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.

Systems and methods for voltage sensing

A system includes a cooling system having a cooling fluid for cooling an engine and a radiator fan motor; a dynamic braking system configured to supply electrical energy to the fan motor during a braking event; and a controller that is operable to direct the electrical energy from the dynamic braking system to the fan motor to cool the coolant to a predetermined minimum threshold temperature. A method includes switching a vehicle thermal management system from a first mode of operation in which the coolant is maintained at a steady operating temperature to a second mode of operation in which the coolant is cooled to a minimum threshold temperature.

Thermal management system, vehicle and associated method

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.

System, method, and computer software code for optimizing performance of a powered system

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.

System and method for controlling energy usage

A system includes a motor coupled to an energy source and coupled to a hoist pump. During one mode of use or operation, the motor cars receive electricity from the energy source and provide mechanical power to the hoist pump. A method includes directing a motor to mechanically couple to the hoist pump, and directing electrical power to flow from an energy source to the motor, and thereby to control the speed of hoist activity.

Hoist system and method

An electric drive system is provided for use in a vehicle that is operated in environments with stringent emissions and ventilation regulations. In one embodiment, the electric drive system comprises a motor capable of propelling the vehicle and an energy storage device coupled to the motor, and selectively couplable to a catenary line, wherein the catenary line is capable of supplying electrical power to the vehicle and to the energy storage device. Additionally, the vehicle includes a mining device that is operable to be powered by energy from one or more of the catenary line and the energy storage device.
