A method is presented for controlling power output by a battery in a vehicle. The method includes: measuring voltage of the battery during a sequence of vehicle events to form a time series, where each vehicle event is powered by the battery; constructing an unknown fingerprint from the voltage measurements made during the sequence of vehicle events, where the unknown fingerprint is indicative of a sequence of vehicle events; comparing the unknown fingerprint to the at least one fingerprint; receiving a start signal, where the start signal is a request to start the engine of the vehicle; and, in response to receiving the start signal and based on the comparison of the unknown fingerprint to the at least one fingerprint, outputting electric power from the battery to an electric starter motor of the vehicle.
