Battery and Peukert's constant

BD Batteries - Battery Efficiency and Peukert's Law

I believe that conditioning a battery is to increase the Peukert constant and maximum theoratical is 2. When Peukert's constant >1, one can see the fishiness in energy content when you vary your current. This of course assuming that the capacity of the battery is constant (since it depends on the chemical reaction). I suppose one can exploit Peukert's constant>1 effect.

many with pulse charger concepts,
and the ever-present Bedini Klan
have believed this for years
for batteries that will see slow disharge rates.

The secret isn't in the charger,
it is in the battery's electro-chemical stasis.

The chemical reaction is to slow to react
to those never ending pulse trains in them...

Actually, you're right. If Peukert's constant is 2, if you lower your current in half, you double the amp hour. Cut it down to 1/4, you actually quadrupble the amphour.

However, recharging process require Bedini technique of pulsing a high voltage cap, else no gain.

I'll probably get penned pro-Bedini for this, sigh...

But I believe there is something to the concept of
providing charge to a chemical reaction based cell
at a rate which exceeds It's ability to react properly
to the served energy in the form of sharp pulses
that has an added effect above the norm.

there is charge stasis, and there is charge resident.

Very few articles or documents address this.

What most people forget!

Listen everyone is treating batteries like they are solid state. They are not solid state devices. They are electro chemical devices. They have a real flow inside of them. This flow also has inertia. Just like you have inertia in a wave on a pool of water there is the same thing inside of a battery. This flow can be tapped along like one can do with a swing and get more in response then you inputted. It's very simple kind of thinking.

We tend to forget there is a fluid inside of most batteries and when there is not then you still have a chemical reaction that can be motivated to move without 100% input. This is the charging they are seeing. Start a flow or a resonance of flow and let it play out while only inputting what is needed to keep the flow going. This is the effect.

Anyone can see this. Take a load and temporarily connect it to the battery and the flow will start. now quickly take the load off and watch the batteries voltage after disconnecting the load. The battery will surge a second after the load was disconnected. That response in the inertia of the fluid or chemical reaction in the battery and this is exactly what we have been seeing in all of the applications that tend to charge batteries even while powering the load or seem to be powering commonly called pulsing.

If one wanted to maximize any battery then one would need a battery management system to monitor and adjust the load on the fly. Matching the load, whatever that might be, would be essential to extending the battery or even increasing the batteries capacity while operating by using this response from the battery to enhance the loads performance or even the batteries charge.

They use bms's on Lifepo4's so why shouldn't we use them on plain jane batteries. Except this BMS would run even when the load is not present to recharge the cells when not in use by this surge event.

What I think is that we could have two banks of batteries. One being the run batteries. The other bank is the recharge batteries. While one bank is working the other can recharge and recondition it's state through the BMS.

a New way to charge batteries is in the works . It takes the charge time down from hours to mins using a 25 gighertz signal on the plates to accept ions easly . Check this out New charging method could greatly reduce battery recharge time
As a Ham radio operator this is very interesting quote:researchers simulated the lithium-ion battery-charging process by simulating the intercalation (i.e. “insertion”) of lithium ions into the battery’s graphite anode. Although intercalation is just one part of the charging process (along with diffusion), it dominates the charging time.

In the charging process, lithium ions first diffuse within the battery’s electrolyte until they reach the graphite anode. At this interface, ions must overcome an energy barrier in order to be intercalated into the anode.

In their simulations, Hamad and his team found that an additional oscillating electric field can lower this energy barrier, enabling lithium ions to intercalate more quickly into the anode. The oscillating field also increases the diffusion rate, which helps further reduce the overall charging time, albeit to a lesser extent.

Thank you guys for the input,

I've figured out the calculation for discharge and charging the battery today.

(1/2)(I^k)(R)(t)

I= current / pulse current
k= Peukert constant
R = battery internal resistance
t = time (for continuous operation) / frequency (for pulse operation)

This equation works for both discharge and charging. As one can see, we can send more current back when charging and we'll have a gain. However, as current goes up, time/frequency has to go down. This is where Peukert constant play an important roll. The method is to charge up a cap real high and disruptive discharge it to gain a huge a mount of current.
