OK. I just got the results of my first metered re-charge and although it was only from 63% - 99% at least its more data.

Our elect cost? I used the secondary tariff since we would use the first 160kWh of expensive electricity even if we didnt have Twizy so our secondary unit cost is 10.354p/kWh (Scottish Power. Heavily negotiated)

Distance covered = 13.3 miles

Temperature = 10 Deg C

Battery remaining = 63%

Theoretical Range = 36.9 miles (no attempt to drive gently then)

Total Power to charge to 99% = 2.3 kWh

Price to charge @ 10.354p/kWh = 23.81 p

Effective cost per mile = 1.79p/mile

Effective Cost for full recharge = 66.15p

Charge Details

Time Zero (start)

Battery 63%

Power = 9.27 amps / 2.209 - 2.216 kW modulated charge

Time = 38 mins

Battery = 83%

Power = 2.190 - 2.200 kW

Time 65 mins

Battery = 96%

Power = 3.65 amps

Time 85 mins

Battery = 99%

Power = 1.55 amps

If you add the battery lease to that of 6000 miles p.a. and £40/month (VAT reclaimed) : 8p/mile

Twizy cost me 9.79 p/mile

Petrol equivalent (@ 1.42p/litre or 4.5461 ltres/gal = £6.4555 / gall

Equals 65.94 mile per gallon

So the direct running costs do not represent a fantastic saving over a frugal small car BUT

I am not emitting as much noise

I am not stinking out the highway as much

I am not damaging the highway as much

AND I AM MAKING PEOPLE SMILE

AND I CAN PARK ALMOST ANYWHERE

AND I FEEL GOOD FOR DOING ALL THIS
