Method of preparing battery core pack
First Claim
1. A method of manufacturing a battery core pack having two or more unit cells connected in parallel with each other and two or more unit cells connected in series with each other, wherein the battery core pack is manufactured through the combination ofa first connecting member having a connection part extending from the outer surface of a plate body of the first connecting member;
- a second connecting member having a connection part extending from the left or right outer surface of a plate body of the second connecting member, and a bending guide groove formed at the upper edge and/or the lower edge of the middle of the plate body of the second connecting member; and
a third connecting member having a connection part extending from the outer surface of a plate body of the third connecting member adjacent to the middle of the plate body of the third connecting member, and a bending guide groove formed at the upper edge and/or the lower edge of the middle of the plate body of the third connecting member, wherebythe first connecting member is used when the unit cells are connected only in the lateral direction according to the construction of the battery core pack, andthe second connecting member and/or the third connecting member are used when the unit cells are connected in the lateral direction and, at the same time, in the longitudinal direction according to the construction of the battery core pack.

Abstract
Disclosed herein is a method of manufacturing a battery core pack having a plurality of unit cells, especially a plurality of cylindrical batteries, which are connected with each other by connecting members. According to the present invention, the structure of the battery core pack can be easily modified by merely changing the combination of the connecting members without manufacturing additional connecting members. Consequently, common use of the connecting members is possible.
