In reality they don’t have one big battery. Their big battery is a battery of batteries very similar in form to the ones you put on your toys. All those batteries need to work on unison, and need to have the most similar voltage, capacity and charge discharge cycles. If you could swap those individual cells you would create as many problems as you solve. And accessing them would be difficult because those packs are cramped between sandwiches of cooling layers. But hey, loading your car with batteries like bullets into an A10 plane ammo belt would be cool as F

Reply to ELI5: How does "acquired taste" work? And how are some tastes able to be acquired no problem, while others will never be acquired? by PuzzleBrain20
Friends and family who are educated, employed or experienced with child development and kids in general have said it takes 7 to 10 tries to get a youngster to start eating something new. That's got to translate to adults. Except we don't have someone urging us to just have three more bites of tuna casserole or broccoli and cheese.

From the word itself, acquired meaning you've exposed your taste to that food many times, you've grown used to it. I remember not liking coffee that much in the beginning, but overtime I try to tweak it a bit and add something I like to the coffee to make is taste bearable for me like more sugar or cream. Eventually my taste got used to it that I started adding less sugar and cream.

Maybe loss of efficiency with added resistance between multiple batteries and systems? Idk???

That is actually what is happening in some cases with smaller vehicles.
Gogoro who make electric scooter in Taiwan, have a system where instead of charging your scooter at a charging station you swap out the batteries with fully charged ones.
This is possible because these scooters only need two batteries and they are small enough to be liften by a single person without tools or help.
For cars that would not work as well.
Replacing batteries when they can no longer hold a charge in parts would not be too much of a benefit since they would all wear out at about the same rate and it makes more sense to do it all at once rather than come back to the shop every few weeks or months.
Since the batteries are so massive and cars move very fast, making them easier to remove would have some safety effects.
In general EV batteries only need to be swapped out after several years and it needs to be done by a professional and the fact that that professional takes a bit longer is a trade of for the battery staying put where it most of the rest of the time.

Because people that are going through a separation are often completely unreasonable and simply want to hurt the other person.
In the end, all they do is to cost themselves far more in lawyer fees than if they’d just been reasonable in the first place.

The big batteries are already made up of smaller batteries internally.

Uranium. Element 92.
Since it is quite radioactive it is primarily used for nuclear fuel or nuclear weapons. Uranium isotopes with less radioctivity is used for bullets & armor. Formerly used in the glass industry to make green/yellow tinted glass

It’s a conscious choice.
Battery swap technologies for electric vehicles existed in the freaking 1890s in Manhattan. China is incentivizing battery swap vehicles now.
Car makers are choosing to not battery swap for $reasons, despite that it would be better four everyone if all that was needed to “recharge” was a 5min visit to an automated garage that swapped batteries.

My answer also explains why you can use copied disks with genuine hardware.. because someone figured out the key.

This is a great answer for digital protection. Physical piracy would be where you physically need the game disk to play the game. But physical disks can still be copied. Either to another disk, or to a hard drive.

These huge batteries are made of smaller batteries. Making them modular would make them heavier, bulkier, and possibly more dangerous since at any one point someone could tamper with them and do something wrong and cause a huge fire risk, whereas sealed batteries can have more compact wiring and are considered bad and in need of replacement if there's any damage to them. That might seem wasteful but the fire hazard is big.

According to Google, if you replace the battery with AA batteries, you'd need 25,000+ batteries... that'll take some time to replace... also the more batteries you have, the more potential failure points you have

More often than not, they DO have a lot of smaller batteries that can be swapped out based on need.
It's just that, eh, the batteries are a safety hazard for rescue services when the cars are in accidents, and to make them less of a hazard they are combined into a large container that is comparably good at confining the hazard.
There are other reasons to, such as thermal control of the batteries and weight distribution concerns.

Reply to ELI5: What are the consequences of overeating? by Smart-Veterinarian11
A wolf can eat as much as it can and go on hunting the next prey. The day it is too fat to catch the prey he will skip the lunch, and this keeps a wolf as fat as possible while being always fit enough to hunt.
If you take that wolf and give it unlimited food it will eat until it dies.
You are the same. Problems are:
1 your heart can’t pump blood to feed the gigantic muscles you need to move your fat around. Your heart will soon or later collapse for fatigue.
2 fat piles up in your blood too, and can clog your arteries. This can give enormous pain when a clogged artery stops feeding some tissue, and that tissue dies. But this can happen to organs too. It can happen to your brain or heart with fatal results.
3 kidney & liver are sized to keep your body clean, if you increase your body size too much they won’t keep up properly. Long term diseases will come.
4 you rot. Yea your tissue needs blood to live and if you are fat enough to not move enough, some parts will simply be compressed onto the sofa, receive too little blood, die and rot. Skin is one of the most likely early part that will die and rot.
5 you can’t run. There may be a fire or some other hazard and you can’t simply escape.
6 good news, fat floats better than bones so you won’t drawn easily at least. Also you can resist cold a bit longer.
