Abstract
An electronic control device for controlling a vehicle battery pack comprises a non-programmable monitoring and actuation unit and a two-way serial communication interface. The non-programmable monitoring and actuation unit is electrically and operatively connectable to the battery pack and to each of the battery cells C to detect analog battery parameters P, including at least the magnitudes of battery voltage Vb and battery current Ib, in addition to temperature (Tc1, Tcn), current (Ic1, Icn) and voltage (Vc1, Vcn) of each battery cell C. The non-programmable monitoring and actuation unit generates monitoring signals Sm representative of the detected analog battery parameters P. The two-way serial communication interface is connected to the non-programmable monitoring and actuation unit to receive the monitoring signals Sm and to supply the aforesaid at least one command signal Sc.
