Abstract: Typically, the battery swapping process of a battery-powered mobile equipment involves driving or otherwise moving and transporting the battery pack of the mobile equipment at the recharging station, and support mobile equipment may not be properly equipped to perform an efficient and safe battery swap. The availability of mobile equipment designed to replace battery packs on-site are limited and may not be suitable for most battery pack assemblies. Disclosed embodiments eliminate or reduce the risk during the battery swapping and transport of battery packs to recharging stations. In particular, disclosed embodiments comprise a battery-swapping support system that enables battery packs to be quickly swapped, potentially in the field. The battery-swapping support system may be mounted on a mobile equipment that can transport battery packs to and from other mobile equipment in the field.

Abstract: Typically, the recharging process for a battery-powered mobile equipment involves driving or otherwise moving the mobile equipment to the location of a stationary recharging station, and recharging the battery of the mobile equipment at the recharging station. During the time of travel and recharging, the mobile equipment is not performing a task in the field. Disclosed embodiments eliminate or reduce the need to transport the mobile equipment to recharging stations. In particular, disclosed embodiments comprise a frame that enables battery packs to be quickly swapped, potentially in the field. Embodiments may comprise movement elements to facilitate swapping and/or a mobile battery-swapping system that can transport battery packs to and from the mobile equipment in the field.

Abstract: Some implementations described herein relate to a work tool coupler for a work machine. The work tool coupler may include a mechanical interface configured to mechanically couple a work tool to the work machine. The work tool coupler may include an electrical interface between the work tool and the work machine. The electrical interface may include one or more electromagnets configured to guide or fix the work tool in a coupled position with respect to the work tool coupler. The electrical interface may include a transmitter coil configured to wirelessly provide electrical energy from a power source included in the work machine to the work tool.

Abstract: A disconnect clutch and method of controlling the connection of a parasitic load to an engine disposed on a machine is disclosed. The disconnect clutch may comprise a flywheel assembly, a friction plate and a coupling. The flywheel assembly may include a flywheel having a cavity, a chamber, a piston moveable between a contracted position and an expanded position, a pressure plate, a lever, and a coupling operably connected to the friction plate. The flywheel may include an end plate. The chamber may be defined by the flywheel and the piston. The lever may apply an activation force to the pressure plate when the piston is in the expanded position. The friction plate may be attached to and rotatable with the flywheel assembly when the piston is in the expanded position and generally stationary when the piston is in the contracted position.

Abstract: A control system for controlling speed of an engine of a work machine having a hydrostatic transmission is disclosed. The control system may include a power source and a hydrostatic transmission operatively coupled to the power source. The control system may also include a controller capable of receiving information from the power source and the transmission and actively controlling an engine speed of the work machine to reduce the engine speed below a threshold value to emulate an engine lug during a stall condition.

Abstract: A machine includes a plurality of torque consuming devices drivingly coupled with an internal combustion engine. The plurality of torque consuming devices includes a continuously variable transmission coupling the internal combustion engine with a plurality of ground engaging elements. An electronic controller is in communication with the internal combustion engine and the plurality of torque consuming devices and is configured to execute a torque load control algorithm for generating a torque load limit based, at least in part, on an engine underspeed value. The electronic controller identifies a potential engine stall event during which a current engine speed of the internal combustion engine drops below the engine underspeed value by a predetermined amount, and executes a transient torque load control algorithm to adjust the torque load limit responsive to the identification of the potential engine stall event.
