Abstract

A battery module includes a plurality of battery cell assemblies, each battery cell assembly including at least one battery cell, and a module frame extending in a longitudinal direction of the plurality of battery cell assemblies, the module frame accommodating therein the plurality of battery cell assemblies in a row in the longitudinal direction.

First claim

1 . A battery module comprising:
a plurality of battery cell assemblies, each battery cell assembly including at least one battery cell; and a module frame extending in a longitudinal direction of the plurality of battery cell assemblies, the module frame being configured to accommodate therein the plurality of battery cell assemblies in a row in the longitudinal direction.

2 . The battery module according to claim 1 , wherein the plurality of battery cell assemblies comprise:
a first battery cell assembly comprising the at least one battery cell; and a second battery cell assembly comprising the at least one battery cell, wherein the first battery cell assembly and the second battery cell assembly are slidably inserted into and mounted on the module frame.

3 . The battery module according to claim 2 , wherein the first battery cell assembly is slidably inserted into a first side of the module frame, and
wherein the second battery cell assembly is slidably inserted into a second side of the module frame opposite the first side.

4 . The battery module according to claim 2 , further comprising:
a front cover covering a first side of the module frame; and a rear cover opposite to the front cover, the rear cover covering the a second side of the module frame.

5 . The battery module according to claim 4 , wherein the front cover comprises:
a front end plate having a size corresponding to the first side of the module frame; a front sealing plate located between the front end plate and the first battery cell assembly; and a front sealant applied to an edge of the front sealing plate.

6 . The battery module according to claim 4 , wherein the rear cover comprises:
a rear end plate having a size corresponding to the second side of the module frame; a rear sealing plate located between the rear end plate and the second battery cell assembly; and a rear sealant applied to an edge of the rear sealing plate.

7 . The battery module according to claim 1 , wherein the module frame comprises at least one cooling passage for cooling the plurality of battery cell assemblies.

8 . The battery module according to claim 7 , wherein the at least one cooling passage extends in the longitudinal direction of the module frame, and the at least one cooling passage is provided inside a lower portion of the module frame.

9 . A battery pack comprising a plurality of battery modules according to claim 1 ,
wherein the plurality of battery modules are arranged in parallel in a width direction of the module frame, and adjacent battery modules of the plurality of battery modules are connected by bolts extending between the corresponding module frames facing each other in the width direction.

10 . A vehicle comprising at least one battery pack according to claim 9 .

11 . The battery module of claim 5 , wherein the front cover further comprises a front cooling manifold.

12 . The battery module according to claim 11 , wherein the module frame further comprises at least one cooling passage for cooling the plurality of battery cell assemblies, the at least one cooling passage being connected to the front cooling manifold.

13 . The battery module of claim 6 , wherein the rear cover further comprises a rear cooling manifold.

14 . The battery module according to claim 13 , wherein the module frame further comprises at least one cooling passage for cooling the plurality of battery cell assemblies, the at least one cooling passage being connected to the rear cooling manifold.
