Abstract
The present invention relates to a method and arrangement for classifying a voltage fault condition of a battery comprising a plurality of cells for a vehicle. The method comprises detecting a cell voltage of one of the cells (S), determining that the cell has a voltage fault condition based on the cell voltage being outside a predetermined voltage range (S), classifying the severity of the voltage fault condition based on the cell voltage (S), performing at least one diagnostic test routine, based on the severity of the voltage fault condition, to provide a cause for the voltage fault condition (S), selecting and adapting a battery operation condition, based on the severity of the voltage fault condition and the cause, such that the battery is enabled to continue to operate the vehicle (S).
