MUMBAI, India, Sept. 26 -- Intellectual Property India has published a patent application (202441020412 A) filed by Sun Mobility Pte Ltd., Singapore, on March 19, 2024, for 'systems and methods for predicting/evaluating state-of-varibale (sox) of an energy storage device.'
Inventor(s) include Praveen Kumar Nambisan T M; and Saravanan Meenatchisundaram.
The application for the patent was published on Sept. 26, under issue no. 39/2025.
According to the abstract released by the Intellectual Property India: "The present invention discloses methods for predicting a SoH of an energy storage device by a SoX prediction engine (100). The method includes obtaining an energy storage device health indicator parameter. The energy storage device health indicator parameter includes a peak of ICA curve, a voltage at an ICA peak, an area under the ICA peak, an initial voltage of an ICA curve, valley point of Differential Voltage Analysis (DVA) curve, and capacity at DVA valley point. Further, the method includes configuring a SOH prediction model based on the obtained energy storage device health indicator parameter. Further, the method includes predicting the SoH of the energy storage device (170) by using the SOH prediction model. The proposed method can be used to accurately predict or estimate the energy storage device degradation without interrupting a normal operation of the energy storage device (170)."
