Thought Exercise: would an EV that is exclusively charged by solar qualify for the ITC?

Lol, so I was looking at the ITC language on the DOE (energy.gov) website...

The following expenses are included:
1. Solar PV panels or PV cells used to power an attic fan (but not the fan itself)
2. Contractor labor costs for onsite preparation, assembly, or original installation, including permitting fees, inspection costs, and developer fees
3. Balance-of-system equipment, including wiring, inverters, and mounting equipment
4. Energy storage devices that are charged exclusively by the associated solar PV panels, even if the storage is placed in service in a subsequent tax year to when the solar energy system is installed (however, the energy storage devices are still subject to the installation date requirements)
5. Sales taxes on eligible expenses

So if a homeowner sets up ChargeHQ or some fancy-pants API software to only allow an EV with on-site solar generation, would the "energy storage" portion of the EV qualify for the ITC? Maybe not the whole EV, but an estimated portion for the battery and inverter system?

I don't really see anything that says the battery has to be an installed fixture; only that the battery is charged by solar. And it doesn't actually say the use of the stored energy has to occur on site. It just says the stored energy has to come from solar.
