Embodiment Construction

[0049] now refer to figure 1 and 2 , the battery module of the present embodiment includes a box-shaped case 10 with at least one side open, a plurality of partition walls 16 integrally formed in the case 10 at certain intervals, and a plurality of partition walls 16 separated from each other by the partition walls 16 and inserted thereinto. A unit cell 20 in the casing 10 .

[0050] As described above, since the plurality of partition walls 16 are installed in the case 10 at intervals, spaces 11 are formed between the partition walls 16 to insert the unit cells 20 therein.

[0051] The housing 10 has a pair of support plates 12 formed to face each other at both ends of the housing and a pair of side plates 14 connected to the support plates 12 at both ends thereof and to two sides of each partition wall 16. The edges are fixed together. The support plate 12 of the housing 10 is installed parallel to the partition wall 16 , while the side plate 14 is installed vertically to...

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.

Description

[0001] This application is a divisional application of the invention patent application with the application number 200510129182.3, the application date is October 28, 2005, the applicant is Samsung SDI Co., Ltd., and the invention name is "battery module". technical field [0002] The present invention relates to a battery module, in particular to a battery module capable of accommodating a partition wall at a fixed installation position and improving the bonding force of unit cells in a housing. Background technique [0003] In general, secondary batteries are rechargeable and can be used repeatedly. In particular, secondary batteries including only one battery cell are mainly used in various small portable electronic devices, such as for cellular phones, laptop computers, cameras, and camcorders. A high-capacity secondary battery (hereinafter referred to as a 'battery module') is composed of a plurality of single cells {hereinafter referred to as 'unit batteries' (unit ba...
