world’s first 100 MWh-class battery energy storage facility using 628 Ah ultra-large battery cells has entered operation.
Big cells aren’t necessarily good… if something goes wrong that’s a lot of energy being impacted. If a cell goes bad, that’s a more expensive option repair. I’m sure there’s other issues as well.
It can save on initial costs though in various ways as well.
When you build your battery farm, report back and tell us about the size of cells you chose.
Ah is not a good unit for explaining capacity, it’s better to use Joules. Ah is better suited to throughput because it informs the maximal load that can be applied.
Agreed Ah are bad.
MWh are equivalent to J. Specifically 1MWh is 3.6GJ
Those look like Retro Encabulators

628 Ah at what voltage?

I hate how battery systems are rated. They never give the full picture. “This is a MW system” cool, but how much storage?

It’s in MWh, what more do you want?

Yeah, I really want to be impressed and am sure I will be. Just give me the specs

v*a=w
so ? * 628 = 1,000,000
you do the math part, I’m lazy

Me too, that’s why I want it in the article.
