Why do people complain about MSFT when Sony and Nintendo are way worse in this regard? I hope they first split all studios among themselves so that EU can have enough ammo to break them all up or regulate cross platform compatibility in some other way. I'm ok with having every game 20% less performant on secondary platforms
I’m sure this is not what the poster meant, but in fact most EVs and hybrids use multiple battery technologies in parallel. For example, a Chevy Bolt has a lithium ion battery to power the drivetrain and a conventional lead-acid battery for the accessories. My old Prius had a NiMH battery for the drivetrain and a lead-acid battery for accessories.
A lead acid battery is just a holdover from the way every car used to have one for the accessories, and unless you want to redesign all the accessories, it's easier to have a 12v-14v circuit just for that.
And before you say "oh, but they could just use a voltage converter from the high voltage battery", they need to consider that some accessories use hundreds of amps briefly (eg. the power steering - that makes for an expensive voltage converter), and the car still needs to operate lights and stuff while the high voltage battery is offline (eg. after an isolation fault).
For all of the above reasons, the lead acid battery is still there, even though a clean sheet design would never have one.
My Hyundai Ioniq hybrid has a 12v section of the Li-ion battery that can be charged off of the hybrid battery while the car is off with the press of a button so that the car never needs to be jump-started unless the entire hybrid battery is dead.

This seems like an odd choice - unless you already bought a supply of lead-acid batteries for the next 50 years or so.
I've read about a car using supercapacitors in the regenerative brakes to capture energy at high current and, then let it trickle back into the main batteries (or drivetrain) at levels that won't damage it.
That was a bit of a necessity. Users wouldn’t want their clock to reset when they swapped batteries, and you couldn’t be sure the machine was connected to a time server to set the time at boot.
It could be great if you were a car manufacturer that already had an existing, very large supply chain for lights, dashboard, powered window motors, and other accessories, that were already 12 volt.
Tesla switched from lead-acid to 12V lithium ion their S and X models in 2021. James May had some issues with his Tesla when the 12V battery went flat.
This was the best news I heard at Tesla investor day. It should simplify and cut the cost of the in-cabin wiring.
When Sandy Munro interviewed Elon Musk a couple of years ago he said "Why are you still using 12v stuff in the cabin?"
Musk's answer was that the automotive supply chain was entirely geared around 12v equipment and they had to take advantage of that to get to market quickly.
The supercaps aren't for long-term storage - just long enough to allow the extra juice to flow back to the batteries. Racing cars sometimes do that with flywheels.
As for 12V, all one needs is a regulator. Unless you have a long-term supply contract (that, I bet, won't be renewed for too long), a lead-acid battery is just dead weight.
I don't think that is what this person is talking about. Yes having an extra lower voltage battery is totally normal and every EV either has a led acid or an additional smaller LiIon battery.
Having multiple chemistries in one battery pack is of course possible, but I don't any car who is actually doing that.
How come it is hard to find leaks like these on popular torrent websites? I would expect it is very fast going from finding code like this to creating a torrent? Are these torrent websites legitimately scared of having content like this?
The people who follow this stuff already know exactly where to look. Why bother with a torrent when there are direct links on countless grey-hat and opsec forums already.
How about this. Let's say historically 200 square meter houses costed 200k€ to build. But not enough people can afford that. Then you make a project where you count in the cost of materials but cut down cost of labor, price the house at 150k€ and say that there is a shortage of labor because you cannot find someone to build the house for the money you have available. You can even be realistic when saying that if you increased the price of the house you couldn't sell it. Maybe there just isn't enough people willing to pay for the house for the cost other people would be willing to build it for. Even if you managed to find people to work for the reduced pay you can just create a cheaper project and cut down on labor cost even more because now you sold to all the people who were willing to buy for 150k€. The "labor shortage" is basically guaranteed for any industry all the time. All it takes is for you to create a project fitting lower on the demand curve and cut down on labor since you can't really reduce price of materials.
Everyone was pushed into aerospace? Sounds like a small industry for everyone to be pushed into. Maybe it's a city with an aerospace company or something
