A battery system for an electric motor vehicle comprises first and second battery cartridges that are installed in corresponding first and second battery compartments of the electric motor vehicle. The first battery cartridge has a power connector port with at least one of a shape, size, configuration and orientation that is different than the corresponding power connector port of the second battery cartridge. The first and second battery compartments are physically spaced apart and electrically coupled together by a bridging power cable. The bridging power cable comprises first and second connector ends that extend respectively into the first and second battery compartments, and the first connector end mates more easily with the first power connector port than with the second power connector port, and the second connector end mates more easily with the second power connector port than with the first power connector port.

An interface assembly includes an interface housing including a receiving portion arranged inside an interface cavity of the interface housing, for receiving an electrical contact element. The interface housing further includes at least two latches and an electrical contact element for transferring electrical power. The electrical contact element includes a busbar portion and a plug-in portion. The busbar portion includes at least two latching noses. Each of the at least two latching noses is assigned to one of the at least two latches to block a release movement of the assigned latching nose upon mating of the electrical contact element and the interface housing.

A connection portion of a lead wire is close to a surface of a metal plate, held at an accurate position, and held while preventing the wire from being movable. A connection structure of the lead wire includes the metal plate, the lead wire connected to the surface of the metal plate, and a pair of holding protrusions. The holding protrusions sandwich at least two parts of the lead wire to dispose the lead wire at a fixed position. Each of the holding protrusions has a holding gap sandwiching and holding the press-fitted lead wire. A connection space of the lead wire and the metal plate is provided between the holding protrusions. The lead wire is held on the surface of the metal plate with the holding protrusions and is connected to the surface of the metal plate in the connection space.
