Abstract

Disclosed are a battery module and a battery pack including the same. The battery module includes a frame; and a plurality of battery cells disposed at the frame, and the plurality of battery cells are arranged in a single layer with respect to the frame.

Claims

1. A battery module, comprising:

a frame;

a plurality of battery cells disposed at the frame; and

a control unit disposed at a center portion of the frame and electrically connected to the plurality of battery cells only via the frame,

wherein the plurality of battery cells are arranged in a single layer with respect to the frame, and

wherein the frame further includes a space partition guide formed at the frame to distinguish a space in which the plurality of battery cells are disposed, an upwardly protruding portion of the space partition guide being disposed directly between respective electrode leads of two adjacent battery cells among the plurality of battery cells.

2. The battery module according to claim 1, wherein the plurality of battery cells are arranged in at least one row or in at least one column.

3. The battery module according to claim 1, wherein the frame includes:

an outer frame member forming an appearance thereof; and

an inner frame member disposed in an empty space of the outer frame member with a predetermined interval.

4. The battery module according to claim 3, wherein the frame is made of a conductive material.

5. The battery module according to claim 4, wherein the battery cells are respectively electrically coupled to the outer frame member and the inner frame member or respectively electrically coupled to a plurality of inner frame members.

6. The battery module according to claim 1, wherein a seating groove is formed at the frame so that electrode leads of the battery cells are coupled thereto.

7. A battery pack, comprising the battery module defined in claim 1.

8. A vehicle, comprising the battery module defined in claim 1.
