Sorry, why is it not spread out? Every cell has ESR. What is not uniform?

There are different lithium ion batteries. The internal resistance graph is for LiFePO4 which is a less often used battery type I believe. The curves will not be the same for the cobalt nickle batteries more often used. I'm not sure they all have the same curve for wear over temperature which is the curve with no description. -- Rick C. --+- Get 1,000 miles of free Supercharging --+- Tesla referral code - https://ts.la/richard11209

You seem to be thinking the heat is not internal, but external, like sitting in the hot sun. Or I'm completely not understanding what you are saying. The heat generated from using the battery will be from every cell. So every cell has the same thermal time constant and very well matched temperatures. It would be externally supplied heat that might be less uniform. What am I not getting? -- Rick C. --++ Get 1,000 miles of free Supercharging --++ Tesla referral code - https://ts.la/richard11209

The cells at the centre of the battery pack have longer thermal time constant than the cells at the surface - they have a higher thermal resistance to ambient, even if the heat capacity of each cell (temperature rise per joule dissipated) is the same (which it ought to be). The cells in the centre of the battery will get hotter than the cells on the surface. Since this will lower their ESR it makes the whole calculation even more complicated, because they won't be dissipating as much heat once the core of the battery has warmed up. -- Bil Sloman, Sydney

Ambient??? What ambient??? These cell are all cooled/heated by water flowing past them. Ambient has very little to do with this when driving the car. Oh, and the "center" of the pack is of little consequence, since all the cells are adjacent to "ambient" at the ends since they are only stacked one high. They cool or warm all night, so by morning they are pretty uniform. They are heated INTERNALLY from the current flowing through them in use. Each cell receives the same amount of heat from use. There is very little, if any, gradient of temperature.

No, the cells in the center of the pack do not get hotter. If there is significant temperature differences, the battery pack gets unbalanced and it impacts the performance and life of the cells. There is virtually no extra cooling/heating at the periphery compared to the cooling/heating from the water flowing through the battery pack. Tesla did a great job designing their batteries and this is an important aspect they did a great job on. Oddly enough, it's the UI they seem to have whacked. -- Rick C. -+-- Get 1,000 miles of free Supercharging -+-- Tesla referral code - https://ts.la/richard11209

Perhaps you are not aware that we typically start with no rules. Then we have problems and create rules to deal with them. So now we have driver's licenses that you must qualify for, rules of driving, rules of commercial driving where you are piloting 40 tons of vehicle at 65 mph. Someone, somewhere thinks it is a good idea for the drivers to be adequately rested. Then there's you.
And the rules create more problems than they solve. People are not animals, they don't need to be monitored and controlled like children. 99% of us are perfectly moral folk who wouldn't cause harm. Don't you trust yourself to behave?

That's where you are wrong. Everyone breaks the rules even with the threat of punishment. We weight the cost and the likelihood of getting caught against the benefits of getting away with an act and behave appropriately. I am quite certain that if we did away with speed limits, there would be much worse behavior on the roads and many more accidents and deaths. The rules may create problems, but most people feel requiring truckers to take appropriate rest breaks is better than seeing more people die on the highways. Heck, even factory workers get mandatory breaks by law. Without laws requiring some level of consideration of the workers, we would still have the sweatshops and child labor conditions of a hundred years ago. BTW, people *are* animals and mostly do need to be treated as such. I guess you didn't pass biology, eh? The fact that you are not aware of any of this, speaks volumes about your judgement. -- Rick C. -+-+ Get 1,000 miles of free Supercharging -+-+ Tesla referral code - https://ts.la/richard11209

Bullshit. I ignore the speed limits unless I think there's a camera or cop around. If there was no speed limit, I wouldn't waste brain power checking and would concentrate on the road more. And it's been shown by a government study that only 4% of accidents are caused by speeding. But for some reason people like you think speeding is a bad thing.

No, you shouldn't assume someone will crash without a rest break. You should get him in trouble if he crashes, for whatever reason. What if the rest break involves him playing football? I bet that's not on the tachograph.
> Heck, even factory workers get mandatory breaks by law. Without laws requiring some level of consideration of the workers, we would still have the sweatshops and child labor conditions of a hundred years ago.
If I want to work in a sweatshop I should be allowed to do so. If I don't like the conditions, I'm free to leave. I'm not chained up am I?

And for some reason, people like you fail to understand that is WITH laws. Without laws about speeding the numbers would be much worse. But it doesn't surprise me you think this way. If nothing, you are consistent.
> You also don't understand Libertarianism, it's not a free for all you can murder folk, it's about removing rules from things where we don't need them.
You had not mentioned Libertarianism until now. Why did you bring it up? I've not been discussing it.

Unfortunately, once they have the crash and kill someone, it's too late. Laws are to prevent harm. Enforcement is too late, but the threat of enforcement is what gives the laws an impact. Otherwise they are just recommendations. A trucker doesn't need to sleep after driving for the max time. He just has to stop driving and do something else. Talking about playing football is just being silly, but again, consistent for you. They don't assume anyone will crash without a break. They *know* it will happen to some, too many. Those laws were passed and are enforced to prevent history from repeating.

If you wish to work in a sweat shop, please do so. It will need to be in another country to be legal, but I'm ok with you leaving here. But, again, you think everything is about you. There are plenty of people who don't want to work in those conditions. If they are legal, it will be hard to find better work. So others *won't* have a choice.

LOL! Nearly everything you say is emotion. It has been shown time and time again that humans are bags of emotion tied up with little, tiny strings of thought. That's why so many were manipulated by Trmp.

People speed if they want to, the ones that stick to the limit do so because they think it's the right thing to do, not because it's the law. And think about my 4% again. Do you know hoe many people speed? Again, a government stat - a third. So even if everyone sped, that would make it 12% of accidents caused by speeding, the rest by morons doing something stupid.

Stop being such a pansy. This way would work far batter - instead of getting an insurance premium rise when you cause a crash, no matter how minor, get points on your license. X number of crashes and you're off.
> A trucker doesn't need to sleep after driving for the max time. He just has to stop driving and do something else. Talking about playing football is just being silly, but again, consistent for you.
You really are stupid, do you seriously think using your brain for something else is a rest?!
> They don't assume anyone will crash without a break. They *know* it will happen to some, too many. Those laws were passed and are enforced to prevent history from repeating.
They assume because it happens to some it happens to all. I might crash because I didn't get any sleep last night, well before my break time. Only taking account of driving time is insanity.

I never said they had to did I?

If you're good enough to get better work, you do so. If you're not good enough, it's better to work in a sweat shop than be unemployed.

No it hasn't. Compare us to animals as I suggested.

Wow, completely backwards train of thought on your part. The emotional ones are the lefties. Those who think with logic are right wing. You're the touchy feely type that think it's ok to steal my taxes to pay for your problems.

Are you fucking stupid or what? All I said here is you're saying the same thing twice, therefore there's no point in me answering it again. That is all, stop reading anything else into it.
