Abstract

The invention provides an electronic device. The electronic device comprises a core circuit, a battery, a power supply control circuit and a controller for detecting the load power of the electronic device once at a time interval. When the detected load power is greater than the first starting power of the power supply control circuit, the battery and a charger simultaneously supply power to the core circuit, the first starting power is greater than and directly proportional to the first fixed power, and the first fixed power is the power supplied to the core circuit through the charger limited by the power supply control circuit. When the load power is between the maximum rated output power and the first starting power continuously n (n>3) times or the load power is greater than the firststarting power, the controller changes the first fixed power of the power supply control circuit to the second fixed power.

Description

technical field [0001] The invention relates to a power supply technology of an electronic device, in particular to a power supply technology for dynamically adjusting a battery to supply power to a core circuit in an electronic device. Background technique [0002] Generally speaking, almost all existing notebook computers support a charger boost function. For example, a general notebook computer will set a fixed power (constant power, CP) to 85% of the maximum rated output power of the charger, so that the total load power of the notebook computer is higher than a certain power (for example: charging When the maximum rated output power of the charger is 90%), the charger supplies power to the notebook computer with 85% of its maximum rated output power, and the remaining required power is provided by the battery. However, when the notebook computer is connected to the charger and the charger is provided with an AC power by an external power source, the power of the batter...
