Abstract: The present disclosure provides a battery pack including a housing, wherein the housing has a bottom portion, on which are disposed a first length side wall and a second length side wall that extend upward along a length direction of the bottom portion and are oppositely disposed, and a first width side wall and a second width side wall that extend upward along a width direction of the bottom portion and are oppositely disposed; the housing comprises a first step and a second step disposed at two ends of the first length side wall; the housing further comprises a first metal wiring terminal and a second metal wiring terminal, wherein the first metal wiring terminal and the second metal wiring terminal are disposed on the first step and the second step, respectively; a material for bearing the first metal wiring terminal and the second metal wiring terminal is a first plastic material, while other parts of the housing are made of a second plastic material, or most of other parts of the housing are made of the second plastic material. The two materials have different characteristics suitable for a requirement of the battery pack on the material.

Abstract: The present disclosure provides a battery pack including a housing, wherein the housing has a bottom portion and side walls extending upward around a periphery of the bottom portion; an upper portion opening is formed at top ends of the side walls extending upward; an upper cover is mounted on the upper portion opening of the housing; and the battery pack comprises: multiple flat battery cells; and a first end plate and a second end plate, wherein when the multiple battery cells are sequentially arranged and mounted into the housing from the upper portion opening, the first end plate and the second end plate are located at two end sides of the sequentially arranged multiple battery cells to laterally fix the sequentially arranged multiple battery cells. The two end plates may absorb deformation of the battery cell while expanding.
