how much power does an electric car use?
159394
An average electric car consumes approximately 0,20 kWh/km. On favourable weather conditions the consumption can be even 0,15 kWh or less, but year-around average in most countries is closer to 0,2 kilowatthours.
677261
Electric vehicles are all about low running costs and emissions and win out against hybrids on both counts. Pure electric vehicles can have a range of up to 325 miles, with an average of 194 miles on a single charge.
545027
Cars use DC, Direct Current. That's the type of electricity produced by batteries, and it flows in one constant direction.
78258
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.

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.

A typical electric car (60kWh battery) takes just under 8 hours to charge from empty-to-full with a 7kW charging point. Most drivers top up charge rather than waiting for their battery to recharge from empty-to-full. For many electric cars, you can add up to 100 miles of range in ~35 minutes with a 50kW rapid charger.

The average cost of electricity in the US is $0.1285/kWh, meaning it costs only $5.14 on average to recharge your Nissan Leaf to the full 149-mile range.

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.

Plug-in hybrids may drive for 10-50 miles using only electricity before they start using gasoline, and can then drive for about 300 miles (depending on the size of the fuel tank, just like any other car). Most electric vehicles are currently capable of about 100 miles of driving before they need to be recharged.

That will vary, depending on the state-of-charge of the battery when you go to charge it. But as a guide, Tesla batteries range from about 65 kWh to 100 kWh. To fully charge a dead-flat 100 kWh battery will take 100 kWh's of electricity (100 units on your utility bill).
232594
The rule of thumb number used for energy required for EVs in normal driving is 25 KWH for 100 miles. Large cars will need more and small cars will need less.
1288311
Electric-car Motors and Batteries. Electric cars can use AC or DC motors: If the motor is a DC motor, then it may run on anything from 96 to 192 volts. Many of the DC motors used in electric cars come from the electric forklift industry.
421937
Electric cars vs petrol cars With the average UK electricity price sitting at around 14p per kWh and if you assume an electric car will travel 3.5 miles per kWh on average, to travel 100 miles would cost around £4 or 4p per mile.

How much does it cost to charge the Nissan Leaf? The average cost of electricity in the US is $0.1285/kWh, meaning it costs only $5.14 on average to recharge your Nissan Leaf to the full 149-mile range.

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.
951067
Although the Superchargers are technically capable of 150 kW, Tesla cars restricted the power to 120 kW, but boosted that to up to 150 kW for the Model 3 Long Range and the 100 kWh versions of Models S and X in 2019.
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.
