Many electric car owners do not have to worry about having too many fast chargers while driving long distances; Unfortunately, the problem of relentless slowdown from high-speed travel on highways does not end. An article in the Financial Times published the story of a Nissan Leaf driver who used 4-speed fast chargers with bad battery effects. This was a sad blow to Nissan's lead at the start of the development of battery power. Its choice of air conditioning technology does not seem to be a problem for many recent sedans that use only battery and SUVs. David Greenwood of the University of Warwick in Britain points out that the design of the Leaf, which has a small battery and is relatively inexpensive, makes it ideal for travel. Its limited cooling capability enables extreme heat and fast charging, unlike battery technology in more expensive cars like Teslas or Jaguar Pace with efficient battery cooling that can easily handle faster charging. But the devastating shortage of electric vehicles is still driving at a tremendous rate, a problem that dares to speak of its name. I will still learn from the manufacturer that there may be a large penalty for speeding for a long time with an electric car, although there are many claims that exaggerate the battery capacity sometimes by more than 30%.
British expert Nickmolden, chief executive of Emissions Analytics, admits that it has shown a 80 mph cruise ship, common in Britain, producing significant fines. Potential buyers of electric vehicles are not informed that as soon as they increase their speed above 60 mph, the range will start to shrink, and on the European continent usually at a speed of 130 km / h (81.25 mph) will disappear at an alarming rate. In Britain, the speed limit is 70 mph on highways, and in the real world this is around 80 mph and there is no doubt that the same route is being carried out in Europe, except in Germany where large pieces of automotive system do not. have a speed limit at all.
My data shows that most modern electric cars, driven on highways at speeds close to 75 mph, will cost a little more than 30% compared to the available range. In other words, if the width is 100 miles, do not expect to go farther than 65 miles. Other models such as the Nissan Leaf 62 kWh, Fiat 500e 42 kWh, Vauxhall Corsa 50 kWh and Polestar 2 78 kWh will not get you 50% off the road.
Professor Greenwood points out that electric motor drivers operate under different conditions that will produce different performance, while hot or cold weather may interfere with their operation. the whole work list. The implication is that the range will be much lower at higher road speeds than at lower road speeds - simply because it takes more energy per kilometer at a higher speed than at lower speeds due to the speed of the car. fast, ”said Greenwood in an email exchange.
