To calculate range, the battery size is divided by the consumption to arrive at a theoretical figure, which is what’s printed and advertised by the manufacturer as the certified range.
How is the range of an electric car determined?
The range of an electric vehicle depends first and foremost on the capacity of its lithium-ion battery, in other words the amount of electricity it is able to store. … The level of energy in the battery at a given moment therefore defines the remaining range of the electric vehicle.
What is EV range based on?
The reality of EV range
While a vehicle’s published range is based on standardized testing performed on a dynamometer in a test facility, EVs, like gas cars, perform differently in real-life conditions depending on terrain, passenger load, speed, driver behavior or outdoor temperature.
How do I increase my EV range?
10 Ways To Boost Your EV’s Range
- Drive Smoothly. Simply put, lead-footed driving will drain your EV’s battery at an accelerated rate. …
- Slow Down. Try to keep your speed under 60 mph whenever possible. …
- Maximize Regenerative Braking. …
- Go Easy On The Heat. …
- Be Cool With The AC. …
- Tend To Tires. …
- Travel Light. …
- Keep It Slick.
Why do electric cars have low top speed?
With electric cars, the emf available is limited by the battery emf. So, when the car reaches the maximum speed possible with the available emf, the speed can no longer be increased. Even before the maximum speed is reached, the power will drop off because of the limited available emf.
How accurate is EV range?
Real-world electric car range
From our real-world testing, we can deduce that these electric cars are actually capable of achieving around 85% of that quoted range. These numbers have been calculated using our own real-world testing of a Nissan Leaf, Volkswagen e-Golf, and Hyundai Kona Electric.
Does weather affect EV cars?
According to AAA’s “Cold Weather Can Cut Electric Car Range by Over 40%”, EVs often lose 12% of their range in cold weather, but the loss leaps to 41% with the heater on full blast.
How do you calculate EV battery?
Divide the distance travelled by the power used and you’re left with the number seven. Multiply that by the battery charge remaining (34kWh) and you’re left with 238km – which is your ‘distance to empty’ for the EV.
At what speed are electric cars most efficient?
Watch your speed
To an extent, the faster you go, the more energy you consume – the most efficient speed for electric cars is likely <10mph for most BEVs (depending on static consumption like air conditioning, heating and electrical systems) – though clearly we wouldn’t recommend driving that slow!
Do electric cars get better mileage on the highway?
For EVs, which tend to do better in stop-and-go driving, where regenerative braking can help contribute to the battery’s charge, city fuel efficiency is typically better than highway. That’s the reverse of most gasoline vehicles.
Does cruise control use more battery?
Use Cruise Control: Saves Battery On Flat Roads
Whether you drive an electric, petrol or diesel car, using cruise control can save on battery. Constant driving speed is highly correlated with higher fuel efficiency. This only applies to flat roads, however. On hilly roads cruise control can use more energy.
Why do electric cars need so much horsepower for higher speeds?
Efficiency Equals Horsepower
That’s because EVs have fewer moving parts, so they’re able to run more efficiently. … The instant torque and the simplified powertrain are the two factors that enable an electric vehicle to take off from a stop much faster than a gas vehicle of comparable power specs.
Which is the fastest electric car in the world?

How Long Will electric cars last?
Consumer Reports estimates the average EV battery pack’s lifespan to be at around 200,000 miles, which is nearly 17 years of use if driven 12,000 miles per year.
