About electric vehicles goes a lot of tales. For example, many believe that in winter, electric vehicles use virtually impossible that they are cold, they are slow and so on. Many often blame such machines is that in three years the battery capacity will drop almost by half, and the owner will get on expensive replacement batteries.
This opinion was formed against the backdrop of even more ancient claims that lithium-ion batteries on average live a year or two (about 500 cycles charge-discharge), after which their capacity drops sharply.
However, this is no longer the case. In the case of smartphones, and in the case of electric vehicles. This proves fresh statistics for 350 cars Tesla.
The results of the study, I think, will surprise many of you. It turned out that the average for the first 80 thousand km the batteries lose about 5% capacity. And if the rate of degradation remained, after 300 thousand miles the battery would have lost 25% of its original capacity, but in reality, after this run the battery loses less than 10% capacity!
According to the schedule in the database there are data on vehicles that passed 400 thousand km and more. Their performance also falls within the average range.
Tesla itself claims that conducted the modeling, which showed that even after 800 thousand km of battery machines, the company will retain about 80% original capacity.
The original article also noted that his own Tesla Model S Dating back to the first batch of 2000 machines, after five years lost only 6% of the battery’s capacity.
Given that even 300 thousand miles — a huge mileage, which most cars approach only in 10-15 years, think about the problem of degradation of the battery in the Tesla is just not worth it.
However, this does not mean that the same situation is true for all electric vehicles on the market. For example, the original Nissan Leaf, according to the source, on average over the five years it lost about 20% of the battery’s capacity.
