Pulsing a coil with a cap pulser

[Faraday88]

Have you determined what parameters you will use to determine the point at which the battery is fully charged?

@all,
My guess is the 15.25V Cold boiling finish mark!
we can trip-control at this point like a regular charger (ofcourse it does'nt do it at this point though).

Thank you

Yes, I did theorise to myself that this method of charging should provide a deeper charge and improved rejuvenation capabilities, however I have not done enough testing to prove that theory yet.

Anyhow, I did design this primarily as a practical "solar charger" so the next step is to design a circuit that will stop charging when the battery is fully charged.

After that I'm going to revisit my 3 battery switch circuit that rotates the batteries when required, but still using the "pulsing the coil" method that is the topic of this thread. The end goal is the "self-running" battery charger - still chasing that dream

Hi JK,
2 Batteries for 24V as the input to the BLC.... oh yes another feature is the rotatability of the input/output batteries... even if you have low Solar light you can have the panel in series(ensure a diode in line) with a Battery(input) and drive this circuit. This circuit would be a better de-sulfator for Rejuvenation..my Circuit that includes the resistor would bring all the High-impedance inside the battery and dump it in the resistor plus more power there!! resulting further lowering of Battery impedance.. a deeper charge! I shall do the testing and share it here with the group.
Best Regards,

If we are charging with a spike we would need to disconnect the charger and wait for some period of time before checking the battery voltage since the spike would go well over 15.25 volts. Maybe the circuit could quickly measure battery voltage between spikes.
If we were charging with steady current, the battery voltage would vary depending on charging current so, again, we would need to disconnect the charger and wait some period of time to check the battery voltage.
After the charger is disconnected the battery can take considerable time to settle at a significantly lower voltage.
It would be nice if there was a simple way to check specific gravity of the battery acid during charging. Of course that would only cover that one cell.

Correct on all counts Richard.

I'll be using the same design that was used in one of Bedini's commercial chargers. Charge, rest, measure. Charge, rest, measure. Compare

It's a reasonably simple circuit. Just a couple of relays and a PIC or Arduino. The code takes care of when to charge, rest, measure and compare stages.

Hi Richard,
Indeed! you have pointed a very good way to sense the Charge-state in a battery since the Specific gravity of the electrolyte is a direct indication, more than the Voltage read-out since a bad cell would never indicate in terms of the effective Voltage(12v). Individual SP monitoring, although seems impractical, should be nevertheless a right approach in my view. just that we need to have a commercial electronic Specific gravity sensor available!!

Will you be sharing the details of that work?

Yes Richard. Note that it won't be Bedini's proprietry circuit, but my interpretation of it.

As soon as I have something replicatable I'll post it.

Hi JK,
Just wondering how can the circuit be not Bedini proprietary when you are claiming to use his 'Bedini Large comparator' how would it matter anyway? unless you better it and then claim you're bettering over the prior art
wouldn't you patent it then???

Faraday, not sure what you're asking but I'll try to write an answer anyway.

We're talking about a circuit that controls the operation of the previously posted system of a "Pulsing a coil with a cap pulser". It has no more in common with the proprietary circuit of the "Bedini Large Comparator" than a horse has to a cart.

Hi JK,
Your circuit interpretation is a multi-stage booster to the 'Bedini Large comparator' in a sense. so its a spin-off technology of the same.

Faraday, I have the distinct feeling that we're not on the same page.

Please back up to the part where i said "the next step is to design a circuit that will stop charging when the battery is fully charged." and then read again from there. (Post #54)

I've moved on from the actual charging circuit. Richard and I were talking about "the next step".

Do try and keep up m'boy!
