The method includes receiving a requested torque for the electric motor, calculating a pulsed system efficiency, calculating a continuous system efficiency, and operating the electric motor in the pulsed mode when the pulsed system efficiency is greater than the continuous system efficiency. The pulsed system efficiency is calculated for delivering the requested torque from the electric motor in a plurality of torque pulses greater than the requested torque. The continuous system efficiency is calculated for delivering the requested torque from the electric motor as a continuous torque. The system efficiency may be at least partially based on a battery efficiency and a motor efficiency.

摘要： A power driving system for an electric vehicle with a motor includes plural battery boxes, a first DC bus, a second DC bus and a power converter. The first DC bus is electrically connected with the battery boxes for selectively receiving electric energy from the battery boxes. The second DC bus is electrically connected with the battery boxes for selectively receiving electric energy from the battery boxes. The power converter is connected between first DC bus and the second DC bus. After the power driving system is changed from a steady state power mode to a driving voltage switching mode, a driving voltage switching process is performed. By the power converter, a voltage of one of the first DC bus and the second DC bus in a steady state is used to adjust a voltage of the other of the first DC bus and the second DC bus.

摘要： An electrical control system having a direct current to direct current regulator receiving a direct current supply input, wherein the regulator outputs a controlled voltage direct current inverter power feed. Included is an inverter in electrical communication with the regulator and receives the controlled voltage direct current inverter power feed, the inverter outputs an alternating current motor power feed to a permanent magnet brushless direct current motor that outputs a shaft rotational speed and a back electromotive force. Also, a control is provided for regulating the controlled voltage direct current inverter power feed based upon criteria utilizing the back electromotive force or an auxiliary motor stator wire loop signal in conjunction with an optional voltage look-up table to substantially make the controlled voltage result in a reduction of a pulse width modulation switching frequency to further smooth and reduce harmonic of the alternating current waveform to increase motor efficiency.

摘要： A speed control device for use in a battery-powered vehicle wherein a shunt field current in a compound electric motor for driving the vehicle having a reactor connected in series therewith can be selectively controlled by using a variable resistor included in the circuitry and operatively interconnected to an accelerator pedal so that the resistance to the shunt field current may be changed accordingly to the extent of stepping-down on the pedal by the operator. The speed control device also features that a part of the vehicle's body structure of a ferro-magnetic material is used in combination as a core of the reactor so as to form a complete magnetic circuit for the reactor.

摘要： The method is especially suitable for two identical groups of elements, and for supplying a continuous current traction motor. The commutating means modifies the coupling of groups of elements from parallel to series and conversely, as a function of the power demanded for driving the motor. The current supply of the motor is ensured by pulses delivered by a chopper type device monitored as a function of the power demanded. The commutating means e.g. a thyristor are actuated in synchronism with the operation of the chopper type device.

摘要： A battery vehicle having a normal speed range for house to house deliveries and an extended speed range for lengthy journeys such as to and from delivery rounds. The extended speed range is engageable by operation of a manual range control. The manual range control is rendered inoperative on startup so that the extended speed range is not immediately available. After a delay, of predetermined period, or after a delay of predetermined period during which the speed has been held at, or above, a determined limit, or after the vehicle has covered a predetermined distance, the manual range change is enabled.
