Title:
BATTERY CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/002440
Kind Code:
A1
Abstract:
Provided is a battery control device capable of obtaining an allowable charge/discharge current value that more accurately reflects the polarization state of a battery. A battery controller 101 is provided with: a first allowable current value calculation unit 704 for calculating, on the basis of the open circuit voltage OCV of a battery and the upper/lower limit voltages Vmax, Vmin set for the battery, a first allowable current value Imax1 that is the current limit value of the battery when assuming a non-polarized state; a battery equivalent circuit model 702 for estimating the polarized state of the battery when the current limit value is calculated; and a correction amount calculation unit 706 for calculating an allowable current value correction value ΔI for correcting the first allowable current value Imax1 on the basis of the assumed polarized state. The battery controller outputs, as the allowable charge/discharge current value of the battery, a second allowable current value Imax2 that is the corrected first allowable current value.
