why joules

[fenderstrat]

I have looked around so forgive me if this has been posted I joined a week ago and everytime I start doing research on topics with this site I see 10 other interesting threads and get completely sidetracked from what I was looking for in the first place But anyway I have had my ipv3li for about 2 weeks now and cant seem to get a handle on this JOULES thing as far as knowing exactly what the power is.As far as the mod I just set it till I get a great vape and leave it.But from all my research it seems JOULES implies TIME in reference to work or power so if the vape hit is not timed how can JOULES be used as a measurement.

I gotta say again the ammount of info on this site is amazing

Joules is a bit hard to explain in detail into layman's terms. Yes it is a measure of time of work, when talking work in an electrical sense breaks down to watts and hertz. Our application it is watts per second, 40 Joules is equivalent to 40watts per second. Why Yihi went with Joules in their SX chipset boards where Evolv went with standard watts on their DNA chipset boards is mainly a marketing ploy. Hope that clarified things for you.

aaaahhhhhh,yes so JOULES sounds WAY more sophisticated and much cooler than just your plain old everyday WATTS..."MY mod runs JOULES".got it,THANKS

Of course, 1 joule is 1 amp pushed through 1 ohm for 1 second (do that for 60 minutes and it's a watt-hour). Or 1 kilogram-meter per second. Or a coulomb-volt.

So if you held down your button for 1 second exactly on a power setting of 1 joule, you will have expended 1 joule of energy, exactly. Or a watt-second. Or 1/3600 of a watt-hour. You can see that watt thing getting kind of sticky pretty fast.

The joule is a very handy energy measurement for shorter time periods and modest energy expenditures.

Undoubtedly, some engineer (who tend to be very exacting sorts of people) noted that the watt doesn't actually tell you very much and went with the joule instead. Is that watt setting per second? Per hour? Per century? It's technically undefined. With a joule, the time dimension is automatically included.

In practice, for vaping, watts = joules. We're used to our watts setting being watt-hours, just like we're used to a 60 watt light bulb expending 60 watts of energy in an hour, or 1 watt per minute.

I'd write it off as a peculiarity of energy definitions, realize it's effectively identical to watts, and accept that it's technically more accurate while being colloquially far more confusing. Or, typical engineer-speak!

W = J/s
J = W * s

Some manufactures just felt like joules better display what you are adjusting than watts. It really doesn't matter much. Nothing to be concerned about.

I'm not going to waste any time on the differences between watts and joules (the latter's definition often getting butchered) but for our purposes and as they are implemented on mods, there's absolutely zero difference between watts and joules. You're basically looking at a J instead of a W.

The whole reason for it? YiHi changing their approach/software/advertising just enough to make a patent dispute with Evolv a tougher case to fight in court.

Now that sounds like the REAL reason for using the term joules although if the e-cig community of manufacturers is anything like the RC heli companies in China its basically a legal free for all and patents are laughable

Nothing to see here ........ move along.

Evolve Decided to Patent vw.........
Funny, I thought my old Lionel Train transformer varied wattage to the engine......
Yihi decided best to not cross swords.

I doubt yihi could give a ... about evolv. The whole ecig business is a borrow and steal business so I sincerely doubt evolv would stand a chance in court anywhere but maybe in the US.
Its just nice for marketing. Sounds like something new. Proven concept; also often witnissed with mobile phones manufacturers etc. Give an existing technology a nice name when you put it in your mobile and all will think you're brilliant and inventive.

it's all about the math!

Joules to vaping is like this word problem....Timmy drives his car at 55mph, how far did he drive yesterday?

 

[Drinkmilk]

I think I had that question on my last physics final! Hilarious...you just made my day!

So does watts in a practical application. Proper terms would be watts per hour or watt hours.

Such as that your electric bill charges you by the kilo watt hour.

You asked why Joules. Here is what I was told by someone who works with Yihi pretty closely. Evolv had the first variable wattage device when they released the DNA12 before then it was variable voltage only. It was purely a marketing angle by Yihi to do something different than their #1 competition. I think that it was pretty cool that they did it that way, why not have your own board that does things a little different. For what we use the tech for the Joule is pretty much the same as the watt when we adjust the settings. You can look at it the same way I think, you can get more technical with all the data but for the majority they will not.

But they are NOT using the scientific term properly and it only creates confusion...bad move in my opinion

next up, kelvin for temp control..ha

 

[jimbodaddy74]

Why not joules?

 

[Drinkmilk]

Touché

Doubt it would ever effect someone knocking down a career at McD's flippin' Burgers
Or the Casual Vaper that can't figure out the difference between a Lithium and an IMR cell.

I do think that it could be highly refined using the Joule, but your right it is not the case at least not now.
