EV Charging Platform

The developed application is an EV charging network for fast and easy access to certified charging stations.

It has been developed having three levels of application: mobile application and private office - for end users, owners of electric cars; backoffice - for partners, who own charging stations; supreme office - for the owners of the whole system.

Challenges

Develop a durable platform architecture from scratch to be able to serve millions of users.
Provide the ability for EV owners to reserve time slots for charging and to be sure that EV stations are available at this time.
Connectivity for HORECA businesses.
Bind together known charge point protocols and synchronize them to a single control server.

Our Approach

In order to control all reservations the Embrox Team created a separate independent que server that collects requests, puts them in que and turns charging points on/off. The additional system was also developed for updating charging stations availability. For the end user's convenience EV stations are presented in different ways: on the map, as a list, grouped by categories. Also users can filter stations when they want to find the most suitable option for them. To be able to cover all known EV protocols, the Team has developed all versions of OCPP servers from scratch. Also, in order to be open and flexible to 3rd party partners, the development team has implemented an OCPI protocol which allows controlling charging points from anywhere. For a business that owns charging stations, a powerful dashboard tool was developed. It represents a web application for managing, controlling access to stations, reviewing analytical information and handling their billing data about charging transactions.

Results

Embrox developed a scalable system that binds all users and businesses together in one ecosystem.

As a result, the platform integrates more than 12,000 EV stations across the world and this number is growing.

The mobile applications help EV drivers build their routes through available charging stations at minimum time expenses. At the present time the platform’s partners can propose some of their additional services and attract new customers. From users' and partners' perspective the ecosystem is growing pretty rapidly, 10,000+ installs on Google Play Market confirm that.

What Our Team Says

Daria Ostapenko

Mobile Developer

This project was carried out by us for quite a long period of time, so it managed to occupy a significant place. The project was interesting because the digitalization of electric charging services was just starting to gain momentum at that time. Therefore, it was awesome to work on the project, the topic of which was at the hearing. We had to learn a completely new communication protocol between the charging stations and our system at the beginning of our work on the project. Now when you see charging, you don't just push buttons, but you seem to understand what language it communicates with.
