We have completed another exceptional project. This time it is unique mainly because of its power and size. Successfully passed the tests of a charging station with a power of 1.2 MW! This giant can charge up to 16 electric buses at the same time! This is the largest station produced in the history of the company.

Megastation for Hamburg

This charging station was built for one of the largest public transport operators in Germany, Verkehrsbetriebe Hamburg-Holstein. This is the first of two blocks to be delivered to Hamburg in 2019.

Mega-casing made of concrete

Not only is the power of this charger unique, but also its casing. The power of 1.2 MW was enclosed in a concrete container, which was specially ordered and weighs almost 25,000 kg. And when the heart of the charging station is topped up with cables, contactors and power modules, it weighs almost 30,000 kg. The transport of this weight will therefore be a major logistical challenge, and powerful cranes will be required to unload it.

Mega-power – 1.2 MW

The 1.2 MW unit is divided into 4 modules with a capacity of 300 kW. To each of them are connected 2 satellites, each of which has two charging outputs. This means that the power of 300 kW can be distributed between 4 charging points and can power 4 buses at the same time.

Intelligent power management system

The infrastructure has an intelligent management system that allows you to make the most of its power. If two electric buses are connected to the station, 150 kW is transferred from the 300 kW module to each of them. When three vehicles are charged, two of them are powered by 75 kW and one by 150 kW. If 4 electric buses are connected at the same time, each bus receives 75 kW each.



PKM Katowice, one of the largest public transport operators in Upper Silesia, consistently implements the plan to transform the city’ fleet. At the beginning of February the first electric bus was launched in Katowice, now the city fast charging station from Ekoenergetyka-Polska has been put into operation.

Fast charging station in the city centre

The first electric bus that left for the streets of Katowice operates in the crowded city center. Therefore, it was necessary to install a fast charging station, which recharges the battery of the bus at a stop.

The station launched by the Polish manufacturer of electric vehicle charging infrastructure has a capacity of 200 kW with the possibility of increasing the power to 400 kW. Buses are charged by an inverted pantograph, which allows to reduce the weight of the bus and increase the reliability of the whole system, due to the lack of moving parts on the vehicle.

It is one of the first in Poland, and another after Inowrocław, the implementation of OppCharge type solution by Ekoenergetyka-Polska. Thanks to it, the charging process itself is fully automated and does not require driver’s intervention. The bus communicates with the charging station automatically via a wireless wi-fi network.

Charging in 5 minutes

The reversed pantograph charging system allows to recharge the bus battery in a very short time. The installed 200 kW station is able to charge 50% of the bus battery (capacity 120 kWh) in about 18 minutes, and in case of increasing the charging station power to 400 kW in 9 minutes.
