The invention relates to a method for estimating and/or predicting the maximum available capacity of a battery in a vehicle, and the method comprises the steps: a data collection stage: obtaining vehicle data of the vehicle at a plurality of moments, the vehicle data comprising battery data and mileage data; a data processing stage: based on the battery data, obtaining the maximum available capacity of the capacity parameter of the battery at the plurality of moments; and a data fitting stage: fitting the maximum available capacity of the battery along with the change process of the driving mileage of the vehicle. The invention also relates to a system for estimating and/or predicting a maximum available capacity of a battery in a vehicle. According to the invention, by using the real-time monitoring system, the maximum available capacity of the battery can be estimated and/or predicted under the condition that the specific parameters of the battery are not known in advance, so that the state of the battery is pre-warned and the recycling of the battery is pre-determined.

    本发明涉及一种用于在车辆中估计和/或预测电池的最大可用容量的方法,所述方法包括:数据收集阶段:获取所述车辆在多个时刻的车辆数据,所述车辆数据包括电池数据和里程数据;数据处理阶段:基于所述电池数据,获取所述电池的容量参量在所述多个时刻的最大可用容量;和数据拟合阶段:对所述电池的所述最大可用容量随着所述车辆的行驶里程的变化过程进行拟合。本发明还涉及一种用于在车辆中估计和/或预测电池的最大可用容量的系统。根据本发明,通过使用实时监控系统,能够在事先不了解电池的具体参数的情况下估计和/或预测电池的最大可用容量,从而对电池的状态进行预警以及预先决定电池的回收利用。
