Abstract
A method for operating a switching arrangement of a rechargeable energy storage system, RESS. The RESS includes parallelly arranged battery packs and the switching arrangement comprising an associated contactor for each battery pack. The contactors are configured to connect and disconnect the battery packs relative a traction voltage bus by closing and opening, respectively, the traction voltage bus being connected to at least one load. The method includes providing a window of opportunity in which no request for powering the load by the battery packs, and no request for charging the battery packs, are allowed to be implemented, in the window of opportunity, preventing the contactors to open enabling equalization due to current transfer between the battery packs, measuring the current transfer between the battery packs, and in response to the measured current transfer, preventing the contactors to open and/or opening the contactors.
