, which verify the rationality of the charging ways.
