People keep asking me how much it costs to drive (recharge) the ForkenSwift. So without further ado...
After 20+ km of driving, the pack takes about 24 hours to recharge, using the slow, "semi-smart" (voltage sensing, auto shut-off) 24vdc/10A charger. That's splitting the pack, 12 hours on the back 4 batts, then 12 hrs on the front 4.
Yes, 10A is that slow.
3.6 amps (24v charger) at 120 volts AC =
432 watts total
24 hours per charge for 25 km
10368 watt hours per charge
@ 6 cents per kwh (standard Ontario energy mix rate - Ivan's house)
0.62208 $ per charge
25 km/charge
0.024883 $ per km
2.5 cents/km
@ 9 cents per kwh (100% renewable energy rate - my house)
0.93312 $ per charge
25 km/charge
0.037325 $ per km
3.7 cents/km
Compare to gasoline cost for the Blackfly @ 75 mpg (US) & $1 / L ...
3.14 L/100 km (3.14 = 75 mpg (US))
0.0314 L/km
1 $/L
0.0314 $/km
3.1 cents/km
