Abstract: An emergency energy store for a vehicle. Multiple electrical energy storage devices may feed electrical power in parallel into an electrical power supply network of a vehicle with the aid of separate voltage converters in each case. An electromechanical brake booster for a vehicle, a braking and/or steering system for a vehicle, and a power supply system for a vehicle, are also provided. A manufacturing method for an emergency energy store of a vehicle is also provided.

Abstract: The invention relates to a method for determining a status of a thermal connection of at least one component within an electrical energy storage system to a heat source or heat sink, wherein the electrical energy storage system has at least one electrical energy storage unit, comprising the following steps: a) determining (S11) a temperature of the at least one component; b) determining (S12) a temperature of the heat source or heat sink, in particular a cooling plate; and c) determining (S13) the status of the thermal connection of the at least one component to the heat source or heat sink based on the temperature of the at least one component and the temperature of the heat source or heat sink. The invention also relates to a corresponding device and a corresponding electrical energy storage system.
