摘要
讨论了电池剩余放电时间问题。应用多项式拟合得到放电曲线通用模型,并通过MRE对模型精度进行了评估;对电池的衰减状态进行了回归分析,计算结果表明,误差满足精度要求。因此,模型可靠,可推广应用于各行各业的电池供电时长研究中。
The problem of battery residual discharge time is discussed. The model of the discharge curve is obtained by using the polynomial fitting,and the model accuracy is evaluated by MRE. The decay state of the battery is analyzed by regression. The results show that the errors meet with the request to precision. Therefore,the model is reliable,and it can be applied In all kinds of battery-powered long study.
