Beschreibung
Zusammenfassung:	A thermal regulation system (14) for an electric drive vehicle (1) has two loops (15, 16) provided with respective pumps (17,18) to circulate a heat transfer fluid, and with respective heat exchangers (12, 20) to cool the heat transfer fluid; a battery pack (2) is arranged along the first loop (15), whereas an electric drive electric/electronic unit (3) is arranged along the second loop (16), to be cooled; the system (14) has a valve (26) switchable between a first configuration, in which the two loops (15, 16) channel independent flows, and a second configuration, in which the two loops communicate to form a single cooling circuit; the electric drive electric/electronic unit (3) and the battery pack (2) are arranged in parallel in the single cooling circuit of the second configuration in order to be cooled by different heat transfer fluid flow rates.
