Patent number: 11165270Abstract: An electronic device includes a battery and a battery management system. The battery management system is configured to derive a predicted battery demand based on observed usage patterns to predictively charge the battery to healthily accommodate the predicted battery demand. The battery management system is further configured to determine a predicted deviating battery demand based on a contextual signal. The predicted deviating battery demand differing from the predicted battery demand. The battery management system is further configured to predictively charge the battery to healthily accommodate the predicted deviating battery demand.Type: GrantFiled: May 20, 2019Date of Patent: November 2, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Craig Daniel Owen, Dongli Zeng, Jeffrey Duane Bruce
