Telekom Slovenije and ELES and their partners developed an advanced remote-operated solution for efficient mass charging of electric vehicles that ensures the stability of the power distribution system.
The solution is part of the E8 concept of integral development of infrastructure for mass charging of e-vehicles. Telekom Slovenije, ELES and NGEN held a live demonstration for business customers showing how this system-based approach provides a carbon neutral solution for charging their e-vehicle fleets at the lowest prices. This is the first such demonstration in Slovenia.
With the growing number of e-vehicles on Slovenian roads, the needs for charging stations are also on the rise, and it is also important that Slovenia sets up a network of intelligent e-charging stations at private locations, providing users with an affordable way to charge an increasing number of e-vehicles. The most cost-efficient way for charging e-vehicles is by plugging them in for a longer time, and while they are charging, they contribute to the regulation of production and use of electricity. To put this in a more concrete example: when the power distribution grid is faced with an unplanned difference between the supply and the demand for electricity, the network operator (ELES) requests assistance from the selected provider of system services (NGEN) in balancing out the system. The system service provider uses electric vehicles connected to e-charging stations (in this case at Telekom Slovenije’s and ELES’s locations) that support remote power management in the scope of the currently available minimum to the maximum charge.
Telekom Slovenije and ELES utilise advanced software for intelligently managing e-charging stations, ensuring remote multi-level charging management (e.g. Ocean, Etrel). In the long term this infrastructure will also support the vehicle-to-grid (V2G) concept, where e-vehicles will be able to act as electricity storage units, and release power into the grid when needed.
“Even though the solutions that we demonstrated live today are logical, and have proven popular among experts, ELES has spent years looking for partners who would be ready to connect a series of building blocks while taking into account the international standards of ICT connectivity. I am happy that we share the same vision as Telekom Slovenije and NGEN. With the increase in the prices of electricity that we are facing right now, charging utilising the E8 concept, which will be marketed by Telekom Slovenije from now on, allows us to offer prices significantly below the stock-market average, to activate new users and to accelerate the electrification of all types of vehicles,” emphasised Uroš Salobir, MS, director of Strategic Innovations at ELES.
“With advanced solutions for mass charging of e-vehicles it is key to have a reliable and secure information-communication infrastructure that supports even the most complex solutions, tailored to the needs of an individual industry or ecosystem, such as e-mobility. The fifth generation of mobile networks (5G) supports network slicing for the introduction of virtual campus networks, which means that virtual dedicated networks can be set up for individual verticals within a single physical infrastructure. The solution that we will soon be offering as a turnkey service on the market for purchase or leasing will have several levels of management. This is a new step towards the digitalisation of the society and creating a zero-carbon society,” said Tomaž Jontes, vice president of the Management Board of Telekom Slovenije.
Solutions for mass charging of e-vehicles from Telekom Slovenije and ELES are developed to operate in accordance with E8, the concept of integral development of infrastructure for mass charging of e-vehicles, focusing on a friendly future through the use of electric vehicles for reducing CO2 emissions. This is also in line with the European Union’s so-called green goals, and supports the activities of the Republic of Slovenia in achieving its environmental goals.
