Abstract: A battery interconnect may include a desired current capacity, integrated fusible links, and be manufacturable using cost effective techniques. In some embodiments, a battery interconnect includes a busbar and relatively thinner links. A busbar carries larger currents and accordingly its cross-sectional areas are relatively larger to reduce ohmic losses. A link carries a much smaller current, and a fusible link is configured to break the circuit when the current is above a threshold, thus requiring a relatively small cross-sectional area. These sometime disparate length scales are addressed using several techniques such as layering a busbar and a foil sheet and pressing portions of a busbar to form the links. The links can be affixed to a plurality of battery cells to connect the cells in parallel or series.

Abstract: Systems and methods that provide improved cooling for batteries are disclosed. A battery system according to the present disclosure may include a cooling plate, one or more battery cells coupled to one surface of the cooling plate, and one or more battery cells coupled to the opposite surface of the cooling plate. The cooling plate and corresponding batteries may be included in a battery module, and multiple battery modules electrically connected may make up a battery pack. The cooling plates may comprise channels for cooling fluid, which may be provided to the plates in parallel from a cooling fluid source. Cooling the battery cells at the ends of the cells, where they are coupled to the cooling plate, may advantageously provide one or more of improved energy density, thermal management, and safety.

Abstract: Systems and methods are described herein for analyzing the application of adhesives. An adhesive comprising a fluorescent property is applied to a component. The component is illuminated using one or more of wavelengths of light from a light source, wherein the adhesive is configured to absorb the one or more wavelengths of light and fluoresce in response. An image of the component is captured using a camera while the component is illuminated using the light source. One or more fluorescence characteristics from the image are determined and a state of the applied adhesive is determined based on the one or more fluorescence characteristics.

Abstract: A battery system includes one or more shear walls to provide support. A shear wall may include a support structure and conductive traces to route signals or measurements without the need for wire runs. The support structure may help to maintain the arrangement of battery cells of the battery system, while the conductive traces allow voltages among the battery cells to be monitored. Busbars, or other electrical terminals, may be coupled to the conductive traces of the shear wall, and processing equipment may also be coupled to the conductive traces. Accordingly, the processing equipment may monitor voltage among the battery cells, which may allow balancing among battery modules, diagnostics, and other functions. The shear wall may be constructed of FR-4 or other circuit board material, and the conductive traces may include bonded copper, or other electronically conductive material.
