Abstract
A method and apparatus for simplifying battery pack encapsulation is provided. The battery pack includes a pair of complementary housing members with each housing member including a plurality of cell constraints into which the ends of corresponding battery cells are inserted during assembly. One or both housing members also include at least one, and preferably a plurality, of raised encapsulant injection ports. The raised encapsulant injection ports are designed to extend above the surface of the respective housing members and beyond the injected encapsulation material, thus ensuring that the ports remain open after encapsulation material injection.
