NOVELTY - The utility model claims a battery heating device based on graphene, comprising a shell with a containing space and a battery contained in the shell; the shell comprises a shell body and a shell cover covered on the shell body; the inner wall of the shell body is provided with a heat insulating layer; the outer side of the heat insulating layer is orderly provided with a graphene heating film; a first heat-conducting silicon film, the heat-insulating layer is adhered to the inner wall of the shell body; the bottom of the first heat-conducting silicon film is adhered with the bottom of the shell body; the graphene heating film is installed on the gap between the first heat-conducting silicon film and the heat-insulating layer around the shell body. The utility model is provided with a graphene heating film between the battery pack and adjacent transversely arranged or longitudinally arranged batteries; the heating uniformity is good, and the inner wall of the shell body is provided with a heat insulation layer; the heat dissipation is little, the first heat conducting silicon film, the setting of the second heat conducting silicon film can better uniformly transfer the heat of the graphene heating film, realizing the uniform heating of the battery at the low temperature environment.
