J/h is CJ/s is CWatts. That implies that battery factory converts materials and energy into power. That doesn't feel right. I think it converts those things into capacity which is a whole different set of equations. Maybe my example is not appropriate. I think I confused things when I equated...

Lets switch to joules and say that a battery hold 1J. A battery factory that churns out 20 batteries per hour is a 20 Jh facility. I think the area represents the total about of energy capacity generated by the factory since production began. That would be a useful figure when trying to work...

Thanks. I've had 2 responses from a question I posted just today. It looks like an active community. Happy to be here.

This is going to take some time to digest. Thanks for the pointer. Now I can't rest until I understand at least 60% of the words in the article and at least 20% of the meaning expressed when you string those words together.

Thank you anorlunda, I like the dimensional analysis approach. ... embarrassed I didn't go there. In fact, I have seen these figures quoted when expressing the value of the factory to the economy. So if you wanted to work out how many giga factories you need to support a fleet of electric...

Hello folks. I don't have any specific questions right now. I’m just saying hi and looking forward to teasing brains and being teased in return.

I'm working on battery designs and I wondered the same thing. What do you get when you integrate energy w.r.t. time? Being a lazy engineer with no redeeming value, I googled it and found this post. ... not helpful so I did a thought experiment: If I integrate Power measured at my battery...
