Torque curves

Hi All,

Petrol heads keep on referring to the "torque curve" of an electric motor whenever the subject of a 'mechanical gearbox' comes up in conversations about electric vehicles:

The 'torque curve' of an electric motor is irrelevant to the design of an electrical system!
The starting point in the design of battery powered electrical system is the 'load current characteristic' of the system, which will comprise a 'spike' followed by a 'curve'.
A mechanical gearbox incorporated within the system, will provide an ever smoother 'load current characteristic' and therefore be much more efficient.

On board charging will reduce the weight of the battery bank and therefore provide much needed longevity (as well as preserving limited natural resources).

Coby, I'm not much of a fan of your mincing of words in your lame attempt to push your ideology.

Let's jump to the chase. Why should we abandon capitalism?

It doesn't keep them going for long, but nobody cares because they are all having so much fun setting light to each others' farts.

And you just explained why capitalists like Americans hate Norwegians. Understand what a finite resource is and manage it. When Russia slowed energy to Europe in 2021 it signaled its intentions.
You want our energy and we want Ukraine. With Russia, they could've shown how to adapt to their values/situation but failed to do so. When the former USSR ended it is because its leaders realized the world had changed.
And yet the West is still focused on the stock market while Russia had a very bad knee jerk reaction. What people fail to understand that being born is a life sentence.

Sounds like a load, of bullshit to me... Torque, is what gets the vehicle in motion, from a dead stop. This requires a huge load of current to be drawn. This needs to be addressed first. Your battery, wiring, control electronics need be able to safely provide that current, without burning up. The more weight you add to the vehicle, increase the amount of torque need to get it moving. Which should get interesting as more EVs hit the road. Not many people are aware of cargo capacity of their vehicles as it is. But, with an EV, it's going to be a significant detail. The motor and drive train will determine what's needed to safely deliver the current. Every time you start off from a dead-stop, you are going to draw a huge amount of current. How much is convert to motion, and how much is wasted from heating the wiring is important

The USSR folded because Reagan outspent them with intelligent arms instead of just bigger ones. Funny one would think that the Norwegians hate America, besides what is a Norwegian?

Liquid Hydrogen is -240 degrees centigrade, the North & South poles are only -50 to -100.

That means if we produce Hydrogen using surplus electricity from wind turbines located at the poles and then store it in those regions, we will be able to attract sea ice back to those regions and reverse (or address the problem of) rising sea levels.

Therefore; why waste hydrogen powering vehicles when we can get away with using batteries to power vehicles and use hydrogen for something more crucial to the future of mankind?

And now you have ITN thinking fellatio and phallic. Kind of
why he likes talking about such things. He should go get drunk
with lite beer. That's a code name for a banned forum member.
After all, a fallacy is merely wishful thinking which he keeps
talking about, right?

p.s., this is a research paper that can help me. The main issue is
I'm not a scientist.

Under such conditions, CH2O seems
to be a suitable candidate for testing the current understanding of
the methane oxidation process. Despite the relatively uncompli-
cated chemistry in the background troposphere, prior studies have
shown certain discrepancies between simulated and observed
CH2O concentrations. Some authors reported measured CH2O
concentrations significantly lower than predicted by models [Liu
et al., 1992; Zhou et al., 1996; Jacob et al., 1996], while others
came to the opposite conclusions [Ayers et al., 1997; Weller et
al., 2000]. The reasons for these discrepancies are not clear.

I'm the person who might have the answer. I've read a lot of research papers
and I have my core focus which goes back to the IPCC's 2013 report on climate change. I might be the person who teaches the IPCC what they don't know.
Yet their problem shouldn't be my problem. The primary issue might be that the leading scientists have no interest in science. The church has the same problem with its preachers.
