EV Battery Longevity

This cluster focuses on debates about the lifespan, degradation rates, replacement costs, and real-world performance of electric vehicle batteries, often comparing them to ICE vehicles and citing examples from Tesla and Nissan Leaf.

The battery's "limited lifetime" is currently longer than the expected lifespan of the car. The vast majority of EV batteries are still in "first use" and that is including more than a decade of Nissan Leafs (the model with the worst issues of battery "degradation" known to the used market). People are still driving the first and only battery of the car into a car's second decade (and likely will into its third, but it is too soon to tell). Statistically s

Modern batteries can last a long while though. If you take care of it and mostly keep it between 25-75% and don't supercharge it too often. There are Teslas with more than 300K miles on the original battery.I have a model 3 with ~80K kilometers and the battery is as good as new. 2018 model. For someone that drives 10-15K km a year there's maybe 30 years more driving on this battery (400K km).My previous ICE car had two head gasket replacements in the 10 years I owned it. I also

People have put 300k miles on their EVs already. Batteries already outlast the car.

The average car today lasts 12 years, or 200,000 miles, with 300,000 miles possible with luck and good maintenance. Modern EV batteries are designed to last longer than that. Moreover, EV battery capacity loss is nonlinear: most (I've read 80%) of the eventual loss happens in the first couple years.So if you're looking for a car with the least amount of battery degradation between purchase and EOL, buying a used EV rather than new is actually the better decision.

EV battery is degrading over time - a replacement costs ... between 5000-20.000$ [1]. I am not sure that we have objective data on the scale of this issue.[1] https://www.cars.com/articles/how-much-do-electric-car-batte...

This is true, and EVs have not been in the market long enough to really know how they behave over long periods of time and high miles. There is also not a strong enough secondary market of mechanics, parts dealers, second-hand parts, generic batteries/drive units etc.BUT, having said that, the common sentiment that I'm picking up in my online "research" is that it's not as a big issue as made out to be.The Nissan Leaf specifically has issues with its battery design

I think it is price. Here I see cars with batteries that last well enough for 10+ years, and I'm confident that the price will drop over time if I keep one long enough to actually want to replace it. Along with all the other parts that wear out. Over here I think new car buyers won't tend to drive their cars into the ground, with cars on the road after 20 years generally having been purchased second hand. I don't know how the second hand market or resale value of EVs will look.

From your own link:> In general, you can expect the lifespan of an EV's battery pack to be at least 10 years or 100,000 miles. Most will go much longer and further if you treat them right.So I get what you're saying but when you're going to drive a car that will spend most of its life under your care at >100k miles the calculus gets a little different. And I really get the impression on HN that people are just unaware of how many people are driving old high mileage car

FUD about battery life and having to spend over $10k to replace one was a large factor in EV depreciation. Some people assumed car battery life was like that of a cell phone or a laptop, perhaps 3 years. There is increasing evidence that EV batteries with good battery management systems will last 15+ years (see https://www.geotab.com/blog/ev-battery-health/). Once the gen

Can somebody explain how are EV, and especially Tesla, batteries different from, say, my laptop batteries, which normally degrade to the point of being unusable within 4-5 years, and have to be replaced?
