摘要：PROBLEM TO BE SOLVED: To provide a battery control device capable ofobtaining an allowable charge/discharge current value that reflects the polarized stateof a battery more accurately.SOLUTION: A battery control device includes a calculationsection to calculate a value of the maximum current that can be supplied to a battery,and a storage section. The calculation section includes a battery equivalent circuit modelpart to calculate the current polarization voltage of a battery by using information ofeach of a current value, voltage value and temperature of the battery, and the storagesection stores parameters representing the time change of a polarizationvoltage.SELECTED DRAWING: Figure 2
