Lifepo4 State Of Charge Chart

Lifepo4 State Of Charge Chart - Because if i set it as 20v to 29.2v the battery would display 50. My lifepo4 24v battery without a load shows 26.77v which is twice the voltage in the12v chart showing it is close to 99% of capacity. I understand the downside of estimating capacity by voltage etc. These charts aren’t very useful for lfp batteries. And then step 2 kicks in until the charge voltage reaches 3.65v per cell. And in a discharge chart the curve goes ?. Whether it is a charge or discharge chart is easy to distinguish, in a charge chart the curve goes ?

Because of the lifepo4 being so linear, i'm actually setting up my voltimeters (that show capacity in a linear way) as 0% on 25.5v and 100% on 26.8v. My lifepo4 24v battery without a load shows 26.77v which is twice the voltage in the12v chart showing it is close to 99% of capacity. First step uses constant current (cc) to reach about 60% state of charge (soc); I discovered an xls worksheet in my stored file and took parts of that to create this chart, i did not create the worksheet and for the life of me, i can't remember where i found it in april of this year.

But i noticed it wasn't showing the exact voltage ranges that my battery data sheet does. My lifepo4 24v battery without a load shows 26.77v which is twice the voltage in the12v chart showing it is close to 99% of capacity. And then step 2 kicks in until the charge voltage reaches 3.65v per cell. These charts aren’t very useful for lfp batteries. I found some info on the manufactures (leoch) website depicting a line graph that shows the battery's relationship of ocv and state of charge (77 degrees f.). 70%soc while discharging (on the above chart) reads 12.95v.

First step uses constant current (cc) to reach about 60% state of charge (soc); Whether it is a charge or discharge chart is easy to distinguish, in a charge chart the curve goes ? As you can see the voltage readings are completely different at the same soc. I understand the downside of estimating capacity by voltage etc. Variations in actual chemistry and manufacturing tolerances, coupled with the very flat charge/discharge curve makes using terminal voltage as more than an approximate guide to state of charge really a hiding to nothing.

If the cells in your battery were well balanced, these two values would be correct: And then step 2 kicks in until the charge voltage reaches 3.65v per cell. Turning from constant current (cc) to constant voltage (cv) means that the charge current is limited by what the battery will accept at that voltage, so the charging current tapers down. A shunt is the only reliable way to measure state of charge.

A shunt is the only reliable way to measure state of charge. My data sheet shows 100% charge at 14.6v and 0% charge at 10.0v. I understand the downside of estimating capacity by voltage etc. Anywhere from 50 volts being 100% to 52 being 100% soc.

13.8V = (About) 100% 10.0V = 0% Everywhere Else Voltage And Soc Just Don’t Correlate All That Well.

I could not find anything comprehensive. I've looked at several places for a simple, easy to read at a glance chart document for lfp. Would a voltage chart showing what percentage of charge for a 24v battery be double the voltage of a 12v battery? I found some info on the manufactures (leoch) website depicting a line graph that shows the battery's relationship of ocv and state of charge (77 degrees f.).
