I think what you're looking for is the Lightyear One. https://lightyear.one/
A modern, amazingly efficient EV, with solar roof. But since it's so niche,
as described before, it will cost you around $170k :)
Maybe more... or maybe less. It all depends on how many they can sell.
As for the original question of "faking out EV to accept solar input while
driving" the easiest way of doing this is just connecting some wires
directly to the HV battery +/-, with contactors (positive and negative),
fuses (positive and negative), and your 400VDC CC-CV MPPT solar charge
controller (likely custom required) with reverse current blocking, to your
custom roof mounted solar panel.
I don't think this would be easy; nor would it be safe. Too much risk of
a shock hazard, since you'd have the pack's high voltage on the exterior
panels.
I think an easier and safer approach would be to use low-voltage PV
cells or panels to charge the 12v battery with an MPPT controller. It
will get the most out of the panels, and also avoid overcharging the
battery. These are common, commercially available products.
Then, use an isolated 12vdc inverter to step this up to charge the HVDC
pack. This could be as simple as a standard 120vac inverter, with a
voltage doubler or tripler on its output to convert it to DC and step it
up to charge the pack. With the right choice of components, its voltage
can be chosen to make it impossible to overcharge the pack.
Still, it's a niche solution. It would be better to leave the PV panels
at home, if you live in a place where that's possible.
