  • Charging circuit, system and method, and electronic device
    Patent number: 10978898
    Abstract: A charging circuit, a charging system, a charging method, and an electronic device is provided. In the charging circuit, a control signal transmitted by a controller is received, and then it is determined whether the control signal is a first control signal. If it is determined that the control signal is the first control signal, a first set of switches is turned on and a second set of switches is turned off to cause an adaptation module to charge a first capacitor, a second capacitor and a battery. If it is determined that the control signal is not the first control signal, the second set of switches is turned on and the first set of switches is turned off to cause the first capacitor and the second capacitor to charge the battery.
