Abstract
The invention relates to a method for controlling the operation of an energy storage system () in a vehicle (), preferably an electric or hybrid electric vehicle, said energy storage system () comprising at least two battery packs () connected in parallel, said energy storage system () being adapted to provide at least a nominal power functionality for propulsion of said vehicle () using an allowed operating extent of all of said battery packs () of said energy storage system (), said allowed operating extent being a nominal working range of said battery packs (); said method comprising disconnecting at least one battery pack (); and setting said allowed operating extent for said remaining connected and active battery pack(s) () to an increased working range so as to enable said energy storage system () to provide said nominal power functionality to said vehicle (), the method further comprising monitoring at least one accumulated parameter indicative of the operation of said energy storage system () from the time of disconnection of said at least one battery pack (), and when said accumulated parameter reaches a threshold value, setting said allowed operating extent for said remaining battery pack(s) () to a decreased working range. The invention also relates to a control unit for controlling the operation of an energy storage system ().
