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.

First claim

What is claimed is:

1. 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.

2. The modular battery assembly of claim 1 , wherein:
the head assembly retention interface comprises a slip pin configured to engage with a slip pin tab of the subframe assembly; and
the tail assembly retention interface comprises a lock pin configured to engage with a lock pin tab of the subframe assembly.

3. The modular battery assembly of claim 2 , wherein:
the arched floorboard panel comprises one or more arch support guides configured to receive the slip pin tab and/or the lock pin tab and provide compression to the arched floorboard panel; and
the handle is integrated with the arched floorboard panel.

4. The modular battery assembly of claim 1 , wherein:
the head assembly retention interface comprises a hinge receiver recess configured to engage with a hinged assembly retention mechanism of the subframe assembly; and
the tail assembly retention interface comprises a pawl configured to engage with a locking surface of a locking cam of the subframe assembly.

5. A system comprising the modular battery assembly of claim 4 and the subframe assembly, wherein:
the hinge receiver recess is integrated with the battery assembly electrical interface of the battery assembly enclosure;
the hinged assembly retention mechanism of the subframe assembly comprises a subframe assembly electrical interface for connection with the battery assembly electrical interface; and
the locking cam of the subframe assembly is coupled to a worm gear actuated by an electromechanical actuator of the subframe assembly to release the modular battery assembly from the subframe assembly.

6. The modular battery assembly of claim 1 , wherein:
the head assembly retention interface comprises a recessed latch receptacle configured to engage with a push latch assembly retention mechanism of the subframe assembly; and
the tail assembly retention interface comprises a slide lever feature configured to engage and form a fulcrum with a slide lever assembly retention mechanism of the subframe assembly.

7. A system comprising the modular battery assembly of claim 6 and the subframe assembly, wherein:
the recessed latch receptacle is integrated with the battery assembly electrical interface of the battery assembly enclosure; and
the push latch assembly retention mechanism comprises a worm gear actuated by an electromechanical actuator of the subframe assembly to release the modular battery assembly from the subframe assembly.

8. A micro-mobility fleet vehicle comprising:
a subframe assembly; and
a 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, and an assembly retention interface disposed along the battery assembly enclosure, wherein the assembly retention interface is configured to physically secure the battery assembly enclosure to the subframe assembly;
a battery cell assembly disposed within the enclosure cavity and electrically coupled to the battery assembly electrical interface;
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.

9. The micro-mobility fleet vehicle of claim 8 , wherein:
the modular battery assembly is physically secured to the subframe assembly by the assembly retention interface; and
the assembly retention interface comprises a slip pin configured to engage with a slip pin tab of the subframe assembly or a lock pin configured to engage with a lock pin tab of the subframe assembly.

10. The micro-mobility fleet vehicle of claim 9 , 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 mounted to the micro-mobility fleet vehicle; and
the arched floorboard panel comprises one or more arch support guides configured to receive the slip pin tab and/or the lock pin tab and provide lateral compression of the arched floorboard panel.

11. The micro-mobility fleet vehicle of claim 8 , wherein:
the assembly retention interface comprises a hinge receiver recess configured to engage with a hinged assembly retention mechanism of the subframe assembly; and
the hinged assembly retention mechanism of the subframe assembly comprises a hinge guide configured to pivot about a lateral axis of the micro-mobility fleet vehicle.

12. The micro-mobility fleet vehicle of claim 11 , wherein:
the hinge receiver recess is integrated with the battery assembly electrical interface of the battery assembly enclosure;
the hinged assembly retention mechanism of the subframe assembly comprises a subframe assembly electrical interface integrated with the hinge guide;
the locking cam of the subframe assembly is coupled to a worm gear actuated by an electromechanical actuator of the subframe assembly that is configured to release the modular battery assembly from the subframe assembly; and
the subframe assembly comprises a wiring channel configured to route a power bus from the modular battery assembly to a motor controller of the micro-mobility fleet vehicle.

13. The micro-mobility fleet vehicle of claim 8 , wherein:
the assembly retention interface comprises a recessed latch receptacle configured to engage with a push latch assembly retention mechanism of the subframe assembly; and
the recessed latch receptacle is integrated with the battery assembly electrical interface of the battery assembly enclosure.

14. The micro-mobility fleet vehicle of claim 8 , wherein:
