| description | The present invention relates to a composition for cooling a propulsion system of an electric or hybrid vehicle including at least one battery, comprising: (i) at least one base oil or at least one hydrocarbon-based fluid with a boiling point of greater than or equal to 50° C.; (ii) at least one fire retardant corresponding to formula (I)RF-L-RH (I)in which RF is a perfluorinated or partially fluorinated group, RH is a hydrocarbon-based group, and L is a linker; and (iii) at least one fluoro compound with a boiling point of between 50 and 250° C.The invention also relates to the use of at least one fluoro compound with a boiling point of between 50° C. and 250° C. for promoting the contact between a fire retardant corresponding to formula (I) and an element of a propulsion system of an electric or hybrid vehicle, when thermal runaway is observed, said fire retardant of formula (I) being formulated in a base oil, or a hydrocarbon-based fluid with a boiling point of greater than or equal to 50° C.Finally, the invention relates to a process for cooling and fire-protecting at least one battery of a propulsion system of an electric or hybrid vehicle, comprising at least one step of placing at least one battery in contact with a composition according to the invention. |
