  • Publication number: 20220024318
    Abstract: A machine may a first high voltage interlocking loop (HVIL) system to provide power to one or more components of the machine, the first HVIL system comprising: a plurality of groups of batteries; a plurality of disconnect components connected to the plurality of groups of batteries; a plurality of sets of contactors, a set of contactors, of the plurality of sets of contactors, being connected to a group of batteries of the plurality of groups of batteries. The machine may a second HVIL system to receive power from a power source, the second HVIL system comprising: a port configured to receive a connector of the power source and receive power, from the power source via the connector, to charge the plurality of groups of batteries, wherein the second HVIL system is independent with respect to the first HVIL system.

  • Publication number: 20210273466
    Abstract: 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.

  • Patent number: 7714587
    Abstract: 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.

  • Patent number: 7626396
    Abstract: Systems and methods are disclosed for compensating electrical leakage and detecting balanced electrical leakage for a machine hosting an HV system. In one embodiment, a fault detection and compensation system includes a DC power supply electrically referenced to a machine frame, a leakage correction switch connected to the machine frame, a current source controlled by the leakage correction switch, and a voltage measuring device that measures an offset voltage reflecting whether the HV system is in an unbalanced fault condition. 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 correction switch and the current source.
