  • Patent number: 9104443
    Abstract: A method is provided for creating custom control software for a particular propulsion system configuration. Generic control software is provided that is configurable for use with a plurality of different propulsion system configurations. The generic control software is generically designed to control each of the different propulsion systems regardless of their different propulsion system configurations. The generic control software comprises a plurality of programmable arrays (or configuration tables). Information that characterizes a particular propulsion system configuration of the plurality of different propulsion system configurations is input into the programmable arrays to configure the generic control software into custom control software that is customized for use and designed to operate with the particular propulsion system configuration.

  • Patent number: 8878495
    Abstract: Systems and methods are provided for an electrical system. The electrical system, for example, includes a first load, an interface configured to receive a voltage from a voltage source, and a controller configured to receive the voltage through the interface and to provide a voltage and current to the first load. The controller may be further configured to, receive information on a second load electrically connected to the voltage source, determine an amount of reactive current to return to the voltage source such that a current drawn by the electrical system and the second load from the voltage source is substantially real, and provide the determined reactive current to the voltage source.

  • Patent number: 8330293
    Abstract: A charging system of the present invention is connectable to a power grid having a monitoring device. The monitoring device monitors the power delivered to a plurality of loads and determines a power factor and a power factor correction value associated with the loads. The power factor correction value indicates the difference between the power factor and unity. The charging system includes an electrical device, a charger in communication with the electrical device, a charging controller, a power factor correction circuit, a communication device, and a controller. The communication device of the charger receives a data signal from the monitoring device indicative of the power factor correction value associated with the plurality of loads. The power factor correction circuit is configured to communicate an input current to and from the power grid, which adjusts the power factor of the associated loads to about unity.
