  • Publication number: 20250192595
    Abstract: An electronic device and a power supply method thereof are provided. The electronic device includes a host and an adapter. The host includes a charger circuit, a first controller chip and a controller. In a power connection state, the charger circuit receives DC power from the adapter to supply power to a system load within the host. The first controller chip communicates with a second controller chip included in the adapter to obtain an identification code and power supply capability information of the adapter. The controller determines whether the adapter meets a specific specification based on the identification code. When the adapter meets the specific specification, the controller periodically obtains a real-time internal temperature of the adapter from the second controller chip, analyzes it together with the power supply capability information, and establishes a power supply plan suitable for a boost mode.

  • Patent number: 10719111
    Abstract: A multiport connector and a power control method are provided. The multiport connector comprises a power output port and multiple power input ports. The power output port is connected to an electronic device. The power input ports are connected to multiple power adapters to form multiple power transmission paths. Each power transmission path comprises a power line, a detecting circuit and an impedance component connected to the detecting circuit in series. Therefore, when the electronic device is connected to the multiport connector, the electronic device detects the equivalent impedance formed by the impedance components on the detecting circuits to adjust an upper limit of load power.

  • Patent number: 9608476
    Abstract: A charging system includes a transmission line, a power adaptor, and an electronic device. The transmission line includes a first terminal and a second terminal. The power adaptor is coupled to the first terminal and generates a charging voltage and a first voltage signal. The charging voltage is at a first voltage level. The electronic device is coupled to the second terminal and receives the first voltage signal. When the first voltage signal is larger than a first preset voltage signal, the electronic device outputs a second voltage signal to the power adaptor. When the second voltage signal is larger than a second preset voltage signal, the power adaptor adjusts the charging voltage into a second voltage level.
