Abstract

A voltage detection circuit includes a first terminal for connecting to one end of a first voltage detection line through a first resistor, the first voltage detection line having another end connected to a cathode or an anode of a first individual battery; a second terminal for connecting to the one end of the first voltage detection line without the first resistor; a first current generating circuit connected to the first terminal; and a voltage detector which detects a voltage of the first terminal and a voltage of the second terminal. The voltage detector includes at least one first AD converter connected to the first terminal, and at least one second AD converter connected to the second terminal.
