    Abstract: The invention relates to a method for controlling the temperature of a battery in an electric or hybrid motor vehicle by means of a system comprising a vapor compression circuit in which flows a first heat transfer composition comprising 2,3,3,3-tetrafluoropropene, and a secondary circuit in which flows a second heat transfer composition comprising 1-chloro-3,3,3-trifluoropropene that has a ratio of the Z form to the E form of less than or equal to 9, the method involving: —heat exchange between the battery and the second heat transfer composition; —heat exchange between the second heat transfer composition and the first heat transfer composition. The invention also relates to a system for carrying out said method.

    Abstract: A method of heat transfer by means of a composition containing hydrochlorofluoroolefins. A heat transfer method including, successively, a step of evaporation of a coolant fluid, a compression step, a step of condensation of said fluid at a temperature of greater than or equal to 70° C. and a step of expansion of said fluid, characterized in that that coolant fluid includes at least one hydrochlorofluoroolefin.
