摘要
本文设计了一种高效率、高精度、低成本的双向Dc．DC锂电池充放电系统。该系统主要通过改变单片机输出信号的占空比来控制双向升降压电路工作，实现对锂电池的自动或手动的充放电管理。实验表明充放电电流在1—2A可调，步进精度0．8％，充放电效率可达90％．
A kind of high efficiency, high precision and low cost Lithium battery with two-way charging and ms- charging management system is designed. The system mainly controls two-way fluctuation voltage circuit through changing the duty ratios of microcontroUer output signal. This experiment indicates that the charge current can reg- ulate from 1A to 2A, and the step precision is zero point eight percent, the efficiency of charge and discharge can reach ninety percent.
