Batteries, chargers and inverters...

[Brett_Henderson]

I'm having a discussion with a forum member.. He'll remain nameless unless/until he cares to join this thread..

Basically, I'm saying that if you are running a device (or devices) from a battery system.. and there is no outside power source, you cannot get more life out of the system by adding an inverter/charger network, than you'd have by just running from the batteries themselves. This image shows his System A ..

Thanks now my head hurts, and when the ol'lady hears an explosion in the garage, I'm sending her your way!

How do you even get talking about something like this???

It didnt start with something like "My CB is better than your CB!" did it?

LOL.. no..  We were just talking about methods for running electronic devices where no outside power is available, and without having to use stuff like solar-panels, or wind-mills.

I'm just contending that you've got batteries on one side.. something that needs power on the other.. and that you can't get more use out of the batteries by trying to charge one, with the other....

As a long Retired Electrical/Electronic Engineer, the other un-named Member contacted me on this particular subject...

...and I put it all down to; "Assault and Battery"...

....which generally results in a Headache!... ...!

Deciding which way round to attach the Toilet Roll to the Toilet Roll Holder involves more calculation and decision making than I can cope with at the moment... ...!

If you do not use an outside source of power system B is correct.

Crash

Well.. obviously, if you're talking about bringing outside batteries

I'm not quite sure.. but it sounds like you agree with me in the last post

The way I see it, with system A, you would get a longer power output, but less output at any one point in time.

Good lord..

the idea of using one battery to charge another will not increase the total current..

I've kept telling you that's not what we're doing but you insist on stuffing the cart into the horse.

Hmmm.. ok.. I can sorta see something here. Your system would indeed be easier on the batteries in terms of how long you could use them.. long term.. but that is actually negated too.. because your system would have a shorter span between times when they'd have to actually be recharged.. more recharges per year.

My system is based on how long you could use a set of fully-charged batteries.

Another angle that popped into my head.. is that you might be trying to mitigate the inverter inefficiency. My system assumes an inverter matched to the load. But even that theory STILL takes us back to using one battery to charge another. If that act gained even the slightest bit of use; it would simly be a matter of cascading several system A's until the sum of those slight gains equalled the load.. and then the batteries would last until they physically failed..

Heck, we could cascade thousands of those systems and actually MAKE electricity above and beyond what we use, and sell it to our neighbors.
