Why Tesla And Other EV Ranges May Be Inaccurate

Published

on



Since the Environmental Protection Agency was founded in 1970, one of its primary tasks has been testing gas burning vehicles – both to see how much they pollute and to tell consumers how many miles per gallon they are liable to get in a car. But since electric vehicles came to market in significant numbers after 2010, the agency has been shifting toward telling consumers how much range they should expect to get on each car. The trouble is that EV technology is changing…fast. The agency has had decades to refine standards for gas burning cars, and just a few years for EVs. Some critics say the tests are inaccurate. CNBC went inside the EPA’s National Vehicle and Fuel Emissions Laboratory to find out how they test EVs.

    I would like to see battery/range degradation numbers for each vehicle, as a function of calendar aging and mileage. Even more useful would be an EPA approved website where I can select a car model and year, and then input various parameters (payload, outside temperature, typical driving speed, vehicle mileage, etc), and get a range estimate. The more parameters I enter, possibly the more accurate the result).

    Teslas are rated at 110-129 mpge… if newer models are only getting 75% of epa range, I’d expect it to be closer to 85-100 mpge

  5. @adventureswithfrodo2721

    Because they are giving FAKE results to hype their products. I saw one EV truck charging at a charging station and it was taking over 3 hours. They are only good for short trips.

    Great reporting. I drive a Tesla, and don't really have complaints on my range estimates. But I also recognize that EV motors are far more energy efficient. The huge battery pack is equivalent to just a few gallons of gas. So when something that could impact a car's range (regardless of power plant) it is felt more significantly on the battery with it's added energy efficiency. I also don't have range anxiety. I know that if my car shows that I have 20 miles of range, and my next charge is 10 miles away, there is little I could do 'wrong' to burn that extra 10 miles of range before I reach the charger. And the car does a great job of moving me to a closer charger if I am 200 miles away and it thinks I won't make it to a charger that is too close to that stated range.

    I want a real world test of range. With the batteries at 100%, drive from Columbus to Indianapolis on I70 at posted speed limits, with the AC or heat on like a normal person. To and back.

  8. @Sanjay9442

    December 21, 2023 at 1:15 am

    They can do all the fancy talk but EPA range does not mean anything to a consumer. My model 3 EPA rated for 310 miles will give 240 miles.

  9. @jasonrhl

    December 21, 2023 at 1:15 am

    HMm, with the ability to send data to manufacturer why don't we use real drivers results to create a real world result? I assume once you get a few hundred cars running you might get a good sample.

  10. @user-pl5dq1kf6z

    December 21, 2023 at 1:15 am

    I would like to know what they consider as range.; The vehicle is at a dead stop in the middle of the road ? Nobody in their right would drive an ICE car like that. On my car I only need to see when the low fuel warning lite goes on and I am good for 50km. for sure at normal power.

  11. @angryhd2976

    December 21, 2023 at 1:15 am

    The heavier your foot the less range you have.

  12. @dmitri9888

    December 21, 2023 at 1:15 am

    Have Tesla Y = 330M spec range -> can make it driving 55, if to drive as usual 90-100 -> range closer to 160M

  13. @JayGrant-hi5ms

    December 21, 2023 at 1:15 am

    Can’t wait until the EPA tests ranges for the Aptera. 400 mile variant to start and eventually up to 1,000 miles per charge.

  14. @cyberslim7955

    EVs should have a city and hwy rating. They peform poorly under load ; such as drving at freeway speeds. A Rivian was driven towing a trailered mustang 2400 miles across the US. It had to stop every 120 miles to charge for an hour; that is 3 hours to travel 120 miles or 40mph. The EPA rating was 350 miles – EPA= biased liars.

  16. @brasi-blade7705

    December 21, 2023 at 1:15 am

    Anyone know if aftermarket performance companies can elect to have the EPA test a car modified with their device? We have a device that we believe will improve both fuel economy and emissions over factory. How would you go about approaching the EPA on getting an official test done and how much would it cost?

  17. @Custo911

    December 21, 2023 at 1:15 am

    Jessssus. Get a Tesla and no range anxiety. This is a term for companies that don't have charging infrastructure.

    Epa tests average usage and by far most time spent by people is inside the city not on highways.

    December 21, 2023 at 1:15 am

    Of course, companies tend to exaggerate range than actual mileage especially Tesla models . I mean the gap between Tesla claims and EPA testing are getting smaller but there is still big difference. I trust EPA .

  20. @teddlister3350

    December 21, 2023 at 1:15 am

    I just completed a cross-country round trip, I think the US needs to examine dropping the speed limit closer to where it was in the 1980s. Save lives and energy.

  21. @billual

    December 21, 2023 at 1:15 am

    Why do you always put Tesla in the front space of anything that is derogatory about. I don't own a Tesla but I think most people have realize that the Tesla's go father on a charge than the range they advertise. You continually badmouth Tesla I am wondering why

  22. @DanielPearson1

    December 21, 2023 at 1:15 am

    "EVs… Don't emit pollutants". This is false, EVs emit far more brake and tire pollutants than ICE cars, and these are very harmful to the environment and human health.

