摘要
从保护铅酸蓄电池、提高充电效率的角度出发,分析了目前市场上主要充电方式的弊端,设计了一种正负脉冲型电动车智能充电器。系统采用PIC16F676单片机进行控制,将普通三段式充电方式中的恒压阶段变为正负脉冲充电方式,增加了涓流充电等功能,优化了定时和自断电电路,在延长蓄电池使用寿命、缩短充电时间方面有很好的效果。
This article, from the point of lead-acid battery protecting and charging efficiency improving, analyzes the malpractice of main charging means currently on the market, designs a positive and negative pulse type intelligent charger for electric vehicle. The system uses a PIC16F676 microcontroller to control the ordinary three-charge method in constant voltage stage into the positive and neg- ative pulse charging way. It increases the trickle charge function, optimizes the timing and power-off circuit, and it has very good resuits in prolonging service life of accumulator and shortening the charging time. The system use PIC16F676 MCU control, general three stage charging mode of constant phase into positive and negative pulse charging method.
