Publication number: 20230006271Abstract: Systems and apparatus may carry out analysis of battery physical phenomena, and characterize batteries based on phenomena occurring in particular time and/or frequency domains. These systems may be additionally responsible for charging and/or monitoring a rechargeable battery. Examples of battery physical phenomena include mass transport (e.g., diffusion and/or migration) in battery electrolytes, mass transport in battery electrodes, and reactions on battery electrodes.Type: ApplicationFiled: September 9, 2022Publication date: January 5, 2023Inventors: Dania Ghantous, Fred Berkowitz, Nadim Maluf, Christina Peabody
-
Publication number: 20220317199Abstract: Batteries and associated charging conditions or other operating conditions are evaluated by a computational model that classifies or characterizes the battery and associated conditions. Such battery model may classify batteries according to any of many different considerations such as whether the conditions are safe or unsafe or whether the conditions are likely to unnecessarily degrade the future performance of the battery. In some cases, the battery model executes while the battery is installed in an electronic device such as a smart phone or a vehicle. In some cases, the battery model executes and provides results (e.g., a classification of the battery) in real time while the battery is installed and being charged.Type: ApplicationFiled: June 23, 2022Publication date: October 6, 2022Inventors: Dania Ghantous, Fred Berkowitz, Nadim Maluf

Patent number: 11152806Abstract: Disclosed is a method for identifying a battery type and/or a battery user. Measuring circuitry may be used to collect battery parameters that may be analyzed by control circuitry to create an adaptive charge profile that is applied to a battery by charging circuitry. Battery parameters may be recorded in a battery use signature. Logic may be used to process a battery use signature and identify a single user across multiple battery operated devices and/or discriminate between multiple users of a device. In some cases, battery use signature may be used to identify battery information including the make, model, and lot from which the battery was manufactured.Type: GrantFiled: August 14, 2019Date of Patent: October 19, 2021Assignee: Qnovo Inc.Inventors: Nadim Maluf, Fred Berkowitz
