Abstract: discussed is a protection apparatus that may identify an accumulated charging time period of a charging current applied at least one battery cell and determine whether to permanently block charging and discharging of the at least one battery cell by comparing an accumulated charging time period with a predetermined threshold time period, thereby preventing battery cell ignition due to lithium plating occurring in the battery cell caused from a charging current.

Abstract: a battery control apparatuses may include a measuring unit for measuring a voltage of a battery, a memory for storing a multi-stage charging protocol data, and a processor for identifying a soc of the battery based on the voltage measurement value. the processor may perform a temporary discharging procedure, when the soc of the battery reaches the first criterion soc while the constant current charging procedure using the first current rate is in progress. the processor may also determine an adjusted second current rate different from the second current rate based on discharging information of the temporary discharging procedure and, after the temporary discharging procedure is finished, perform a constant current charging procedure using the adjusted second current rate.
