This video describes one directional EVSEs. Those are easy to install. I currently just plug my EVSE into a dryer outlet, but I will add a new connection for the F150 as my dryer outlet is limited to 30A.I thank this is a good video to understand that the so called charger is just an electrical connection. For the on board chargers in the truck.
A bi-directional EVSE that automatically switches between the house charging the car or the car powering the house is more complicated.
The easiest implementation would be to have a transfer switch that lets the car power the house during an outage.
Hopefully Ford or Sunrun will provide a way to automatically charge the car when electricity is cheap or when you have access solar power and automatically power the house when electricity is expensive or when the power is out. Hopefully there is also a way to control which circuits are powered depending on battery capacity. For example if the car battery has more than 75% capacity, power all circuits, between 50% and 75% power most circuits, below 50% power only critical circuits, and when there is only enough battery to drive to a DC fast charging, stop powering the house. The car should also be connected so that the solar panels will work during an outage. Most solar installations require some power to activate the inverter in the morning. Depending on your utility contract, you may be able to sell power from the battery back to the grid during peak. Maybe we can even sell capacity as spinning reserve or regulation energy some day.
