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: A battery monitoring module may be arranged in such a way as to receive a sensor signal from a light sensor configured to detect light within a battery module. The battery monitoring module may determine, using processing circuitry, a light characteristic within the battery module based on the sensor signal. The battery monitoring module may determine, using processing circuitry, a battery condition of the battery module based on the light characteristic.

Abstract: A separating member for separating a plurality of battery cells is provided, which includes a plurality of first walls and a plurality of second walls having a thickness larger than a thickness of the first walls. The separating member is expandable from a collapsed state to an expanded state. The separating member has a plate configuration in the collapsed state and has a honeycomb structure in the expanded state. The plurality of first walls and the plurality of second walls jointly define a plurality of cell units of the honeycomb structure.
