Abstract

A battery system includes a plurality of battery modules and a control apparatus. The battery includes a battery group that includes two or more battery modules including battery units and battery monitoring units. The battery monitoring units of the battery modules being connected to each other via a communication line. The battery modules perform wired communication via the communication line. The battery group further includes a wireless receiving unit and a wireless transmitting unit. The wireless receiving unit wirelessly receives a command signal transmitted from the control apparatus. The wireless transmitting unit wirelessly transmits, to the control apparatus, a data signal including module identification information differing for each battery module. In the battery group, the wireless receiving unit is provided in a single battery module of the battery modules and the wireless transmitting unit is provided in a single battery module of the battery modules.
