Beschreibung
Zusammenfassung:	A hybrid vehicle includes a thermal control system having a first high temperature cooling circuit, a second low temperature cooling circuit and a third cooling circuit for cooling/heating a battery pack. A system of valves is configured to connect the third circuit with the second circuit so as to create a loop consisting of a main portion of the third circuit and a main portion of the second circuit including the cooling portion of one or more electric motor assemblies of the hybrid vehicle, one or more additional components of the motor-vehicle, such as a turbocharger assembly and an intercooler assembly. In this operating condition, circulation of the liquid in the loop thus-formed can be activated by the pump of the third circuit and causes heating of the battery pack by the heat generated by the electric motor assemblies and, preferably, by the aforesaid additional components of the motor-vehicle.
