Abstract : Among the challenges that slow down electric vehicle proliferation, one major factor is technological and progressive features associated with charging infrastructure. This paper presents the development and implementation of electric vehicle charging communication test-bed following the globally accepted charging communication standard “CHAdeMO”. The developed test-bed has software and hardware modules for CHAdeMO message passing that helps in achieving communication of electric vehicle with the charging infrastructure. Graphical user interface created in MATLAB mimics electric vehicle and electric vehicle supply equipment and CAN module of vehicular network toolbox in MATLAB is used for data exchange in accordance with CHAdeMO standard in software. The hardware implementation is achieved using Arduino mimicking electric vehicle and electric vehicle supply equipment and MCP2515 CAN controller for message passing. The test-bed demonstrates different stages of message passing as per CHAdeMO standard both in software and hardware. In addition to fulfilling the purpose of a test-bed for electric vehicle charging communication the setup can also be used as a teaching tool for CHAdeMO protocol. The test-bed can be further extended by implementing message passing using other charging standards such as GB/T or CCS and other wired and wireless communication protocols.
