A battery monitoring device includes a first unit arranged outside a plurality of stacks each of which includes cells; a plurality of second units arranged in each of the stacks to output voltage data of the cells; a signal line that connects the second units and the first unit in a daisy chain mode; and a detection unit that detects a stack voltage wherein the first unit determines that a disconnection is generated on the signal line when a response is not received from the plurality of second units via the signal line after sending data is sent to the plurality of second units via the signal line and, determines on which path of the signal line, a forward path or a backward path, the disconnection is generated based on a difference between the stack voltage and a total of all detected output voltages sent from the second units. |
