OK, thanks.
I want to go a bit more into details. Specifically, I know that in case of a DC fast charging, a DC current is supplied to the electric vehicle by a proper plug. Outer connection of a charging station might be a Chademo, GB/T or a Tesla connector, but before that stage, a DC filter stage must be present. I know some filter producers developed filters for EV chargers and they have busbar connections. My question now is how these filters are connected to outer connectors.
