There are many studies on the SOC estimation of lead–acid and Li-ion batteries, especially the Coulomb counting method [33, 34]. However, the research work conducted in this article differentiates by investigating the discharging behavior of a lead–acid battery in extended and varying conditions.
In this research, the ampere-hour integral method is validated experimentally via a domestic lead–acid battery. It is worth mentioning here that the proposed method is generic in its implementation.
The determination of SOC estimation by this method is carried out by adding up the incoming charge or the charge coming out of the battery within a certain period of time. Charge summation can be done by summing the current in the battery, both at the time of charging and discharge.
In addition, the device's integrated precision (±5% battery discharge measurement accuracy) coulomb counter provides accurate monitoring of accumulated battery discharge in long-life non-rechargeable battery-powered applications which in many cases have extremely flat battery discharge curves.
