Embodiment 1
[0031] figure 1 A schematic structural diagram of an embodiment of a supercapacitor fault detection device provided by the present invention. Such as figure 1 As shown, the supercapacitor fault detection device of the present embodiment may specifically include: an input filter circuit 11 for connecting the output interface of the supercapacitor detection signal and for performing supercapacitor fault diagnosis according to the historical output and current output of the input filter circuit 11 The processor circuit 12, the input filter circuit 11 is electrically connected with the processor circuit 12.
[0032] Specifically, the detection signal may specifically include an overvoltage detection signal, an overtemperature detection signal, and a polarity reverse detection signal. Assuming that the number of supercapacitors is 8, since each supercapacitor corresponds to one overvoltage detection signal, one overtemperature detection signal and one polarity reverse detection s...
Embodiment 2
[0037] figure 2 A schematic structural diagram of another embodiment of the supercapacitor fault detection device provided by the present invention. Such as figure 2 As shown, the supercapacitor fault detection device of this embodiment is in figure 1 On the basis of the supercapacitor fault detection device of the illustrated embodiment, it can also include: a communication interface circuit 24 for receiving the packaged data after the processor circuit 12 processes the supercapacitor detection signal, and the communication interface circuit 24 and the processor circuit 12 connection, also with the controller.
[0038]Specifically, after the processor circuit 12 generates detection results according to the current and previously received multi-channel detection signals, it can output the detection results such as alarm signals or normal state signals to the communication interface circuit 24, thereby sending them to the controller for control device for control processin...
