Abstract
It is preferable to measure a voltage difference between two electric storage cells with a higher precision while suppressing costs of a balance correction circuit. A balance correction apparatus comprises a first balance correction section which equalizes voltages of two electric storage cells among a plurality of electric storage cells connected in series, a second balance correction section which equalizes voltages of two electric storage cells among the plurality of electric storage cells and a control section which controls operations of the first balance correction section and the second balance correction section. The control section generates a first control signal which controls operations of the first balance correction section and a second control signal which controls operations of the second balance correction section based on a measurement result of each voltage of the plurality of electric storage cells.
