    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.

    Abstract: A method for starting a combustion engine (2) in a propulsion system (1) of a hybrid vehicle, the propulsion system includes a planetary gear having three components: a sun gear (10), a ring gear (11) and a planet wheel carrier (12). The output shaft (2a) of the combustion engine connected to a first component of the planetary gear, an input shaft (3a) of a gearbox (3) connected to a second component of the planetary gear and a rotor (9b) of an electric machine (9) connected to a third component of the gearbox. The vehicle is set in an initial position with a suitable gear engaged in the gearbox and with a brake acting on the input shaft of the gearbox. After the electric machine is controlled so that the ring gear is brought into a negative rotation speed (n3) and the output shaft (2a) of the combustion engine is, via the sun gear, brought to rotate with a positive rotation speed (n1) so that the combustion engine may be started.

    Abstract: The invention relates to a method for propelling a vehicle comprising a first power source being an internal combustion engine and a second power source comprising at least one electrical machine. The vehicle is configured to be selectively driven according to a first mode and a second mode, wherein said second mode is prioritized more in relation to fuel efficiency of said vehicle than said first mode. When a maximum power for propelling said vehicle is requested, power delivered by said first power source and said second power source is controlled such that the total power delivered by said first and said second power source exceeds the maximum deliverable power of said first power source. The total power delivered by said first and said second power source is allowed to exceed the maximum deliverable power of said first power source when said vehicle is driven according to said second mode.
