Common? There's a loaded question!
Complex features? Does that mean you need four wires (two hots, a neutral, and a ground?)
There are two answers- the 'legal' and the 'useful.'
First, the legal answer... Ordinarily, your charger would be submitted to someone like UL for evaluation and testing. As part of their examination, it would be decided exactly what plug and over-current protection your charger should have.
There's been a lot of work in this area recently, as truck stops are being required to install 'power stations' for each parked truck. Also, with more electric vehicles being proposed, this area has been quite active. Some plug patterns might be set aside or standardized for this use.
As for the "useful" answer, nearly every home has a 30-A/230V receptacle for the clothes dryer. Using such a circuit might even be legal, considering what overcurrent protection might be part of the charging station.
Air conditioning units typically have power somewhere around 25A/230V. Unfortunately, such units are also hard-wired to a disconnect. That disconnect might be a convenient place to add a receptacle, though.
