摘 要随着全球变暖，能源一天天紧张和空气严重污染，电动车成为一种新的代步工具越来越受欢迎，以其绿色环保，交通便捷，价格低廉等优势占领各大市场，基本每家每户都有一辆电动车。电动车充电器作为衡量一部优劣电动车的重要依据，也是顾客考虑消费的重要参数之一，普通的电动车充电器寿命短，充电慢，发生大量的硫化反应，产生大量的析气。充电不均衡，因此让充电器的寿命大大简短，使电动车的电力越来越少，根本不足以满足我们的日常交通需求。所以，我们开始寻求一种电动车智能充电器，根据普通的电动车充电器的缺点进行了相应的改正，本次设计采用了两种芯片，一种是 AT89C52，另一种是 LM331，之后应用所学的单片机知识和 C语言知识共同设计出这款新型的智能充电器，采用电流型的控制方案，使其均衡充电，不影响充电器和电动车的寿命。利用创新的集成电路把控制芯片和大功率管集成在一起。主要用模拟智能充电器的各种输入信号完成该系统的硬件部分，C 语言用来编程完成其软件部分，总体来说，该设计是基于 C 语言和单片机的智能设计。关键词： AT89C52； LM331；单片机；C 语言；充电器；电池寿命ABSTRACTAs global warming and energy grew tense and serious air pollution, electric vehicles become a new kind of transportation has become more and more popular, with its green environmental protection, the transportation is convenient, the price is low wait for an advantage to capture each big market, every household has a basic electric vehicles.Electric car charger as a important basis of quality electric cars is also one of the important parameters of customers consider consumption, general electric car charger is shorter, charging slow, lots of vulcanization reaction, to produce large amounts of gas.Charge imbalance, so let the life of the charger short greatly, make the vehicle's less and less, to satisfy our daily traffic demand.So, we start to look for an intelligent electric car chargers, according to the shortcomings of the ordinary electric car charger for the corresponding correction, this...
