Overview:
Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

Just because BYD and CATL have historically been the best, it does not mean they they always will be. So everytime they release a new battery, it is completely reasonable to question if its actually as good as they claim. You seem happy to take it at face value, I am not. If there truely is no degradation to the batteries longevity, why wouldnt BYD actually publish that?

A car that has 400 km range which is normal today, would than have a battery lifespan of 1.2 - 2.0 million km.
Corrected for degradation 1.08 - 1.80 million km!!!
EOL is usually considered to be 75-80% capacity. So you could probably use it for years beyond that.
Not historically, they are currently the best.
Absolutely, but were the same questions asked when Tesla announced their latest super charger?
Here BYD was ridiculed as being trash, despite they are probably #1 or 2 world leader on car batteries and charging together with CATL.
I've read 5 articles about it now, and none question the durability of the battery, probably because there is no reason to.
Of course fast charging degrade relatively more than slower charging, that's the same for Tesla cars too and all other brands. The point is that these are designed to actually handle the higher charge, so you can actually use it.
But if you use fast charging every day, there will be a noticeable difference for every EV.
I never claimed they broke the laws of physics. Just that these will most likely be exactly as durable as what is currently available.
