The invention provides a heat preservation structure for a power battery of a new energy automobile. The heat preservation structure comprises: an upper heat preservation layer, which is arranged between a battery module and an upper cover plate; a water cooling mechanism, which is arranged below the battery module and is positioned between the battery module and a battery shell; and a heat preservation structure layer, which is arranged outside the battery shell and comprises a heat preservation material layer and a PP material layer, wherein the heat preservation material layer is arranged outside the battery shell, and the PP material layer is arranged outside the heat preservation material layer. Compared with a traditional heat preservation structure for the power battery, the heat preservation structure for the power battery of the new energy automobile in the invention has the advantages that the heat preservation structure layer is used for replacing an air heat preservation layer of a traditional power battery, heat dissipation of the power battery is reduced, heat preservation effect is improved, and the energy-saving effect of the new energy automobile is improved.

    本发明提供了一种新能源汽车动力电池保温结构,包括:上保温层,设置在电池模组与所述上盖板之间;水冷机构,设置在所述电池模组的下方,位于所述电池模组与所述电池壳体之间;以及保温结构层,设置在所述电池壳体外,所述保温结构层包括保温材料层以及PP材料层,所述保温材料层设置在所述电池壳体外,所述PP材料层设置在所述保温材料层外。本发明的一种新能源汽车动力电池保温结构,与传统动力电池保温结构相比,使用保温结构层替代传统电力电池的空气保温层,降低了动力电池的热耗散,保温效果获得提升,提高了新能源汽车的节能效果。
