1、 多功能充电器设计 I 多功能充电器设计 摘 要 电子技术的快速发展使得各种各样的电子产品都朝着便携式和小型轻量化的 方向发展,也使得更多的电气化产品采用基于电池的供电系统。目前,较多使用 的电池有镍镉、镍氢、铅蓄电池和锂电池。它们的各自特点决定了它们将在相当 长的时期内共存发展。由于不同类型电池的充电特性不同,通常对不同类型,甚 至不同电压、容量等级的电池使用不同的充电器,但这在实际使用中有诸多不 便。 本文介绍一种基于单片机的智能充电器的设计方法。该充电器可以实时采 集电池的电压和电流,并对充电过程进行智能控制。它可以自动计算电池的已充 电量和剩余的充电时间,也可以改变参数来适应各种不同电
2、池的充电。系统中的 管理电路还具有保护功能,可防止电池的过充和过放对电池造成损坏。 关键词: 科技/电子产品/充电器/多功能 多功能充电器设计 II Multifunctional charger design ABSTRACT The rapid development of electronic technology to make all kinds of electronic products are lightweight portable and small towards the direction of development, but also makes the more
3、electrification products based on battery power supply system. At present, more use of the battery is nickel cadmium, lead nimh, battery and lithium battery. Their respective characteristic decided they will coexist in a long time. Due to the different type battery charge character is different, usu
4、ally for different types, and even different voltage, capacity grades of battery charger, but it is different in practical use inconvenience. This paper introduces a kind of intelligent battery chargers based on single chip design method. The charger can collect real-time battery voltage, current, and to charge process of intelligent control. It can automatically calculate the battery charging and the remaining amount already charging time, also can change parameter to meet the
