- My Leaf Charging Experience -



- First, the summary -
  • On a full charge, I can go about 60 miles on highway - ECO.
  • On a full charge, I can go about 90 miles at around 40mph - ECO.
  • On 110V, it takes about 5 hours to recharge my usual ~20 miles commute.


    - About consumption -


    Before the trip, state of charge shows 75% capacity.


    The trip was on 50% highway, ~38 miles.


    After the 38 mile trip, state of charge shows 25% capacity.
    That means that about 76 miles would have been with a full charge.
    (No, I did NOT use the climate control)
    Note, that the car and the web prediction agrees on range (31~32 miles), but not on charge time.

    In our case:
  • Original prediction was 75% to do 82 miles.
  • We got 50% to do 38 miles.
  • That means the original prediction should've said 57 miles.
  • That's 44% deviation!!! A LOT!!!
    (I can only assume, that this huge difference is because the original prediction was using
    my previous driving characteristics which was city driving and this was a highway drive.)

  • Current prediction : 1.24 mile/%



    - About charging -

    There is going to be a lot of graphs below to support this chart :


    This chart essentially shows, that charging is predictable and non-linear, which was expected.
    There were 3 charging sessions, thus the 3 "Range" and "mile/%" graphs.



    Now the supporting data :


    After charging the car for one hour :
  • Original estimate said 13, now it's 11.
  • That's charging twice as fast as predicted...
  • In the first hour, we charged 8%
  • Current prediction : 1.1 mile/%


    After charging the car an other hour ( 2 all together ) :
  • Original estimate 11, now 9:30.
  • We are now charging only 1.5x faster than estimated.
  • In the second hour, we charged 9%
  • Current prediction : 0.95 mile/%


    After charging the car an other hour ( 3 all together ) :
  • Original estimate 9:30, now 8:30.
  • We are now charging exactly as estimated.
  • In the third hour, we charged 8%
  • Current prediction : 0.88 mile/%

    *** Unfortunately I had to stop charging after this entry ***


    - A new charging session, after 10 miles city driving -

  • Current prediction : 0.98 mile/%




    After charging the car an other hour ( 4 all together ) :
  • Original estimate 7:00, now 6:30.
  • We are now charging 50% behind.
  • In the fourth hour, charging did not register.
  • Current prediction : 1.07 mile/%
    - 15 minutes after this entry, charge showed 67%, 63 miles, 6:00 charging time -




    After charging the car an other hour ( 5 all together ) :
  • Original estimate 6:30, now 5:00.
  • We are now charging 1.5x times faster.
  • In the fifth hour, we charged 8%
  • Current prediction : 1.00 mile/%
    - 15 minutes after this entry, charge showed 75%, 69 miles, 4:30 charging time -




    After charging the car an other hour ( 6 all together ) :
  • Original estimate 5:00, now 4:00.
  • We are now charging exactly as estimated.
  • In the sixth hour, we charged 8%
  • Current prediction : 0.96 mile/%



    After charging the car an other hour ( 7 all together ) :
  • Original estimate 4:00, now 3:00.
  • We are now charging exactly as estimated.
  • In the sixth hour, we charged 8%
  • Current prediction : 0.92 mile/%



    After charging the car an other half-hour ( 7.5 all together ) :
  • Original estimate 3:00, now 2:30.
  • We are now charging exactly as estimated.

    - A new charging session, after 6 miles city driving -


    We are starting from here :
  • Current prediction : 1.09 mile/%



    After charging the car one hour :
  • We are charging 1.5x faster than estimated.
  • In the first hour, we charged 8%
  • Current prediction : 1.07 mile/%



    After charging the car an other hour ( 2 all together ) :
  • Original estimate 2:30, now 2:00.
  • We are charging a bit behind of the estimated.
  • In the second hour, we charged 9%
  • Current prediction : 1.00 mile/%




    After charging the car an other hour ( 3 all together ) :
  • Original estimate 2:00, now 1:30.
  • We are charging slower than the estimated.
  • In the third hour, charging did not register.
  • Current prediction : 1.00 mile/%




    After charging the car an other hour ( 4 all together ) :
  • Original estimate 1:30, now 0:50.
