Abstract

Techniques are disclosed for systems and methods to provide modular battery assemblies for micro-mobility fleet vehicles. A modular battery assembly for a micro-mobility fleet vehicle includes a battery assembly enclosure including an assembly retention interface configured to physically secure the assembly enclosure to a subframe assembly of the micro-mobility fleet vehicle, a battery cell assembly disposed within the battery assembly enclosure, and an enclosure lid mounted to the assembly enclosure. The modular battery assembly may include an arched floorboard panel configured to provide a floor board surface for the micro-mobility fleet vehicle. The battery cell assembly may include a honeycomb battery cell holder and a collector board atop the battery cell holder to provide wire bond interconnects between the battery cells.

Claims20

Dependent claims

A modular battery assembly for a micro-mobility fleet vehicle, the modular battery assembly comprising:

a rectangular cuboid shaped battery assembly enclosure comprising an enclosure cavity, an interface mounting orifice disposed within a wall of the battery assembly enclosure, a battery assembly electrical interface mounted at least partially within the interface mounting orifice, a head assembly retention interface disposed along a front portion of the battery assembly enclosure, and a tail assembly retention interface disposed along arear portion of the battery assembly enclosure, wherein the head and tail assembly retention interfaces are configured to physically secure the battery assembly enclosure to a subframe assembly mountable to the micro-mobility fleet vehicle;
a battery cell assembly disposed within the enclosure cavity and electrically coupled to the battery assembly electrical interface of the battery assembly enclosure;
an enclosure lid mounted to the battery assembly enclosure and configured to seal the enclosure cavity;
and
an arched floorboard panel with a handle, the arched floorboard panel mounted to the enclosure lid and configured to provide a floorboard surface defined by a laterally extending tensioned arch, wherein the arched floorboard panel and the battery assembly enclosure are configured to distribute a step weight of a rider of the micro-mobility fleet vehicle along the subframe assembly.
