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 makes or breaks continuity between first and second positive contact points, and a negative-side main relay makes or breaks continuity between first and second negative contact points. A microcomputer 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 detects the state of the positive-side main relay 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 based on a voltage measurement result obtained when the first and third voltages are measured synchronously.
