Battery module

摘要

A battery module includes a plurality of unit batteries, each unit battery having a terminal having a terminal contact portion. An electrically conductive adaptor connects the terminals of adjacent unit batteries, the electrically conductive adaptor having an adaptor contact surface. The terminal contact portion has a contact portion contact surface coupled to the adaptor contact surface. The contact portion contact surface and the adaptor contact surface are parallel to a longitudinal axis of the terminal. The electrically conductive adaptor may have a U-shaped cross-section, and the terminal may comprise a slit parallel to the longitudinal axis of the terminal.
