Medium voltage
The grid level between the high-voltage network and the 400-volt street grid, in Germany 10 to 30 kV; fast-charging hubs connect here with their own transformer.

Why does the grid connection decide so much?From 250 kVA to 1.2 MW: why a fast-charging hub usually needs a medium-voltage connection with its own transformer, and what the grid operator's role is.Time. A new medium-voltage connection needs planning, a transformer and often cable works in the street. In this project, the offer gives about six months from signing to energisation (deep dive of this path).
