Abstract
A voltage detection apparatus includes a plurality of voltage detection units, each of which detects cell voltages of plural cells in each of blocks in a battery module. Each of blocks includes the plural cells connected in series. The plurality of voltage detection units are respectively supplied with power via power supply lines connected to the blocks. The plurality of voltage detection units are respectively provided with a plurality of current increase units for increasing dark currents so that the dark currents flowing through the power supply lines respectively become a same target value.
