If you charge for 20 hours on Level 1, pulling 1.44kW (120V x 12amps) from the wall, your total would be 28.8kWh x 0.32 = $9.22. (Close to the $10 you are assuming.)ELROY wrote:So all in all, if it takes 20hrs to charge (23 indicated), it will be about $10 in electricity to have traveled 66miles. At $4.20 gallon for fuel, this would be about 2.38 gallons of fuel, or about the same costs as a gas car achieving 27.73mpg. Not remarkable at all.
Once I get a metered level II charger at .13 cents /kwhr instead of my current .32 cents kwhr, then is will only be about $3.90 to charge the battery instead of $10. The resulting economy would be equivalent to a 71mpg trip, which I could live with.
However, with a new battery's usable 21kWh, and assuming 86% efficiency on L2, it would cost you $3.17 to fill-up, ( (21 / .86) * 0.13 ), rather than $3.90.
The largest variable, however, is your assumed 66 miles from full-to-empty. You should be able to at least match the 73 miles EPA rating or better. But even given the conservative 73 miles (which would be 3.48miles/kWh) ... I get:
$3.17 spent, or ($3.17 / $4.20) = 0.755 gallons for 73 miles ==> 97mpg ! Not bad. (The car is rated at 99MPGe.)
Something is wrong. Check your tire pressures (try cold psi at 40). Also make sure HVAC is completely off (the heater "steals" a lot of energy).ELROY wrote:Trying to get 5mi/kwhr would be very difficult. With the cruise control set at 35mph-45mph, it was usually below 5.
