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.

摘要： The present invention enables correct detection of the state of a relay provided on each of the positive and negative terminal sides of a secondary battery. A positive-side main relay 12 makes or breaks continuity between first and second positive contact points, and a negative-side main relay 15 makes or breaks continuity between first and second negative contact points. A microcomputer 2 can measure a first voltage between the first positive and first negative contact points, a second voltage between the second positive and first negative contact points, and a third voltage between the first positive and second negative contact points. The microcomputer 2 detects the state of the positive-side main relay 12 based on a voltage measurement result obtained when the first and second voltages are measured synchronously, and detects the state of the negative-side main relay 15 based on a voltage measurement result obtained when the first and third voltages are measured synchronously.
