BATTERY SYSTEM
Document Type and Number:
Japanese Patent JP2018116884
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a battery system comprising a laminate type battery, capable of improving estimation accuracy of an inner resistance of the laminate type battery.SOLUTION: A battery system 90 includes a bipolar battery 1 and an ECU 100. The bipolar battery 1 includes a plurality of battery cells 10 in which a positive electrode plate 43 and a negative electrode plate 45 are laminated in a lamination direction Z through a separator 43. The ECU 100 is constructed so as to calculate an inner resistance R1 of a region from a temperature in each of a plurality of regions X1 to X10 obtained by virtually dividing the battery cells 10 along the laminate direction Z, and estimate the inner part resistance of each battery cell 10 by synthesizing an inner resistance R2 of the plurality of regions to be calculated.SELECTED DRAWING: Figure 7
