Non-welded battery module

Abstract

This invention relates to an improvement in battery packs. The present invention resides in a combination of an electric battery pack and a apparatus for making an electrical connection to the battery without involving the spot welding process. The present assembly method enables terminal blocks containing multiple battery packs joint in series having a “U-turn” configuration without external electrical connection. Any two battery packs are firmly locked together through the pressure plates (200) without being electrically connected together. The present embodiment uses two separate nickel or other conductive material plated copper sheets (113a or 113b) that are embedded between the battery cell holder (114a, 114b) and the silicone rubber pressure sheet (112a, 112b). The first end portion block of battery packs supported by an end pressure plate (300) can be connected together to the second end portion of the block battery packs by using a modified nickel or other conductive material plated copper sheet (113) that enable the two battery packs to be connected internally, thus, making the “U-turn” configuration possible. This method is one of the most cost efficient ways to connect internally, to avoid using any external wires or circuits, which eventually maintain the internal resistance of each of the battery packs.
