  • Publication number: 20250135857
    Abstract: An electric work vehicle includes a frame, a front axle connected to the frame, a first motor supported by the frame and connected to a first gearing to drive a first wheel, and a second motor supported by the frame and connected to a second gearing to drive a second wheel. An outermost portion of the first gearing in a left-right direction of the electric work vehicle is outside of the frame in the left-right direction of the electric work vehicle. An outermost portion of the second gearing in the left-right direction of the electric work vehicle is outside of the frame in the left-right direction of the electric work vehicle.

  • Publication number: 20250135876
    Abstract: An electric work vehicle includes a frame, a first motor to drive a first wheel, the first motor being supported by the frame and mounted on a first motor baseplate, and a second motor to drive a second wheel, the second motor being supported by the frame and mounted on a second motor baseplate. The first motor baseplate and the second motor baseplate are spaced apart from each other to define a space between the first motor baseplate and the second motor baseplate. A portion of a first motor power connection line and a portion of a second motor power connection line are located in the space between the first motor baseplate and the second motor baseplate. A first power receiving terminal of the first motor which is connected to the first motor power connection line is located at a rear portion of the first motor.

  • Publication number: 20250118831
    Abstract: Described herein are swappable battery modules comprising immersion-thermally controlled prismatic battery cells and methods of operating thereof. A method comprises positioning a swappable battery module on a battery dock comprising dock fluidic ports and sliding the swappable battery module to the dock fluidic ports until these dock's ports are fluidically coupled with the module's fluidic ports. Specifically, the dock comprises an enclosure and a module support rail slidably coupling the swappable battery module and the enclosure. The module support rail comprises a rail base, a first slider, a second slider, and a lever-based unit, interconnecting the rail base and both sliders. The rail base is fixed to the enclosure, while the second slider is detachably coupled to the module. The two sliders move at different speeds or at the same speed relative to the dock base depending on the proximity of the first end plate to the dock base.

  • Publication number: 20240421379
    Abstract: Described herein are swappable battery modules comprising immersion-thermally controlled prismatic battery cells and methods of operating thereof. A method comprises positioning a swappable battery module on an external charger comprising charger fluidic ports and sliding the swappable battery module to the charger fluidic ports until these charger's ports are fluidically coupled with the module's fluidic ports. Specifically, the external charger comprises an enclosure and a module support rail slidably coupling the swappable battery module and the enclosure. The module support rail comprises a rail base, a first slider, a second slider, and a lever-based unit, interconnecting the rail base and both sliders. The rail base is fixed to the enclosure, while the second slider is detachably coupled to the module. The two sliders move at different speeds or at the same speed relative to the charger base depending on proximity of the first end plate to the charger base.
