中文摘要:

      新能源汽车将在交通领域中成为清洁能源替代的理想选择，使用LabVIEW虚拟仪器图形化开发环境作为软件平台，结合PC机和USB-6251数据采集卡等硬件，设计了一款新能源汽车充电检测系统。该系统能够实时检测充电电流、电压和荷电状态（State of Charge,SOC）等关键参数，并对充电过程进行数据记录和分析。该系统应用了反向传播（Back Propagation,BP）神经网络算法，以有效减少数据采集中的干扰并加速采集过程。以三元锂电池为研究对象，在不同温度和AC OFF状态下，根据算法输出曲线与表测曲线的相关波形和重要参数，对车辆的高低温快充测试进行分析。经试验初步验证，该检测系统输出的波形图和数据与充电桩显示的数据一致，显示出良好的实用性。
