First, we joined PlugShare where we have access to chargers across the country. There is a gadget Tom bought that helps us considerably and if you are a Tesla owner I would recommend you purchase one and keep it in your car (this is where the sub-trunk comes in handy). It's called a CHAdeMO (link goes to Tesla Motors site). I was curious about just what that was or even meant and I found this lovely little explanation: CHAdeMO is an abbreviation of "CHArge de MOve", equivalent to "move using charge" or "move by charge". The name is also a pun drawn from O cha demo ikaga desuka in Japanese, translating to English as "How about some tea?", referring to the time it would take to charge a car. CHAdeMO can charge low-range (120 km / 75miles) electric cars in less than half an hour. We have used ours many, many times at Nissan dealers, who are, so far, a delightfully accommodating bunch.
Our current go to Nissan dealers in Alabama are Jack Ingram Nissan in Montgomery and Benton Nissan just south of Birmingham in Hoover. Rumor has it we are getting a Supercharger in Birmingham, but until we do ... we go CHAdeMo all the way!
If you've never seen a Tesla Supercharger they are often located off most US interstates, malls, airports, and sometimes one needs to take the scenic route to find one! Here we are at the Auburn Supercharger.
