Reading the "Return of the Electrathon" article in the excellent Plugged In magazine, I was interested in the range of energy consumption figures for the various vehicles that did the lap circuits. Thought it might be useful if we could record our Wh/mile figures in one place. It would obviously help with comparison if we could give some information about the driving conditions, average speed, weight of vehicle and whether power is measured at the charger socket or onboard the vehicle. Anyone interested?
I don't have a power socket watt meter yet, so can anyone give me an idea of the average charging efficiency?
Energy consumption figures
Good idea Malcolm, can only really tell you that my Berlingo returns about 20kwh recharge for around 60miles of range.
That relatively flat terrain with average speed of I'd say 40mph-45mph I'd recon, but to be honest I've never REALLY taken any real hardcore measurements

I reject reality and substitute my own !!!!!!

Aldi were recently selling them for £6.99 I forgot to show Chris the one I bought When I was at Goodwood the other week Sorry Chris

Yeah, sorry about that I specifically made sure I put it in the car to show you too. I did consider buying a few too as I'm sure some of the other members of the Society would like to have one or more.
If you're lucky you may find some still at your local Aldi as they do tend to loiter a while if they are not immediately obvious to people what you use them for
Started this and then sort of forgot about it. Still think it would be useful to record Wh/mile figures here. Even if we can't quote figures at a fixed speed or under directly comparable conditions, they could be useful for giving an idea of real-life battery requirements.
Etek-powered motorbike:
Weight including me: 200 kg
Conditions: Running around town, average speed low 20s, top speed 50 mph.
Measured: onboard
Energy consumption: 80 Wh/mile

With the 1989 Ford Fiesta which ChrisB kindly sold me, the average energy figures for 20,000 miles are as follows. With 30 of TS 200 Ah cells and a pair of Lynch motors, the car with my wife and myself in it weights about a ton. Most driving is in hilly country, with a lot of 10% gradient hills. At age 83 I do not drive fast.
average 208 driving watt-hour per mile
average Zivan recharge energy 221 watt-hour per mile
Driving up these 10% hills every day, figures are
normally gear 3 at maximum: 135 amps, 102 volts, 25 degC, 34 mph
occasionally gear 4 (not maxm) 200 amps 97 volts, 39 mph.
Thank you Chris for a wonderful car conversion which has given us enormous pleasure. The range is down to about 80 miles because 3 cells are now feeling their age (like us!) Alan & Honor Ward
