BATTERY MODULE COMPRISING BATTERY CELLS OR UNIT MODULES HAVING MULTI- DIRECTIONAL CONNECTION STRUCTURE

摘要

The present invention provides a battery module, as the battery module comprising two or more battery cells or unit modules, in which two or more positive electrode or negative electrode terminals are individually formed at one end unit in the battery cells or the unit modules. The battery cells and the unit modules are connected in series or in parallel in a state in which electrode terminals are stacked or arranged in a side surface to head towards the same direction.
