Abstract

The arrangement for disconnecting at least one of a plurality of battery modules in an automotive battery comprises a device arranged to detect that at least one battery module is to be disconnected, and a bypass switch arranged at each battery module, wherein the bypass switch arranged at the detected at least one battery module is controllable to bypass the at least one detected battery module via a bypass path. The arrangement further comprises a disconnect switch arranged at each battery module, wherein the disconnect switch arranged at the at least one bypassed battery module is controllable to disconnect the at least one detected battery module from remaining battery modules, either simultaneously as, or after, the bypassing of the detected battery module.
