The invention relates to a method for managing a thermal management device (1) for an electric or hybrid motor vehicle, including a heat-transfer fluid circulation circuit (A) that includes: - a first loop (A1) comprising a first heat exchanger (5) configured to exchange heat with the batteries of the electric vehicle, and a cooler (4) connected jointly to a refrigerant circulation circuit (B); and - a second loop (A2) comprising a second heat exchanger (7) configured to exchange heat with the power electronics and/or motor of the electric vehicle, and a radiator (8), said first (A1) and second (A2) loops being configured to allow independent circulation of the heat-transfer fluid in each of the loops (A1, A2) and/or joint circulation, during operation, when the temperature Tbat_out of the heat-transfer fluid at the outlet of the first heat exchanger (5) is lower than a first temperature value T1, said first temperature value being lower than a maximum operating temperature Tmax_bat of the batteries, and when the temperature Tmel_out of the heat-transfer fluid at the outlet of the second heat exchanger (7) is higher than said first temperature value T1, such that the heat-transfer fluid of the second loop (A2) at the outlet of the second heat exchanger (7) is redirected towards the first loop (A1) and the first heat exchanger (5) so as to store heat in the batteries.
