A battery cell in the form of a round cell, having: at least one electrode element having an inner side and an outer side and at least one temperature control element, wherein the inner side of the at least one electrode element is spaced apart, at least in sections, from the outer side of the at least one electrode element by means of the temperature control element.

Battery cell

A battery for a motor vehicle has a battery wall that encloses a battery interior, an extinguishing agent reservoir situated in the battery interior, in which an extinguishing agent is accommodated, and at least one battery cell that is situated in the battery interior separate from the extinguishing agent. The extinguishing agent reservoir has a reservoir wall for retaining the extinguishing agent, and the reservoir wall has a first wall temperature at a normal operating temperature of the battery cell and has a second wall temperature at a limiting operating temperature of the battery cell. The reservoir wall is designed to maintain sealtightness for retaining the extinguishing agent at the first wall temperature and to be destroyed by the heat at the second wall temperature. The second wall temperature is greater than the first wall temperature, and the reservoir wall may be brought to the second wall temperature by means of the battery cell of the battery. A motor vehicle has an electric motor and a battery according to the invention.

Battery with extinguishing device, and motor vehicle

A semiconductor device comprising at least a semiconductor component, a heat sink, a connecting element and an electrical circuit connected to the heat sink in an electrically conductive manner; wherein the semiconductor component and the heat sink are arranged at a distance from one another and are electrically and thermally conductively connected via the connecting element, wherein an electrical current can be supplied to the electrical circuit via the heat sink.

Semiconductor device

The invention relates to an energy store (), in particular a high-voltage energy store, for motor vehicles, comprising a cell stack, which has a plurality of cell units () stacked one on the other and which has a plurality of cell holders () of plastic, each of which is arranged between two cell units () lying one on the other in order to hold and align the stacked cell units (), and comprising at least one flat heat sink (). According to the invention, the at least one heat sink () is arranged within the cell stack () on at least one of the cell units ().

Energy storage device for motor vehicles

In a method for cooling a traction battery of an electrically drivable vehicle, a refrigerant is used as cooling medium, and in a mass flow of specified magnitude is led along the traction battery through at least one channel. The at least one channel is in heat-conducting connection with the traction battery. It is proposed that an available cooling power (P) for cooling the traction battery is determined, wherein as a function of the available cooling power (P), the magnitude of the mass flow of the refrigerant is regulated in such a way that either no cooling power (P) is delivered to the traction battery, or the delivered cooling power (P) in each case assumes one of multiple cooling power stages (I, II) as a function of the available cooling power (P).
