Abstract: A system for coupling an energy store to a normal coupling unit meant for a taller energy store includes an energy store, a normal coupling unit, and an adapter. A coupling profile of the energy store is defined by a recess in the upper side of the energy store and a coupling cam having an engagement surface. The adapter has a fastening portion receivable within the coupling profile of the energy store and is detachably fastened to the energy store. The adapter also has a coupling portion having a coupling structure with a coupling surface and a curved surface. A pivotable lever of the normal coupling unit engages on the coupling surface of the adapter and is guided on the curved surface of the adapter such that pivoting of the lever is transformed into translational movement of the energy store towards the normal coupling unit.

Abstract: An arrangement for establishing an electrical connection of a stored energy source (14) to electrical components of a two wheeled vehicle includes a coupling unit (12) to which the stored energy source is detachably fastened and a connection module (26) for electrically connecting components of the two-wheeled vehicle. The connection module (26) is detachably connected to the coupling unit (12). The connection module (26) has a plug interface (24) to an electrical plug connector (44) of the stored energy source (14). The connection module (26) has at least one connection interface (30) for coupling terminal connectors (58) of components of the two-wheeled vehicle to the connection module (26) and for supplying the components of the two-wheeled vehicle with energy from the stored energy source (14).

Abstract: The invention relates to an arrangement for fixing an energy storage device (101) on a vehicle frame, the arrangement having a guide groove (203) and one or more sliding blocks (201) which are designed to interlockingly engage into the guide groove (203). The arrangement has one or more holding means (205) which are at least partially arranged in the guide groove (203) and are each elastically deformable due to contact with a sliding block (201).

Abstract: An arrangement for fixing an energy storage device on a vehicle frame includes a base module and a lever pivotably mounted to the base module. The lever is pivotable relative to the base module into an engagement position, and further pivotable from the engagement position into an end position. The lever is configured to engage an energy storage device when brought into the engagement position. Additionally, the lever forms part of a cam mechanism such that pivoting of the lever from the engagement position towards the end position is configured to cause displacement of an energy storage device towards the base module.
