Abstract

A method for estimating a minimum continuous and transient supply voltage (U_{min_con}, U_{min_trans}) of a battery (2). The method comprises: performing first and second electrical load tests of the battery (2) while registering parameters characterising a discharge current profile and discharge voltage profile of the battery (2); 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 (U_{min_con}) using said continuous battery coefficient, and calculating a minimum transient supply voltage (U_{min_trans}) from the battery (2) using said transient battery coefficient.
