The invention discloses a power battery capacity prediction method based on electric vehicle capacity mileage data, and the method comprises the steps: obtaining the mileage to be predicted of a target vehicle, and determining the historical mileage capacity data of the target vehicle and the overall mileage capacity data of a reference vehicle; determining a first capacity according to the mileage to be predicted and the overall mileage capacity data; based on a multi-output model, determining a second capacity according to the historical mileage capacity data, the to-be-predicted mileage and the overall mileage capacity data; and determining the predicted capacity corresponding to the mileage to be predicted according to the first capacity and the second capacity. Based on the second capacity obtained by the multi-output model, the internal correlation between the aging tracks of the power batteries in the reference vehicle and the target vehicle is established so as to predict the capacity of the target vehicle, the predicted capacity is obtained by combining the first capacity and the second capacity, and the first capacity is used for correcting the second capacity, so that the reliability of the predicted capacity is ensured; and the method is relatively high in universality.

    本申请公开了一种基于电动汽车容量里程数据的动力电池容量预测方法,包括步骤:获取目标车辆的待预测里程,并确定目标车辆的历史里程容量数据和参考车辆的整体里程容量数据;根据待预测里程以及整体里程容量数据,确定第一容量;基于多输出模型,根据历史里程容量数据、待预测里程以及整体里程容量数据,确定第二容量;根据第一容量和第二容量,确定待预测里程对应的预测容量。基于多输出模型得到的第二容量,建立参考车辆和目标车辆中动力电池老化轨迹之间的内在关联从而对目标车辆的容量进行预测,并结合第一容量和第二容量得到预测容量,利用第一容量对第二容量进行修正,保证了预测容量的可靠性,且具有较强的通用性。
