Patent ID: 8652678

Claim:
A battery pack system for providing electric power during use, wherein the battery pack system comprises: at least two cell carrier assemblies configured to provide electric current during use, each of the at least two cell carrier assemblies having a substantially planar configuration, each cell carrier assembly having a cell configured to provide the electrical current, the cell having positive and negative tabs to provide positive and negative electrical connections; a battery pack enclosure for housing the at least one cell carrier assembly, the battery pack enclosure having at least one wall with at least one channel sized to receive an edge of the cell carrier assembly to maintain the at least one cell carrier assembly at a location within the battery pack enclosure and provide a thermal pathway during use; and at least two connectors to releasably engage tabs from different cells, each of the at least two connectors comprising: a body with angled sidewalls defining a channel therebetween, at least one engagement member disposed within the channel, the at least one engagement member having at least one angled edge that is complimentary to one of the angled sidewalls of the body, and coupling elements to releasably secure the tabs from the different cells between the at least one engagement member and the sidewalls of a given connector to provide an electrical connection between the different cells and a thermal heat sink for the tabs in use.
