Title: A METHOD AND SYSTEM FOR CONTROLLING A CURRENT BEING FED TO A BATTERY PACK
Abstract:
The invention relates to a method for controlling a current being fed to a battery pack (4) comprising a plurality of battery cells (4a, 4b, 4c) connected in series and providing an output battery voltage (VB). The method comprises the steps of: feeding a relatively low current (i1) through a resistor (13) being arranged in series with said battery pack (4); and measuring the voltage across said resistor (13), thereby obtaining a value of said current (i1). The invention also relates to a system for controlling a current being fed to a battery pack (4).
