Calculating offgassing of lead-acid batteries


Recommended Posts

Certainly nobody would ask that boring question for free!

 

This begs the question:

 

How do you calculate the hydrogen offgassing of a bank of lead-acid storage batteries?

Ur a sick puppy Ronin. I spent 3 weeks refining the calculation for hydrogen offgassing of various banks of lead-acid storage batteries at Palo Verde nuclear plant about 5 years ago. It was one of my finer moments showing that the plant's previous calculation was inadequate. Luckily the ventilation was about 25 times more than was needed to keep hydrogen levels below the Lower Exposive Limit.

 

If you want the calc, PM me and I'll send it to you. It's sure to send anyone into snooze land.  :killself:   :lazy:

 

To think, this is the sort of stuff I live for. Seems so mundane. Robotics is much more interesting!

Got no idea what it all means, but looks impressive :)

Ahh.. I see the answer is 6.. As I suspected.

Now if I could just figure out what the units should be.

How the hell did u get six?

I got the answer as 42.

Luckily its also the answer of the meaning of life.

 

Yeah a terrible joke for the nerd inside me to admit i have read those books.( thought the movie was terrible)

 

 

Bah Humbug

we likely have different units.. THAT's the problem. Yes.. spent many years up to my ears in those books. Would not want to do that again.

We just need some measurements to throw into the equations. 

 

What is the area of the anode and the cathode?

 

Charge voltage?

 

Charge current?

 

I'll assume the electrolyte is optimum.

 

It isn't rocket science, anyone should be able to work it out with high school math, now that we know the formula.
