US Patent 11437827 Control of a relatively low current fed to a battery pack

A method for controlling a current being fed to a battery pack including a plurality of battery cells connected in series and providing an output battery voltage includes the steps of: feeding a relatively low current through a resistor being arranged in series with the battery pack; and measuring the voltage across the resistor, thereby obtaining a value of the current. A system for controlling a current being fed to a battery pack is also provided.
