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.

Abstract: The invention relates to a battery unit (10) for use in a vehicle electrical system (50) of a motor vehicle, comprising a battery module (20) for producing a first voltage between a positive pole (12) and a negative pole (11), a battery sensor (52), which is electrically connected to the negative pole (11), and a control element (30), which has a first terminal (31) electrically connected to the positive pole (12) and which comprises a DC-to-DC converter (35). The DC-to-DC converter (35) generates a second voltage between a second terminal (32) of the control element (30) and the negative pole (11) in dependence on at least one state variable of the battery module (20), and the battery sensor (52) is electrically connected to the second terminal (32), the battery sensor (52) having means for measuring the second voltage and means for measuring a current flowing through the negative pole (11), or the battery sensor (52) comprising a current sensor and being connected to a control unit which has means for measuring the second voltage and/or means for determining a current flowing through the negative pole (11). The invention also relates to a method for operating a battery unit (10) according to the invention in a vehicle electrical system (50) of a motor vehicle, wherein the second voltage is generated by the DC-to-DC converter (35) of the control element (30) in dependence on the state variable of the battery module (20).
