Lithium Ion submarine batteries, just seems like a bad idea from the get go.
I’ve seen what they can do to a cell phone. I can only imaging what they’d do in a submarine.
So how many AA batteries does it take to power a submarine?
As long as the battery doesn’t break, like a laptop battery should not break open. They should be okay. I mean really, our navy has submarines powered by a nuclear reactor. Did you think about that?!!! I wonder what recharge mechanism the submarines have.
Diesel? Noisy?
I kinda like it. IF they can make it work, I bet its gonna be red October-level quiet
Feeling you on the cell phones, however.
Yes noisy on the surface but they can stay down a long time. These are not your GF diesel boats.
Solar.
Sounds like an underwater kamikazi mission to me. Li ion batteries are too volatile and explode way too easily.
Technically, I think they’ll be using 18650 batteries, just like the Tesla. It is the same shape as a AA, but larger.
My vaporizer and flashlights use that size. They rock.
No worse than a lead-acid battery getting sea water in it.
If you’re getting seawater in your battery compartment you’re in a world of hurt anyway, and the type of battery probably doesn’t matter much.
“If you’re getting seawater in your battery compartment you’re in a world of hurt anyway, and the type of battery probably doesn’t matter much.”
I am going to hypothesize that they are in sponsons outside the sub’s air compartment and that they are in nearly indestructible individual cases. I wonder what effect a nearby explosion would have on them. Also, if they are small and hooked together each connection becomes an additional point of failure. As to charging them either a nuclear battery (a type of dry-cell except it generates charge) or a fuel cell would do a nice job.
They’re using diesels to charge. These are straight-up diesel-electric boats with a new battery technology, by my reading of this.
“They’re using diesels to charge.”
You know, I thought that can’t be right because they are usually at the top of the technology game. I can see having a diesel as a backup. (It’s a rare article where the reporter gets it mostly right.)
On the other hand, having been in the military industrial complex for thirty years, I have seen a lot of resistance to even proven newer technology.
The Japanese have the best conventional subs in the world, but snorkeling while recharging batteries is revolutionary?
The Kriegsmarine might want to discuss that with the Japanese MSDF.
OK, that’s funny right there!
I think what’s revolutionary is the quick charging of the LI batteries, such that you’re at the surface / snorkeling with the diesels running for a much shorter period than with longer-charging-cycle lead-acid batteries.
