But w/ no other figures it wont tell me how much its costing me.
As much as I'd love to see them pervade, I have a bad feeling about the whole electric scheme in general. Nothing's stopping utility companies from manipulating energy costs (through speculation for e.g.) and raping big time like the oily guys are doing today. All thats required is a simple rewrite of the rules, and we all know that governments will be too happy to oblige.
As long as the current model remains, meaningful change will be far off.
Actually it wouldn't since charge In this case is a very vague form of measurement. How do you determine mileage on half a charge.
Maybe they could use like minutes of operation. Like a fully charged car would allow you to run for 3 hours but then you'd have to factor in speed because that could alter the time you could operate the vehicle. I guess a trip computer could remedy that.
Miles Per Charge (MPC) would not be a sufficient measurement because all electric cars have different battery packs. One may use the electricity more efficiently but have a lower MPC rating because the car you're comparing it to has a 3X bigger battery pack. It says nothing for efficiency. MPG is accurate because it measures the actual fuel burned for this car (at the fuel company, when they convert oil to electricity).
Fine, then do Miles Per Charge divided by the charge in the battery. There, done, it's normalized.
I can get 50 miles per charge / 5 charge units = 10 miles per charge unit Or I can get 100 miles per charge, but for 10 charge units = 10 miles per charge unit.
So consumers would need to know 2 of 3 numbers, the range on a single charge, size of battery, and/or miles per charge unit. You can estimate the cost of electricity in your area to figure out how much it costs to "fill" the tank.
It's the same as knowing MPG, the number of gallons in your tank, thus giving you the range. Again, knowing any 2 can get you the 3rd. You can also calculate the cost of filling up from those numbers.
Now that we've thrown 'em off the trail, use the form below to get in touch with the people at Engadget. Please fill in all of the required fields because they're required.
It seems a simple MPC (miles per charge) rating would suffice.

That wouldn't be a measure of it's efficiency though. That would be a measure of it's battery capacity.
