Abstract: A system includes a processor, a charger circuit and a battery management unit (BMU). The charger circuit charges a battery. The BMU includes an intelligent boot module that can send a boot signal to the processor based on information including a battery condition and system information. The processor starts a boot sequence based on the boot signal.

Abstract: A battery includes a battery cell and processing circuitry. The processing circuitry is configured to determine an estimated temperature of the battery cell as a function of various models. The models include a battery cell heat generation model that receives a first input indicative of a battery voltage measurement, a second input indicative of a voltage corresponding to a battery open-circuit voltage (OCV) model, and a third input indicative of a battery current measurement. The models also include a gas gauge and system heat generation model that receives the third input. The models also include a battery and gas gauge heat transfer model that receives a fourth input indicative of a gas gauge temperature measurement.

Abstract: The disclosed technology relates to a portable electronic device. The portable electronic device may comprise a battery, a battery controller, and a system controller. The battery controller may be configured to determine real time battery state information associated with the battery, the real time battery state information including a system load current draw, a battery age indicator, and a battery temperature. The system controller may be configured to determine a user initiated current low voltage mode state of the portable electronic device of a plurality of low voltage mode states, receive current battery state information from the battery controller, and adaptively generate a real time shutoff voltage threshold based on the current determined low voltage mode state and the current battery state information.