  23. @timthetoolman223

    December 21, 2023 at 1:15 am

    If EV owners suffer from range anxiety now just wait until trade-in anxiety hits them when they find how little they'll get for a their used EV when they decide to get rid it.

  24. @JoshuaDay

    December 21, 2023 at 1:15 am

    Basically, the EPA need to consult with Bjørn Nyland (Teslabjørn) to get a good system nailed down.

  25. @harveysmith4424

    December 21, 2023 at 1:15 am

    Range anxiety will truly be gone, once charging stations are as ubiquitous as gas stations. IMO the range of the vehicles aren't the problem but access to plentiful charging stations.

    0:26: 🚗 Electric vehicles (EVs) are gaining popularity in the US, but there are concerns about the accuracy of their range estimates.

    3:27: 🚗 The EPA tests cars to ensure they meet regulations and collects data for other agencies.

    6:51: 🚗 The EPA faces challenges in testing electric vehicles due to the complexity of factors like battery depletion, real-world driving conditions, and heating/cooling systems.

    9:32: 🚗 The way electric vehicle (EV) range is tested and reported can lead to discrepancies between lab results and real-world driving, causing range anxiety for drivers.

    12:46: 🚗 Car and driver testing data shows that EVs fall short of their range numbers by 12.5% on average, and the range can vary depending on driving conditions.

    16:19: 🚗 Automakers have a history of pushing against regulations, as seen in the Dieselgate scandal, but the focus is now on electric vehicles and ensuring they are environmentally friendly.

    The problem is nobody is doing real world testing, it's all in a lab like the E.P.A. lab. Not realistic.

    If a Tesla, you have t assume only one half. If Elon say 400, it really means 200. Just cut in half.

    EV's aren't just worse on the highway. They are abysmal on the highway. Range anxiety is not a thing. Its time anxiety. When you factor in the time, the cost per mile highway on an EV is roughly equivalent to a 1 ton gas truck. It is atrocious. EV's are great in the City, being roughly on par with 25+ mile all electric range PHEV's. Hybrids continue to be the lowest total city and highway cost per mile vehicles. Additionally performing cold and hot tests would greatly lower EV city and highway and PHEV city only economy. ICE and Hybrids will mostly retain their numbers. The EPA should rate in cost per mile and just use the national average kWh, gas, and diesel prices at the time, and should definitely factor in time for highway. It is not apples to apples to allow the EV to take a 30 minute break to charge every couple hundred miles while requiring the Hybrid, PHEV, and ICE to mush on. Total time of trip matters.

    This proto – industrial system was thus part of a network of commercial exchanges. It was controlled by members and goods were produced by a vast number of producers working within their family farms,not in factories. At each stage of production 20 to,25. Workers were employed by each merchants. This meant that each clothier was controlling hundreds of workers. 👍👍👍👍👍

  38. @Rhaman68

    December 21, 2023 at 1:15 am

    This discussion has no resolution. The variables factors are many. Take two identical F-150 trim level, engine, etc. trucks and one driver’s aggressive technique shall render an mpg up to 50% less than a driver with moderate technique. Change that to range and, just using numbers, a 300 mile truck shall have a 150 mile range. The reason to have EPA test under lab conditions is for consumers to have a comparison basis. I doubt any pickup owner selects the brand, model and trim level based on MPG test results. Take two Tesla Model Y’s and follow suit as to one driver cruising at 65 mph, in flat terrain, the other drives at 85 mph in hilly terrain. Range estimates from the lab go away. The range estimator in the car adjusts based on history. It’s not inaccuracy as to the software!

    What's the big deal about a 350-mile range EV? 350 miles is a distance greater than the distance between Raleigh, North Carolina and Savannah Georgia. Most people don't make that kind of a commute in a day, so with the potential for overnight charging at one's home or apartment: 350 miles should suit most people.

    Personally, if I had to go 350+ miles to get somewhere: I would take a plane.

    Ev's ranges are dramatically exaggerated offical figure's are no where near actual range in daily driving especially in adverse weather ev's have a place in motoring but are no where near ready to replace ice when everything is taken into consideration rushing ev's is the wrong way forward and the 2030 ban in new ice cars is madness no doubt most of them or their components will be made in China currently ev's are also way too expensive for everyday folk and they're no more environmentally friendly than ice unless you drive massive mileage even then it's not clear politicians need to rethink

Taylor Farms has been linked to cyclosporiasis and salmonella outbreaks this summer. After years of consolidation, experts say the company’s ability to control every stage of the supply chain has made it indispensable to grocers and restaurant chains, while raising the stakes for consumers when things go wrong. CNBC food and wellness reporter Brandon Gomez explains how the U.S. became so reliant on Taylor Farms.
