Load management is one of the most important functions of the charging station. An electric car is electrically sensitive, so often the househol electrical mains input may be too low to fully meet the needs of the electric car. In order to avoid mains power increase of the household and high infrastructure costs,the charging station is able to control the power itself, so that the power supply is fully utilized at the same time the internal grid remains protected from “blowing the fuse”.


Load management can be divided into several categories:


In this way, we set the maximum possible power supplied for the station, which the station will not exceed in any case, thus protecting the internal network from voltage loss. No additional equipment is required for this Load management, everything is set in a smart mobile application.


This method is the most efficient to make the most of the available electrical power input and at the same time quickly charge the electric car. This will require an additional energy meter to act as a reference point for the charging station, according to which the station will adjust it’s power.


This load management method is especially convenient in larger parking lots. In this way, charging points can be categorized according to priority. In the event of a power shortage, electric cars connected to the first priority charging points will charge first while last ones will be recharged according to the lowest priority.

Note: not every charging station manufacturer offers methods described above

The required power input is determined by the model of the electric vehicle and the built-in converter.

POWER – the power of the station is selected according to the power of the building’s electrical mains input and the power of the EV’s built-in converter. It is most convenient to build the most powerful charging station, as the price difference is minor, but if you increase the electrical mains power in the future or change an EV that has a higher power built-in converter, you will not need to change the charging station to a more powerful one, just increase its capacity via mobile app.

INTEGRATED CABLE – is more convenient at home when it is attached to the station, because the user does not have to use his/her own cable. On the other hand, in public places, the charging stations might have integrated cable which can be damaged by a careless or irresponsible user. That can happen if the cable is dropped on the ground at the end of the charging process, where the connection or the cable itself may be damaged. This way, the station may require more maintenance.

RFID – this feature is required to authorize users. Typically, this functionality is required when a station is used in a public space to control access. Also in the presence of a fee-paying station and consumer accounting.

4G – this module is required when you need to transfer data to the owner’s or station manufacturer’s platform and perform electricity accounting, but there is no internet connection at the station installation site.

SHUTTER – is required in public areas when the electric vehicle driver has started the charging process and it is ensured that the EV will charge until the owner completes the process and other EV drivers will not be able to interrupt the charging process.

MID ENERGY METER AND DISPLAY – this built-in MID meter is required for commercial energy measurement. This meter has a higher accuracy class. A screen is required for the user to see how much energy was supplied into the battery and the cost of it.

ĮKROVIMO LAIKAS – Įkrovimo laikas priklauso nuo EV vidinio keitiklio, stotelės galingumo ir tinklo įvado galios. Preliminarūs įkrovimo laikai pateikti žemiau lentelėje vertinant, kad nurodytu galingumu įkraunama pati baterija.

Type1 or Type2?

The main difference is the type of connection and the number of phases. Type 1 connector transmits a single phase, Type 2 connector can transmit current through 3 phases, but that does not mean that the electric vehicle or charging station is utilizing 3 phases. The Type 2 connector provides an ability to transmit power through 3 phases, but both the station and the electric vehicle must also be able to charge in 3 phases. The Type 2 connector can be used for both 1-phase and 3-phase charging.

An Internet connection is required to monitor its operation remotely, as well as to control its operation and provide access to other users. Over the Internet, the data is transmitted to the manufacturer’s “cloud”, from where it is displayed on the platform. If the station owner does not need such services, the station also works without an Internet connection.

The electric vehicle must be physically connected to the charging station. After that, we activate the charging process with an RFID card or mobile app. If the station does not have an authorization function, the charging process starts when the electric vehicle is connected to the station immediately after the safety parameters are checked and automatic approval is granted for the safe start of the charging process.

The DC charging station bypasses the internal converter of the electric vehicle and the current flows directly to the battery, so there is no bottleneck effect. A DC charging station should be chosen when you want your electric car battery to charge in 20min to 3h.

The station should have built-in protection from overcurrent, voltage fluctuations, ground fault, surge and include PE (protective earth) continuity monitoring. Those embedded features protect both the user and the vehicle from injuries or damages.

You can install the charging station yourself, but in order to connect the station to the power supply, a certified specialist must complete the installation in accordance with the local legislation.

Please note the manufacturer’s warranty for the equipment and the contractor’s warranty for the installation works. Our warranty for the equipment is at least 24 months (depends on manufacturer) after the date of the purchase and for works 12 months after installation.

Electric vehicles, like cars with an internal combustion engine, have different fuel consumption, only the consumption of an electric car is calculated not in liters / 100 km, but in kilowatt-hours / 100 km. Typically, an EV consumes 12 to 25 kWh for 100 km distance, so when charging at home, you will get the price per 100 km multiplied by the amount of kWh consumed by the price per kWh you pay to the energy supplier. For example, charging an EV for a distance of 100 km with a consumption of 15 kWh / 100 km (estimating the price of 10 ct / kWh) will cost 1.5 Eur.

In this case, it depends on whether you have installed alternative energy sources and what kind of electricity supplier plan you have chosen. If you have a two-tariff plan and use the smart features of the AC charger which allows you to start charging when the price of electricity is lower, the station will break-even in 5-8 years.

Depends on how many kilometers you drive with an electric car. On average, 850 km per month, the price of electricity will increase by approximately 20-30 Eur per month.

The AC charging station requires very minimal maintenance as it does not have moving parts. Consumable parts, such as cable or plug may require more maintenance depending on the frequency of use and the aggressiveness of the environment.

Almost all electric vehicles support charging with AC and DC charging stations. For more information please refer to car manufacturers official webpage.

The charging process of an electric car can be compared to filling up the tank of a traditional car. Electric current, like a fuel flow – the higher current, the faster the battery will be recharged. If an electric vehicle can charge from a three-phase input, then imagine that three fuel guns are put in the car, so the refueling speed triples.
