Comment on Why Toyota Is Intentionally "Falling Behind" On EVs | Morning Brew (10:10)
aleph@lemm.ee 5 months agoHybrid engines have been around for quite some time, though, and they can be just as reliable as ICEs.
On the other hand, the weakness of EVs right now isn’t just the charging infrastructure - it’s the batteries. They’re big, heavy, and very expensive to replace. This is especially true given all the new electric pickups/SUVs coming onto the market in the US. Battery tech needs to mature a while longer, IMO.

What the hell are you doing that you need to replace the battery enough for it to be classed as a weakness for all EVs??
Look up Lithium Iron phosphate batteries. They will outlive the car they’re in even better than the lithium ion ones that are the majority at the moment. Those lithium ion batteries will also outlive the vehicle they’re in btw. The only ones that won’t are Leaf batteries because either they’re an old chemistry or because nissan cheaper out and didn’t put a coolant loop in them.

It’s not so much of a problem for brand new modela but there are still many older ones that suffer from battery failure and degradation outside of warranty.

Do all cars use LiFePO4? I thought most used Lithium Cobalt Oxide because it has a higher energy density, that’s what’s used in smartphones and laptops. Using LiFePO4 means reducing range and increasing weight. Ditto for Sodium Ion batteries.
All Lithium Cobalt batteries need replacing after about 8 years of regular usage. That’s not great given we still see 20 year old cars in use. I guess there are steps you can take to reduce this, like not charging to 100%, but they all fail sooner or later. All this rapid charging stuff doesn’t exactly help either.
You’re going to have to come up with some serious evidence if you want to say car batteries are not a problem for current gen EVs. Maybe with better Sodium Ion tech they can be extended in lifespan and reduced in cost enough to be practical for most people, but it’s still going to require infrastructure overhaul and won’t be applicable everywhere.

No, I’m not going to have to come up with serious evidence because it’s been all over the place for quite a few years. It’s not new that the batteries in current a recent gen EVs will easily outlast the car. Sure, early and probably current Leafs are crap but even they can last quite well. Tesla? Easy piss.

Thanks for playing.
Sorry but I’m not going to be more thorough because I’ve had this conversation plenty and your statement that a battery needs replaced after 8 years is one of those classic giveaways for people who don’t actually look into any of this but rather just read the usual FUD and click bait. Go look up everything electric, read and watch their content for a good start.
