Abstract: A system and a method operate in a first mode and a second mode. In the first mode, the system and the method control the direct current and the quadrature current applied to an internal permanent magnet motor to achieve a desired rotational speed and a desired torque over a range of internal operating temperatures of the motor without exceeding a maximum stator current. If a calculated stator current exceeds a maximum stator current, the system and the method operate in the second mode wherein the system and the method control the direct current and the stator current to maintain the calculated stator current below the maximum stator current.

Abstract: A system and method for our selectively controlling an operational of a thermal management system of a mobile charging system. Based on satisfaction of one or more predetermined thresholds, the thermal management system can operate in a first, high power mode or a second, low power mode. During operation in the first power mode, electrical power can be supplied from a battery for operation of an impeller that can facilitate an air flow over a heat exchanger. During operation in the second power mode, the impeller can be deactivated, and ram air can instead be used to control at least the temperature of the heat exchanger, thereby conserving electrical power of the battery. The one or more predetermined thresholds can include a ground travel speed of the mobile charging system, which can be determined using information from a location system.

Abstract: Systems and methods are disclosed herein for automatically planning the workday of a battery unit powered electric work vehicle. The vehicle includes a chassis supported by traveling devices, itself further supporting a work implement. A battery unit discharges energy for at least assisting with actuation of the traveling devices and/or work implement. A controller receives input data from a user regarding specified missions to be performed by the work vehicle in a given period of time, and predicts rates of energy consumption for at least one operating mode corresponding to each remaining mission to be performed. The controller further generates, to a user interface, output data corresponding to a required charge state of the battery unit based on the predicted rates of energy consumption, relative to a detected current charge state of the battery unit. The controller may monitor activity and/or consumption rates throughout the day and proactively generate outputs for, e.g., usage optimization.
