Over at Forbes.com there’s an interesting article by Bill Roberson concerning the life of their cars’ batteries:
The article is quite timely: Some of the first production Tesla vehicles were released in 2012, ie 7 years ago, and the company’s warranty period is for 8 years meaning that some of the oldest Teslas out there are about to go out of warranty.
At the risk of giving most of the article away, the author discovered the batteries in those older Teslas appear to still be in remarkably good condition, degrading in some cases only some 10% at most in terms of their distance/range.
A nice thing to realize!
One thing I would note regarding this article and electric cars in general: We’re still in the very early days of the electric car “revolution” (if you want to call it that) and, as noted, some of the older Tesla vehicles are only 7 or so years old.
The battery life has already improved. My Model 3 is a “long range” vehicle that, in theory and when charged to 100%, is supposed to have a range of 310 miles. Now, to be clear, the range depends on several factors, including how fast/slow you’re driving, using AC or the heater, etc. etc. The new Model S cars, however, have a range of 377 miles, an astonishing increase compared to previous models.
Again, we’re at the beginning of the electric car revolution and I strongly suspect in time we will see better and better batteries and better and better battery life.
Within the article there is talk of newer battery modules which may give these cars a range of 1000 miles and charging which will be as quick as getting gas in your car is now.
Frankly, it wouldn’t surprise me at all.
But it is encouraging to see that the Tesla vehicles are showing such durability regarding their batteries.
It can only get better with time!
