电容降压脉冲式电动自行车快速充电器设计研究

Electric bicycle charger design of capacitor step-down pulse

电动自行车以灵活方便,经济实用的特点成为现代普通家庭的主要代步工具。但其续行能力差,电池易被充坏,充电慢的缺点为人们所诟病。该文介绍了一种基于电容降压,以PIC系列单片机为控制核心的放电式脉冲快速充电的方式。该方式不但充电速度快,普通家用电动自行车最多在2 h内充满,充电过程不会损伤电池,而且有修复电池的功能。

Electric bicycle with flexible and convenient,economical and practical features to become the main means of modern common household tools.But its continuatiou is poor,easily charge a bad battery, charging the shortcomings of slow attracted much criticism. This paper introduces a capacitor step--down,To PIC MCU to control the core of the fast charge mode. This method is not only fast charging,ordinary household electric bicycle filled up within 2 hours,the charging process will not damage the battery, and the function of the battery of a fix.
