A method and system for predicting the capacity of a vehicle battery using a cooperative model

摘要

A method comprising: collecting vehicle health status data from multiple vehicles (10) over a wireless network (52); using a processor to: identify a reference group among the plurality of vehicles (10); andreceiving the collected vehicle health status data from the reference group into a cooperative model for the vehicle health state, wherein the cooperative vehicle health state model is applicable to a current vehicle to predict a state of at least one component of the current vehicle, wherein the cooperative model is a battery age model for predicting the capacity is the battery (26) of the current vehicle having the form C (t) = C; where C (t) is the capacity of the battery (26) as a function of time t, C is the nominal capacity of the battery (26); t) is a weighted throughput of the battery (26) as a function of time, representing a standard throughput and being an adjustable parameter; and wherein values for the adjustable parameter c and the adjustable weights included in the weighted throughput Z (t) are obtained by analyzing the collected vehicle health status data.
