online eMPG converter

Here is a link to a web site that lets you easily convert between gasoline gallons and kilowatt hours of electricity.

If you just punch in how many kilowatt hours you used to charge your electric vehicle, it will tell you how much of a gallon of gasoline it equals.

Enter this number into the Ecomodder garage fuel log, along with how far you drove. (You reset the trip odometer every time, right?)

Then you can use the Ecomodder Garage Fuel Log the same way everyone else does, except you will realize how efficient electric vehicles are!

PS: Yes, the the garage fuel log DOES allow you to enter very small parts of a gallon of gas. My last charge was equal to .0202 gallons of gasoline, and the garage lets me enter that correctly!

FYI, simple conversion going on there:
1 gal(US) = 36.6 KWH

yeah, I figured that one out a while ago, but I am so bad/lazy at math, this is just that much easier.

I guess I was putting it out there in case the garage mpg gurus wanted to standardize the mpg results reported for the electric vehicles :rolleyes: (i.e. have a "enter the recharge kwh" field for electric vehicles)

HEY! That WOULD be a good idea.

Build in a kilowatt hour feature in that garage!

HINT HINT HINT...

Thanks for the link - much more convenient than remembering where I put the conversion numbers...

Since the 'gallons' were quite small anyway, I used one month worth of data for my last fill-up. For the past two months, I have been averaging about 252 watt-hours per mile (2.646 cents per mile) in the Citicar @ 10.5 cents per kWh.

It is actually cheaper than that (free after rebate from the local electric company) :thumbup:

Bookmarked, :thumbup: .

Question: Would this be a good conversion for using an engine block heater + Kill-A-Watt to pre-heat the engine block?

You just keep making it easier and easier to belive that I could build an EV, as well... :D
(I have a similar lack of skill/passion for math. I blame it on my third grade teacher...)

Good question. I don't think we have really had much of a conversation here in figuring out total energy use of gas AND electric when using an engine block heater to improve fuel economy.

I am guessing that you still come out WAY ahead in total energy use with the block heater.

Maybe we should start a new thread and figure out how much energy in total is used for block heater starts!?!?

 dcb 08-26-2008 11:51 AM

cfg83, that is an excellent idea.:thumbup: I can't think of any reason why you would use a different conversion factor for the block heater, it is a straight energy to energy conversion, from the wall vs from the pump.
