Use of an ester in a cooling composition The present invention relates to the use, for cooling a propulsion system of an electric or hydride vehicle, of a composition comprising at least one ester having a kinematic viscosity, measured at -25. ° C, less than or equal to 200 mm2 / s and an auto-ignition point greater than or equal to 350 ° C. It also relates to a composition capable of cooling a propulsion system, in particular the battery and / or the power electronics of an electric or hydride vehicle, said composition comprising (i) at least one ester exhibiting a kinematic viscosity, measured at -25 ° C, less than or equal to 200 mm2 / s and an auto-ignition point greater than or equal to 350 ° C and (ii) at least one additive chosen from among antioxidants, friction modifiers, detergents, antiwear additives, extreme pressure additives, dispersants, pour point improvers, antifoams and mixtures thereof.
