摘要： As an SOHQ calculation method, a method for calculating a full charge capacity based on SOCv of two points and a current integration value between the two points has been known, but accuracy of the SOHQ is lowered due to various error factors such as an OCV estimation error. A battery control device includes: an SOHQ calculation unit which calculates SOHQ based on a value including a current value and/or a voltage value of the battery; a threshold value determination unit which determines an SOHQ threshold value based on an internal resistance of the battery; and an SOHQ determination unit which determines the SOHQ based on a comparison between the SOHQ calculated by the SOHQ calculation unit and the SOHQ threshold value.

摘要： An object of the present invention is to provide a battery control device capable of obtaining an allowable charge/discharge current value further accurately reflecting a polarization state of a battery. A battery controller 101 includes a first allowable current value calculation unit 704, a battery equivalent circuit model 702, and a correction amount calculation unit 706t. The first allowable current value calculation unit calculates a first allowable current value Imax1 which is a current limit value of a battery assuming a non-polarization state, based on an open circuit voltage OCV of the battery and upper and lower limit voltages Vmax and Vmin set in the battery. The battery equivalent circuit model 702 estimates a polarization state of the battery at the time of calculating the current limit value. The correction amount calculation unit 706t calculates an allowable current value correction value ΔI for correcting the first allowable current value Imax1 based on the estimated polarization state. The second allowable current value Imax2 which is the corrected first allowable current value is output as an allowable charge/discharge current value of the battery.
