Title: STATE OF CHARGE ESTIMATION OF ENERGY STORAGE SYSTEMS
Abstract:
State of Charge estimation of energy storage systems A system and method are described, which can estimate the state of charge of an energy storage device such as a thermal storage device. Embodiments of the invention can receive signals from a single, cheap state sensor such as a temperature sensor in a thermal energy storage medium such as one using PCM. Embodiments of the invention provide a system and method which can estimate the state of charge of an energy storage device by making use of a model of the storage device such as of the PCM tank and of the history of the output of the state sensor such as the temperature history of the storage device, e.g. a PCM tank. One of the main problems addressed by embodiments of the present invention with PCM materials is that the temperature is no longer a simple measure of the heat content and more complex models are required.
