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.

Method for controlling the temperature of a battery in a motor vehicle

The use of a heat-transfer composition including at least one refrigerant chosen from halogenated hydrocarbons, perhalogenated hydrocarbons, fluorinated ketones, fluorinated ethers and also combinations thereof, and at least one dielectric fluid, for cooling a battery of an item of equipment, such as an electric or hybrid vehicle, the heat-transfer composition having a volume resistivity of greater than or equal to 106 Ω·cm at 25° C.
