Abstract: Disclosed is a battery cell including an electrode, a housing, a cell interior inside the housing, a temperature sensor, and a heat-conducting part which differs from the electrode, is entirely or partially disposed inside the housing of the battery cell, and is thermally connected to the temperature sensor.

Abstract: A drive train, which is configured to electrically operate a vehicle, includes an electric motor and a first and second energy store, each of which is electrically connected to the electric motor. The drive train also includes a first inverter and a second inverter, where the first inverter is provided between the first energy store and the electric motor, and where the second inverter is provided between the second energy store and the electric motor. The electric motor has four phases.

Abstract: An electric machine is provided having at least one first permanent magnet, at least one second permanent magnet, a first region, the temperature of which is in a first temperature range during operation, and a second region, the temperature of which is in a second temperature range during operation. The at least one second permanent magnet has a higher maximum working temperature than the first permanent magnet, wherein the maximum working temperature is below the temperature at which the magnetic field strength of the permanent magnet irreversibly decreases in dependence on temperature and because of a magnetic field applied externally to the permanent magnet from. The first permanent magnet is arranged in the first region and the second permanent magnet is arranged in the second region.

Abstract: A high-voltage battery for a motor vehicle has at least one battery cell for storing electrical energy and at least one temperature sensor, by which a temperature of the battery cell can be detected. The temperature sensor is arranged within the battery cell.
