NOVELTY - The utility model claims a graphene film assembly for pre-heating battery of electric automobile, relating to the power battery pack preheating technology field. Including: graphene heating layer, a heat conducting mechanism, provided with two groups, each group of heat conducting mechanism are symmetrically set on the two sides graphene the heating layer, the first PET film layer is provided with two, each first PET film layer are set on the heat conducting mechanism, a heat insulating mechanism, set on the heat conducting mechanism. The utility model is used for electric automobile battery pre-heating graphene film component, through the glue layer, the film graphene can be tightly jointed with the electric automobile battery, avoids the graphene between the film component and the electric automobile battery, reduces the transmission of the heat energy, so as to affect the graphene-heating effect of the film component, The utility model is used for electric automobile battery pre-heating graphene the film assembly, through aluminium silicate fibre paper and aerogel felt, can reduce the graphene loss of the film assembly, preventing electric automobile battery pre-heating time is too long, improving the preheating effect of graphene film component.
