Abstract
An online method and apparatus for determining state of charge (SoC) and state of health (SoH) of batteries on platforms that present dynamic charge and discharge environments is disclosed. A rested open circuit voltage (OCV) may be estimated online using a battery dynamic model along with measured terminal voltage, current and temperature. The SoC and SoH can then be determined from this estimated OCV. The apparatus and methods may estimate SoC and SoH of a battery in a real-time fashion without the need to a) disconnect the battery system from service; b) wait for a predefined rest time; or c) depolarize the battery.
