Estimation of SOC of a lead-acid battery. Embodiments herein disclose methods and systems for determining State of Charge (SOC) of a lead acid battery in a vehicle. Embodiments herein disclose methods and systems for determining State of Charge (SOC) of a lead acid battery in a vehicle using discharge and charge correction factors. Embodiments herein disclose methods and systems for determining State of Charge (SOC) of a lead acid battery in a vehicle using a master OCV table based SOC estimation (SOCOCV) after the vehicle has been powered off, and a current throughput based SOC estimation (SOCEST) based on coulomb count integration (amp-second (As) integration) when the vehicle is operational. Embodiments herein disclose methods and systems for determining State of Charge (SOC) of a lead acid battery in a vehicle considering ageing of the battery and temperature.
