There are horror stories about the cost of fueling electric cars and the "necessary" Grid upgrades.
Please use this, user friendly, bit of calculating, to clarify, just how little, eCar electricity should affect the Grid.
Let us try a little, simple math, might be a bit easier to understand.Electric cars
The Nisson Leaf and the 2012 Ford Focus are both rated at 100 mile range, with 24kWh and 23kWh batteries, respectively, and could be considered representative, based on quantity produced and manufacturers reputations. ecars compared
USA electric cost averages 11.53 cents per kWh.Electric cost, by StateThe math:
5,000 annual miles:
Divided by 100 miles per charge
Equals 50 charges of
Equals 1200 kWh
Multiplied by $.1153
Equals$138.36 annual car "fuel" cost
$2.66 per week, added to your electric bill!
1200kWh /24hours =50 days
You could run your electric car for a full year, (5000 miles), using the same amount of electricity as the small 1000kWh air conditioner uses, running ... less than, 1 day per week!!!
or ...You could run 7 eCars, each, 5000 miles annually, for the cost-electricity used by a 1 little 1000 watt air conditioner!10,000 annual miles:
Divided by 100 miles
Equals 100 charges of
Equals 2400 kWh
Multiplied by $.1153
Equals$276.72 annual car "fuel" cost
$23.06 monthly, added to your electric bill!
$5.32 per week.
A bit cheaper than $1,500 annual gasoline cost.
$125 monthly, dumped into your gas tank. ... if you average 25mpg ...
(Gas car ~25mpg)
( gasoline ~$3.75\gallon - when I passed the gas station tonight, well $3.759\gal. regular unleaded)
(10,000 miles/25mpg=400 gallons)
(400 gallons of gas x $3.75=$1500)
Don't despair, if you don't use an air conditioner, you probably use a small 1000 watt heater. Electrical usage compares, exactly the same. Even better?
The entire electric grid has reduced demand from about 1am till 6am. (varies)
They are forced to idle power generation plants burning fuel and maintaining workforce with no product sale.
In many areas, they offer greatly reduced pricing during these hours, some, 50%, or less!
Charging during these "off hours" might allow you to cut "fuel" cost, another 50%.
With no, none, zilch, 0%, increased drain on the grid!
