Battery module disconnect arrangement

An arrangement for disconnecting at least one battery module of a plurality of battery modules in an automotive battery, the arrangement comprising:

• a device arranged to detect that at least one detected battery module is to be disconnected;
• a bypass switch arranged at each battery module, the bypass switch arranged at the at least one detected battery module being controllable to bypass the at least one detected battery module via a bypass path;
• and
• a disconnect switch arranged at each battery module, the disconnect switch arranged at the at least one detected battery module being controllable to disconnect the at least one detected battery module from remaining battery modules no earlier than simultaneously to bypassing of the at least one detected battery module such that the at least one detected battery module is at least one bypassed battery module.

An arrangement for disconnecting all battery modules of a plurality of battery modules in an automotive battery, the arrangement comprising:

• a device arranged to detect detected battery modules to be disconnected;
• a bypass switch arranged at the automotive battery controllable to bypass the battery modules via a bypass path;
• and
• a disconnect switch arranged at a location selected from a group consisting of each battery module and a main power delivery line, the disconnect switch arranged at the respective battery module being controllable to disconnect the respective battery module from a main power delivery line of the automotive battery no earlier than simultaneously to bypassing of the battery modules.
