    Abstract: A bipolar LFP battery includes a plurality of cells that are stacked together. A positive electrode active material layer of each of the cells includes lithium iron phosphate. A ?Q calculation unit calculates an increase ?Q of a charge amount, during charging of the cell of the bipolar LFP battery. The increase ?Q is an increase in the charge amount of the cell when the voltage of the cell increases from a first voltage to a second voltage. A full charge capacity estimation unit uses a full charge capacity map to estimate the full charge capacity of the cell, using the increase ?Q of the charge amount as a parameter.
