SAE Combo Plug And Receptacle
Here is video presenting a Combined Charging System for AC & DC charging in Europe (the US variant - SAE Combo is different). Such a system is already utilized by BMW and Volkswagen.
The idea behind this solution is simple - one inlet in car, enabling AC and DC charging up to 100 kW (well, AC charging up to 43 kW).
Depending on the charging point, you just need to insert the AC plug or larger DC plug using additional DC pins on the bottom.
The SAE version doesn't have 3-phase capability because it inherits the J1772 single phase plug, while in Europe the base was 3-phase plug.
