how much energy does an electric car use per hour?
25804
If electricity costs $0.11 per kWh and the vehicle consumes 34 kWh to travel 100 miles, the cost per mile is about $0.04. If electricity costs $0.11 per kilowatt-hour, charging an EV with a 70-mile range (assuming a fully depleted 24 kWh battery) will cost about $2.64 to reach a full charge.

This tells you that the fuel for an electric vehicle with an energy efficiency of 3 miles per kWh costs about 3.3 cents per mile when electricity costs 10 cents per kWh. The national average cost for electricity in the U.S. is about 10 cents per kWh, while the average residential rate is about 11.7 cents per kWh.

Electricity Costs for Charging If electricity costs $0.11 per kilowatt-hour, charging an EV with a 70-mile range (assuming a fully depleted 24 kWh battery) will cost about $2.64 to reach a full charge. This cost is about the same as operating an average central air conditioner for about 6 hours.

Cost to charge an electric car at home Most drivers will charge their electric car overnight, waking up to a full battery every morning. Average domestic electricity rate is about 14p per kWh.
1338144
For electric vehicles, this requires about 10 kWh of electricity (Most EVs average between 3 & 4 miles per kWh. Charging an EV at 40 A (9.6 kW) means it will take a little more than one hour to charge to the minimum required daily amount, compared to 1 hour and 20 minutes at 30 A (7.2 kW).
206515
A standard EV battery requires 30 kWh per 100 miles. 1 Using the average national residential utility rate of about 13 cents per kWh, we can find how much it costs to drive those 100 miles.

The average electricity cost in the UK is around 14p per kilowatt-hour (kWh). So, using a 3kW charger to fuly top up a Nissan Leaf with a 40kWh battery would take 13.3 hours, at a cost of £5.76. With the Nissan's quoted range of 168 miles, that amounts to just over 3p per mile.

Most computers are built to use up to 400 kilowatts of electricity per hour, but they usually use less than that. The average CPU uses about as many kilowatts per hour as the typical light bulb.

I.e. Assuming You have a typical full size auto battery, it is about 50 amp hours. To Calculate how much time You'll need to charge the battery with a 15 Watt solar charger You'll need: Calculate the Ampere per hour of the charger: 15 Watts /12 Volts = 1,25 Amperes.

The cost to charge an electric car in the UK varies between home, work and public charging. For a typical electric car with a 60kWh battery and ~200 mile range: Charging at home: Costs about £8.40 for a full charge.
1261842
To calculate the cost per mile of an EV, the cost of electricity (in dollars per kWh) and the efficiency of the vehicle (how much electricity is used to travel 100 miles) must be known. If electricity costs $0.11 per kWh and the vehicle consumes 34 kWh to travel 100 miles, the cost per mile is about $0.04.

Average emissions Combined with data on the sources that provided electricity to those regions in 2015, they found that the average electric vehicle is greener than the average new petrol car if the power grid emits less than 1100 grams of carbon dioxide per kilowatt hour.

"A home charging station costs between $800 - $2,000." In B.C., if power costs $0.10 per kilowatt-hour, an EV ends up costing about $0.016 per km, Argue says. "A rule of thumb is the cost to fuel an electric car is about an eighth of the cost of a gas-equivalent vehicle," Argue says.
227473
You also can work from the total kilowatt-hours it takes to recharge the EV's battery. If an EV requires 40 kWh to recharge a fully depleted battery, and the rate is 18 cents per kWh, that's $7.20 for a fill-up.
92038
The time it takes to charge an electric car can be as little as 30 minutes or more than 12 hours. This depends on the size of the battery and the speed of the charging point. A typical electric car (60kWh battery) takes just under 8 hours to charge from empty-to-full with a 7kW charging point.
478885
Most electric cars get between 3 and 4 miles per kWh. Drive 60 miles, and your electric car will probably require between 15–20 kWh to recharge. Power. Power measures how fast the energy is delivered.
