Method for detecting a faulty temperature sensor of a plurality of temperature sensors in a battery assembly for a vehicle

A non-transitory computer readable medium comprising instructions stored in a memory and executed by a processor to carry out steps of a method for detecting a faulty temperature sensor of a plurality of temperature sensors in a battery assembly for a vehicle, wherein each of the plurality of temperature sensors is arranged in an associated location, the steps comprising:

• obtaining a plurality of data items, wherein each data item is associated with a temperature sensor out of the plurality of temperature sensors and wherein each data item is indicative of a temperature and a location of the associated temperature sensor,
• comparing the data items with respect to the associated temperatures and/or the associated locations,
• determining, based on the comparing, one or more outlier data items out of the plurality of data items and inferring the one or more temperature sensors associated with the one or more outlier data items to be faulty, or
• determining, based on the comparing, an absence of outlier data items.

A battery assembly for a vehicle, the battery assembly comprising:

• a plurality of battery cells,
• a plurality of temperature sensors, wherein a singular temperature sensor is associated with at least some of the plurality of battery cells, and
• a data processing apparatus, wherein the plurality of temperature sensors are communicatively connected to the data processing apparatus, and wherein the data processor apparatus is operable for:
• obtaining a plurality of data items, wherein each data item is associated with a temperature sensor out of the plurality of temperature sensors and wherein each data item is indicative of a temperature and a location of the associated temperature sensor,
• comparing the data items with respect to the associated temperatures and/or the associated locations,
• determining, based on the comparing, one or more outlier data items out of the plurality of data items and inferring the one or more temperature sensors associated with the one or more outlier data items to be faulty, or
• determining, based on the comparing, an absence of outlier data items.
