Now, using this same approach, here's the analysis for Level 2 and Level 1 charging...
Level 1 (8A)
A charging rate of 0.9kW * 3.333miles/kWhr results in 3.0miles/rechargehour. To recharge the car after having driven 50 miles we get 50/3= 16.67hours. Thus, we can say that we get back to the charge we started with in 16.67+(50/60)= 17.5hours after starting off on our 50-mile trip (ugh!). Ok, so for 24 hours that gives us 24 * 50/17.5 = 68.6miles theoretical daily maximum using the Mitsubishi 120vac (level 1) EVSE.
How close to these theoretical maximums can you get?
There is a flaw to your thinking in the 8A example above. Your 68.6 mile daily maximum is only 6.6 miles above the estimated range before complete discharge. Even if you stick with driving 50 miles before recharging, are you stating that the most you can drive is only 18.6 miles more? You are looking for maximum range, and for that your scenario does not need to achieve maximum charge on the battery before starting the second leg. What if a driver starts with a full battery, commutes 40 miles to work and plugs the car in for 8 hours while at work, then drives home again? The car has gone 80 miles and only been subjected to 10 hours of driving + charging time. Even if you add 10 hours for charging the previous night, that is only 20 hours consumed.
