Abstract

This application provides a battery module and a battery box. The battery module includes a housing with openings on both sides along its length; multiple battery cells spaced apart along the length of the battery module and located within the housing; a buffer assembly including a first buffer member located between two adjacent battery cells; and at least two module end plates, respectively disposed on openings on opposite sides of the housing, the module end plates being used to abut against the battery cells. This application offers high safety and effectively reduces heat transfer between the battery cells.
