1. A battery monitoring apparatus for monitoring a plurality of unit batteries of an assembled battery installed in a vehicle, the unit batteries of the assembled battery being grouped into a plurality of battery blocks,
the battery monitoring apparatus comprising:
a battery ECU;
a plurality of voltage monitors each of which is adapted to be mounted to a corresponding one of the battery blocks; and
a monitor activation device,
wherein
the battery ECU is configured to wirelessly transmit commands to the voltage monitors,
the voltage monitors are configured to detect voltage information of the unit batteries and wirelessly transmit the detected voltage information to the battery ECU, and
the monitor activation device is configured to sequentially activate the voltage monitors with time lags therebetween in a predetermined order recognized by the battery ECU,
wherein
the battery monitoring apparatus is configured so that:
the voltage monitors sequentially start wireless communication with the battery ECU in the predetermined order in which the voltage monitors are sequentially activated by the monitor activation device; and
the battery ECU assigns IDs, via the wireless communication, sequentially to the voltage monitors in the predetermined order.
