Battery grid packaging that organizes internal wires and exposes a current collection lug for easier, cheaper battery assembly.
This design uses a rigid frame with internal wiring to create defined open areas while routing a current collection lug out through the top. It’s technically significant because it standardizes current collection geometry inside the grid, reducing assembly variability across cells and strings. Previously, using this specific wire-and-lug grid layout required licensing from the patent holder for products that implemented the same structure.
Design and sell modular EV and stationary battery packs using this grid frame to speed assembly and cut integration costs.
A battery grid includes a frame that includes a top element, a bottom element, a first side element, and a second side element. The battery grid also includes a plurality of wires provided within the frame and defining a plurality of open areas and a current collection lug extending from the top element in a first direction.
