  • Patent number: 10554060
    Abstract: A power supply terminal, and a charging control method are disclosed. The power supply terminal includes a USB port, a switch, a power source module, and a processor, where the USB port is configured to connect to a power receiving terminal; one end of the power source module is connected to a power source pin VBUS of the USB port and is configured to charge the power receiving terminal by using the power source pin VBUS; a first end of the switch is connected to the data pin D+ and a second end of the switch is connected to the data pin D?; when the switch is on and the processor detects that a drop amplitude of the output voltage of the power source module exceeds a preset value, in a process in which the power source module outputs a voltage to charge the power receiving terminal.

  • Patent number: 9819172
    Abstract: A thermal protection circuit which relates to the field of electronic technologies can detect temperature of multiple locations simultaneously and adjust a preset threshold flexibly, thereby improving system reliability. The thermal protection circuit includes: at least one temperature sensor, a detection circuit, an execution circuit, a self-locking and triggering circuit, a protective temperature regulation circuit, and a power supply circuit. The at least one temperature sensor converts a temperature signal into an electrical signal and sends the electrical signal to the detection circuit; the detection circuit detects whether temperature reaches the preset threshold, and sends a turn-off signal to the execution circuit if the temperature reaches the preset threshold; the execution circuit cuts off power supply to the system; and the self-locking and triggering circuit maintains, a power-off state of the system until a power switch is triggered.

  • Patent number: 9461340
    Abstract: A battery, a battery assembly, and a user equipment are disclosed. The battery includes a circuit board and a cell. The circuit board includes a first contact, a second contact, a third contact, a fourth contact, a battery management module, and a control switch. The first contact reports a capacity of the cell in the battery, or in the battery and a cascaded battery to an upper-level battery or an electricity load; the second contact receives and output the capacity of the cell in the cascaded battery; when the control switch is opened, the third contact is connected to the cell in the battery to charge or discharge the cell in the battery; when the control switch is closed, the fourth contact is connected to the third contact; and the battery management module triggers opening or closing of the control switch.
