I can see us getting to a point where there will be a handful of standard battery sizes (just like AA, AAA etc.), with all of their ports in the same location. If it’s relatively easy to swap out batteries, someone may choose to go with the cheaper battery to start with (and a shorter driving range) and swap out for a more efficient battery when the technology improves.
Used car batteries with say, 80% left of capacity, will have many other applications.
All that said, I find the “20-year Life” claim most intriguing and, since we have no data, most speculative.
One of the other concerns about batteries is that they have to be replaced eventually. My son’s Prius is over 200K. I think the previous owner (Bro-in-Law) replaced the hybrid battery.
20 years is a pretty bold claim. Put a warranty on it without all the bullshit caveats, and we’ll discuss.
Samsung is the battery maker, they will sell to car companies.
Or, are they auctioning off their tech to the highest bidders, and the rest can suck eggs?
My main hope is they make the batteries, and the car companies must make cars compatible to them, and not the other way around. Issue sis that car companies want their batteries in a certain place on the car, and that place differs, even slightly, among car makers.
They should be as compatible, standardized, if you like, as the 12V’s in cars.
They are most likely providing testing samples to a variety of automakers, who will decide if they offer superior value before buying and incorporating into a vehicle.
Are they solid state?
Are they manufactured by child slave labor?
We have no data doesn’t mean Samsung doesn’t have any data. Presumably they’ve done some time to failure modeling/analysis to come up with this number
They also do not have data. They have an estimator based on assumptions, and it would be nice to know how that comes up with 20 years. I mean, we’re actuaries. We know how difficult it is to predict the future.
Don’t need it, though. A warranty is all I need.
Fair enough. It’s your decision to buy or not but a particular car.
When I took the drive with my sister’s EV, we had a 15 minute stop. I think we were using level 3 chargers and she was saying there are now starting to be some level 4 chargers. 3 or 4 years seems to be a long time for EV related stuff. I’m guessing there’s plenty of time for the number of higher speed chargers to be built to increase.
So if you design an ICE engine, build it and put on the dynamometer, you don’t have any data before you put it in a vehicle? Sometimes you prove yourself to be one heck of an actuary for an engineer.
Presumably by looking at the failure rate of whatever it is that fails in their batteries.
Also, in the lab environment, you’re able to push a battery through charge cycles far faster than what people would be doing in normal life. They’ve probably been able to run the batteries through the equivalent of 20 years of normal use in a period of a few years.
Eh, I’m a so-so actuary who understands limitations, and who knows how to write disclaimers.
You typically see reports in terms of cycles, not time. At one point in time I thought all % decrease was cumulative, but that might not be the case. In testing they will specify the SOC change used for a cycle, and probably use a standard range.
Angela Chao wouldn’t have drowned if she had been driving a yangwang u8 instead
Mamasmurf and I haven’t been able to reach a compromise on vehicles. I want small and electric/plug-in. She wants a minivan or 3-row SUV since her family flies into town frequently and we’ve had to rent or borrow so they can all fit. So… we’ve just been driving the 2010 corolla which is fine for everyday use, but not great for longer trips or hauling big stuff. My compromise was a Rav-4 prime or model Y, but mama doesn’t think either are big enough.
My Dad just told me he’s planning to get something new and will give us his 2014 CRV. It isn’t either of our ideal solution, but will immediately be more practical for hauling stuff / road trips and having a 2nd vehicle for when people visit. Still have my eye on the EV9. Hard to drop 70k+ on a new vehicle that the kids (age 1 and 2) will demolish.
I’ve spoken to a few owners when I’ve seen them at charging stations and they’re happy with them. Still early days though. A good-looking vehicle.
I was speaking to my mechanic today. His claim, EV’s are going away. He said ford even shuttered it’s production line of the ev 150.
He said hydrogen is the future.
I dunno man.
Maybe he’s talking distant future.
Hydrogen might work if a trick could come by to each house and fill a tank.
Oh, and make them idiotproof, cuz Hindenburg.
