A method for estimation of state of power for a battery for an electric vehicle is provided. The method comprising: measuring a temperature of the battery, and an output voltage from the battery; receiving a state of charge estimation based on a battery model; providing a SOP estimation model for the battery comprising the measured temperature and the measured output voltage. The method is characterized in that the SOP estimation model further comprises a parameter fault estimate for errors of the measured parameters and/or estimated parameters; and in that the method further comprises estimating the SOP based on the SOP estimation model for a battery.
