Claim 1

1 . A battery system for a heavy-duty vehicle, comprising: at least one battery section which comprises a plurality of traction battery packs; a hold-and-release mechanism for connecting the battery section to the vehicle at a first point of connection and for enabling quick-release of the battery section from the vehicle in case of emergency; and a towing attachment element connected to the battery section and presenting a second point of connection for receiving a towing device for transporting the battery section away from the vehicle by towing, after the hold-and-release mechanism has released the battery section from the vehicle; wherein the first point of connection is different from the second point of connection; wherein the hold-and-release mechanism comprises a fastening element, which is configured to be broken when the hold-and-release mechanism is subjected to a force that exceeds a predetermined threshold force; wherein the hold-and-release mechanism comprises a mounting bracket connected to the fastening element, wherein the mounting bracket is configured to function as a lever when subjected to the force, resulting in breaking of the fastening element. at least one battery section which comprises a plurality of traction battery packs; a hold-and-release mechanism for connecting the battery section to the vehicle at a first point of connection and for enabling quick-release of the battery section from the vehicle in case of emergency; and a towing attachment element connected to the battery section and presenting a second point of connection for receiving a towing device for transporting the battery section away from the vehicle by towing, after the hold-and-release mechanism has released the battery section from the vehicle; wherein the first point of connection is different from the second point of connection; wherein the hold-and-release mechanism comprises a fastening element, which is configured to be broken when the hold-and-release mechanism is subjected to a force that exceeds a predetermined threshold force; wherein the hold-and-release mechanism comprises a mounting bracket connected to the fastening element, wherein the mounting bracket is configured to function as a lever when subjected to the force, resulting in breaking of the fastening element.
