What is

Evroaming is a European-based company that specializes in the development and operation of electric vehicle (EV) charging networks. The company was founded in 2012 and is headquartered in Austria.
Evroaming's primary focus is on building and operating interoperable charging infrastructure, which allows EV drivers to easily charge their vehicles at any compatible charging station within the network. This means that EV drivers can use the same charging card or app to access charging stations from multiple charging network operators, making it easier and more convenient to travel longer distances.
In addition to operating its own charging network, Evroaming also offers its technology and services to other charging network operators to help them develop and maintain their own interoperable charging networks. This approach has helped to promote the widespread adoption of EVs and accelerate the development of EV charging infrastructure across Europe.
Overall, Evroaming is playing an important role in the transition to a more sustainable transportation system by helping to build a reliable and accessible EV charging network across Europe.
For example, you use a cellular connection (mobile phone). When you travel by train to another country, your operator does not have their own towers there. But your phone still works as soon as the plane lands in another country =)
Yes, it is roaming. You can just as well receive calls, answer SMS and surf the Internet, and all this without the additional stress associated with purchasing a new SIM card =)

Similarly, roaming is implemented for electric vehicles. It allows drivers to charge seamlessly at stations belonging to different networks. Let's take a closer look at how EV roaming works and what it means for your business.

OCPI (Open Charge Point Interface) is an open protocol for communication between different electric vehicle charging networks. It was developed by the Open Charge Alliance, a non-profit association focused on creating an open and transparent ecosystem for electric vehicle charging.
OCPI defines a standard set of APIs (Application Programming Interfaces) that allow different charging networks to communicate with each other in a standardized way. This means that users can easily access and use charging stations from different networks, without needing to create a separate account for each one.
The protocol supports a range of functionalities, such as real-time status updates, pricing information, and remote control of charging stations. It's designed to be flexible and extensible, so that it can be adapted to the specific needs of different charging networks.
OCPI is compatible with other electric vehicle charging protocols such as OCPP (Open Charge Point Protocol) and ISO 15118, and is increasingly being adopted by charging network operators around the world. By creating a standardized way for different networks to communicate and interoperate, OCPI helps to make electric vehicle charging more convenient and accessible for users, while also promoting competition and innovation in the industry.

Back-to-back integration refers to the scenario where two charging networks are directly connected to each other, without a central hub or intermediary platform.
To achieve back-to-back integration using OCPI, each network must have an OCPI implementation that allows it to communicate with other networks. The networks can then exchange information such as availability, pricing, and status updates in real-time, using the OCPI APIs.
Back-to-back integration can help to improve the reliability and efficiency of electric vehicle charging, by enabling seamless access to charging stations from different networks. It can also help to reduce the cost and complexity of setting up a charging network, by eliminating the need for a central hub or intermediary platform.
Overall, OCPI is a flexible and extensible protocol that supports a range of integration scenarios, including back-to-back integration, and is increasingly being adopted by charging network operators around the world.
Here's how Evroaming works in more detail:
  1. Interoperability: Evroaming's platform provides a standard protocol for charging station communication and data exchange between different charging network operators. This enables EV drivers to access any charging station within the network using a single account, regardless of the charging network operator.
  2. Roaming agreements: Evroaming negotiates roaming agreements with charging network operators to allow their customers to access charging stations in other networks. This allows EV drivers to travel further without worrying about the availability of charging stations.
  3. Billing and settlement: Evroaming's platform handles billing and settlement between charging network operators, ensuring that customers are charged the correct amount for their use of charging stations in different networks.
  4. Software integration: Evroaming's software integrates with the backend systems of charging network operators, enabling them to manage their charging infrastructure, monitor usage, and generate reports.
Overall, Evroaming's technology enables interoperability and roaming between different EV charging networks, making it easier for EV drivers to access charging stations and travel longer distances. The company's platform also provides charging network operators with a more efficient way to manage their infrastructure and handle billing and settlement.
