  • BATTERY MANAGEMENT METHOD, VEHICLE EMPLOYING THE METHOD, AND BATTERY
    Publication number: 20240383372
    Abstract: A battery management method includes obtaining a voltage-capacity profile in response to charging or discharging of a battery and diagnosing the state of the battery using an nth-order differential value (n being a natural number of 1 or greater) at at least one predetermined characteristic point obtained from an nth-order differential profile of the voltage-capacity profile.
    Type: Application

    Publication date: November 21, 2024
    Applicants: Hyundai Motor Company, Kia Corporation
    Inventors: Joon Keun YOON, Seung Beom Yoon
  • Apparatus for management of a battery, vehicle system having the same and method thereof
    Patent number: 12095298
    Abstract: The present disclosure relates to a battery management apparatus, a vehicle system including the same, and a battery management method. An exemplary embodiment of the present disclosure provides a battery management apparatus including: a processor configured to create a profile depending on a voltage of a battery cell when charging a battery, to determine uniformity of the battery cell based on the profile, and to perform battery management and control by using the uniformity; and a storage configured to store a profile for each battery cell, and an algorithm and data driven by the processor.
    Type: Grant
