COOLING CIRCUIT WITH COOLING FLUID FOR LITHIUM BATTERIES, AND A VEHICLE COMPRISING SAID COOLING CIRCUIT

A cooling circuit (4) with cooling liquid for lithiumion batteries comprising a battery pack (8) comprising a plurality of cells (16) electrically connected with each other, suitable for powering an electric machine for traction (12), said cells (16) being perimetrically delimited by external walls (20), at least one bag (24) containing cooling liquid associated in contact with said outer walls (20) of the cells (16). Advantageously, at least one bag (24) is made of deformable plastic material so as to be counter-shaped to said outer walls (20) to adhere perimetrally to said outer walls (20) and the circuit comprises means of forced circulation (27) of the cooling liquid through said at least one bag (24).
