  • Battery-driven electronic device
    Patent number: 9983649
    Abstract: A battery-driven electronic device includes a battery for outputting a battery voltage, a plurality of loads, a system unit, and a battery energy manager which is electrically connected with the battery, the loads and the system unit. The battery energy manager is adapted for detecting the battery voltage and set with a cutoff threshold, and a low-voltage threshold higher than the cutoff threshold. When the battery voltage is equal to or lower than the low-voltage threshold, the battery energy manager stops supplying power from the battery to at least one of the loads, and outputs a suspension command for the system unit to perform suspension process. When the battery voltage is equal to or lower than the cutoff threshold, the battery energy manager stops supplying power to the loads and the system unit.
