Method, apparatus, and system for estimating battery degradation state during operation of electric or hybrid vehicle, and method for constructing model for estimation

摘要

A method for estimating a deterioration state of a battery of an electric or hybrid vehicle, wherein a) a time series of measured values of speed (v) or acceleration of the vehicle during operation of the battery, and at the same time, the battery Obtaining at least one time series of measured values (I, U, P) in an amount selected from the current or power supplied from and the voltage at the battery terminals; b) at least one Extracting the time-series interval corresponding to a speed or acceleration pattern satisfying a predetermined condition of: c) applying at least one continuous estimation or classification model to the time-series interval; Determining an estimate of the degradation state of the. Apparatus and system for performing such a method. How to build such a continuous estimation or classification model.
