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.

Some rely much more on electric power than others. ... When running in electric-only mode, PHEVs have no tailpipe emissions. With plug-ins, your driving habits have a huge impact on the annual running cost. If you do mostly short trips (30-50 km) and have a place to plug in overnight, a PHEV makes sense.

According to the US Department of Energy's Office of Energy Efficiency and Renewable Energy, “EVs convert about 59%–62% of the electrical energy from the grid to power at the wheels. Conventional gasoline vehicles only convert about 17%–21% of the energy stored in gasoline to power at the wheels.”

The long-range version of the Model 3 has a 75 kWh battery pack with a 322 mile range. If we still assume the average national electric pricing of 13 cents per kWh and a charging efficiency of 85%, then a full charge will cost $11.47. This is $3.60 per 100 miles of mixed city and freeway driving, or 3.6 cents per mile.

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.

For this case, let's take into account a 120 volt charger that draws 10 amps. Volts multiplied by amps yields watts as the product, so the result is 1,200 watts. Divide 1.2 kilowatts by an hour and an electric golf cart consumes about 1.2 kWH.

That figure will tell you the cost per 100 miles. 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.

When fully charged, you will pay about 4.0¢ per mile for the first 48 miles you drive ($1.92 for the electricity and $. 00 for the gasoline). After the first 48 miles, the vehicle will function like a regular hybrid and consume only gasoline, costing about 5.2¢/mile. You will spend $1.01 on electricity and $.

There is a direct conversion between horsepower and watts: 745.7 watts is 1 horsepower. Car motors for modern vehicles range from about 50 horsepower to 500 horsepower or more. An average medium size family car might have a 150 HP motor. To duplicate that with an electric motor you would need 111,855 watts of power.

The new Volt is one of the most efficient plug-in hybrids around, offering: 1,100 miles between fill-ups when you charge it regularly. Up to 53-mile battery range to more than cover the 40-mile round trip of an average daily commute. Up to 420 miles of total range with a full charge.

Many people question how green electricity production required to power an electric car really is. Research by the European Energy Agency found that, even with electricity generation, the carbon emissions of an electric car are around 17 – 30% lower than driving a petrol or diesel car.

A Chevrolet Bolt, which is EPA-rated at 28 kWh/100 miles and is one of the more efficient EVs available, would need at least a 3.5-kW system to get 50 miles of range per daily charge. Such a system costs about $7,000 and doesn't include the cost of a storage battery to hold power for overnight charging.

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.

Only electric cars and plug-in hybrids that meet set criteria qualify for the cleaner vehicle discount from the London Congestion Charge. To qualify for exemption, a plug-in hybrid has to have CO2 emissions of no more than 75g/km and an electric-only range of at least 20 miles.
