6 FAQs about [Battery diaphragm limits charging current]

Does DVCC reduce charge current limit?

Second, the charge current limit is dynamic, which means that somewhere between 95 and 100% SOC the battery will reduce the charge current limit. This is normal. If you enable DVCC, disable SVS and STS, and enable current limit then you should not have to see a reduction from your MPPT.

How many volts does it take to charge a battery?

You'll lose at least 1.7v from IN to OUT, and another nominal 1.25v from OUT to ADJ, so that's roughly a 3v drop. Your charger will have to be putting out at least 17v to charge the battery up to 14v. A good circuit for battery charging is a constant voltage circuit with current limiting. A few op amps and power transistors can do the whole thing.

How to charge a 14v battery?

Your charger will have to be putting out at least 17v to charge the battery up to 14v. A good circuit for battery charging is a constant voltage circuit with current limiting. A few op amps and power transistors can do the whole thing. One problem you'll likely experience with the LM338 idea is the regulator dropout voltage.

Why is my pylontech battery reducing the charge current limit?

Hi @rossmuller1. First, make sure that the GX sees both pylontech batteries, and not just one. Second, the charge current limit is dynamic, which means that somewhere between 95 and 100% SOC the battery will reduce the charge current limit. This is normal.

Why is my CCGX battery not charging?

It is most likely due to a cold temperature condition. Make sure the batteries are above 15 degrees C (as displayed in the CCGX), and it should increase. I do not have the Temperature / Charge Current derating table for these batteries. Perhaps you could request it from your Pylontech supplier and post it here?

What cables do I need to charge my aux 12V battery?

My thoughts of what you will need: Charging/equalizing cables compatible with the maximum current expected to charge the Aux-12V battery. Surely anything of at least of 4 mm^2 or 12AWG, for at least 20A and a couple of meters long, but 6 mm^2 or 10AWG is good up to 30A; and 8AWG goes up to 40A safely, without overheating.
