A monitoring system for monitoring the temperature of a battery module having a plurality of battery cells, the monitoring system including an electric network including a plurality of thermistors, wherein each of the thermistors is thermally connected to a battery cell, a monitoring device that is adapted to measure a total resistance (R) of the electric network including the plurality of thermistors and is further adapted to generate a signal in case of detecting that the value of the total resistance (R) of the electric network traverses a predetermined threshold resistance value, wherein the monitoring system is adapted to determine a mean temperature (T) of the battery module independently from the measurement of the total resistance (R) of the electric network, and wherein the predetermined threshold resistance value is dependent on the mean temperature (T) of the battery module.

Temperature-dependent resistor network for temperature anomaly monitoring in a battery system

A battery system includes: a high voltage (HV) system having a plurality of connected rechargeable battery cells; a battery disconnecting unit (BDU) comprising a carrier plate, BDU relays configured to switchably open or close a HV line of the HV system, wherein the HV line is at least partially integrated into the carrier plate, and a BDU control unit configured to control the BDU relays; and a liquid cooling plate on a first side of the carrier plate.
