Plug in all your numbers. Then take the watts (hp conversion) and divide by the mph in the same row.
for one hour at 65mph, 3821watts / 65miles = 60.78wh/mi
(on the conservative side i'd think it would be higher in the real world.)
But this also tells us that to make your car a serial hybrid with an infinite range on gasoline. You'd need at minimum a 3.82 kwh generator. Say 4.5-5kw generator to be safe and account for losses.
This gives you an idea of you would need. It would basically be plug and play for a 120volt battery pack. Like carrying an electrical outlet with you everywhere you go!
Honda EG5000 Portable Generator - EG5000C - 4500 Watt Portable Generator
$1,859
389cc
Weight: 177 Lbs. (80.29 kilograms)
Dimensions: 26.8L x 22.8W x 22.6H
(68.07 x 57.91 x 57.40 cm)
6 gallons fuel tank.
So $2,700 80 miles battery pack + $1,859 generator = $4,659 for your gas "tank."
It would get you the electric range of a Nissan Leaf, with the extended range of a Volt, at Prius mpg. |
I'm a little overwhelmed at all the numbers, but holy crap, batteries are expensive! The range extender isn't a thing I need to do, but it would be nice. For the money, probably not worth it vs. driving a normal ICE car for longer journeys. I'm a car guy; I have a few cars.
Is the $2700 battery pack... one single unit? Or could I order something a little larger to more easily accommodate my range requirement? Some research is in order.
Thanks again for all the help
