How to multiply amount of EV charging points

Here is business idea on how to multiply amount of EV chargers

Many homeowners are in position to provide EV charging points (power connection, parking places), even if they are not interested in EV vehicle at the moment. Some of them are willing to monetize the possibility, but don't want to deal with clearinghouse headaches and the necessary initial investment in expensive charger. Lack of the solution prevents many to share their existing EV charging point even with their next door neighbors.

So we need to invent:
  1. infrastructure that would incentivize (reimburse) home owners to expose their power to any EV consumer.
  2. Adapter device that is as cheap as possible, for every EV owner to buy.
How?

1. Create portable adapter that transforms home 3 phase power to NACS or CCS. Car driver will purchase and register the adapter with clearinghouse (see below) and carry it in the car.
 
 
2. Create DIY kit for homeowner to wire a standard 3 phase power socket (IEC 60309) in a rain-proof way on their parking place (or accessible from street) and stick "provider" RFID tag (received from clearinghouse). Should be doable by any certified electrician.

3. Create software infrastructure to charge consumers and reimburse homeowners, with secure producer-consumer authentication. The adapter will have a chip that reads RFID tag embedded into the power socket and calculate reimbursement amounts.

General notes:
  • It would be nice if the adapter  cooperates with the car's computer/SIM to communicate with the clearinghouse using cellular network
  • Homeowners should be able to set rates, down to zero to certain adapters (EV car owners), see who is connected at any given time and contact details of EV drivers.
  • Some amount expected to be taken by clearinghouse for infrastructure support
  • The adapter variations could be with embedded 3G SIM, charge indicator, anti theft device
