Integrated motor drive and battery charging system for a hybrid vehicle

Start date 01/04/2008
End date The project is closed: 31/05/2013
For vehicles using grid power to charge the battery, traction circuit components are not engaged during the charging time, so there is a possibility to use them in the charger circuit to have an on-board integrated charger. The aim of this project is to propose, develop and construct an isolated high power integrated charger based on a special electrical machine with a double set of stator windings. By reconfiguration of the motor stator windings in the charging mode, a six-terminal machine is achieved. The so called motor/generator acts as an isolated three-phase power source after synchronization with the utility grid in the charging mode. This rotary three-phase isolated power source constitutes a three-phase boost rectifier (battery charger) with full utilization of the inverter. The motor windings are reconfigured by a relay-based switching device for the charging and traction modes. A 4 pole 25 kW interior permanent magnet machine is used in the experimental system with a possibility to reconnect the windings for charging.
This sub project is part of the ‘‘Electrical System Design of PHEVs” project inside Swedish Hybrid Vehicle Centre (SHC). The project includes three parallel sections addressed by three parallel groups together at Chalmers, KTH and Lund: Motor Design and Sensorless control (KTH), On Board Integrated Charging (Chalmers) and EMC design (LTH).
