Hubject

Digital networking through new e-mobility platform

Since the end of 2017, a new IT system has been available to all partners in the shop network of Hubject. The platform, developed in partnership with Qualysoft, now connects more than 300 automotive companies, utilities and IT companies in 26 countries, providing the foundation for the world's largest cross-provider charging network for electric cars: the intercharge network. With the new development of its platform, Hubject is preparing for the market ramp-up and the increasing digital networking of electromobility.

As electric car drivers can always charge anywhere: this is the mission of Hubject. This becomes reality through the company's open eRoaming platform. The success of electric powertrains has resulted in significantly higher utilization of the JV's IT system, which has recently announced its expansion into China and the US.

The innovative platform was implemented in cooperation with the Austrian IT company Qualysoft. The 25-strong international project team started the development of the highly complex system in May 2017.

The first additional value-added services are already available with the rollout of the new platform. In view of the increasing share of volatile renewable energy sources, electric vehicles can contribute to the stabilization of electricity grids. Intelligent energy management systems stabilize imbalances in the power grid through a combination of intermediate storage and energy recovery. This need for flexibility will also be reflected in the prices of charging electric vehicle charging. For this reason, the platform will support dynamic price management for charging station operators in the future. This enables the function to dynamically price the charging current provided depending on the time of day and the availability of your energy sources. In this way, new incentives for the use of renewable energy can be created for the customer.

Another barrier to the use of charging stations should soon be solved with Hubject's new platform: the different quality of geodata provided by charging station operators. The Hubject system now allows the evaluation of charging stations of different operators by the electric car driver. This allows them to plan their routes more reliably by detecting and avoiding charging points with incorrect information.

All functions are supported by a newly designed, user-friendly user interface, which will enable even users without specialist knowledge to use it intuitively on stationary and mobile devices.

The Project


Project Duration:

01.05.2017 - 31.12.2017


The Hubject eRoaming Platform 2.0 (HeP 2.0) connects CPOs (charging point operators) and EMPs (providing EVs and charging cards) to enable cross-partner charging. HeP Version 1.0 was the world's leading e-mobility broker system, where all requests were processed, stored and answered by a centralized system. Due to the architecture and the non-functional requirements, the system already reached its first performance limits in 2016. Requests could not be processed fast enough and especially loading sometimes suffered from the delay. Therefore, the project HeP 2.0 was launched.

The aim of the HeP 2.0 project was to replace HeP 1.0 with a scalable, globally available cloud solution. In general, HeP 2.0 is a functionally similar solution to HeP 1.0, but parts of the solution were also redesigned. When developing HeP 2.0, the latest version of the Intercharge protocol had to be implemented again. This protocol defines the interface between EMP, CPO and Hubject. That it defines the interface that users of the HeP platform must implement. The support of the existing protocol was necessary so that the 300+ platform participants can easily be switched to HeP 2.0 on their side. In addition to the existing protocol version, a new version with additional features and detail improvements has been implemented. Nevertheless, the main difference between HeP 1.0 and HeP 2.0 is in the technical solution. To meet the enormous scalability and performance demands of the e-mobility boom, a distributed, highly scalable solution needed to be implemented.


In summary, there were the following main project goals:

  • New development of HeP based on a highly scalable cloud architecture
  • Full support of the existing intercharge protocol
  • Further development of the Intercharge protocol with new features such as Dynamic Pricing
  • Efficient data processing even under high load
  • High security standards through certificate-based security and 2-factor authentication
  • Cross-service logging and aggregated system monitoring
  • Simple, independent expansion and maintenance through loosely coupled microservices
  • Automated deployment of the entire platform to support new markets or white-label to offer solutions


The implementation of the project was carried out using SCRUM in 2-week sprints. The project was divided into two phases: the creation of a proof of concept and the implementation of the MVP. The project, which employed up to 20 people, was launched on 1 May 2017, and HeP 2.0 went into operation successfully on 22.11.2018. Since then, Hubject partners and customers have been able to use the new, high-performance platform for cross-provider charging of their electric cars.

Advantages for the customer


sales increase

With the high scalability and performance of the HeP 2.0 platform, Hubject is able to keep pace with the tremendous growth of the e-mobility market and the increasing adoption of EVs: from 2016 to 2017, new registrations of EVs have doubled. Thus, the platform directly supports the associated increase in sales.


process improvements

An improved user experience for both Hubject maintainers and end users significantly improved interaction with the HeP 2.0 platform. For example, a newly designed wizard guides you through the initial login on the platform. The creation and processing of bi-lateral contracts has also been simplified and improved.


productivity and efficiency increase

Both the development of the platform as well as the operation and maintenance have been significantly simplified. With automatically scalable microservices and detailed monitoring of the AWS cloud, the platform runs safely, efficiently and cost-effectively. Working with the platform itself was also simplified by the newly developed web portal.


organizational improvements

The new development of the portal better supports the existing organization of the customer. In HeP 2.0, user grants can be granted in a finely granular manner in order to best represent the existing organizational responsibilities. In addition, the onboarding process has been significantly streamlined and accelerated by automation.


strengthening the market position

Hubject is Europe's leading eRoaming provider. The new platform further strengthens this position and Hubject is thus establishing itself as an innovation leader in its field. The IT system connects over 300 partners and is thus the foundation of the world's largest provider-wide charging network for electric cars: the intercharge network.


improving innovation
  • Massive increase in performance (request / response time)
  • Facilitation of maintenance and extension
  • New designed portal for HeP 2.0
  • Highly scalable, extensible cloud architecture
  • Fully automated creation of new HeP 2.0 environments
  • easy expandability to tie in future innovations


qualification of employees

Through the project, the client was able to build up qualifications in the area of "Software Operation in the Cloud" and "Advancement of Micoservices". Due to the high demands in terms of scaling and performance, our experts have also acquired further qualifications in this area. In addition, Qualysoft has built up deep sector-specific expertise in the area of e-mobility.


satisfaction and acceptance

The new platform was already anticipated by many customers, which was very quickly given wide acceptance. This impression was reinforced by the new, user-friendly portal and seamless migration. Customers appreciate the ease of use and the resulting efficiency gains. The increased performance of HeP 2.0 was also enthusiastically received.


aquire new markets

The platform's increased performance and cloud operation enable Hubject to easily enter new markets with HeP 2.0. For example, a pilot is planned in North America. For this purpose, HeP 2.0 can easily be used to set up and operate a new dedicated instance for North America. The simplified onboarding of new partners also supports the conquest of new customers / markets.
