Description

1. Field

Embodiments relate to a battery pack.

2. Description of the Related Art

Recently, a high-power battery pack using a nonaqueous electrolyte having a high energy density has been developed. The high-power battery pack may form a large-capacity battery pack by connecting a plurality of secondary batteries to be used for, e.g., motor drive of machines requiring a high power source such as hybrid electric vehicles.

The plurality of secondary batteries may be accommodated in a case to then constitute a battery pack. The case may have a connector that electrically connects the secondary batteries to an external device.

Embodiments are directed to a battery pack, which represents advances over the related art.

At least one of the above and other features and advantages may be realized by providing a battery pack including a plurality of battery cells; a housing accommodating the plurality of battery cells; a connector coupled to the housing, at least a portion of the connector being exposed outside of the housing; and a sealing member coupled to the connector, the sealing member surrounding the exposed portion of the connector.

The sealing member may include rubber.

The sealing member may include a thread hole therein.

The connector may include a thread groove therein, the thread groove corresponding to the thread hole.

The housing may include a case in which the battery cells are placed; a top cover covering an upper portion of the case; and a side cover covering a side surface of the case.
