Electronics manufactures must from Saturday fit all devices sold in the EU with USB-C charger ports in a bid by the 27-nation bloc to reduce waste and cut costs for consumers, who will no longer have…
Yes and no. No need to hot swap massive EV batteries. Rapid is fast enough. But yes so the EV can be upgraded. The batteries go obsolete quicker than they degrade. So make it so we can swap the batteries and keep the rest running. In fact, just right-to-repair the whole car. In fact, the whole everything!
The batteries don’t live in isolation. There are other pieces that are dependent, whether for basic function or for calibration.
Example: Chevy issued a recall for mislabeling some Bolts as N2.1 vs N2.2. The fix is a sharpie to fix the label, and “reprogramming the Hybrid Powertrain Control Module 2”. I could find no information on either of these chemistries. Dropping in a LiFePO4 would require at least the same, and possibly more.
Now, if you’re suggesting simply swapping a matching replacement part (obsolete as it might be), then I’m on board with that
But the economics is much harder if batteties aren’t unique to each EV. (They aren’t completely of course, the guts of my E-Berlingo are shared across a number of others.) EVs, like a lot else, should be designed with maintaining and upgrading in mind. Especially with parts like batteries which are in such evolutionary flux.
This sounds great until you’ve had to repair an old car.
Everything rusts, warps, etc. The same things that make it hard to change your brakes will make it hard to change the battery pack, and you’re expecting a robot to do it for you (and fast!).
There were companies built on this idea. I think they’ve all gone under at this point.
They have gas stations in the middle of nowhere as long as there’s enough people with cars. Not saying swappable battery facilities aren’t more difficult than gas station infrastructure, but range matters a whole lot less when you can swap a battery in under five minutes.
That is something that I wish would come true. This would also open EVs to the industry in some new ways. Currently it kinda sucks if you have machines that have to be able to run the whole day without big interruptions. When you’re able to just swap the batteries in like 5 Minutes this machines don’t have to rely on fossil fuels that much and are open to be replaced by electric ones.
What I’m thinking about are machines like tractors for farming. During the summer it happens that they are running for 8+ hours without interruptions. Building a battery this big will be quite challengening. However, if you’re able to swap out the batteries after like 2 hours and then continue with work you effectively solved one of the biggest problems with not that much of a hassle.
One of the benefits of EVs is we can get rid of a lot of infrastructure. Everywhere already has electrical so home and destination chargers are a minor add on and it’s only superchargers that are new infrastructure. Meanwhile the entire gasoline and oil refining, distribution, and tens of thousands of gas stations can just go away, along with their associated pollution.
Swappable batteries may sound cool but they’re less edficient plus now we have to build up a huge new set of infrastructure agai, we have to standardize batteries, and we can’t build them into structural parts. The only real advantage is speed but that’s not much advantage if you need to drive somewhere. I’ve never had to charge more than 25 minutes at a supercharger, so swapping a battery is only convenient if it’s at most ten minutes more away. Then you’re also assuming there will be more more battery and charger advances, such as those solid state batteries that a couple vendors claim are already in production, such as 800v charging that a few vehicles already can do, such as the latest Superchsrgers that can charge faster than any car can accept so far, or the semi chargers that have a few built out.
Long before you could build out a huge new infrastructure for seappable batteries and standardize cars around it, we’ll already have charging improvements that will make seappables irrelevant. You could argue they already are irrelevant in some areas
While 25 mins doesn’t sound terrible you have to consider throughput. Long lines, waiting for chargers could become an issue if adoption takes off, and if I ever drove by a set of chargers that was full up and more people waiting that’d probably put me off from buying one.
Including cars.
Drive in, swap non-proprietary batteries with an autoloader, drive out. Done.

Oh totally, I have a E-Berlingo which basically an ICE converted to an EV, so there is all kind of compromises.
But batteries do improve and an old existing EV can be improved battery. Example: https://evsenhanced.com/aftermarket-battery/

And range just dropped by half. Going somewhere without a loader? Have fun charging way more often.
Would still be nice for road trips in the civilized world though.
