Claim 7:
8. The battery monitoring apparatus as set forth in claim 1, wherein the monitor activation device comprises the battery ECU and the voltage monitors,
each of the voltage monitors is configured to be activated, upon receipt of a predetermined activation signal, using electric power supplied from an electric power source other than the battery ECU,
the battery ECU is connected with a predetermined one of the voltage monitors via a signal line that transmits the activation signal, but neither the commands nor the voltage information,
all the voltage monitors are connected, via a plurality of connection lines that transmit the activation signal, in series with each other in the predetermined order from the predetermined voltage monitor, and
the battery monitoring apparatus is configured so that:
the battery ECU sends the activation signal to the predetermined voltage monitor via the signal line and thereby activates the predetermined voltage monitor; and then
the remaining voltage monitors are sequentially activated in the predetermined order through successive transmission of the activation signal from each activated one of the voltage monitors to another of the voltage monitors which is connected with the activated voltage monitor via a corresponding one of the connection lines and has not been activated yet.
