Description
Summary:In this paper, a kind of fuel cell voltage monitoring (CVM) system with negative voltage direct detection function is proposed for the reverse polarity phenomenon of fuel cell stack. This system uses optocoupler relays array to realize sampling channel switching and negative voltage conversion. The CVM prototype shows that the voltage measurement range of the proposed system is larger than that of the superimposed bias voltage method, and the sampling accuracy of cell voltage is 3mV.
