More proof that zrick is a dumbass.
Bmw i3 42kwh battery, 12 gallons produces 350kwh. 12% of that energy (stored in batteries on the unit) or 1.44 gallons of diesel for 153 miles i3 range.
That 106 miles per gallon.
Well he does keep randomly quoting everything on the web as "gospel" without double checking...& most of those people he quotes know bugger all about what they are saying. Its mainly he who shouts loudest wins....!!.
I couldn't find an exact diesel generator to the one used, but here's a Perkins spec sheet, which gives fuel consumption of 42lt/hr for a 50% load (180kW continuous load).
If that BMW has a 42kW battery & the charger attached to the generator is a "Fast" type then in theory at 180kW/hr a 42kW battery will be charged in 13.85minutes. If fuel consumption of the generator is 42lts at half load of 180kW/hr, then for 13.85minutes fuel consumption is 9.69lts or 2.56US gallons, to charge the 42kW battery.
If the range of the BMW is 153miles then that's 59.76MPG (US)
