They were possibly confusing nitrogen with carbon dioxide. CO2 will definitely lead to distress in high concentrations, and has been used in some slaughterhouses.

What's the charging efficiency?

Most electric cars only have 1 gear and it's always engaged. If you put the car in reverse, it uses the same gear, but the motor spins the other way.

Even in neutral the motor still spins when the wheels are turned, it just doesn't output any power to the wheels.

She looks very polite.

There is a difference between climate concern, where you desperately want to do anything to fix the climate problems, and climate anxiety, where you are so overwhelmed by the climate issues that it interferes with your ability to take any action.

I suspect this study is focusing only on the latter.

Most Russian people have committed no crime, and many do not support what their leader has done. We should not condem people for the country they were born in.

I have used Kagi for several weeks and can't go back. I can finally find things on the internet again and I don't want to lose that again.

If you don't mind paying to use a search engine, Kagi is actually pretty good. Not as good as Google was 20 years ago, but significantly better than any other search engine I can find today.

Interesting extension. I think I'll give it a try.

It is entirely open source, and the website does a very good job explaining what it does and why.

It depends on a lot of factors including the battery chemistry.

NMC (Lithium ion) batteries are common in high performance cars and older EVs. They should be kept between 20% and 80% charge for normal use. 60% is ideal for storage, but anywhere in that range will do.

LFP (Lithium ion) batteries are common in cheaper and newer EVs. They don't have a problem with being stored at 100%, and do have issues with not being regularly charged to 100% (monitoring gets less accurate over time until fully charged again), so leaving it at 100% is fine.

Lead acid (particularly calcium) batteries get damaged when discharged too much, so it's fairly important to keep them topped up. If you are leaving the car for a long time, it could be worthwhile to connect a trickle charger to the 12V battery to prevent the car's computer from gradually draining the battery. Some cars will top up the 12V battery from the high voltage battery if left for a while, so this may not be needed.

While I have little experience with low temperatures, I suspect that the car will be fine if left as stated above. The battery shouldn't get damaged by low temperature storage, and shouldn't lose much charge over time. Just don't expect full performance immediately after returning to it.

Be aware that an underpowered or stuck stepper motor can "skip", causing the position data to be incorrect.

A servo motor has active feedback, so doesn't have this issue. Servos do have their own drawbacks too, so they are not always a suitable replacement.
