Abstract
A battery monitoring apparatus is provided for monitoring unit batteries of an assembled battery which are grouped into battery blocks. The battery monitoring apparatus includes a battery ECU, voltage monitors each being mounted to a corresponding one of the battery blocks, and a monitor activation device. 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. The monitor activation device is configured to sequentially activate the voltage monitors with time lags in a predetermined order recognized by the battery ECU. Moreover, the battery monitoring apparatus is configured so that: the voltage monitors sequentially start wireless communication with the battery ECU in the predetermined order; and the battery ECU assigns IDs, via the wireless communication, sequentially to the voltage monitors in the predetermined order.
