  • Patent number: 11014462
    Abstract: A method for charging a battery in an electric or hybrid vehicle provides an alternative to switching to low tap. In accordance with this method, if a tap cross occurs, an OBCM reduces its power limit by a configurable amount and then retries charging at a lower level. This process can be repeated as many times as it takes to find a power level that prevents a tap cross. Advantageously, the battery can be charged in the shortest amount of time instead of limiting the power to the low tap level. A charging system implementing the method is also provided.

  • Patent number: 10948973
    Abstract: An electronic device may have a power system with a battery. The power system receives power such as wireless power or wired power and uses a portion of the received power to charge the battery as needed. Control circuitry in the portable electronic device is used to run background processes such as image processing tasks, data synchronization tasks, indexing, and other background processes. In some circumstances, such as when the battery is below a certain state of charge threshold, background processes may be stopped so that the battery is charged as fast as possible. Once above this initial state of charge threshold, background processes may be performed during charging as long as the temperature and state of charge of the battery do not exceed safety temperature and safety state of charge values. Performing background processes in these conditions ensures requisite background processing tasks are completed while preserving battery health.
