They do a lot with ChAdeMO, like DC all the way from the [new] solar panels to car's battery. I don't recall all the details, but where the standard has a range of voltages deemed acceptable, the equipment in the field doesn't accommodate the bottom of the range or something.
You have a greater need to know than I.
