BATTERY SYSTEM COMPRISING CYLINDRICAL CELLS AND A TEMPERATURE SENSOR AND METHOD OF INSTALLING THE SAME

The present disclosure refers to a battery system, comprising a battery pack (10) including a plurality of cylindrical battery cells (12) arranged in an array with clearances (14) between neighboring battery cells (12), an electrical conductor element (20) having a main portion (16) extending along a surface of the battery pack (10) and at least one branch portion (18) branching off of the main portion (16) and comprising at least one temperature sensor (22) for sensing the temperature of at least one of the battery cells (12), the branch portion (18) with the temperature sensor (22) extending into one of the clearances (14) between the battery cells (12), the battery system further comprising a pin element (24, 124) inserted into the same clearance (14) such that it presses the temperature sensor (22) against at least one of the battery cells (12).
