Patent number: 12166369Abstract: A portable power bank including a rechargeable battery may detect loss of capacity in the power bank battery. The power bank determines a nominal capacity of the power bank, and an actual capacity of the power bank, the actual capacity being less than the nominal capacity. The power bank compares the actual capacity to the nominal capacity to determine a health value of the power bank battery. When the power bank battery health value is at or below a threshold value, the power bank transmits an indication of the health value to a mobile computing device.Type: GrantFiled: November 13, 2023Date of Patent: December 10, 2024Assignee: DURACELL U.S. OPERATIONS, INC.Inventors: Jordan Bourilkov, John Rotondo, Francisco Jose Restrepo, Sergio Coronado Hortal

Patent number: 12154389Abstract: An approach to forecasting battery health as a dynamic time-series problem as opposed to a static prediction problem is presented. Systems and methods disclosed herein forecast a trajectory to failure by predicting a path to failure as opposed to only predicting when the battery may fail. A machine-learning model is implemented that extracts unique features taken from time-series data, such as time snippets of charging data. The raw time-series data may include current voltage and temperature with complex transformations and without capturing a full cycle, which permits wider applicability to instances of varying depth of discharge (DoD).Type: GrantFiled: March 8, 2021Date of Patent: November 26, 2024Assignee: TOYOTA RESEARCH INSTITUTE, INC.Inventors: Linnette Teo, Chirranjeevi Balaji Gopal
