Battery cartridge for novel structure and open type battery module containing the same
First Claim
1. A battery cartridge comprising:
- first and second outer frame members (a, b) for receiving first and second unit cells; and
an inner frame member (c) disposed between the outer frame members (a, b), wherein the first unit cell is mounted between the first outer frame member (a) and the inner frame member (c),the second unit cell is mounted between the second outer frame member (b) and the inner frame member (c),the inner frame member (c) has a plurality of through-holes, which directly communicate with external air outside of the battery cartridge while the first and second unit cells are mounted between the outer and inner frame members,wherein the first and second unit cells are pouch-shaped cells formed in a shape of a rectangle, andthe first unit cell is disposed on the first outer frame member (a) while an edge part of the first unit cell is disposed on an inside part of the first and second outer frame member (a), andthe inner frame member (c) has a left frame part and a right frame part, andthe plurality of through-holes are formed through the left frame part and the right frame part of the inner frame member (c) at a direction horizontal to the inner frame member (c), andthe first and second outer frame members (a, b) and/or the inner frame member (c) have depressions corresponding to a thickness of electrode leads of the first and second unit cells such that at least a portion of the electrode leads of the first and second unit cells extend through the depressions and are disposed external of the first and second outer frame members (a, b) and/or the inner frame member (c) when the inner frame member (c) is coupled to the first and second outer frame members (a, b).

Abstract
A battery cartridge includes a pair of outer frame members for receiving unit cells and an inner frame member disposed between the outer frame members. The unit cells are mounted between the outer and inner frame members. The inner frame member has a plurality of through-holes, which communicate with the outside while the unit cells are mounted between the outer and inner frame members. An opened type battery module includes such a battery cartridge. The battery cartridge and the battery module have a high structural integration and mechanical strength. Consequently, the present invention has the effect of minimizing the size of a battery system, stably mounting unit cells having low mechanical strength, and effectively removing heat from the unit cells.
