Method for estimating ageing indicators of electric traction battery of e.g. electric car, involves providing battery health status indication to user, based on stored battery intensity and temperature values and ageing prediction model

摘要

The method involves continuously measuring intensity of current flowing in a battery and temperature of the battery (100). The intensity of current and the battery temperature are stored (102) in a usage memory (MU). An indication of health status of the battery after a predetermined utilization period of the vehicle for a predetermined property of the battery, is provided (106) to a user of the vehicle, where the indication is based on the stored values of the intensity and the temperature, and from a ageing prediction model (MV) of the battery installed within the vehicle.
