Abstract: A system for charging a battery unit to power a work machine. The system includes a charger to charge the battery unit, charging receptacles, power supply connectors, and a charging controller. The power supply connectors are configured to be received into the charging receptacles to attain connections between the charger and the battery unit. The charging controller is communicably coupled to the charger and is configured to receive an input corresponding to a net charge capacity of the battery unit; determine a power to be supplied to the battery unit by the charger to charge the battery unit in response to the input; and supply the power to the battery unit from the charger through the connections. The power to be supplied to the battery unit corresponds to a maximum possible power that meets the net charge capacity of the battery unit in the shortest possible time.

Abstract: A cable arrangement system for one or more sets of cables to an electric machine is provided. The cable arrangement system includes a terminal box, a compression plate, multiple glands, and a multipoint connector. The terminal box is disposed on a housing of the electric machine and includes a first side having a first set of openings. The compression plate is releasably engaged with the first side and defines a second set of openings axially aligned with the first set of openings. The glands are configured to receive the first set of cables. Each of the glands includes a first and a second portion received in the first and the second set of openings respectively. The multipoint connector is disposed within the terminal box and includes a first and a second set of terminals configured to engage with lugs associated with the first and a second set of cables.

Abstract: The disclosure describes technology that includes a charge-port capture detection mechanism, which has a mounting base and a capture gate. The mounting is connectable to a battery electric vehicle (BEV) at a location adjacent to a high-voltage, direct current (HVDC) charge-port. The capture gate is movably attached to the mounting base, the capture gate being moveable, relative to the mounting base, between a closed position in which the capture gate captures a charge connector of a charging cable engaged in the HVDC charge-port and an open position.

Abstract: An electric machine and method for powering the electric machine using interchangeable power modules that are configured to be interchangeably placed within power bays of the electric machine is disclosed. The electric machine includes an electrical module that is configured to receive power from one or more of the power modules placed in the power bays and transform, such as from DC to multi-phase alternating current (AC), and provide the power to one or more motors of the electric machine. The power modules may be of the same dimensions, same electrical interfaces, and/or same power output (e.g., type, magnitude) as each other to enable the interchangeability of the power modules. The power modules may be ones that generate power or ones that store energy. In some cases, the generating power modules may charge the energy storage power modules, while the energy storage power modules power the electric machine.
