Abstract
A battery pack, including a bare cell, a protection circuit board electrically connected to the bare cell, the protection circuit board including a checking unit to check whether the protection circuit board is operational, an upper case disposed on an upper side of the bare cell, the upper case having a checking hole defined therein to check the protection circuit board, the checking hole being formed to be opened to the checking unit, and a water penetration sensor, combined with an exterior of the checking hole, to cover the checking hole.
Claims12
A battery pack, comprising:
- a bare cell;
- a protection circuit board electrically connected to the bare cell, the protection circuit board including a checking unit to check whether the protection circuit board is operational;
- an upper case disposed on an upper side of the bare cell, the upper case having a checking hole defined therein to allow for a checking of the protection circuit board, the checking hole being formed to expose the checking unit;
- and
- a water penetration sensor to externally cover the checking hole.
A method of manufacturing a battery pack, comprising:
- connecting a bare cell to a protection circuit board including a checking unit capable of displaying whether the bare cell is operational;
- combining an upper side of the bare cell with an upper case, on which a checking hole is formed to be opened to the outside of the upper case, so as to allow for an examination of the checking unit;
- examining the checking unit through the checking hole to determine whether the protection circuit board is operational;
- and
- covering, externally, the checking hole with a water penetration unit.
A battery pack to encase a bare cell, comprising:
- an upper case, disposed on an upper side of the bare cell, having at least one checking hole defined therein;
- and
- a protection circuit board electrically connected to the bare cell to check at least one of an over-charge blocking voltage, an over-charge recovery voltage, an over-discharge blocking voltage, an over-discharge recovery voltage, and/or an over-current blocking current of the bare cell through the at least one checking hole;
- and
- a water penetration sensor to externally cover the checking hole.
