Abstract
Provided is a battery module assembly in which unit modules are stacked. Each of the unit modules includes: a plurality of battery cells; and a plurality of cartridge assemblies for respectively fixing the plurality of battery cells. The battery module assembly includes: a sensing assembly mounted to upper ends of the plurality of cartridge assemblies and assembled thereto; a front cover for covering front surfaces of the cartridge assemblies; and a connector coupled and fixed to the front cover. The connector includes: a connector body; and a first protrusion region that protrudes from the connector body. An upper sensing assembly connection hole is formed in an upper region of each of the cartridge assemblies.
Claims16
A battery module assembly in which unit modules are stacked, comprising:
