Not to dispute your claim that it's low, but the physics checks out.
The cited link saves me explaining it:
>Reports are 300 W/mile at 55 mph. If you do the product of these two numbers (300 * 55) all units but W will cancell eachother out so the answer is 16500 W = 16.5kW
The time component being on the mph allows the conversion.
- sokoloff 9y agoNo. 300 Watts / mile * 55 mile / hour leaves you with 16500 Watts / hour, which is a non-sensical unit. On the other hand, using the correct units (300Wh/mile): 300 Watt * hour / mile * 55 mile / hour = 16500 Watts [a sensible unit] (or about 22 horsepower which is reasonable for a steady 55mph cruise). Do that for an hour, and you get 16.5kWh of energy consumption and cover 55 miles, for an energy efficiency of 3.33 miles/kWh, which is in the ballpark (albeit low) for what my LEAF delivers (averaging a bit over 4 miles/kWh at average speeds somewhat lower than 55 mph)
- averagewall 9y agoThat's not obvious. Why @ means *? And what does W/mile mean?
