1. A system for controlling temperature of at least one battery in a vehicle; said system comprising:
at least one battery configured for outputting electric power;
a thermal regulation circuit configured for being run through by a liquid and comprising an operative tract in thermal exchange relation with said at least one battery, so as to control the temperature thereof;
a refrigeration circuit configured for being run through by a fluid that is subjectable to a refrigeration cycle in a non-reversible manner; said refrigeration circuit comprising:
a condenser in thermal exchange relation with a heating tract of said thermal regulation circuit; and
an evaporator in thermal exchange relation with a cooling tract of said thermal regulation circuit; and
a valve assembly associated with the thermal regulation circuit and configured for selectively taking:
a heating configuration, in which said valve assembly defines, in the thermal regulation circuit, a closed heating path for the liquid between the operative tract and the heating tract;
a cooling configuration, in which said valve assembly defines, in the thermal regulation circuit, a closed cooling path for the liquid between the operative tract and the cooling tract;
wherein said thermal regulation circuit comprises a heating tract in thermal exchange relation with an air conditioning apparatus.
