Publication number: 20240116395Abstract: A method of controlling a vehicle where the vehicle includes a first battery, a second battery, a solar cell, a power converter, a power divider, and a power supply. The method includes producing power by the solar cell and converting a voltage of the produced power by the power converter. The method also includes transferring, by the power divider, the power produced by the solar cell to at least one of the first battery or the second battery based on a state of charge (SoC) of the first battery and a SoC of the second battery. The method also includes stopping the power supply from supplying power to the power converter when a time for which the power is supplied to the power converter is longer than or equal to a predetermined reference time.Type: ApplicationFiled: December 20, 2023Publication date: April 11, 2024Applicants: HYUNDAI MOTOR COMPANY, KIA CORPORATIONInventors: Jin Kim, HanYoung Park

Patent number: 11644042Abstract: A compressor that vibrates a rotary shaft or changes an operating frequency of a motor, in response to a vibration frequency of a discharge passage falling outside of a normal range. The compressor may include one or more impeller configured to draw in and compress refrigerant; a motor configured to rotate the one or more impeller; a rotary shaft, to which the one or more impeller and the motor are coupled; at least two thrust bearings that limit vibration of the rotary shaft; a vibration measuring sensor configured to measure a vibration frequency of a discharge passage; and a controller configured to control the at least two thrust bearings based on the vibration frequency. Upon determining that the vibration frequency falls outside of a normal vibration frequency range, the controller controls the at least two thrust bearings to vibrate the rotary shaft a predetermined number of times.Type: GrantFiled: February 11, 2021Date of Patent: May 9, 2023Assignee: LG ELECTRONICS INC.Inventors: Hanyoung Park, Yoonjei Hwang
