NOVELTY - The protection unit has a plug pin (20) provided with a non-conducting protective cap (22). A cylindrical-shaped non-conducting shield (18) and a region of the plug pin are separated by a gap opening (24). The gap opening forms an air gap between the plug pin and the shield. The shield and the protective cap are made of a plastic material. The plug pin is axially arranged in the shield. The battery switching off unit (10) comprises plug contacts (12), which are attached on the plug pin. The plug contacts are provided with terminals for a vehicle drive and for connection of battery cells.    USE - Electric shock protection unit for current-conducting connection element of a battery i.e. lithium ion battery, that is connected to a drive system of a motor car (all claimed) e.g. hybrid and electrical motor cars. Can also be used for a stationary application i.e. wind turbine, and in field of consumer goods such as laptop or mobile phone.    ADVANTAGE - The plug pin is provided with the non-conducting protective cap, where the cylindrical-shaped non-conducting shield and a region of the plug pin are separated by the gap opening, thus enabling a safe, simple and precise electrical assembly or disassembly of the connection elements. The gap opening forms the air gap between the plug pin and the shield, thus preventing the contact between the plug pin and the shield. The gap opening is formed in a tight manner, so that a finger does not fit in the gap opening, thus preventing a contact with the electrically conductive body and an electric shock. The protection unit provides additional protection against contact of electrically insulating material and in the radial direction to the plug pin. The battery achieves high energy storage densities by utilizing lithium ion technology.
