Misinformation and unfounded claims about electric vehicles continue to occupy a wide space on the internet. Following claims such as the inadequacy of the charging infrastructure of electric vehicles or the inability of the electricity grid to withstand mass charging demand, the “battery life” debate is now on the agenda. However, a new study has once again revealed how baseless such rumors are.

Claims that the batteries of electric vehicles wear out quickly and need to be replaced within a few years are frequently expressed. Such statements that the cost of battery replacement reaches tens of thousands of dollars trigger the fear that electric vehicles will lose value in the second-hand market.

Battery health examined with real data

P3 consulting firm, which took action to analyze the durability and lifespan of electric vehicle batteries in detail, carried out one of the most comprehensive studies to date. Within the scope of the study, 50 vehicles in the company’s own fleet were examined. Later Data from more than 7,000 electric vehicles analyzed.

P3 conducted this study in collaboration with Austria-based battery diagnostics company Aviloo. Aviloo has performed more than 60,000 capacity tests to date and examined the battery performance of vehicles in detail. The data obtained, Vehicles with more than 300,000 kilometers It also includes. This is almost double the 160,000 kilometer warranty offered by most electric vehicle manufacturers.

Capacity loss in 15 years is only 13 percent

On the other hand, the research results are quite clear: Electric vehicle batteries in the first 30,000 kilometers quickly 95 percent falls to the level. However, after this point, the decline in battery health slows down and to 100,000 kilometers battery capacity when reached average 90 percent remains at the level. 200,000 to 300,000 kilometers This ratio is between 87 percentIt decreases to .

Roughly speaking, the range of an electric vehicle with a range of 1000 kilometers decreases to 870 kilometers after 300,000 kilometers. An average driver in Turkey travels 20,000 kilometers a year. Therefore, the battery of this driver’s electric vehicle will have lost 13 percent of its range after 15 years.

According to experts, the reason for the rapid capacity loss in the first period is the SEI (solid electrolyte interphase) layer formed in the anode part of the battery. Losses caused by this chemical reaction occur as a natural process in the initial stages of use of the battery. However, in the long run, this situation balances out and the performance of the battery remains stable.

How to extend the life of electric vehicle batteries?

Usage habits are of great importance to extend the battery life of electric vehicles. In fact, the ideal use is not difficult at all and it is not complicated to do. In fact, if you basically know how to use your smartphone battery, very similar things apply to vehicles. Battery management systems of manufacturers such as these have an important share. A vehicle with a good battery management system will tolerate driver errors. P3 lists the points to consider in this regard as follows:

Protect the battery from extreme temperatures

  • Batteries should be kept at low to moderate temperatures (below 25°C) when not in use.
  • Temperatures above 60°C accelerate chemical reactions, increasing capacity loss.

Choose a low charge level when parked for long periods of time

  • If the vehicle will be parked for a long time, the battery charge level should be between 10% and 50%.
  • Higher charge levels can lead to higher voltage in the cells, accelerating battery aging.

Avoid high current situations

  • Situations that require high current, such as DC fast charging, heavy acceleration or high-speed driving, negatively affect battery health, especially in extreme temperatures.
  • To extend the life of the battery, choose slow charging methods and gentle driving style.

Battery warranty period and beyond

  • Most electric vehicle batteries are warrantied for 8 years or 160,000 kilometers, and beyond that time they generally work fine, as studies have shown.
  • Even when the warranty period has expired or it no longer meets the desired performance, the battery can be used in energy storage systems called “second life”.

Second use before recycling

  • Batteries can usually be used for 20 years or more. Once their initial lifespan is completed, they may still have a valuable lifespan compared to new ones.
  • However, recycling it after the second use is the best choice.
