摘要： A voltage measurement device includes: a plurality of voltage detection circuits which measure cell voltages of a plurality of cells connected in series. Each of the plurality of voltage detection circuits includes: a device address generating circuit which generates a device address according to a first address assignment command received from a preceding voltage detection circuit located at a preceding stage; and an address assignment command generating circuit which generates a second address assignment command according to the first address assignment command, and sends the second address assignment command to a next voltage detection circuit located at a next stage.

摘要： A voltage detection circuit is provided for measuring each cell voltage of an assembled battery configured by connecting a plurality of cells in series. The voltage detection circuit is defined as a first voltage detection circuit. The voltage detection circuit includes a downstream communication circuit that communicates with a host apparatus to communicate with a plurality of voltage detection circuits connected in series with each other; a reply signal generation circuit that generates a reply signal containing data detected by the first voltage detection circuit; an upstream transfer circuit that transfers a signal received by the upstream communication circuit to downstream; a dummy current consumption circuit that consumes a predetermined dummy current; and a control circuit that controls the reply signal generation circuit, the upstream transfer circuit, and the dummy current consumption circuit to selectively operate any one of them.
