    Electric dreams | The Sun |Motors|Ken Gibson

    This is good, because if you don't know The Sun, it's the archetypal tabloid with a blue collar audience. General elections have been won and lost by the power of the Sun's editorial and Ken Gibson is an old school motoring journalist known to tell it like it is. Therefore singing the praise of an EV in this type of column is a milestone.

    And

    So - pretty good news :smile:

    Hmm...32,250 is oddly precise.

    Just the conversion of $60,000 which is often said as the target price for Model S.

    I thought the charge time doubled to 7 hours when you went with a standard plug (110V)

    A standard plug (15 amps and ~110/120 volts, idk) will put out ~1.7 kwh in one hour. The Tesla has a 53kwh battery pack so including losses of battery charging, it would take a long time, over thirty hours.

    70amp*220v=15.4kW circuit (Tesla special home charger)
    30amp*220v=6.6kW circuit (UK plug)
    12amp*110v=1.3kW circuit (typical USA household plug)

    Battery pack capacity = ~54kWh
    54kWh/15.4kW= ~ 3.5 hours (home charger)
    54kWh/6.6kW= approx 8 hours from the UK plug
    54kWh/1.3kW= approx 41 hours from the USA plug

    You really want a 220v circuit (welder/dryer/range) for overnight charging.
    Typical USA household plugs will take way too long.

    30 Amps/220 Volts is the standard electric cooker circuit here in the UK, but 45 Amps is also widespread, which knocks the time down to under six hours for a complete empty to full recharge.

    Got it, so a 30A dryer circuit would charge it up in one night.
