| dc.description.abstract | This work covers a modeling of a mode 3 charging station control system under the IEC
61851-1 standard in alternating current for electric vehicles. The simulation makes use of free
software tools, the communication process of the charging station with the electric vehicle is
simulated in order to charge its batteries, the simulation also presents a validation and payment
system to users who wish charge your electric vehicle using RFID technology and through a
graphical interface. All the information about each recharge made will be stored on a free web
server on the Internet and also on a local server as a backup method in case the station does not
have a place that does not have Internet access. It is worth mentioning that this server will have
a database to support all the necessary information such as load history that have been made in
the station. The web server on the Internet will be based on the protocol that charging stations
currently have known as OCPP, the web server will have an interface so that users can access
their personal information, as well as charging history, balance, search for a charging station.
available load in a given geographic area, ability to manage multiple stations, data validation to
allow transactions, real-time information display in web browsers, card and transaction
management. After the simulation process, a mode 3 charging station prototype was made under
the IEC 61851-1 standard at 43 kW, the infrastructure of the charging station allows it to be
located in public places. As safety elements, the station has an emergency button to stop EV
charging, ground connections for the entire electrical system and a differential switch. The
infrastructure of the station also allows it to be scalable, that is to say that in the future another
charging system can be placed with its respective charging connector and thus charge two electric
vehicles simultaneously.
A study of charging infrastructures is carried out in mode 3, which are commonly referred to as
semi-fast charging stations in AC under the IEC 61851-1 standard, while fast charging stations,
which work in DC, are grouped under mode 4 of IEC 61851-23.
To provide security to the station, several cases were simulated in which unsafe conditions could
occur when charging the electric vehicle.
Finally, a communication protocol is implemented between the charging station and a server,
similar to the OCPP communication protocol, stored in the application platform as a Heroku
service. This server has the capacity to manage multiple stations, data validation to allow
transactions, display of information in real time in web browsers and data management such as
users, cards, transactions, etc. | |
