通用型电动汽车蓄电池智能充电机设计

摘要

In order to adapt the fast, convenient and practical needs of charging, the design of a universal-intelligent charger for any kind of battery used for electric vehicle was introduced in this paper. To speed up the charging process, a 3-sectional variable pulse charging method with discharge of depolarization was offered, and the constant of each stage with Fuzzy adaptive PID control was kept. The hardware and software implementation scheme of the main circuit and the controller were presented at last.%为了适应方便、实用、快捷的充电需求,设计了一种适用于电动汽车用任意类型、任意状态蓄电池的通用型智能充电机,提出了一种带放电去极化的三段式可变脉冲充电方法来提高充电速度,并将模糊自适应PID算法引入各阶段的恒定控制中,最后给出了主电路和控制器的软硬件实现方案.
