How to monitor a lead acid battery?

Three common SoC monitoring methods – voltage correlation, current integration, and Impedance Track are discussed. State of charge of lead acid battery is the ratio of the remaining capacity RC to the battery capacity FCC . The FCC (Q) is the usable capacity at the current discharge rate and temperature.

How a lead acid battery self-discharge?

3.3 Battery Self-discharge The lead acid battery will have self-discharge reaction under open circuit condition, in which the lead is reacted with sulfuric acid to form lead sulfate and evolve hydrogen. The reaction is accelerated at higher temperature. The result of self-discharge is the lowering of voltage and capacity loss.

How to make a lead acid battery?

1. Construction of sealed lead acid batteries Positive plate: Pasting the lead paste onto the grid, and transforming the paste with curing and formation processes to lead dioxide active material. The grid is made of Pb-Ca alloy, and the lead paste is a mixture of lead oxide and sulfuric acid.

How does Texas Instruments determine a lead acid battery's SoC?

R DC must be compensated for a discharge current and temperature. Texas Instruments uses the Impedance Track method to determine SoC of lead acid batteries . While current off, the OCV is measured, which is used to determine the SoC and to update Q MAX. When discharging, both discharge current and voltage are measured.

What is state of charge of lead acid battery?

State of charge of lead acid battery is the ratio of the remaining capacity RC to the battery capacity FCC . The FCC (Q) is the usable capacity at the current discharge rate and temperature. The FCC is derived from the maximum chemical capacity of the fully charged battery Q MAX and the battery impedance R DC (see Fig. 1) .

What happens when a lead acid battery is discharged?

When the lead acid battery is discharging, the active materials of both the positive and negative plates are reacted with sulfuric acid to form lead sulfate. After discharge, the concentration of sulfuric acid in the electrolyte is decreased, and results in the increase of the internal resistance of the battery.
