Abstract

The invention discloses a battery module assembly and a method for assembling the battery. The battery module assembly includes a plurality of modules into which a plurality of battery cells are preassembled. The modules are compressed by end plates held together in compression by a plurality of connecting parts. The end plate may include a protruding portion that applies pressure to a central portion of the battery cell within the module. The central portion of the end plate may be part spherical, part cylindrical or a flat surface.

Description

technical field [0001] The invention relates to a method of manufacturing a battery for a vehicle having an electric traction motor and to components of a battery assembly. Background technique [0002] High voltage (HV) battery systems for vehicles are manufactured by assembling battery cells, electrical connections and cooling equipment to provide a tight package with minimal open space. Cassette cells can be used in high volume, production HV battery systems. A cartridge cell is typically a generally planar layered ion battery, such as a lithium-ion battery, that may be sandwiched between structural and / or thermal regulating layers. A large number of unit cells are stacked in one or more rows and held in a compact array. [0003] The bracket or bracket holding the battery array should be robust to securely hold the battery cells in the vehicle. In addition, battery cells may be assembled into subassemblies off an assembly line before being installed in a vehicle. Hand...
