  • Charge control device, charging system, and charge control method
    Patent number: 10965145
    Abstract: A charge control device for controlling charging of a secondary battery by using a current limit function of an external power supply includes: a charge control element arranged to be connected in series between the external power supply and the secondary battery; a constant current control unit configured to control an output current of the charge control element to be constant; a constant voltage control unit configured to control an output voltage of the charge control element to be constant; and an ON state setting unit configured to set the charge control element to an ON state, wherein the charge control element includes a control terminal to which a control signal for controlling the output current and the output voltage is input, and is composed of a single output element.
