1. A battery module comprising:
- a case comprising a pair of opposing side plates and a pair of opposing supporting plates and having an opening on a side substantially perpendicular to the side plates and the supporting plates;
a plurality of partition walls spaced apart at intervals in the case;
a plurality of unit batteries insertable into the case through the opening in an insertion direction, adjacent unit batteries being separated from each other by a partition wall of the plurality of partition walls; and
a battery fixing structure between the case and respective unit batteries of the plurality of unit batteries, the battery fixing structure comprising a fixing projection protruding from a side face of the respective unit battery and a cutout formed through one of the opposing side plates of the case and forming a projection receiving portion,wherein the side face of the respective unit battery and the one of the opposing side plates of the case face a direction substantially perpendicular to the insertion direction, andwherein the fixing projection is insertable into the projection receiving portion for reducing positional movement of the respective unit battery in at least the insertion direction.

Abstract
A battery module includes a case with at least one face which is opened, a plurality of partition walls fixedly installed at predetermined intervals in the case, and a plurality of unit batteries which are separated from each other with the partition walls therebetween to be inserted into the case. The battery module may include a battery fixing structure which is installed between the case and the unit batteries to fix the unit batteries so as to prevent positional movement of the unit batteries in the case. The battery fixing structure may be a concavo-convex engaging structure including fixing projections and projection receiving portions.
