Slovenia’s energy concept among the priorities in the field of transport and energy plays a central role in the introduction of alternative (low carbon) fuels with an emphasis on electrical mobility. By 2055, the document foresees the achievement of 100% of electrical mobility in personal and public transport, and by 2035 the reduction of greenhouse gas emissions in transport by at least 35% compared to 2005. In line with these objectives (and others not related to transport) by 2035, it is planned to halve the energy use of petroleum products, and by 2055 its complete abandonment.
Methods of charging and type of charging stations
When talking about charging or searching for information on various online and non-online sources, we usually read the terms such as the power of the charging station in kW, the voltage in the charging station in volts (V) and the electric current in amperes (A), the types of sockets and alternating or one-way current. This affects the charging time. The time to charge the empty battery can be slow, 11 to 12 hours, suitable for smaller vehicles, slow, suitable for larger vehicles from 3 to 8 hours, medium speeds up to 3 to 4 hours, fast or super-fast for 1 or a half hour for an empty battery or 10 to 20 minutes of charging up to 50% of the battery by Tesla Super Chargers. With regard to current we are talking about alternating (AC) and direct current (DC). AC streaming is designed for slow and half-fast charging at home, at work and in most public places, while the DC current allows for fast charging. Since all batteries require charging of the DC voltage, the electricity emitted by the power supply must be turned into a DC at some point. The sockets are single-phase or three-phase and special, such as the Tesla case.
In Directive 2014/94 / EU, the following definitions apply:
Usually a charging point – means a charging point which allows the transmission of electric power to an electric vehicle with a power of less than or equal to 22 kW, with the exception of devices with a power output of less than or equal to 3,7 kW, which are installed in private households or which original purpose is not charging of electric vehicles and which are not accessible to the public.
High power charging station – means a charging point that allows the transmission of electricity to an electric vehicle with a power exceeding 22 kW.
Charging stations according to the type can be defined as: ordinary charging station, smart charging station, private charging station, half-private and public charging station, wall charging station, charging station on the bar, freestanding charging station.
International standards and regulations play a key role in facilitating the large-scale introduction of electric vehicles and are important in removing technical barriers that can distort the market.

E-charging stations in Gorenjska
At the beginning of 2017, there were 24 e-charging stations in Gorenjska, the majority of which were located in the municipality of Radovljica. Here, we must say that two out of five are located along the A2 / E61 motorway by Petrol at OMV gas stations, North and South. These chargers are two of the four fast charging stations in Gorenjska. Two are located in the municipality of Šenčur at petrol stations Petrol, also along the A2 / E61 motorway Voklo, East and West. At the end of 2017 there were 37 e-charging stations in Gorenjska. The number of e-charging stations is increasing. To update information on the number of charging stations and technical specifications, we invite you to participate. Please provide us with information about newly installed electric charging stations in Gorenjska to e-mail: firstname.lastname@example.org or telephone number 04 28 17 242 or via the E-HUB form.

What is the interoperability of electric charging stations?
»The term was originally defined for information technology or system engineering services that enable the exchange of information. “(Institute of Electrical Engineering and Electronics.) IEEE Standard Computer Dictionary: IEEE Collection Standard Computer Dictionaries. New York, NY: 1990)
»The task of building coherent services for users when the individual components are technically different and managed by different organizations« (Willium y Arms 2000 (sfifa Iqbal)
In the web dictionary, we find the following interpretation for interoperability:
- The ability of computer systems or software to share and use information.
»Interoperability between devices from different manufacturers«
- The ability of military equipment or groups to interact with each other.
E-Mobility ICT Interoperability Innovation Group (e-MI3) gave the following interpretation of interoperability in its report (2015): “interoperability is the ability to interoperate several different systems”.
The e-MI3 association further elaborated the definition and adapted it to different stakeholders:
- “For the e-mobility market, interoperability leads to non-discriminatory e-mobility services, such as charging and navigation, and provides access to services within a particular territory.”
- “From the customers’ point of view, interoperability is the ability to use the infrastructure for charging electric vehicles, regardless of where the e-vehicle is located, regardless of which e-vehicle customer is using and no matter who controls the charging point. In order to meet these customer requirements, the ecosystem must provide functions that can be divided into four groups:◦technical characteristics of charging stations (media for authentication, compliance of plug and socket …)
◦functions of e-charging station (labels, on how to use…)
◦system (system interconnection, data exchange …)
◦business and legal characteristics (roaming agreements between operators …).”
- “From the operator’s point of view, interoperability is the ability of an e-mobility provider to provide its customers with services (search and location, billing, booking, etc.) using the infrastructure of any operator under the umbrella of a B2B (business-to-business) at agreed prices.”
Computer software systems (back office) are required to exchange the information between the e-charging stations’ functions and monitoring of their operation and use. Benefits for the user: direct and indirect benefits that enable the user to have a properly functioning e-charging station on the right, accessible location, cheaper charging possibility for e-charging a vehicle at a certain time. There are other positive aspects, for example, in some cases, the user avoids the need for a contract with an individual service provider. Benefits for the operator: the ability to monitor variables (usage time, voltage, frequency of use, type of vehicle use …) that enable the proper localisation of the e-charging device. They are used for current or future price differentiation when charging services, setting up a telephone helpline, setting up a payment system (payment with cash, credit card payment, ID card, payment with a smartphone …), integration into the e-roaming platform.
However, operator interoperability management of more than 1 e-charging stations is not a requirement for roaming in e-roaming platforms. Owners of e-charging stations can skip the operator and connect directly to the e-roaming platform.
What is e-roaming?
Imagine roaming when using phone abroad, it is about the same by e-roaming platforms for e-charging stations. E-roaming platforms connect different market participants in order to create a digital, national and international network for charging electric vehicles – a single-service payment network with one contract or as little contracts for the user as it is possible. They can connect e-charging station operators, e-mobility service providers, energy suppliers, fleet managers, car sharing companies, service card providers, payment cards or car manufacturers. The contracting parties pay a fee to the owner and manager of the e-roaming platform.
The benefit for the user is that it can cgarge its e-vehicle at all charging stations that are included in the e-roaming platform by signing only one contract. The service user pays a service through the application of a centralised system managed by the owner of the e-roaming platform or pays to the service provider joined in the e-roaming platform.
E-roaming platform enables the user:
- locating (can quickly find the location of the e-charging station)
- reservation of the e-charging station
- to connect to the operator
- to obtain authorisation
- to pay (with a smartphone or identification card …)
Unified payment solutions and monitoring of battery charging of e-vehicles are possible.
Benefit from the business sector (operators, owners): the owner of the e-roaming platform reaches its profit with economies of scale, fees for e-roaming platform service. Those involved in the e-roaming platform use platform services: market their e-charging stations, simplify payment transactions and standardised cross-border billing costs.
In Slovenian at the moment (first half of 2018) there is not an Slovenian e-roaming platform enabling payments of e-charging services. Petrol is included in the Dutch e-roaming platform. At Petrols’ e-charging stations, placed at some OMVs’ and Petrols’ gas stations, the user pays the service of e-charging.
Most e-charging services are currently free of charge in Slovenia. There is a payment system at individual charging stations in a way that the user purchases a token that is thrown into an e-reel. At Petrol, the user must sign a contract with which he obtains an identification card and leases the charging packages. Learn more about payment terms and location of Petrol e-charging stations on
