An Integrated Motor Drive and Battery Fast Charger Station for Plug-in Vehicles

Paper in proceeding, 2013

Vehicles using grid power to charge the battery are parked during the charge operation. So, there is a possibility to use the traction components in the charger circuit to reduce the size, weight, and cost of charger. Charging power level directly is related to the charging time that is a crucial limiting factor in enhancement of plug-in vehicles. An integrated fast charger station is described that vehicle traction components are used in the charger system to provide a cheap charge solution. An isolated stationary transformer provides electric power or the vehicle inverter to constitute a boost rectifier serves as the battery charger. The system structure, components and operation is described in this paper. Moreover, a small scale laboratory setup is developed to practically verify the idea. The practical system is based on NI CompactRIO platform.
