Abstract:
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.

Claim (Index 3):
The battery monitor according to  claim 2 , wherein the changeover switch group includes:\n a first changeover switch and a second changeover switch respectively connected between the first positive contact point and the interface circuit group; a third changeover switch connected between the second positive contact point and the interface circuit group; a fourth changeover switch and a fifth changeover switch respectively connected between the first negative contact point and the interface circuit group; and a sixth changeover switch connected between the second negative contact point and the interface circuit group, and wherein the interface circuit group includes: a first interface circuit for outputting the first voltage to the voltage measuring circuit through the first changeover switch and the fourth changeover switch; a second interface circuit for outputting the second voltage to the voltage measuring circuit through the third changeover switch and the fifth changeover switch; and a third interface circuit for outputting the third voltage to the voltage measuring circuit through the second changeover switch and the sixth changeover switch.
