  • Publication number: 20190097434
    Abstract: The present disclosure discloses a charge control apparatus and method for energy saving and high speed cell balancing. According to the present disclosure, when any one of a plurality of battery cells reaches a fully charged state, charging is temporarily stopped. Additionally, a battery cell with the lowest state of charge is determined to be a target for supplemental charging and the remaining battery cells are determined to be a target for forced discharging. Subsequently, cell balancing including supplemental charging and forced discharging is performed. When among the battery cells being forcedly discharged the number of battery cells with the same state of charge as the state of charge of the battery cell being supplementally charged is equal to or larger than a reference number, cell balancing is stopped and charging is performed again. This cell balancing process is iteratively performed each time any one of the plurality of battery cells reaches a fully charged state.
