How low will gas prices go

It takes about 7 kWh of electricity to fully charge the HVB at a cost of about $0.70 at 10 cents / kWh.  It would require 24/42 = 0.57 gallons of gas to go 24 miles (the range of the HVB).  The price of gas would have to drop below $0.70/0.57 = $1.23 / gallon for gas to be cheaper.

 

In my case, the electric cost is 6 cents / kWh and gas would have to drop to $0.74 / gallon.

The math....

 

So if you guys say you get 42mpg on gas, 24 miles / 42 = 0.57 gallons of gas to get that far.

 

Gas here is $2.35 a gallon.  So 0.57 x $2.35 = $1.34

 

This is saying $1.34 of gas to drive 24 miles.   If it takes 8kwh to fill up the Cmax, then the breakeven price would be $1.34 / 8 = 0.1675

 

Hate to say it but cost of electric here USED to be 0.1666 per kwh including all the fees and transmission costs.  0.10 per kwh plus about 6 cents and change for all the other fees.  Since November its gone up 37%.  My only saving grace is that I have solar panels, and also that gas usage causes more wear and tear on the engine parts and oil replacement so there is more cost then just the burning of the gas.

 

Interesting analogy...

It requires about 7 kWh to charge the HVB using a 240 V charger.  You can save 1 kWh using a 240 V charger vs. the 120 V charger.  My electric company offers EV discounts if you have a separately metered circuit for charging the car.  The program rates vary from $0.04 to $0.10 / kWh depending on the program and time of day.

So when its cold (not a huge problem here in the Pacific Northwest), I show 13 mile range with the heater on. I also am paying $.075 per KW, and I don't drain completely, so assuming a 7kWh charge.

 

13miles / 42mpg = 0.3095 gallons , Gas is 2.129 x .03095 gallons = $0.65897 cost to drive 13 miles on gas

@ $.075* 7kWh = $.525 to drive the same distance on electric.

 

So still cheaper to use electric, and like Raja said, less wear/tear on the car, but actually doing the math does show me not to be so worried about running the ICE when needed.

 

I guess I don't have the excuse to make my wife freeze in my car "NO we are not running the heater, we can't afford those luxuries!!!" ;-)

I figure at $2.00 I break even. I pay about $0.14/kwh, so it's about $1.00 to fill up the battery and I get about 20 miles out of it. 40 mpg on gas means about 1/2 gallon = 1 charge.

 

And gas is under $2.00/gal here now. :( I guess that's a good thing, and I'll keep charging the car at home, but it's no longer saving me money.

I charge the car because I like being a ninja and creeping around quietly.  I also like the electric drive for driving in town.  Also, f@#$ gas!  I hate getting out of my car in -10F to fuel up!   The "savings" really weren't in consideration. :flirt:   I'm just biding time until I get a Tesla and blow doors off people.
