Hey! I need some help guesstimating my watts/hour/mile for an electric truck on the drawing board.

I am looking at the following setup:

• 2008 Silverado 1500 at around 4600lbs
• Kostov 13" Motor @ 250VDC
• WarpDrive 360VDC/1400amp Controller
• 34kw/340volt Lithium Pack

According to my math, it looks like it will use 480 per mile @ 65mph. Based on 28ft frontal area, .45 drag coefficient. However. I was looking around EVAlbum and saw a few other vehicles, one being a large full size truck using around 1040wattshour/mile, and an F150 claiming to use about 350.

I know the larger truck on EVAlbum had lead acid batteries weighing it down and a high Perkuet number to deal with. Also most people seem to measure amount of power per mile from the charger, for this I am more concerned with calculating range, not my electric bill.

What do you guys think? (Let's assume I drive rationally, also - no racing haha)

I heard that 8000W is approximately equal to a gal of gas. If your truck was rated for 20 miles per gal then about 8000W should get you about 20 miles. It worked out well for my conversion.

That would be a dream. Can anyone else comment on this? That is on par with what I've seen on some people's EVAlbum posts, but certainly not others...

Also, Yabert... can you send that calcuator to me?
