Systems are disclosed for providing a work vehicle with a mounted auxiliary power source. The control system of the auxiliary power source may be connected to a communication network of the work vehicle to receive data from various systems of the work vehicle and control and power various systems of the work vehicle.

Systems and methods for charging electric vehicles and for quantitative and qualitative load balancing of electrical demand are provided.

A vehicle includes first loads, a power source, and a processor coupled to the power source. Each of the first loads is configured to generate a fault signal indicative of an occurrence of an action performed by said first load to mitigate a voltage transient event. The processor is configured to, in response to a second different load being electrically coupled to the power source: control a voltage available within the power source based on calibration parameters; and in response to receiving the fault signal, adjust at least one of the calibration parameters.

Methods and systems are provided for charging an onboard energy storage device in a hybrid vehicle depending on vehicle operating conditions. In one example, a method includes charging the onboard energy storage device through a dual clutch transmission via an electric machine positioned downstream of the dual clutch transmission, and controlling a driveline disconnect clutch positioned downstream of the electric machine. In this way, charging of the onboard energy storage device may be conducted under conditions where a speed of the vehicle is either above a predetermined threshold speed, or below the predetermined threshold speed.

A system for coupling a towing vehicle to a towed vehicle and/or for controlling charging/braking by the towed vehicle. The system may include a coupler coupling to the towing vehicle; and first and second tow bars having first and second ends and a rotational joint situated between the first and second ends, the first and second tow bars coupled to the coupler at the first ends and being non-parallel in at least one plane with the second ends located further apart from each other than the first ends. The rotational joint providing for the first and second tow bars to be positioned in an open and a folded position. The second ends of the first and second tow bars are configured to be coupled to the towed vehicle. For charging, a trip distance and charge of a towed vehicle battery is utilized to determine a charging rate for the trip.

An ignition coil includes a first winding, a second winding, and a third winding. A first switch is electrically connected to the first winding. A battery is electrically connected to the first winding. A booster is electrically connected to the battery. A second switch is electrically connected to the third winding. A drive device drives the first switch and the second switch. The drive device turns the first switch from on-state to off-state to allow a secondary current to flow through the second winding, turns the second switch from off-state to on-state to supply an output of the booster to the third winding, and superimpose a second current to the second winding. When a third winding current becomes equal to or greater than a predetermined value, the booster controls such that power generated by the third winding current and an output voltage of the booster is restricted to constant power.

A dynamic energy harvesting and variable harvesting force system is disclosed. A boost converter increases a motor voltage as a motor current associated with the motor voltage propagates through the boost converter thereby generating a boost voltage associated with the changing motor current. A power storage device stores energy harvested by the boost converter when the boost voltage exceeds an energy storage threshold. A controller dynamically adjusts a harvesting force applied by the motor so that the harvesting force is relative to the force applied to the motor. The controller also dynamically adjusts the harvested energy stored by the power storage device by adjusting the charging of the power storage device, ensuring that the boost voltage threshold is maintained. The boost voltage when maintained within the boost voltage threshold enables the power storage device to store the harvested energy without impacting the harvesting force applied by the motor.

A control device of a vehicle integrates an amount of degradation of positive electrode capacity of a storage battery during drive of a first predetermined distance. When an integrated value of the amount of degradation is equal to or larger than a first predetermined value, the control device performs a degradation suppressing control to suppress charging and discharging of the storage battery in a low state of charge range where a state of charge of the storage battery is lower than a predetermined ratio that accelerates degradation of the positive electrode capacity, compared with charging and discharging of the storage battery in the low state of charge range in an ordinary control.

An overhead travelling crane having a horizontally extending crane girder, which can be displaced in a railbound manner along a craneway, and having a crane trolley, which can be displaced along the crane girder and carries a lifting gear for raising and lowering a load. The lifting gear has a suspension structure formed as a cable or chain and the overhead travelling crane has electric drives for movements of the overhead travelling crane. The overhead travelling crane has an energy store connected to the drives to supply the drives with energy.

An aspect includes a battery charging system for a hybrid electric aircraft. The battery charging system includes a generator, a battery system, and a controller. The controller is operable to charge the battery system up to a first charge level based on receiving a first charging current at a power input. An operational status of a gas turbine engine of the hybrid electric aircraft is monitored. The battery system is charged at a second charging current received from the generator driven by the gas turbine engine responsive to determining that the gas turbine engine is in a taxi state, where the second charging current is less than the first charging current. Charging of the battery system is halted based on detecting a transition of the gas turbine engine from the taxi state to an off-idle throttle state.
