This is how electric cars cheat their owners



[ad_1]

When electric cars came full circle a few years ago, we also got a new concept: range anxiety.

A word that in a short time has become commonplace. At least for the part of the population that has an electric car. And there are not so few, here in the country of electric cars Norway.

To get the best possible range, in addition to a large battery, you must have low power consumption. Exactly the same as in a gasoline or diesel car, except that liters have been replaced by kWt in an electric car.

Can you trust the consumption meter?

One thing is still different. You can buy gasoline and diesel in almost every corner, and it takes between 3 and 4 minutes to fill the tank. In electric cars it is still not so good. There are fewer charging points and it takes longer to fill up.

Electric cars have a front meter.  Now it turns out that these correspond quite badly with reality.

This is exactly what makes electrical conductors more concerned with consumption and autonomy. Most electric cars are also equipped with clear consumption meters and an instrument that shows how far we go with the kilowatts you have on board. It’s good, so you can see if you go all the way.

Because you can trust these meters, right?

I study German

A new study by the German ADAC, which is a consumer organization similar to our NAF, shows that one cannot necessarily trust it. There are great differences from one brand to another in terms of the reliability of these consumption meters.

Because just like gasoline and diesel cars, these meters measure incorrectly. And according to the ADAC study, which has tested 15 different models of electric cars, electric car meters show even more errors.

All the cars traveled the same route and therefore the same length. Then charge all electric cars at the same temperature, with the same charger. Here the amount of electricity that reached the car was measured, thus obtaining the actual energy consumption, including the losses in the car charger. The head loss is around five percent.

Optimistic tesla

These are the discrepancies:

  • Long Range Tesla Model 3: 25%
  • Seat Mii Electric: twenty-one%
  • Renault ZOE ZE50 R135: 19%
  • Renault ZOE ZE50 R110: 18%
  • Tesla Model 3 Std Range Plus: 18%
  • Nissan Leaf e + (62 kWh): 18%
  • Jaguar i-Pace: 17%
  • Mercedes EQC 400 4Matic: sixteen%
  • VW E-Up !: sixteen%
  • Mini Cooper SE: fifteen%
  • Audi e-tron 55 fire: 14%
  • Hyundai IONIQ Electric: 12%
  • KIA e-Soul (64 kWh): 12%
  • BMW i3 120 Ah: 12%
  • KIA e-Niro (64 kWh): 9%

Even with the head losses included, it is surprising that none of the electric cars show exactly how much energy they use. All electric cars show too low energy consumption.

Inaccurate consumption measurements are interesting, as many electric car owners share consumption figures and compare between car brands.

Most optimistic is the consumption meter on the Tesla Model 3 Long Range, which indicates 25 percent lower power consumption than what ADAC actually measures in the car. Then follows Renault Zoe and Seat Mii Electric.

The best when it comes to showing the correct consumption is the Kia e-Niro. But even in this case, the car’s consumption meter “fails” with a consumption that is nine percent lower than the actual consumption.

Electric car owners are thus fooled by their own cars.
