Medium voltage
The grid level of roughly 10 to 20 kV between the high-voltage network and the 400-volt street grid; large charging hubs usually 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. That makes it one of the longest steps of a project.
