September 2012: American Suzuki

That is all the problems with Nissan Leaf current generation and Tesla where you have no insulation or proper management of the battery pack. Those auto companies that have gone 800V have done their work that it is not the issue it is stated to be.

What's even more ridiculous is that you basically need a climate controlled garage to really keep your battery in proper condition. So if I bought an EV without a garage, it will degrade faster than having a garage. It's a shame people buy EVs and then drive to work and park their cars OUTSITE...🙄 "Hot climates also increase battery degradation, so keep your EV in the shade if possible, especially when charging it."

So you're telling me your Escalade is making around 220hp now?!? Or would you say it feels just about as strong as it did when you first bought it? I would bet a good amount that it's making around 90% of it's original power numbers.  And one great thing about ICE is that they aren't getting worse year over year for just sitting or hardly getting used. Your article states that a battery will degrade year over year regardless of it being used or not. 

20yr old ICE is not making 90% of its hp/torque, those rings, transmission, gaskets, etc.  and the overall condition would have it much less than that. Most engines are having to be rebuilt by 250k miles. Yes there are exceptions of those that are well taken care of and last a million miles,l but even then, they are not producing 90% of their HP and Torque and gas mileage is not what it was new either. Modeling of batteries is much beter than 64% also, We will have to take a wait and see attitude as electric motors have kept their output far longer than ICE motors as they age.  I think it will come down to maintenance, garage kept versus sitting outside in the elements. Lots to be taken into account.

No, that is not the headline.  "EV Batteries Can Easily Outlast A Typical Gas Car’s Lifespan: Study" What you said and what the article is about are two different things. A car's lifespan is almost always down to getting wrecked and totaled.  "Over this generous timespan, EV batteries suffer from about 1.8% degradation per year. This means that you’ll lose 1.8% of the original range every year–not ideal, but certainly not a dealbreaker. After 20 years, if nothing goes catastrophically wrong, you can still enjoy 64% of an EV’s original range. The data comes from analyzing over 10,000 EVs."  Oh wow, 64% battery capacity after 20 years? That makes most any EV pretty much done by 20 years. Nobody is buying an EV9 with 150 miles of range, and decreasing by the year. A 20 year old ICE vehicle still is making 90% of its total output and range.
