Method for controlling a line converter on board a track-bound vehicle
In a method for controlling a line converter on board a track-bound vehicle semiconductor devices of current valves of the line converter are controlled to be turned on and off so as to prevent the current (I) through a secondary winding of a transformer to which midpoints of phase-legs of the converter are connected to pass zero and shift direction other when the voltage across the secondary winding shifts direction by a start of a new half period of an AC line voltage across the windings of the transformer.

Mobile charging for electric vehicles
Example methods, apparatus and articles of manufacture for mobile charging of an electric vehicle are described herein. An example electric vehicle includes a battery and a first charge interface for the battery disposed on an exterior surface of the electric vehicle. The first charge interface is configured to be engaged with a second charge interface on an articulating arm of a mobile charge vehicle to transfer energy from an energy source of the mobile charge vehicle to the battery while the electric vehicle is in motion.
Dynamic control for light electric vehicles
A method for dynamic control of an electric vehicle operable based on a throttle value received from a throttle and a default throttle map correlating default output values with throttle values, the method including: determining a user parameter; detecting a condition indicative of perturbation; in response to detecting the condition indicative of perturbation, determining a replacement output value for a first throttle value based on the user parameter; and controlling vehicle operation to meet the replacement output value in response to receipt of the first throttle value.
Light electric vehicle that supports the weight of a user
A method for a light electric vehicle that supports a weight of a user that includes the steps of supplying a support surface to support the weight of a user; supplying a motor controller containing a processor to control operation of an electric motor mounted i) on the support surface, or ii) proximal to the support surface, where the motor controller and its processor are electrically connected to the rechargeable electric battery, where the electric motor is electrically connected to the motor controller and the rechargeable electric battery, as well as connected to a drive mechanism to drive one or more wheels; and supplying a mode selector to set a first riding-experience mode for the light electric vehicle, wherein the first riding-experience mode has a first acceleration maximum and a second riding experience mode has a second acceleration maximum.
ELECTRIC UTILITY VEHICLE DRIVELINE RECHARGING
An agricultural/utility vehicle has as its motive power source one or more electric motors supplied by one or more rechargeable batteries to drivingly rotate a shaft of the vehicle driveline. To recharge the batteries, an external power source is applied to cause the driveline shaft to rotate, resulting in at least one of the electric motors acting as a generator to recharge the batteries. The external power source may include a source of fluid pressure that drives a hydraulic pump of the driveline as a hydraulic motor. The external power source may be an external source of rotational energy coupled to a power take-off shaft of the vehicle.

DYNAMIC INDUCTIVE WIRELESS POWER TRANSMITTER SYSTEM WITH A POWER TRANSMITTER MODULE
A method for a dynamic inductive wireless power transmission includes providing an AC/DC power converter that receives three-phase power and provides regulated DC output current, connecting a trunk cable to the AC/DC power converter output and to multiple power transmitter modules. The trunk cable connects inputs of the power transmitter modules in series. The power transmitter modules transmit inductive wireless power over an air gap. The method includes providing a system controller that detects a vehicle containing a receiver coil and confirms if the vehicle should receive the inductive wireless power from the multiple power transmitter modules, and includes configuring the system controller to communicate with the AC/DC power converter to maintain the regulated DC output current at a constant value and transmit the inductive wireless power to the vehicle through the multiple power transmitter modules when the vehicle should receive the inductive wireless power.
