Abstract

The invention discloses a solid-state battery module, a battery pack and a design method of the battery pack, and belongs to the technical field of batteries. The solid-state battery module comprises a plurality of battery cells, wherein the plurality of battery cells are sequentially arranged along a first direction to form a battery cell row, an elastic medium is arranged between every two adjacent battery cells, and the two opposite side surfaces of the elastic medium are respectively bonded with the adjacent battery cells; a liquid cooling plate to which the bottoms of the plurality of battery cells are adhered; end plates, wherein the two opposite ends of the battery cell row are respectively provided with the end plates; and a strapping tape which is wound on the peripheries of the battery cell row and the end plates along the first direction, wherein a connecting piece can sequentially penetrate through the end plates and the liquid cooling plate and is fixed on a lower box body of the battery pack. According to the present invention, the parts of the solid-state battery module are reduced, the cost is reduced, and the mounting steps are simple.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a solid-state battery module, a battery pack and a design method of the battery pack. Background technique [0002] The energy density and cost of battery packs have always been important indicators that car companies pay attention to. The former affects the cruising range, while the latter affects the selling price. Lithium batteries have the characteristics of high energy density, large energy storage, long life, and wide operating temperature. They have been widely used in the field of electric vehicles, while solid-state batteries are safer to use because they have no electrolyte. [0003] In the prior art, in order to ensure the stability of the cells in the solid-state battery module, a metal frame is generally arranged in the lower box of the battery module to fix the cells. [0004] Using a metal frame to fix the battery cells increases the weight of the solid-state ba...
