  "textContent": "A method for operating a switching arrangement of an energy storage system, the energy storage system comprising a plurality of parallelly arranged battery packs and the switching arrangement comprising an associated contactor for each battery pack, the contactors being configured to connect and disconnect the battery packs relative a load by closing and opening, respectively. The method comprises disconnecting the battery packs from the load by means of the contactors such that the battery packs are disconnected in a sequence in which one contactor is opened last and thereby subject to increased disconnection wear, controlling the sequence in which the battery packs are disconnected in such a way that the increased disconnection wear is accounted for and used to distribute contactor wear among the contactors during subsequent disconnections of the battery packs from the load.",
