Can a hydrometer measure SOC of a flooded lead acid battery?

Figure 2: Voltage band of a 12V lead acid monoblock from fully discharged to fully charged The hydrometer offers an alternative to measuring SoC of flooded lead acid batteries. Here is how it works: When the lead acid battery accepts charge, the sulfuric acid gets heavier, causing the specific gravity (SG) to increase.

Abstract: This study aims to design and assess the simulation of the state of charge (SoC) estimation on lead-acid batteries using the Coulomb counting (CC) and feed-forward neural network (FFNN) method. Also, this study compared the effectiveness of each technique.

Can you use a hydrometer on a lead acid battery?

Although hydrometers have been traditionally used to make specific gravity (SG) measurements, modern lead acid batteries consist of electronic sensors that provide real-time SG measurements and yield fairly accurate SOC values. However, this method is quite exclusive to lead acid batteries and cannot be used with other cell chemistries.

Can a lead acid battery be charged with a flat discharge curve?

While voltage-based SoC works reasonably well for a lead acid battery that has rested, the flat discharge curve of nickel- and lithium-based batteries renders the voltage method impracticable. The discharge voltage curves of Li-manganese, Li-phosphate and NMC are very flat, and 80 percent of the stored energy remains in the flat voltage profile.

Which battery chemistry is best for a lead acid battery?

Each battery chemistry delivers its own unique discharge signature. While voltage-based SoC works reasonably well for a lead acid battery that has rested, the flat discharge curve of nickel- and lithium-based batteries renders the voltage method impracticable.

Why do lead-acid batteries have a linear curve?

It can be seen that lead-acid batteries have a relatively linear curve, which allows a good estimation of the state of charge : for a measured voltage, it is possible to estimate fairly precisely the value of the associated SoC.
