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.

A battery pack for a vehicle is provided. The battery pack comprises: at least one battery module including a plurality of secondary battery cells, a metal framework for supporting the at least one battery module, the framework including a plurality of slots extending from a bottom side to an opposing mounting side of the battery pack, and an insert tightly positioned within each slot, the insert being made of a similar material as the framework and including a through-hole adapted for accommodating a fixation element.

One or more systems, devices, and/or system-implemented methods are provided that can facilitate provision of varying AC output voltage or DC output voltage, including selectively separately providing a positive voltage output, a negative voltage output and no voltage output. A device can comprise a battery cell, and a controller connected to the battery cell and that varies output from the battery cell, wherein the controller is configured to cause the battery cell to selectively separately provide negative output voltage, positive output voltage and no output voltage. A method can comprise varying output polarity from a multi-cell battery cluster and selectively providing one or both of alternating current (AC) voltage output or direct current (DC) voltage output from the multi-cell battery cluster due to the varying of the output polarity.

An apparatus and a method for processing battery cell voltage data, which calculate a moving average by assigning a weight to one or more voltage data acquired from the battery cell and reflect the acquired voltage data to the calculated moving average and use the voltage data to rapidly follow a sudden change of the voltage data applied from the battery cell.
