Hannover’s first ultra-fast charging station goes live – A Pilot Project with Enercity
Hanover-based energy service provider Enercity has put a total of ten charging points into operation on the premises of a restaurant, conveniently located near the A2 and B6 motorways, including four DC rapid charging stations with a charging capacity of up to 350 kW. Drivers can recharge their electric cars here in just a few minutes. There was previously no mains supply at the site, so Enercity turned to Ormazabal to implement the project.
“We greatly appreciate Ormazabal’s reliability, speed and flexibility, for example in the way the project’s special requirements were met. This specifically refers to the technical equipment for the substation, but also applies for design aspects that were important to our project partner Finca Bar Celona” Jan Trense, Services Division Manager at Enercity.
Compact concrete substation (2.4 x 2.6 m)
12 kV – 630 A – 20 kA
Scope of delivery:
compact prefabricated concrete transformer
substation – ga 2k1ts-Enercity MV system – 800 kVA transformer
specific for connection to DC chargers
LV Board with ACBs
A ga 2k1ts 630 A Ring Main Unit was installed in the substation for Medium Voltage distribution. The system’s very compact design also meant the building could be correspondingly small-scale, so the concrete substation measures just 2.4 x 2.6 metres. Low Voltage distribution board has also already been integrated in the unit. In addition, Ormazabal ensured that the switchgear and substation buildings have been tested in accordance with EN 62271-202.
Ormazabal developed a concept for the customer’s specific use and designed the building for the switching station. One special consideration was the transformer needed for this location, which had to be designed to handle the high charging capacity. In collaboration with the international Ormazabal business units, the Ormazabal sales department in Germany was able to offer a custom e-mobility transformer with 800 kVA that was individually tailored to the project.
