1. A control unit (13) for a vehicular battery pack (3) comprising at least one module (12) provided with a plurality of electrochemical (C, C′, C″) cells supported by a support structure (15) of the vehicular battery pack (3), the control unit (13) being installable on board the support structure (15) of the battery pack and comprising:
a planar support substrate (37) made of an at least partially insulating material;
a plurality of sensor elements (14) configured to control the operating parameters of the electrochemical cells (C, C′, C″) of the module (12);
wherein at least part of the sensor elements (14) are arranged, on an upper face of the planar support substrate (37) of support, in two single rows so as to be positioned, each, once the unit is installed on board the vehicular battery pack (3), at a respective terminal pole (TT′, TT″) of each electrochemical cell;
wherein the sensor elements (14) comprise at least one voltage sensing device, which comprises at least two elastically conductive and deformable contact elements (39) arranged on a lower face of the planar support substrate (37) opposite the upper face, which is configured to be, in use, elastically compressed between the lower face of the planar support substrate (37) and the respective terminal pole (TT′, TT″), contacting the same at at least one point; and
wherein each of the plurality of sensor elements (14) further comprise a temperature sensor (TS) configured to detect a temperature at a respective terminal pole (TT′, TT″), each respective temperature sensor positioned on the lower face of the planar support substrate (37) between two deformable contact elements (39), the temperature sensor (TS) comprising an infrared sensor configured to emit a respective infrared light beam (41), the respective two deformable contact elements (39) being deformed to diverge from the planar support substrate (37) in opposite directions of the infrared light beam (41).
