Tesla Model Y Reaches 100,000 Miles: Pondering Estimated Lifespan Remaining
In the realm of electric vehicles (EVs), concerns about battery longevity have been a recurring topic. However, a closer look at real-world scenarios paints a different picture.
Chris Johnston, an industry expert with decades of experience in telematics, mobile computing, and wireless communications, has been shedding light on this issue. Johnston, who holds a B.S. in electrical engineering from Purdue University and an MBA, can be found on LinkedIn and followed on X at ChrisJohnstonEV. He is also the author of "The Arrival of The Electric Car," and focuses on electric vehicles in his coverage on Torque News.
One of the common fears about EV batteries is their lifespan. Most experts agree that these batteries are built to last between 100,000 and 200,000 miles, or about 10 to 20 years, depending on climate, charging habits, and luck. However, anecdotal evidence suggests that EV batteries can last even longer.
For instance, a Tesla Model X 90D reached over 300,000 miles before being replaced under warranty, and a city's taxi firm exclusively using Teslas has vehicles with over 450,000 kilometers [over 270k miles] and some with over 900,000 kilometers [over 560k miles]. Similarly, Tracee Hightower's Tesla Model Y has approximately 160,000 kilometers, and the battery has so far held up very well with minimal degradation.
Jeff Williams, a Tesla Model Y owner, reported that his friend's Model 3 with 267,000 miles has brakes at 50% and no major repairs needed. A Tesla Model 3 with over 217,000 miles had 88.5% battery capacity and over 300 miles of range, despite being used as a taxi and frequently supercharged throughout its life.
Tesla's internal data show that after 200,000 miles, Model Y batteries typically lose just 12-15% capacity, meaning they retain 85-88% of original capability. This evidence of durability is a testament to the advancements in EV battery technology.
While the cost of potential battery replacement in the future can be a concern, it's important to note that battery failure in EVs is expensive, but it's also rare, and prices are steadily dropping. As technology continues to evolve, we can expect to see even more improvements in battery longevity and affordability.
In conclusion, while the fear about EV battery longevity is real, so is the evidence of durability. As more and more electric vehicles cross the 200,000-mile mark and beyond, it's becoming increasingly clear that electric vehicles are here to stay.
