Abstract: A method for monitoring the state of health of at least one contactor in a battery pack, wherein the battery pack comprises at least one battery cell, a first interface line and a second interface line, wherein at least one switchable first contactor is arranged in the first interface line between the interface and the at least one battery cell, and at least one switchable second contactor is arranged in the second interface line between the interface and the at least one battery cell, comprising steps for the measurement of a first differential voltage across the open first contactor and/or the measurement of a second differential voltage across the open second contactor, and the monitoring of the state of health of the first contactor on the basis of the measured first differential voltage and/or determination of the state of health of the second contactor on the basis of the measured second differential voltage.

Abstract: The present invention relates to a control system for use in a bus system having at least two transmission lines, having a first control device which has a first termination path and a first terminating resistor connected to the first termination path, a second control device which has a second termination path and a second terminating resistor connected to the second termination path, a first connector which is adapted to connect the first control device to the transmission lines and therefore to integrate the first control device in the bus system, a second connector which is adapted to connect the second control device to the transmission lines and therefore to integrate the second control device in the bus system, wherein the first connector and the second connector are different to one another. The invention also relates to a connector for connecting a control device to transmission lines of a bus system.

Abstract: A battery module for constructing a battery system for a vehicle includes at least one battery cell and a battery management controller (BMC) with a battery management controller interface (BMCS). The battery management controller interface (BMCS) has at least two address contacts for allocating an address to the battery module, and the battery management controller (BMC) is designed and configured to detect the assignment of the address contacts and derive therefrom an address for the battery module.

Abstract: Battery system, preferably for a hybrid or electric vehicle, wherein the battery system comprises: one or more battery packs each having one or more cells which are electrically connected and configured to provide a voltage, preferably a high voltage, at a respective battery pack output; and an integration device electrically connected to the battery pack outputs and configured to receive and combine the power of the battery packs, thereby forming a sum power supplied to a sum voltage output of the integration device; where in the integration device comprises a filter device which is configured to protect the battery packs from interferences, for example interferences generated by an electrical component connected to the sum voltage output.
