Thinking about it a little more one option I believe is to have a regular plate and have an alternative fuel sticker. This may not be so common now, but a lot of the city owned vehicles were this way. One thing to consider is per Arizona law to legally use a charging station you must have an alternative fuel plate or sticker.
28-876. Parking spaces for electric vehicles; civil penalty
A. A person shall not stop, stand or park a motor vehicle within any parking space specially designated for parking and fueling motor vehicles fueled exclusively by electricity unless the motor vehicle is powered by electricity and has been issued an alternative fuel vehicle special plate or sticker pursuant to section 28-2416.
