  • Patent number: 11220185
    Abstract: A battery monitoring device includes temperature detectors that detect respective temperatures of battery elements in a battery of an electric vehicle. The temperature detectors each include first and second detection circuits, a comparator circuit, and first and second output terminals. The first detection circuit detects a temperature in a first temperature range and generates a first detection signal. The second detection circuit detects a temperature in a second temperature range and generates a second detection signal. The comparator circuit compares a detection output signal with a threshold and generates a flag signal indicative of the presence or absence of an abnormal event. The detection output signal and the flag signal are outputted through a first output terminal and a second output terminal, respectively. Each of the temperature detectors switches the detection output signal between the first detection signal and the second detection signal on the basis of the flag signal.
