摘　　要：随着我国IT产业的快速发展,大量IT产品普及,市场上对锂电池的需求越来越大,而不同厂家的锂电池质量有别,需要对锂电池的容量进行检测。该文设计了一种基于AT89C52单片机为控制核心,由高精度A/D转换器TLC2543和D/A转换器MAX538等器件构成的锂电池容量检测系统.该系统的在测量过程能实现从恒流转为恒压充电的自然过渡,安全可靠,同时易于与计算机相连,构成一个智能的锂电池容量检测网络。With the rapid development of IT industry in our country, a great lot of IT products prevail in our daily life, and more and more lithium batteries are in demand. Obviously, it is necessary to test capacity of lithium battery. A lithium battery capacity testing system is dcsigncd in this paper, which is based on AT89C52, and using highly precise A/D convcrter TLC2543 and D/A converter MAX538. The system has a natural transition from constant current charge to constant voltage charge, and the system could easily connect with computers to constitute an intelligent network for testing capacity of lithium battery.
