How Is The Battery Condition Of An Electric Car After More Than 10 Years Of Use?

JAKARTA - Many owners or potential buyers question the negligence of the electric car battery they own or want to buy. When the battery degrades, the battery loses its functional capacity, and this decrease is due to the age of the vehicle battery and based on the distance.

However, the decline in battery capacity is apparently not significant for the Tesla giants. This electric car manufacturer from the United States has revealed interesting data regarding the condition of the car battery used in the Model S sedan and Model X SUV after long used by the owner.

It is known that the Tesla Model S has been circulating since 2012 and the Model X SUV has been circulating since 2016, so Tesla has enough time to analyze batteries on its cars and track how the battery's capabilities have decreased over time, reported by Motortrend, Thursday, April 27.

In a company report in 2022, Tesla even claims that it still has up to 88 percent capacity of Model S battery power and 90 percent of Model X or is still well maintained after being used for about 200,000 miles or 321,868 km.

According to Tesla, the reduction in battery power is not only influenced by the distance, but also by the number of charging cycles and usage times. Nonetheless, Tesla's analytical results show that the use of batteries on the Model S and X is fairly reliable, and it is likely not necessary to replace the overall battery on Tesla vehicles in the future.

Model S and Model X use different types of battery chemistry with Model 3 and Model Y. And Panasonic is the main supplier of the 1865 NCA lithium-ion battery for the larger Tesla electric cars.

In a recent calculation of InsideEVs, from the Tesla data above, battery power decreased by 12 percent in 200,000 miles of travel, it means losing about 1 percent of power every 16,667 miles (26,817 km) or every 67 charging cycles (assuming a distance of 250 miles per cycle).
