Abstract: A work machine using a direct current power system that isolates reactive loads is described herein. The work machine uses a machine power distribution unit that receives direct current power from two or more battery banks of a power unit, whereby each of the battery banks deliver electrical power on a separate direct current bus. A machine power distribution unit of the work machine receives the electrical power from the battery and is used to isolate the power using bus connectors. One of the battery banks provides power to one direct current bus of the work machine and another battery bank provides power to another direct current bus of the work machine. A reactive load serviced by one of the battery banks is electrically disconnected from another reactive load serviced by the other battery bank.

Abstract: An example on-board charger includes an insulating housing and an on-board charging device. In the on-board charging device, a bidirectional direct current conversion circuit is configured to receive a first direct current transmitted by a direct current bus, and output a second direct current through a power battery connection port to supply power to a power battery. A first bridge arm circuit is configured to receive an alternating current through an alternating current power supply input port, and output the first direct current. A second bridge arm circuit is configured to receive the first direct current and output a second alternating current through the alternating current load power supply port to supply power to the alternating current load.

Abstract: Embodiments include an EVSE unit having a Level 2 or Level 3 charge handle, a receptacle configured to receive the Level 2 charge handle, and a current overage protection unit. The EVSE unit can include a Level 1 outlet including one or more plug outlets configured to receive one or more corresponding Level 1 plugs. A first power meter associated with the Level 2 charge handle can meter power delivered via the Level 2 charge handle. A second power meter associated with the Level 1 outlet can meter power delivered via the Level 1 outlet. A charging logic and relay section can intelligently allocate power between the Level 2 handle and the Level 1 outlet according to charging rules. The current overage protection unit can ensure compliance with local ordinances and protect internal components of the EVSE unit.
