  • Electric vehicle and charging apparatus thereof
    Patent number: 11025161
    Abstract: Disclosed are an electric vehicle capable of improving the charging efficiency of a charging apparatus by reducing the switching loss that may occur in the charging apparatus of an electric vehicle and a charging apparatus thereof. To this end, a power factor correction apparatus of an on board charger includes a first boost circuit receiving AC power through a first inductor to charge a load, a second boost circuit receiving the AC power through a second inductor to charge the load, and a third inductor provided between a leg of the first boost circuit and a leg of the second boost circuit so that parasitic capacitors of the first boost circuit and the second boost circuit are discharged.
    Type: Grant
    Filed: October 25, 2018
    Date of Patent: June 1, 2021
    Assignees: Hyundai Motor Company, KIA Motors Corporation, Korea Advanced Institute of Science and Technology
    Inventors: JongPil Kim, Jaehyuk Choi, Woo Young Lee, HanShin Youn, Gun-Woo Moon, Jae-Ii Baek, Jung-Kyu Han, Moo-Hyun Park

  • Electronic device and method for controlling charging operation of battery
    Patent number: 10103562
    Abstract: The present invention relates to an electronic device and a method for controlling a charging operation of a battery. The charging control method includes charging a battery using a first charging mode, if a current voltage of the charged battery coincides with a predetermined voltage, decreasing an intensity level of a charging current and charging the battery using the decreased charging current intensity, and if the decreased charging current intensity coincides with a predetermined current intensity, converting from the first charging mode to a second charging mode and charging the battery using the second charging mode.
