As he said, the WLTP test is “better than the old NEDC, but still not exactly realistic”, the test itself takes only 30 minutes and the average speed achieved is only 28.9mph. is.
It is divided into low speed, medium speed, high speed, and ultra high speed tests, with average speeds of 11.7mph, 24.5mph, 35.2mph, and 57.2mph, respectively, and the tests are set to simulate real driving. Because it has been done. By increasing or decreasing the speed, there are benefits to electric vehicles that can use regenerative braking to charge the battery in such situations.
As an aside, he pointed out that the actual range that is regularly obtained from the utility car is about 78% of the WLTP range. Fortunately, this is in close agreement with the findings based on the road test above. ..
How do I know the full range of EVs before I buy them?
Don’t forget to check the quoted range numbers provided by the manufacturer in more detail. The numbers in the range of headings that are displayed in most cases are the numbers for the WLTP combination. That is, the average based on the entire test.
However, what is available to the manufacturer (although not always public) is a range of numbers based on the various components of the test. So, for example, EVs have WLTP low-range numbers that estimate the range based on low-speed use, and WLTP ultra-high numbers that do the same for high-speed use.
With that in mind, our experts suggest that if you use EVs regularly on the highway, you can explore the range based on the ultra-high speed section of the test. Similarly, if you are driving primarily in urban areas, you can use low or medium range numbers to better understand what the range will be for a particular application.
If the manufacturer does not publish these numbers, please contact your sales representative. The more people you ask, the more likely these numbers will be published and mainstream. This will make it easier for buyers to see the actual range in the future.
Our experts also suggest looking up facts and numbers in an independent website EV database. “I think they’re getting data from one of the sites that holds all EU vehicle type approval data, including emission data for all new cars,” he said.
“They asked some manufacturers some problems early on, as people looked at their dataset and questioned the official numbers they had to (legally) cite. Caused. But in reality, the numbers quoted by the EV database seem very realistic. “
The truth about electric cars
First of all, it is important to remember that the numbers in the range that the manufacturer is obliged to publish by law do not necessarily indicate the actual range. This is because the official tests used tend to flatten electric vehicles (although these numbers will continue to be useful for comparison purposes). ).
It’s also worth remembering that frequent use, up and down hills, and cold weather without pre-adjustment can reduce the EV’s range by half. , This is probably the worst scenario.
Based on our experience and road tests, the rule of thumb is to expect to achieve 75-80% of the car’s WLTP coupling range in the real world. However, this is not guaranteed and is the number of factors such as ambient temperature, speed, terrain and number of passengers.
However, before making a purchase, ask your retailer to provide low and ultra-high numbers as well as the combined range. This will give you a better idea of how far your car will travel long distances or throughout the city. I think you will use it the most.
