Vehicle Characterization for Unidirectional Charging Management

EV charging control can be achieved by directly accessing the EV controller via charging station (EVSE). In this project, a Phoenix Controller is used inside a Leviton EVSE with Modbus via Ethernet interface to control several EVs. The EVs tested are Scion IQ, Chevy Volt, and BMW Mini-E. They are tested and characterized in terms of supporting unidirectional grid services.

  • Microgrid integration of plug-in electric vehicles (PEVs) requires analysis of individual charging control dynamics of different PEV models under various charging/discharging control commands.
  • At Energy Storage Laboratory (ESL) of NREL, different PEVs are tested to understand their dynamic response characteristics when charged/discharged by the grid. PEVs are connected to the grid using a Leviton EVSE that is modified and remote controlled using a Phoenix controller as shown in Figure on the left side. 
  • The EVSE is controlled using Modbus protocol utilizing the Ethernet connection of Phoenix controller inside the Leviton EVSE. The controller accepts integer values of reference current starting from 6 A to the rated current of the on-board charger.
  • The results of the tests and the developed models are shown above.
