A battery cell. The battery cell incluedes a first terminal contact and a second terminal contact, an energy storage unit, a first transistor, a sensor system that is set up to acquire a state parameter of the battery cell, and a control circuit. A first pole of the energy storage unit is coupled to the first terminal contact, and a second pole of the energy storage unit is coupled to the second terminal contact. The first transistor is connected between the first terminal contact and the second terminal contact in series with the energy storage unit. The he control circuit is set up to control a switching process of the first transistor, the control circuit controlling the first transistor based on the acquired state parameter in order to control a charge current or a discharge current of the energy storage unit.

Battery cell with an integrated control circuit

A method for operating at least one electrical component of a vehicle with the aid of a battery. At least two battery cells of the battery are electrically connected and thus added to the at least one component via at least one particular switching unit. The following steps for precharging a DC link of the vehicle is carried out: a) adding a first of the battery cells, b) incrementally adding at least a second of the battery cells, after a previous adding has taken place in each case.

Method for operating at least one electrical component of a vehicle

A MOS component includes a source area, a drain area, a body area, a channel area, and a gate element, the channel area and the gate element being electrically insulated with respect to one another by a total of at least three individual layers in the form of a first individual layer, a second individual layer, and a third individual layer. The second individual layer is designed in such a way that it may permanently store electric charges. The third individual layer, which is situated between the channel area and the second individual layer, has a greater equivalent oxide thickness than the first individual layer situated between the second individual layer and the gate element.

MOS component, electric circuit, and battery unit for a motor vehicle

A power module for an electric motor includes at least one semiconductor switch half bridge. The half bridge includes a high-side semiconductor switch and a low-side semiconductor switch. Each switch has a contact gap terminal formed by a surface region of the switch, in particular a flat surface region. The contact gap terminals, in particular a normal vector of the terminals, each points in a same direction. At least one electrically conductive layer is enclosed between the switches and electrically connects the contact gap terminal of the low-side semiconductor switch and the contact gap terminal of the high-side semiconductor switch of the half bridge to each other. Preferably an output terminal of the half bridge is formed by at least one electrically conductive layer.

Power module for an electric motor

A power module for an electric motor has at least one semiconductor switch half bridge with a high-side semiconductor switch and a low-side semiconductor switch. The semiconductor switches of the semiconductor switch half bridge have contact gap terminals which are each formed by a flat surface region of the semiconductor switch and which each point in the same direction. The high-side semiconductor switch and the low-side semiconductor switch enclose between them a circuit carrier that has at least two electrically conductive layers. A contact gap terminal of the low-side semiconductor switch and a contact gap terminal of the high-side semiconductor switch of the half bridge are electrically connected to each other by the circuit carrier.
