Abstract

To provide a control unit (13) for a vehicle battery pack (3) comprising at least one module (12) provided with a plurality of electrochemical cells (C, C', C') carried on board a support structure (15) of the vehicle battery pack (3).SOLUTION: A control unit (13) includes a planar support substrate (37) made of an at least partially insulating material, and a plurality of sensor elements (14) configured to control the operating parameters of the electrochemical cells (C, C', C''') of a module (12). At least part of the sensor elements (14) are arranged in two rows so as to be each positioned, once the unit is installed on board the vehicle battery pack (3), in the area of a respective terminal poles (TT', TT'') of each electrochemical cell, the sensor elements (14) comprising at least one infrared temperature sensor (TS).SELECTED DRAWING: Figure 13
