锂电池容量检测系统设计(含原理图,程序代码)(论文13000字,程序代码)
摘要：电动汽车的快速发展改变了锂电池的用途及领域，越来越多的汽车开始使用电能这种清洁能源，对于改善当今社会的雾霾环境具有很好的作用。锂电池已经越来越广泛地融入我们的生活。将锂电池的容量及性能状况进行实时检测，对安全合理地利用锂电池具有不可忽视的作用。本毕业设计着重研究可用于电动汽车中的锂电池的容量检测。通过MSP430对锂电池的开路电压进行采样，对其输出的电流进行电流转换并送入单片机进行采样，通过对测到的电压值运算来近似得到当前时刻锂电池的容量情况。最后将所有结果汇总到液晶屏幕上显示出来。

Design of Lithium Battery capacity detection system
Abstract: The rapid development of electric vehicles to change the use of lithium batteries and areas, more and more cars began to use electric energy this clean energy, to improve the environment of the fog and haze in today's society has a very good role. Lithium battery has become more and more widely used in our life. If the capacity of the lithium battery can be measured in real time, the performance status can be detected, which can not be ignored. The graduation design focuses on the capacity of lithium batteries in electric vehicles. By using MSP430 of lithium battery open circuit voltage is sampled, the output current of current converted and sent to the microcontroller to sample, by measuring the voltage value through the operation to approximate the capacity of the lithium battery. Finally, all the results are aggregated to the LCD screen displayed..
