How long is the battery life in electric cars? – Auto News

In our file that we started last week for electric vehicles, we tried to find answers to questions about these cars.

So much so that we focused on the cost of charging, the charging time that varies according to the place of charge, and the features of use on intercity roads, which create a question mark in the minds of many people who want to buy an electric car.

Although these three topics are among the most curious about electric cars in the researches, there are a few less known and curious points about cars with batteries.

These, on the other hand, stand out as the service life and replacement costs of the batteries, which are almost the heart of electric vehicles, and the maintenance costs of these cars.


Car brands, which introduce a new electric model day by day, give these cars an average of 8 years of warranty, unlike their models with internal combustion engines.

Although this warranty period, which has become the industry average, may seem tempting at first, it is necessary to look at the invisible part of the iceberg.

Lithium-ion batteries are used in many electric cars today. This type of battery, which is more energy-dense than nickel-based batteries, gives the car more range and at the same time allows it to be charged faster.

It has been revealed in the studies that this battery can maintain its first day features for 160 thousand kilometers.

Therefore, considering that brands give their electric cars a guarantee for 8 years, if more than 20 thousand kilometers are not driven per year, it may be possible to replace the battery under warranty if necessary.

Well, if the battery needs to be changed depending on the usage and the warranty conditions are not met, what kind of cost will it be? Let’s look at this now.


12 years ago, in 2010, when Volkswagen’s ‘diesel scandal’ had not yet erupted and the interest in electric cars was not as intense as today, electric car batteries cost about a thousand dollars per kilowatt-hour (kWh).

According to the report published by Bloomberg New Energy Finance at the end of 2020, lithium-ion battery prices decreased by 89 percent from 2010 to December 2020, to $137/kWh.

The research in question predicts that prices will drop to $100/kWh in 2023, and lithium-ion battery prices will drop to $73/kWh by 2030, when almost all brands will stop producing internal combustion engines.

In our examinations last week, we gave examples of a car with a battery capacity of 39.2 kWh, which is one of the few electrified models in Turkey that falls under the 10 percent SCT segment.

If we look at the battery prices on this model again, the price of the battery pack in this vehicle costs around 5 thousand 370 dollars, considering the current market figures.

For electric vehicles with more battery capacity, the prices will rise up to 25 thousand dollars.


While the battery is the biggest cost item for both the manufacturer and the consumer in electric cars, the other expenses that these vehicles will incur during use are at lower levels than cars with internal combustion engines.

To remember, we mentioned in the second part of our file that the cost of running electric cars is more affordable than diesel and gasoline cars.

Apart from being more affordable per kilometer, electric vehicles can also be economical because they have fewer moving parts than internal combustion engine vehicles.

In fact, the fact that the electric motor in these cars has a less complex structure than an internal combustion engine also reduces the possibility of aging and deterioration in the parts of electric vehicles.

Therefore, electric cars, which do not need operations such as oil change and gasket change like conventional cars, do not need high-cost engine maintenance due to the aging of internal combustion engines.

For example, the maintenance intervals of the electric car with a 39.2 kWh battery are announced as 15 thousand kilometers. It costs 24 thousand TL in total for the maintenance of this car up to 120 thousand kilometers at the authorized service.

The maintenance interval of the semi-hybrid version of the same car with a 1.6-liter diesel engine is also announced as 15 thousand kilometers, while the total cost of maintenance up to 120 thousand kilometers is more than 30 thousand TL.

As a result, although the maintenance costs of electric cars are cheaper than cars with internal combustion engines, it should be taken into account that due to the aging of the batteries of these cars, the charge holding capacity will decrease and the driving range will be shortened.

As we mentioned in the lines above, this process mostly starts after 160 thousand kilometers in electric vehicles.
