A method for the switched division of a high-voltage battery of a vehicle, which, for the purpose of charging the high-voltage battery, is connected to a charging column supplying a charging voltage of a specific voltage level, wherein the voltage level of the high-voltage battery results from a number M of series-connected modules of the same rated voltage, wherein the voltage level of the high-voltage battery corresponds to an integer multiple N of the voltage level of the charging voltage of the charging column, wherein the high-voltage battery is subdivided into N parallel-interconnected segments consisting of an equal number of modules by means of a first switch position of a number of power semiconductors.

High-voltage battery division for charging column connection

A contact rail device for an at least partly electrically driven motor vehicle. The contact rail device comprises at least one busbar for electrical contact-connection of an electric machine to a supply device for the electric machine In this case, the busbar comprises at least one compensation bow for compensation of temperature-dependent changes in length.

Contact rail device for an at least partly electrically driven motor vehicle

A motor vehicle has a high-voltage battery and two separate electric machines. Each electric machine is associated with a power electronics unit, and each power electronics unit has a DC-to-DC converter. Each DC-to-DC converter is designed to reduce a high voltage of the high-voltage battery to a predetermined voltage. The two DC-to-DC converters of the two power electronics units are connected electrically in parallel and are set to different voltage values.

Method and arrangement for providing an electrical power for an on-board power supply system of a motor vehicle

An electric connecting module () for an electric component () of a motor vehicle () has a connecting section () with at least two electrical contacts (). A connecting housing () has a connecting opening that can be connected to the connecting section (). The connecting housing () has at least one cable opening () that opens laterally on the connecting housing () in relation to the connecting opening for routing electric connecting lines () through the connecting opening () and to connect them to the contacts (). The connecting housing () can be connected to the connecting section () in different rotational positions to route the connecting lines () in different directions in relation to the electric component ().
