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.
