Ouartz showed the results of a study conducted by Vaziri Law Group, which checked which electric vehicles are the most unreliable in winter. A law firm providing support to accident victims has analyzed reduction of battery range of various electric cars, average number of winter accidents over three years, average charging time and battery capacity.
In cold weather, charging may take longer
One of the few disadvantages of electric carswhich are powered by lithium-ion batteries, is that in On cold days, batteries charge slowerwhich was severely felt by Tesla drivers last year. During freezing temperatures in Chicago this January, Tesla drivers formed huge lines and waited for hours to charge their cars.
In addition, low temperatures can significantly reduce the car’s range, which can be disastrous if you are going on a long route and the network of charging stations is not dense enough.
Construction of a lithium-ion battery
Lithium-ion cells are a stack of thin aluminum and copper foils interspersed. Copper foils are coated on both sides with a thin layer of graphite powder, while aluminum foils are coated with metallic powder. These may be iron and phosphorus oxides in LFP cells, manganese, cobalt and nickel oxides in NMC cells or other mixtures. The foils are separated by a thin plastic membrane. The whole thing is flooded with a small amount of liquid allowing lithium to flow between the foils.
Why does it take longer to load?
The low temperature causes the powders on both foils to harden, and the liquid with which they are soaked (i.e. electrolyte) thickens, which causes the entire process of lithium ions breaking out from the powder particles on one foil, flowing in the cold electrolyte and sticking into the powder particles on the other foil. takes much slower.
These are the electric car models that have the greatest problems in winter, according to a study by Vaziri Law Group:
The list of the seven worst models included three Tesla models. However, the worst rated was the Nissan Leaf.
7. Volkswagen e-Golf
6.BMW i3
5. Tesla Model S
4. Volkswagen ID.4
3. Tesla Model X
2. Tesla Model Y
1. Nissan Leaf
