   Battery Charging Using Loosely Coupled Inductive Power Transfer
By O. Stielau; J. Boys; G. Covic; G. Elliot [View]
[Download]

Abstract: Loosely coupled inductive power transfer is used for non-contact charging of batteries in an electric vehicle. A naming convention is proposed to uniquely identify the quantities in a multiple pickup system. Using this convention, three pickup topologies are presented, analysed and compared. The use of multiple pickups, allowing independent charging of batteries is described. Pulse charging, which increases the charge acceptance of the batteries, is implemented.

   Control Design for a Hybrid Flywheel City Bus
By H. Huisman; E. J. F. M. Smits; F. J. M. Thoolen; A. Veltman [View]
[Download]

Abstract: A hybrid drive train has been developed for the propulsion of a city bus. the drive comprises of a small generator to supply the average power need of the bus, a traction machine to convert electrical to mechanical power, and a flywheel for power boosting and energy recovery. The power flow between these systems needs to be closely governed and to guarantee user friendly, safe and reliable operation. A distributed non-linear control system, based on average system models and Linear Quadratic Output Feedback, has been developed and tested. Experimental results of the controlled power system show good agreement with simulations.

   Torque and Stator Flux Control of Induction Motor for Eelectric Vehicle
By K. Jezernik [View]
[Download]

Abstract: In this paper a Direct Flux and Torque Control Scheme (DTC) for Electric Vehicle (EV) Induction motor (IM) drive is presented. The control algorithm utilizes the stator flux as control variable and the flux level is selected in accordance with torque demand of EV’s to achieve the efficiency optimized drive performance. The proposed scheme allows a smooth transition into the field weakening region and the full utilization of the inverter current capability during acceleration or regenerative braking of EV. The advantage of proposed IM torque and flux vector control scheme prevails over this conventional control scheme since no extra speed sensor is used. The another advantage is its simple microprocessor implementation. The drive system, including a 18 kW, 4 pole 6000 RPM, 120 V battery-powered IM and a 30 kVA IGBT inverter, has been applied to a pick up truck. Road test running of the truck has verified that the proposed control strategy is practical.
