Zusammenfassung:	A method for estimating a minimum continuous and transient supply voltage of a battery. The method include: performing first and second electrical load tests of the battery while registering parameters characterizing a discharge current profile and discharge voltage profile of the battery; determining a value of a continuous battery coefficient and a transient battery coefficient based on said registered parameters; calculating an estimate of the minimum continuous supply voltage using said continuous battery coefficient, and calculating a minimum transient supply voltage from the battery using said transient battery coefficient.
