In practice, the relationship between battery capacity and discharge current is not linear, and less energy is recovered at faster discharge rates. During discharge, ohmic losses in electrolyte and contacts lower voltage. Internal impedance increases due to lowering electrolyte concentration and electrode sulfation.
As a lead-acid battery discharges, its voltage decreases. Instead of being linear, the rate of voltage decrease follows a distinctive curve. The discharge voltage profiles of various lead-acid battery types, such as flooded, gel, and AGM batteries, may differ slightly from one another.
1. Understanding the Discharge Curve. The discharge curve of a lithium-ion battery is a critical tool for visualizing its performance over time. It can be divided into three distinct regions: Initial Phase. In this phase, the voltage remains relatively stable, presenting a flat plateau as the battery discharges. This indicates a consistent energy output, essential for
The lead-acid battery discharge curve equation is given by the battery capacity (in ah) divided by the number of hours it takes to discharge the battery. For illustration, a 500 Ah battery capacity that theoretically discharges to a cut-off voltage in 20 hours will have a discharge rate of 500 amps / 20 hours = 25 amps.
The next phase of discharging is in the bulk or main part of the discharge. During this phase, most of the energy of the battery is discharged. For a lead acid battery, this happens in a relatively linear manner, with the voltage dropping in proportion to the Depth of Discharge, or inversely proportional to the State of Charge.
There are typically three signifcant regions to a battery discharge curve. Assuming you start with a fully charged battery, when the discharge starts, the "surface charge" of the battery is taken off, and the voltage drops rapidly, albeit for a very short amount of time. The next phase of discharging is in the bulk or main part of the discharge.
