The Sun: Electric dreams

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

I was given a sneak preview of pictures of the car and it looks a bit like an Aston Martin and with prices expected to start at around £32,250 at today’s exchange rates.

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.

16 hours to recharge with a standard plug?????????????

That is what happens when you go from 70A to 15A :frown:

 

[TedK]

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

 

[Joseph]

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.

Isn't UK standard 220V?

 

[TEG]

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.
