  • Patent number: 10447060
    Abstract: A charging device includes a main control circuit, a connecting interface, a power supply circuit and a detecting circuit. When an energy storage element connects to the charging device, the connecting interface is coupled to two terminals of a temperature control element. The power supply circuit is coupled to the connecting interface and the main control circuit. The detecting circuit is coupled to the connecting interface. When the energy storage element connects to the charging device, the detecting circuit generates a detecting signal being used to trigger the power supply circuit to provide a main operating voltage to the main control circuit. When temperature of the energy storage element exceeds a threshold, the temperature control element makes the detecting circuit not to generate the detecting signal, so the power supply circuit ceases to provide the main operating voltage to the main control circuit.
