Abstract
The present invention provides a voltage acquisition circuit. The voltage acquisition circuit includes a voltage division and sampling module, a voltage to frequency conversion module, and an isolation module. The voltage to frequency conversion module is electrically coupled to the voltage division and sampling module and the isolation module. The voltage division and sampling module is configured to divide and sample a total voltage of a battery pack, and output a voltage signal to the voltage to frequency conversion module. The voltage to frequency conversion module is configured to convert the voltage signal into a first frequency signal, and output the first frequency signal to the isolation module. The isolation module is configured to electrically isolate the first frequency signal, to generate a second frequency signal. The present invention further provides an electric vehicle with the voltage acquisition circuit.
