摘  要:分析了蓄电池剩余容量预测技术的难点,针对蓄电池剩余容量存在随温度、电解液浓度等外部条件而产生周期性变化的特点,提出了新陈代谢GM(1,1)预测模型。通过将新信息GM(1,1)模型和新陈代谢GM(1,1)模型对比,分析误差,并通过计算机实际模拟证明,新陈代谢GM(1,1)预测模型能够明显地提高预测精度,增加预测可靠程度,从而实现蓄电池剩余容量的精确预测。The difficulties to predict the residual capacity of battery were analyzed, then based on the peculiarity that battery's residual capacity changed cyclically with external factors, such as temperature, electrolyte density, etc., the metabolic GM (1,1) forecasting model was proposed. By comparing new information GM(1,1) model with metabolic GM (1,1) model, the errors were analyzed. The computer modeling show that metabolic GM (1,1) forecasting model can significantly improve forecasting accuracy and reliability, thereby achieve accurate forecasting of battery residual capacity.
