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 1):
A battery monitor comprising:\n a voltage measuring circuit which measures voltages for detecting states of a positive side relay and a negative side relay connected between a positive terminal of a secondary battery and a load and between a negative terminal of the secondary battery and the load respectively; and an interface circuit group provided between the voltage measuring circuit and the positive side relay as well as the negative side relay, wherein the positive side relay makes or breaks continuity between a first positive contact point provided on a side toward the positive terminal of the secondary battery and a second positive contact point provided on a side toward the load, and the negative side relay makes or breaks continuity between a first negative contact point provided on a side toward the negative terminal of the secondary battery and a second negative contact point provided on a side toward the load, and wherein the voltage measuring circuit can measure a first voltage between the first positive contact point and the first negative contact point, a second voltage between the second positive contact point and the first negative contact point, and a third voltage between the first positive contact point and the second negative contact point, through the interface circuit group, detects the state of the positive side relay based on measurement results of the first voltage and the second voltage when the first voltage and the second voltage are measured in synchronization with each other, and detects the state of the negative side relay based on measurement results of the first voltage and the third voltage when the first voltage and the third voltage are measured in synchronization with each other.
