Abstract
Systems, methods, and devices are provided for estimating a state-of-charge in an energy storage system. The systems, methods, and devices may measure a current and a voltage related to the energy storage system, generate a model-based state-of-charge estimate based thereon, generate an aggregated state-of-charge estimate based on the model-based state-of-charge estimate, generate an adaptation current based on the measured current, aggregated state-of-charge estimate, and the adaptive state-of-charge estimate, and update the adaptive state-of-charge estimate based on the measured current and the adaptation current. The systems, methods, and devices may also provide a tracking indication whether the adaptive state-of-charge estimate is tracking between upper and lower confidence limits.
