Abstract: An apparatus for the charging of an electric battery unit of a vehicle, wherein the apparatus comprises an interface for connecting the battery unit to one or more of: a first electrical contact element of a pantograph and a second electrical contact element of the pantograph. The interface comprises one or more connectors. The connector comprises first and second electrically conductive members. The first electrically conductive member comprises a longitudinal side for electrical contact with one of the first and second electrical contact elements while the second electrically conductive member comprises a longitudinal side for electrical contact with the other one of the first and second electrical contact elements. The first and second electrically conductive members are spaced apart from one another. The connector comprises one holder for holding the first and second electrically conductive members, the holder being attachable to the vehicle. A vehicle including such an apparatus.

Abstract: Arrangement for damping of a piston movement in a compressed air cylinder (10; 20), which arrangement includes a compressed air cylinder (10; 20), a valve device, a compressed air device, and a control unit. The control unit controls valve devices such that the movement of the piston is damped before the piston reaches the casing of the compressed air cylinder. A method for control of the arrangement is disclosed.
