The spring contacts are divided into a first group and a second group. In a first state, the spring contacts of the first group are in contact with their associated contact areas and the spring contacts of the second groups rest on at least one stop and are not in contact with their associated contact areas. A trigger causes the spring contacts of the second group to overcome the at least one stop when a defined temperature is exceeded so as to come into contact with their associated contact areas in a second state.

Abstract: In a method for operating a hybrid vehicle, which includes an internal combustion engine and an electric machine as the propulsive drive, the electric machine operates in both motor and generator modes. Furthermore, there is an accumulator device, such as a capacitor assembly, for storing electric energy. The aim is to provide a method that guarantees an improved start-up operation of a hybrid motor vehicle in terms of fuel consumption and emission. This is achieved in that in the start-up operation the torque required on the basis of the request of the driver to drive the vehicle is divided between the internal combustion engine and the electric machine, as a function of the existing operating parameters of the vehicle.
