April 30, 2020: The largest EV charging park in Europe, the ‘Seed & Greet’ park in Germany, will be powered by battery storage systems from German battery maker Tesvolt, the company said on April 22.
The charging park, at the Kreuz Hilden junction connecting the A3 and A46 motorways in North Rhine-Westphalia, covers 12,000 square metres and will have 114 charging points, 62 of them fast charging stations from Tesla and Fastned.
However, if the current 235,000 vehicles passing through the junction on average each day were all electric and all needed charging, each charging point would have to deal with more than 2,000 cars a day.
The 2MWh battery capacity will be filled from rooftop panels and two small wind power installations at the site, as well as energy from the grid when it is cheap.
At peak times, the batteries will be discharged to avoid drawing from the grid, said Gregor Hinz, energy consultant and general technical planner for the project, who believes the storage systems will pay for themselves within two years.
“It is particularly important that a charging park’s storage systems can be quickly charged and discharged at any time,” said Hinz. “Currently, only a few storage products are capable of this.”
In what could become a model for future mass charging stations, the park will also offer places to eat and walk around as drivers wait for their cars to charge.
Tesvolt says it has more than 1,200 energy storage projects in place around the world.
