Classification: CPC H  G  Y | IPC G  H

Claim 0:
1. A battery system comprising a plurality of battery modules, each of the battery modules comprising:
an assembled battery that includes a plurality of battery cells connected in series;
a monitoring unit configured to monitor the assembled battery; and
a plurality of temperature sensors electrically connected to the monitoring unit by a plurality of wirings,
the monitoring unit of each of the battery modules comprising:
a connector that includes a plurality of terminals that are connected to the plurality of electric wirings extending from the plurality of temperature sensors, a number of the plurality of terminals of the connector being greater than a number of the plurality of temperature sensors so that at least one of the plurality of terminals is not connected to a wiring and is thus an unused terminal,
the plurality of temperature sensors being configured to output voltage signals indicative of temperatures of the assembled battery to the respective terminals of the connector;
a generation unit configured to generate, based on the voltage signals input to the respective terminals from the plurality of temperature sensors, an identification information item on the corresponding one of the battery modules; and
an input processing unit configured to:
perform input processing on the voltage signals outputted from the plurality of temperature sensors with a predetermined voltage range; and
cause a voltage at the unused terminal to be outside the predetermined voltage range,

a position of the unused terminal relative to the other terminals of the plurality of terminals of the connector being different for each of the plurality of battery modules, and
the identification information items of the respective battery modules being different from one another.
