  • Method of Computing State of Charge and Battery State of Charge Monitor
    Publication number: 20150276885
    Abstract: Disclosed herein are a method of computing an estimated SOC and a battery state of charge (SOC) monitor. An embodiment method for computing an estimated SOC includes periodically measuring a present battery current and a present battery voltage. A hysteresis compensation value is then computed based on a previous SOC, the present battery current, and the present battery voltage when a change in battery current exceeds a threshold. The estimated SOC is then determined based on the hysteresis compensation value and a baseline SOC determined based on the present battery voltage and the present battery current.
