Although efforts continue to make electric cars widespread, some chronic problems exasperate drivers. Users complain about the decreasing range of vehicles, especially in winter months.
Driving a car during the winter months quite troublesome It can become. This may be especially obvious for people who use electric vehicles. When we look at the reactions, we see that the range of electric vehicles has decreased and they have difficulty in charging.
The complaints of some people who own electric cars are as follows:
“It must be the greatest irony I have ever seen that electric cars are brought to car dealerships on the backs of gasoline-powered tow trucks to replace their frozen batteries.”
“There are 91,000 electric car owners in Illinois who cannot use their vehicles for more than a few minutes a day. It is too cold to hold a charge and it takes two hours to charge.
Before investing in electric cars, you need a garage and knowledge of how to preheat the battery. “For my part, I’ll stick with what works—gasoline.”
“Don’t electric vehicles work in the cold? Don’t say that…”
Especially those who do not have a charging unit at home are experiencing problems.
Ranges of electric vehicles are already limited in cold weather not too highrange of most urban models 250-300 kilometers It is somewhere in the band. People who need to cover a certain distance continuously during the day therefore have to constantly charge their vehicles. There are some reasons for this situation.
Most electric cars have lithium-ion batteries. Lithium Since it is a very light and low-energy element, electron movements slow down extremely in cold weather. Liquefied lithium ion also begins to solidify, which is accompanied by viscosity It is said. More viscosity means more resistance. More resistance means longer charging time and less efficient energy transfer. In summary, as the weather gets colder, starting the car becomes more difficult for the battery.
Manufacturers such as Tesla also test vehicles before they are started. bringing it to the appropriate temperature suggests. Warming up the vehicle also increases battery performance, but requires spending energy in the battery. So the vehicle needs to warm itself up first. Of course, this problem is not a major obstacle to the transition to electric vehicles, but simply represents a step in our learning curve to drive electric cars. While battery complaints are already coming from countries such as the USA Norway The fact that countries like these do not experience such a problem reveals the situation.
