Abstract: The invention relates to a method for connecting one or more electric battery units to an electrical system. The method comprises: maintaining a system short-circuit which short-circuits the electrical system; while the system short-circuit is maintained, electrically connecting a first electric battery unit, which is locally short-circuited by a local short-circuit, to the electrical system so as to include the first electric battery unit in the electrical system; and while the system short-circuit is maintained, removing the local short-circuit of the first electric battery unit, whereupon the first electric battery unit is short-circuited by the system short-circuit of the electrical system. The method may be performed as a part of an electrical system installation procedure in for example a hybrid or electric vehicle and allows the electric battery units to be connected to the electrical system in a safe way.
