Patent number: 11707993Abstract: 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.Type: GrantFiled: July 27, 2021Date of Patent: July 25, 2023Assignee: Caterpillar Inc.Inventors: Jonathan Matthew Baumann, Dustin Craig Selvey, Jason Lee Miller, Alexander C. Crosman, III

Patent number: 11631982Abstract: A portable charger assembly operable to charge a battery system includes a housing defining a hollow space. The portable charger assembly also includes a charging module disposed within the hollow space of the housing. The charging module is adapted to provide power supply to the battery system. The portable charger assembly further includes a base adapted to be coupled with the housing. The base includes a base member including a first portion, a second portion, and a third portion. Each of the second and third portions is inclined relative to the first portion. The base also includes a first base plate fixedly coupled to the second portion of the base member. The base further includes a second base plate fixedly coupled to the third portion of the base member.Type: GrantFiled: February 28, 2020Date of Patent: April 18, 2023Assignee: Caterpillar Inc.Inventors: Andrew B. Robinson, Dustin Craig Selvey, Christian D. Ritchie

Patent number: 7714587Abstract: Systems and methods are disclosed for detecting a faulty ground strap connection for a machine hosting a high voltage system. In one embodiment, a fault detection and compensation system includes a ground strap, a DC power supply electrically referenced to a machine frame, a leakage detection switch connected to the machine frame, a current source controlled by the leakage detection switch, and a voltage measuring device that measures an offset voltage. The fault detection and compensation system further includes a leakage detection and compensation controller that compensates for the unbalanced fault condition by controlling the leakage detection switch and the current source, and determines whether the ground strap is properly connected to the machine frame.Type: GrantFiled: June 29, 2007Date of Patent: May 11, 2010Assignee: Caterpillar Inc.Inventors: Robert Wayne Lindsey, Dustin Craig Selvey, Arthur Wild, Robert Roy Sychra
