BATTERY MANAGEMENT APPARATUS AND METHOD FOR PROTECTING A LITHIUM IRON PHOSPHATE CELL FROM OVER-VOLTAGE USING THE SAME

A battery management, including a voltage measuring unit electrically connected to multiple lithium iron phosphate (LFP) cells in an LFP battery, the LFP cells being connected in series, to individually measure voltage of each LFP cell and output a voltage value indicative of the measured voltage, and a control unit configured to output a first signal requesting the start of a charging process of the LFP, and when at least one of the voltage values of the multiple LFP cells outputted from the voltage measuring unit reaches a threshold voltage value while the charging process is performed by the first signal, output a second signal requesting the stop of the charging process and output a third signal requesting the start of a discharging process.
