Škoda Enyaq iV

The new Škoda Enyaq iV – a milestone in the transition to electromobility in the Czech market?

The focus of the largest domestic manufacturer Škoda Auto on launching new electrically powered models undoubtedly plays a key role in the further development of electromobility in Europe, but especially in the Czech Republic and Slovakia. In September of this year, we registered one of the carmaker’s most important steps on its path to transformation towards the production of electric models. Quite possibly, one of the most important models in the entire history of Škoda was introduced. The Enyaq iV is the first Škoda car designed from the ground up to as a fully electric car.

Although neither Škoda Enyaq iVthe longest nor the fastest, it will be the Škoda with the highest base price. The new Enyaq iV will become the flagship of the Czech carmaker and also wants to be the model bringing new automotive trends.
Despite being shorter than the new Octavia (a lower-middle-class model), the Enyaq looks like a premium value car on the outside, whose presence on the road is emphasized by a backlit front radiator grille.
The group’s chassis base for electric cars, ID.3 , first launched by Volkswagen this autumn, is essentially reminiscent of a skateboard. There are batteries located in the floor between the axes, the driving power is provided by an electric motor, which is only at the rear of the basic versions of Enyaq, and therefore drives the rear wheels. In case of higher class versions also at the front which makes them logically all-wheel drives.
In addition to various configurations of electric motors, this concept allows you to play with a variety of battery capacities. The basic version has a capacity of about 50 kWh, it will be available, however, only in foreign markets. In the Czech Republic, only the larger “sixty” will be available with a usable capacity of 58 kWŠkoda Enyaq iVh and a range of 390 km. The one electric motor will be located in the rear, and its power is 132 kW.
The true variability of the MEB platform is shown by the Enyaq 80 version. It has a usable capacity of 77 kWh and in the basic version with a 150 kW electric motor at the rear, it will travel up to 510 km on a single charge.
The basic version can perform fast charging with an output of 50 kW, but the top variants can handle 125 kW, which  means that from 5 to 80 percent of the capacity, you will charge in just 38 minutes. Other important parameter is the power of the on-board charger, which is a solid 11 kW. That means that when hooked up to a sufficiently strong wallbox you will be able to charge from zero to full in six or eight hours, depending on the version.
Enyaq therefore seems to be versatile enough for practical life. Thanks to the large batteries, it will have a sufficiently long driving range and recharging should be fast enough to make even longer journeys possible. Consumption will be reduced by a heat pump, which will heat the cabin with waste heat from the battery in winter.
The interior is unusually high grade for Škoda, but all the more pleasantly luxurious. The materials work very well, the dashboard is sewn with leather. The car’s control center is a 13-inch display in the middle of the instrument panel, whose design looks the same as the new Octavia, but has specific features related to emobility. Almost everything is controlled through the display, including air conditioning, driving modes and so on, but at least six small buttons remain under the central ventilation vents for quick selection.
The ŠkŠkoda Enyaq iVoda Enyaq iV will be offered in a wide range of versions and performance alternatives. As already mentioned, the basic version of the iV 50 with an output of 109 kW and a 55 kWh battery will not be sold in the Czech Republic, in our country the entry model is based on a 62 kWh battery with an output of 132 kW. If you need more power and capacity, you can choose the iV 80 version with an output of 150 kW and a battery with a capacity of 82 kWh (usable 77 kWh).
With the Enyaq iV model, Škoda returns to the rear-wheel drive in the case of single-engine versions. However, there will also be an 80X ATV with two electric motors and a combined power of 225 kW (75 kW at the front, 150 kW at the rear). Only with all-wheel drive will there be an RS iV version, which will offer 80X power but more dynamic characteristics. That’s why the Škoda RS version gives an acceleration from zero to 100 in 6.2 seconds, while the 80X will achieve the same speed in seven seconds.
While the market will probably see in the new Enyaq – thanks to an already decent range and a reasonably short fast charging time – an equivalent alternative to powerful SUVs with diesel engines, we, i.e. experts and companies working to create conditions for smooth transition to electromobility believe that the brand new model of the key Czech carmaker will become a significant first milestone on the road to an emission-free traffic on our roads and highways.


„Unusable“ soil as a basis for photovoltaic power plants

Already in the September edition, we mentioned the construction of a photovoltaic power plant at a landfill in the north of the Netherlands (project Bovenveld). This construction has been successfully completed, handed over to the client and the land, which was difficult to use for other purposes, has now a capacity of 7 MWp of Solar power and will supply electricity to the surrounding buildings.

The use of landfills is considerably limited due to the possibility of gas formation, the content of heavy metals and hazardous compounds, the uncertain stability of the subsoil at higher loads and more. The photovoltaic power plant therefore seems to be an ideal economic use. However, it is not just about economic potential. It is an effort to underline and multiply the positive environmental impacts of solar power plants in terms of clean energy by increasing the efficiency of solar panels with new materials and technologies, increase the recyclability of panels, but choosing a photovoltaic power plant location can create a very smart environmental solution. Advantages of constructing the PV plants on recultivated landfill is partially compensated by the need for high level of experience in the construction of these systems and compliance with stricter legislative requirements so as to prevent leakage of contaminated water or soil from the subsoil. The first legislative requirement implemented in this project was a layer of steel slag, which strengthens the surface and separates the landfill environment. A special safety feature that relates to the possible leakage of gases from the landfill body was the use of electrical work machines to prevent the possibility of explosion.
In the previous construction, 2 types of under-constructions were used due to the irregular terrain. In the current project, located in the Netherlands near the town of Eerbeek, only Sunbeam structures were used, which require a flat base, as their original use is for flat roofs.
We are delivering since mid-September also other interesting landfill project of a similar size to be connected end of this year for a customer and at a location which we are not allowed to disclose.  The energy obtained at the landfill will supply 1,600 local households. Good planning in the implementation of the project ensured not only the ecological and economic benefits of using the old landfill, its sufficient security, but also, for example, the incorporation of an infiltration pond for rainwater until the created subsoil becomes impermeable. The aesthetic aspect of the project was also considered, when due to the terrain and the planting of slopes with plants, the power plant will hardly be visible.
Interest in the use of old landfills for the production of energy from renewable sources is becoming increasingly popular and it is not only about solar energy, but often about combinations with the use of biogas, which are generated in the landfill by decomposition of waste (see picture below). Progressive markets in this direction are countries that have been using renewables and green energy for a long time and where a well-thought-out infrastructure is being created, where brownfields, landfills and large roof areas are mainly used for the construction of solar power plants, for example. As our company is headquartered in Prague we believe that in the Czech Republic these projects will be also more implemented in the near future and we will be able to utilise our experience from abroad to improve ecological progress in our country in the field of solar energy production.
