    Abstract: A battery cell pack has a plurality of battery cells that are assembled into a prismatic frame, with deformable separators interposed to accommodate elastic and plastic deformation caused by cyclic and acyclic expansion and contraction thereof during charging and discharging over the life of the battery cell pack. The battery cells are arranged in a horizontal stack within the prismatic frame, and the deformable separators are interposed between subsets of the battery cells. The deformable separators exert compressive force on the subsets of the battery cells along a longitudinal axis that is defined by the horizontal stack. The compressive force exerted by the deformable separators is at least a minimum force over a service life of the battery cell pack.

  • Publication number: 20230294670
    Abstract: Presented are adaptive operator assistance systems for motor-assisted manually powered (MMP) vehicles, methods for making/using such systems, and electric scooters equipped with such systems. A method of operating an MMP vehicle using a handheld mobile computing device (MCD) includes the handheld MCD receiving path plan data for the MMP vehicle and then receiving, based on this path plan data, MMP-specific ambient data that is aligned with the vehicle's present location and contains surrounding environment data particular to the MMP vehicle. A wireless location device of the handheld MCD tracks the MMP vehicle's real-time location, and a sensing device of the handheld MCD detects MMP-specific threat data that is aligned with the vehicle's real-time location and contains user danger data particular to the MMP vehicle. The handheld MCD then commands a resident subsystem of the MMP vehicle to execute a control operation based on the MMP-specific ambient data and/or threat data.
