Abstract
With a growing trend of electrification of vehicles there is a need for more flexible and advantageous charging options that reduce EV limitations. To overcome these limitations, dynamic charge through Electric Road Systems (ERS) is in development, and fast
charging stations are being deployed all over the world.
This thesis focuses on combining the use of both technologies, attempting to use an ELONROAD ERS module for static fast charging, through the CHAdeMO protocol.
The slightly modified ELONROAD module used only has three physical contacts, used for power connections (positive, negative and protective earth), required communication signals have to be sent wirelessly. The thesis’ solution is divided into two independent systems. The... (More)
With a growing trend of electrification of vehicles there is a need for more flexible and advantageous charging options that reduce EV limitations. To overcome these limitations, dynamic charge through Electric Road Systems (ERS) is in development, and fast

This thesis focuses on combining the use of both technologies, attempting to use an ELONROAD ERS module for static fast charging, through the CHAdeMO protocol.
The slightly modified ELONROAD module used only has three physical contacts, used for power connections (positive, negative and protective earth), required communication signals have to be sent wirelessly. The thesis’ solution is divided into two independent systems. The first one, responsible for wireless CHAdeMO communication, according to IEEE standard, involves CAN and four analog signals. The second, is in charge of
detecting EV position and establishing a proper charger-vehicle connection through the road. To verify the functions of both systems, two experimental tests are conducted. The tests carried out are designed to be independent and a proof of concept of the complete prototype.
The communication subsystem is proved to be a working CAN-to-CAN gateway, and capable of sending the other electric signals, despite that ijavascript:deleteRecord('au_3')t is not fully compatible with
CHAdeMO. More experimental studies with the charger, some already designed, need to be performed. The switchbox subsystem is able to recognise the orientation as well as position of the vehicle, switching connections accordingly.
All things considered, with some alterations to the verification process of the communication, the overall solution is strongly believed to be fully working. (Less)
