Resumen de: EP4708447A1
A battery ECU (300) calculates a gas generation amount (Vgo) generated in a case (S12), and calculates a gas permeation amount (Vgp) corresponding to an amount of leakage of the gas out of the case (S13). The battery ECU calculates an internal gas amount (Vg) that is a gas amount inside the battery, by subtracting the gas permeation amount (Vgp) from the gas generation amount (Vgo) (S14). Further, the battery ECU calculates an electrolyte solution permeation amount (Vep) corresponding to an amount of leakage of an electrolyte solution out of the case (S15), and calculates an internal void volume (Vc) that is a void volume inside the battery, by adding the electrolyte solution permeation amount (Vep) and an initial void volume (Vc0) (S16). Then, the battery ECU calculates a battery internal pressure (P) that is a pressure in the case, based on the internal gas amount (Vg) and the internal void volume (Vc) (S17).
