Take note that for a Nissan Leaf with the 6.6 kW unit you are suggested that you purchase the EXACT same charger as the Tesla Model S. Also note that Nissan claims "It takes about five hours to go from empty to a full charge with the 6.6 kW onboard charger" -- and their car is rated at 84-miles for a 24 kWh battery. (Remember my car has the smaller 3.3 kW unit, so it would charge significantly slower at the same EVSE supply)
In comparison, Tesla offers a 10 kW charging unit on-board in all cars (you can upgrade to a second but most users do not). Since Tesla offers "more" data than Nissan, I used the calculator here for various examples: http://www.teslamotors.com/charging#/calculator" onclick="window.open(this.href);return false;
My 2014 Tesla has a rated range of 265 miles. Using my wall connector (the SAME one that is the SAME cost for the Nissan), it would take 9-hours to fully charge my car from empty to full. Again this is a 240V 40A circuit, which can be VERY inexpensively installed in any home.
In comparison, if I only drove my Tesla for 85-miles (the rated range of a new Nissan Leaf, mine being 2012 is only rated for mid-70-miles)-- the Tesla would only take 3-hours to charge. This is 2-hours FASTER than the Nissan because again it has a 10 kW charger on-board, rather than a 6.6 kW (or in my case 3.3 kW) unit. Meaning, not only are you 100% wrong lorenfb, the truth is that the Tesla actually chargers FASTER with the same L2 charger.
Now let me look at two other scenarios here.
USER #1 - LIGHT DRIVING
This person NEVER drives their Leaf more than 75-miles per day (we won't even get into efficiency, and the fact that getting rated range is impossible in just about any EV at least here in Ohio in the cold of winter, etc). They have 10-hours at home every night. They buy/lease a Nissan Leaf, and charge at home each evening with 110-volts. I've personally never tried this but my understanding is that with a 6.6 kW charger you COULD completely recharge a Leaf in 10-hours at 6.6 kW. However, my 3.3 kW charger in my 2012 required FAR more than 10-hours to fully recharge. Plus on many days I drive more than 75-miles (or in winter, I only get 40-45 miles per charge due to weather) (so I am personally NOT User #1)
USER #2 - MODERATE TO HIGH DRIVING
This is what I believe MOST people need. If not daily, at least evenings & weekends. Especially in the Midwest, where a drive to work suck as mine (25-miles) uses up 60-70% rated range in the winter time (Today we yielded only 3.75 miles per bar, and around 2.9 miles per kWh on the dash). Based on this we charged the Leaf to 80%, and when we got home it had 12-miles range remaining, 2-bars on the dash, and we had driven 31-miles. We would have been able to yield at most 45 miles-- driving in ECO mode, heat set to 68-deg F interior cabin, exterior temps 20-40 degrees today. People in this situation will REQUIRE charing almost all the time they are at home, and L2 charging is FAR superior.
BUT THE BOTTOM LINE IS THIS....
(1) if you buy ANY EV, and drive in excess of 50-miles per day, you'll need L2 EVSE charging at home (or frequent visits to L2 EVSE locations) to maintain the range on a Nissan Leaf
(2) the cost to purchase EVSE for a Tesla vs Nissan Leaf is nearly identical, or in my case, 100% the same because we bought one EVSE that works for both cars ... you should be able to get an L2 EVSE installed at most residences across the USA for under $1,000 total materials & labor
(3) pricing to charge these two cars is nearly identical, and the effective cost-per-mile is also VERY similar... though driving style and such will matter. However, our finding thus far is that the price for the Nissan Leaf has been around $0.042 per mile, compared to the Tesla at $0.046 per mile (this is cost I pay per kWh against the efficiency listed on vehicle dash only).
(4) all potential buyers of an EVSE should make sure to look at their range needs, mileage, ability to add an EVSE (L2) to their residence, or access to such stations in the wild where possible. I'd suspect in many larger cities public L2 stations would negate the need for such at home, and obviously as mentioned here a condo or similar situation might make L2 install impossible... but again, if you drive enough mileage you'll need that, regardless of which car you get... because they both require L2 for most users ( > 50 miles per day) ... those users who drive "few" miles would have equally as easy time using 110v to charge EITHER car....
