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 4):
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; and a fourth interface circuit for outputting the second voltage to the voltage measuring circuit through the third changeover switch and the fifth changeover switch, as well as outputting the third voltage to the voltage measuring circuit through the second changeover switch and the switch changeover switch.
