Abstract
A battery monitoring system includes a multiplexer, a self-diagnosis voltage generation circuit, a first voltage measuring circuit and a voltage measuring circuit which measure voltage signals in a first route and a second route inputted through the multiplexer, based on the self-diagnosis voltage generated from the self-diagnosis voltage generation circuit or based on the voltages of battery cells outputted from the input circuit, a comparator which compares measurement results of the first and second voltage measuring circuits, and a control unit which judges the presence/absence of a failure in a measuring route connected to the first voltage measuring circuit or the second voltage measuring circuit and the presence/absence of a failure of the first voltage measuring circuit itself or the second voltage measuring circuit itself, based on a comparison result by the comparator and which controls the input circuit, the multiplexer, the comparator, and the self-diagnosis voltage generation circuit.
