BATTERY SYSTEM

摘要

The present invention provides a battery system that is capable of transmitting the voltage value of each cell by means of wireless communication while suppressing costs and suppressing the number of components. The battery system 1 includes: cells 11a through 11d each having the positive electrode terminal 12P and the negative electrode terminal 12N; the voltage detection circuits 13 that detect the voltages of the cells 11a through 11d; the voltage detection lines 14 that connect each of the positive electrode terminal 12P and the negative electrode terminal 12N of the cells 11a through 11d to each voltage detection circuit 13; and the upper controller 31 that performs wireless communication with the voltage detection circuits 13 so as to receive, from each of the voltage detection circuits 13, the corresponding voltage of each cells 11a through 11d. The voltage detection line 14 functions as an antenna used to provide wireless communication between the voltage detection circuit 13 and the upper controller 31.
