Disclosed is a battery pack, which includes a battery module having a plurality of battery cells, a case configured to accommodate a plurality of the battery modules, and a protection cover coupled to the case to be capable of opening or closing, the protection cover being configured to protect an installation member installed at the case, wherein the protection cover is pivotally coupled to the case and is separable from the case depending on a pivoting angle of the protection cover.
1. A battery pack, comprising:
a case configured to accommodate a plurality of battery modules, each of the plurality of battery modules including a plurality of battery cells;
at least one of the plurality of battery modules; and
a protection cover coupled to the case and configured to be capable of opening or closing, the protection cover being further configured to protect an installation member installed in the case,
wherein the protection cover is pivotally coupled to the case,
wherein the protection cover is separable from the case, depending on a pivoting angle of the protection cover, and
wherein the at least one of the plurality of battery modules is in the case.
2. The battery pack according to claim 1 , wherein:
a coupling groove is in the case;
a coupling protrusion pivotally coupled to the coupling groove is in the protection cover; and
the protection cover is pivotally coupled to the case by coupling the coupling protrusion and the coupling groove, so that the protection cover is separated from the case within a preset angle range, and
the protection cover is prevented from being separated due to interference of the protection cover and the case at an angle beyond the preset angle range.
3. The battery pack according to claim 2 , wherein a first protruding portion is in the protection cover and is configured to protrude from the protection cover at a location near the coupling protrusion to come into contact with the case, and thus interfere with the case when the protection cover is separated at an angle beyond the preset angle range.
4. The battery pack according to claim 3 , wherein a second protruding portion protrudes from the case and is configured to come into contact with the first protruding portion.
5. The battery pack according to claim 3 , further comprising an insert groove near the coupling groove, the insert groove being configured so that the first protruding portion is inserted therein when the protection cover is pivoted to prevent the protection cover from being pivoted beyond a preset range.
6. The battery pack according to claim 2 , wherein:
the protection cover includes:
a first cover member including the coupling protrusion; and
a second cover member bent and extending from the first cover member; and
the second cover member is configured to come into contact with the case, and thus interfere with the case when the protection cover is separated at an angle beyond the preset angle range.
7. The battery pack according to claim 1 , wherein the protection cover is coupled to the case by a latch member.
8. A vehicle, comprising the battery pack of claim 1 .
