What is power management?
Power management is one of the most important functions of the charging station. An electric car takes a lot of energy, so the electrical input may be too low to ensure maximum charging speed. To avoid increasing power of the mains electricity and high costs related to it, the charging station can dynamically control the power output so that the power supply is fully utilized at the same time the internal grid remains protected from power failure.
What do I need to enable load management?
Load management can be divided into several categories:
• STATIC 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.
• DYNAMIC 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.
• HYBRID 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.

What kind of power input is needed?
The required power input is determined by the model of the electric vehicle and the built-in converter (on-board charger). Here you can check how your electric vehicle will charge.
Does the charging station need an Internet connection?
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.
How to charge an electric vehicle?
The electric vehicle must be physically connected to the charging station using a cable. Charging stations can be equipped with an already integrated charging cable or with a socket. After that, depending on the charging station, the charging starts automatically, or the charging needs to be activated with an RFID card or a mobile application. If the station does not have an authorization function, the charging process starts right away.
When to choose a DC charging station?
DC fast charging stations “bypass” the on-board charger and the electricity travels directly to the battery, so there is no “bottleneck” effect. DC charging station should be chosen when you want your electric car battery to charge in 20min to 3h. This type of charging stations are popular in places where it is necessary to charge an electric car very quickly, e.g. on highways, gas stations, roadside cafes / restaurants, short stops and elsewhere.
What kind of safety devices need to be integrated into the station?
One of the most important protections required in the installation of the charging station is a residual current protection device (RCD Type A). Its function is to protect people and equipment from electric shock. Depending on the charging station, this RCD must be type A or type B. Type A external leakage protection (price ~ 55eur) is sufficient when the station has an integrated 6mA DC leakage detection device. Type B external leakage protection (price ~ 320eur) is required if 6mA DC leakage protection is not integrated in the charging station. Another protection required in an electrical installation is a circuit breaker. Its purpose is to protect the power cable and other equipment from overload.
Can I install the charging station by myself?
You can also install the charging station mechanically (attach it to the wall) yourself, but in order to connect the station to the electrical mains, it must be done by a certified specialist in accordance with the rules provided by the Republic of Lithuania.
What warranty applies to works and equipment?
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. after the date of installation and for works 12 months. after installation.
How much does it cost to charge an electric car?
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 12 ct / kWh) will cost 1,8 Eur.
How long will it take for the charging station to pay off?
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.
How much will the electricity bill increase?
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.
What kind of maintenance procedure is required for charging stations?
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.
The DC fast charging station contains power electronic components. It is recommended to perform preventive maintenance for these stations according to the schedule provided by the manufacturer.
Which cars are suitable for charging stations?
Almost all electric vehicles support charging with AC and DC charging stations. Here you can check how your electric vehicle will charge. (aktyvi nuoroda)
How does the electric vehicle charge?
The charging process of an electric car can be compared to filling the fuel tank of a traditional car. Electric current, like fuel current – the higher it is, the faster the electric car battery will be recharged. If an electric car can charge from a three-phase inlet (imagine that the car is being fueled by three hoses) – the charging speed triples. It should be borne in mind that not all electric vehicles can accept three-phase AC charging. Here you can check the speed of your electric vehicle.
How long will it take to charge my electric car with an AC charging?
Electric car charging depends on several factors:
1. Electrical mains power kW
2. Maximum power of the installed charging station kW
3. Electric vehicle on-board charger power kW
4. Battery capacity kWh
5. Battery state of charge kWh
For example, the battery capacity of an electric car is 50 kWh and the state of charge is 10% (5 kWh). The electric car’s internal charger can take 11kW, and the station’s maximum power is 22kW. The electric car in this case will charge with 11kW power and 45 kWh of energy will be delivered in 45/11 = ~ 4h
How to disconnect the cable from the electric car when charging is complete?
At the end of the charging session, the Type 2 electric car charging socket usually unlocks when you press “Unlock” once or twice on the car’s remote control. In some cases 3 times. If this method did not work, look for the socket unlock button (function) inside EV on the control panel. If this method also did not work, there is an emergency unlocking of the socket in electric cars. Refer to the electric vehicle user manual instructions for this method.
Is it safe to charge an electric car with a portable charger (from a socket)?
The safest and most convenient way to charge an electric car is by using a charging station. We do not recommend using portable chargers every day as this is not a safe way to recharge your electric car battery. There is a risk that the household socket will not withstand the load and will be damaged. The socket may also not be protected against residual current leakage. If you have no other option to charge the electric vehicle, then change the maximum current to 10A (2.3 kW) in the electric vehicle settings or in the portable charger. Even safer – 6A (1.4kW) or 8A (1.85kW). This way the electric car will charge slowly but safely.
