Systems and processes are provided to detect an improper external power supply. An example includes a processor in communication with an internal battery. The processor receives an indication that the internal battery is receiving power from an external power supply. The processor determines a first output current of the internal battery. An error is generated indicating the internal battery receives insufficient power from the external power supply. The error indicates the external power supply is faulty in response to the internal battery intermittently discharging while receiving a power from the external power supply.

Method and apparatus for improper power supply detection

Systems and processes are provided to detect an improper external power supply including a battery having a battery current output, a power supply for receiving an external voltage and an external current from an external power supply and for generating a control signal in response to receiving the external voltage, a processor operative to determine a first polarity of the battery current output at a first time in response to the control signal, to generate an error indicator in response to the first polarity being indicative of a discharging battery, and a display operative to display a user warning indicative of an improper external power supply in response to the error indicator.

Systems and processes are provided to detect a deeply discharged rechargeable battery. A process includes initiating a processor operative to perform a function within a battery-operated device, determining a first output voltage of a battery, charging the battery with a battery charger for a duration of time between three and seven seconds in response to the first output voltage being less than a cutoff voltage, rebooting the battery-operated device, determining a second output voltage of the battery, providing a user prompt indicative of battery fault in response to the second output voltage being less than the cutoff voltage, and shutting down the battery-operated device.

Method and apparatus for deeply discharged battery detection

A system and method to disconnect a battery from a load circuit when the battery temperature is outside a selected high threshold or a low threshold. A plurality of temperature sensors are provided for sensing a high battery temperature and a low battery temperature. If the either the high temperature sensor or the low temperature sensor outputs an error signal, the battery is disconnected from the load circuits. The disconnection from the load circuits is carried out by disabling at least four different circuits, any one of which alone will disconnect the battery from the load circuits. These four circuits include a battery switch circuit, a power control circuit, a charge control logic circuit and a voltage regulator circuit. The plurality of temperature sensors provides a backup system in the event any one of the temperature sensors is defective.
