A battery monitoring system includes a plurality of battery monitoring devices that are connected to a battery formed by connecting a plurality of battery cell groups in series to each other, and monitor a state of the battery for the respective battery cell groups, each of the plurality of battery cell groups being formed by one or a plurality of battery cells connected in series, and a host controller that performs wireless communication with the plurality of battery monitoring devices. First identification information pieces which are different from each other are set in the plurality of battery monitoring devices in advance, and second identification information corresponding to an order of potentials of the battery cell groups in the battery, to which the battery monitoring devices are connected, is assigned to each of the plurality of battery monitoring devices. In addition, the host controller stores a correspondence relationship between the first identification information and the second identification information for each of the plurality of battery monitoring devices.
