Abstract:
An energy management system comprises an energy management module that electrically connects an energy storage system of a vehicle with a traction link of the vehicle, the traction link being electrically connected to a traction motor. The energy management module is configured to deliver electrical power from the energy storage system to the traction link during a haul route, according to a discharge rule that is selected by a comparison of predicted performance of a plurality of discharge rules to a baseline performance of the haul route, in which electrical power is not delivered from the energy storage system to the traction link, in order to obtain fuel savings, speed excess, or a combination of fuel savings and speed excess relative to the baseline performance.
Abstract:
A system to optimize performance of a powered system, the system including a data device configured to provide current information about current operating conditions of the powered system and/or prior information about the powered system, a controller configured to control operation of the powered system, and a processor configured to provide at least one control command to the controller for use in operating the powered system and/or user information with at least one recommended command to a user to control the powered system, wherein the at least one control command and/or user information are based at least in part on the current information and/or the prior information. A system and computer software code, stored on a computer readable media and executable with a processor, are also disclosed.

Abstract:
A system includes a retarder in electrical communication through an electric link with an alternator, and a controller that compares a power measurement with an accessory load on a system during a retard event, and can reduce an electrical load on the alternator, or can remove all electrical loads from an engine, when electric power that is generated from the retarder is measured to be greater than an accessory load on the system. The system may include an alternator that provides a motor function to rotate a shaft coupled to an engine that is mechanically coupled to one or more mechanically drivable accessories. The alternator powers the mechanically drivable accessories in place of or in addition to the engine.

Abstract:
Systems and methods are provided to measure a voltage across a two-state dipole. The systems and methods measure voltages across two measurement paths of operational circuitry at first and second sensor terminals. The operational circuitry is configured to decouple the first and second sensor terminal based on a dipole voltage. The systems and methods further estimate the dipole voltage based on the voltages of the two measurement paths.
