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.

摘要： Communication distance can be extended in a battery system that transmits states of the battery cells by wireless communication. Each of cell controllers 100 wirelessly transmits measurement result of states of battery cells in cell groups 10 to a battery controller 200, by using an electric power supplied from the battery cells in the cell groups 10. The battery controller 200 continuously transmits unmodulated carrier wave to each of the cell controllers 100. Each of the cell controllers 100 changes an impedance for the unmodulated carrier wave transmitted from the battery controller 200 at a predetermined timing in dependence on the measurement result of the states of the battery cells in the cell groups 10. Due to this, the measurement result of the states of the battery cells in the cell groups 10 is wirelessly transmitted to the battery controller 200.
