Hi,
... You could read electronics publications/magazines and automotive electronics publications online and get links to reference designs. All manufacturers (ST, TI, etc.) have an awful lot of information and designs you could copy or learn from before embarking on such a large and complex project. I'm afraid 'basic' and electric car chargers are incompatible concepts. As WFeldman stated, there are a lot of stipulations attached to most consumer/industrial design regarding laws and design safety on many levels.
My suggestion would be to hook up with a power engineer to deal with the hardware side I feel you may have some issues with (power is surprisingly complex - even old-fashioned transformer-based power supplies have to meet a plethora of standards) and perhaps not the time to do the endless reading, research and getting frustrated until one gets it right each circuit usually requires.
A preliminary block diagram of your idea would probably help to focus on which specific building blocks, reference designs and application notes, and datasheets, and standards you will need to swot up on and use. Best of luck.
