Is 4 miles per kWh good?
Just take the miles per kWh figure and multiply by 40. So an efficient 4 miles per kWh electric car is the equivalent of a 160 MPG car. Even a relatively inefficient electric car offering 2.5 miles per kWh would be the equivalent of 100 MPG in a petrol or diesel car.
How far can you drive on 1 kWh?
An electric car’s efficiency is based on the number of miles that the car goes on a single kilowatt-hour (kWh). An efficient EV can go about four miles per kilowatt-hour. Sometimes that is indicated by how many kWh are used to go a single mile. Consumers should not be concerned about the longevity of an EV battery.
How many kWh is 100 miles?
Kilowatt-hours is the standard energy unit for electricity. In simplified terms, if an electric vehicle can travel 100 miles on 33.7 kWh of electricity, the EPA rates it at 100 MPGe. As you can see, this would be a very efficient vehicle, because a gas car would have to travel 100 miles per gallon to be equivalent.
How much electricity does an electric car use per mile?
If electricity costs $0.13 per kWh and the vehicle consumes 33 kWh to travel 100 miles, the cost per mile is about $0.04. If electricity costs $0.13 per kilowatt-hour, charging an EV with a 200-mile range (assuming a fully depleted 66 kWh battery) will cost about $9 to reach a full charge.
How many kilowatts does a Tesla use per mile?
An average Tesla uses 34 kWh of electricity per 100 miles. This equates to about 34,000 kWh per 100,000 miles, or between 102,000 kWh to 170,000 kWh for the lifespan of the vehicle. Tesla vehicles charge at about 94% efficiency and discharge at about 90% efficiency.
What does WH mile mean?
Whether it shows up there as watt-hours per mile (Wh/mi), as Tesla prefers, or miles per kilowatt-hour (kWh), employed by many other EVs, drivers want to know how much energy their cars consumed over how many miles—and what that means for their next trip.
How many kWh per day is normal?
According to the EIA, in 2017, the average annual electricity consumption for a U.S. residential home customer was 10,399 kilowatt hours (kWh), an average of 867 kWh per month. That means the average household electricity consumption kWh per day is 28.9 kWh (867 kWh / 30 days).
How many kWh is 20 miles?
Mile Per Kilowatt-hour to Kilowatt-hour Per 100 Miles Conversion Table
| Miles Per Kilowatt-hour | Kilowatt-hours Per 100 Miles |
|---|---|
| 18 mi/kWh | 5.5556 kWh/100mi |
| 19 mi/kWh | 5.2632 kWh/100mi |
| 20 mi/kWh | 5 kWh/100mi |
| 21 mi/kWh | 4.7619 kWh/100mi |
How many miles does an electric car battery last?
While experts estimate the average EV battery will last around 200,000 miles, some manufacturers already promise much more than that. And the news gets better: Tesla has their sights set on a million-mile battery, and claims that they are not far from achieving this goal.
How do I calculate kWh from range?
Range refers to how far a vehicle can go on a single charge. Range is calculated by dividing the amount of energy in the batteries (kWh) by the efficiency of the vehicle (kWh/mile).
How do I calculate kWh?
The “kilowatt-hours” you see on your power bill expresses the amount of power that you consumed in a month. To calculate the kWh for a specific appliance, multiply the power rating (watts) of the appliance by the amount of time (hrs) you use the appliance and divide by 1000.
What are kilowatts per hour?
A kilowatt-hour measures the energy an appliance uses in kilowatts per hour. For example, if you clean your floors with a 1,000-watt vacuum cleaner for one hour, you consume 1 kWh of energy. Your kilowatt-hour consumption factors in how many watts your appliances use and how often you use them.
How many kWh does it take to drive 100km?
In EVs, it’s kilowatt-hours — hence the Tesla Model 3 Standard Range Plus’ official rating of 14.9 kWh per 100 kilometres. Substitute free electrons (kWh per 100 kilometres) for 93 octane (the L/100 kilometres we’re all familiar with) and the ratings are virtually identical.
Is electric cheaper than gas per mile?
A: The cost per mile of an electric car is less than the operating cost of a gas car, with most reporting at 4 to 5 cents per mile.
How many kWh does an EV use per year?
According to the Federal Highway Administration, the average American travels nearly 13,500 vehicle miles per year. At that level of driving, most EVs will require around 4,000 kWh of electricity per year to operate.
How much electricity does a TV use?
Modern TVs use, on average, 58.6 watts when in On mode and 1.3 watts in standby mode. The power consumption of modern TVs ranges from 10W to 117W (0.5W to 3W on standby). On average, TVs consume 106.9 kWh of electricity per year, costing $16.04 annually to run in the US.
Is it cheaper to charge Tesla at home or at supercharger?
Is it cheaper to charge with a Supercharger or charge at home? In almost all cases, charging your Tesla at home is going to save you the most money, since Superchargers tend to bill at a higher rate per-kWh than your utility does.
Does owning a Tesla increase your electric bill?
Unlike the (relatively) low energy consumed by your smartphone and laptop, your Tesla will devour energy — putting some significant strain on your energy bill. Sure, owning an electric car is clearly less expensive to “fuel” than an equivalent internal combustion engine (ICE) vehicle, but it’s not free.

Are electric cars more efficient than gas cars?
Advantages of electric cars
AEVs are far more efficient than conventional gas-powered vehicles: AEV batteries convert 59 to 62 percent of energy into vehicle movement while gas powered vehicles only convert between 17 and 21 percent.
