Abstract

A battery pack having a battery housing that defines a cavity for receiving a plurality of battery cells. The battery pack cavity is sealed from the air outside the battery pack housing to prevent water and other contaminants from reaching the plurality of battery cells.

First claim

1 . A battery pack comprising:
a housing comprising a lower housing and upper housing assembled together at a parting line to form an internal cavity; the lower housing and the upper housing each including a mating surface, wherein the mating surface of the lower housing mates with the mating surface of the upper housing at the parting line; a groove formed in one of the lower housing mating surface and the upper housing mating surface and a tongue formed in the other of the lower housing mating surface and the upper housing mating surface; a sealing material positioned in the groove to provide a seal between the lower housing and the upper housing when the lower housing and the upper housing are assembled; a terminal block; a sealing material surrounding the terminal block; and a wall extending from an interior surface of the upper housing wherein the wall mates with the sealing material surrounding the terminal block.

2 . The battery pack, as recited in claim 1 , wherein the sealing material is an O-ring.

3 . The battery pack, as recited in claim 1 , wherein the sealing material is molded in place in the groove.

4 . The battery pack, as recited in claim 1 , wherein the sealing material surrounding the terminal block is an O-ring.

5 . The battery pack, as recited in claim 1 , wherein the sealing material surrounding the terminal block is a potting material.

6 . The battery pack, as recited in claim 5 , wherein the potting material is a low pressure mold material.

7 . The battery pack, as recited in claim 1 , further comprising a latch receiving cavity formed in the upper housing and a latch for affixing the housing to an external device, the latch received in the latch receiving cavity, the latch receiving cavity sealed from the internal cavity.

8 . A battery pack comprising:
a housing comprising a lower housing and upper housing assembled together at a parting line to form an internal cavity; a plurality of battery cells positioned in the internal cavity; a latch receiving cavity formed in the upper housing and a latch for affixing the housing to an external device, the latch received in the latch receiving cavity, the latch receiving cavity sealed from the internal cavity.

9 . The battery pack, as recited in claim 8 , wherein the upper housing includes a first wall, a second wall, a third wall and a fourth wall, the first, second, third, and fourth walls meet to form the latch receiving cavity.

10 . The battery pack, as recited in claim 9 , wherein the first, second, third, and fourth walls are formed integrally with each other during formation of the upper housing.
