The present disclosure discloses an on-board charger and an electric vehicle. The on-board charger includes a microprocessor and a DC module. A first sampling point is arranged between the DC module and a storage battery. A second sampling point is arranged between the storage battery and the microprocessor. The microprocessor is configured to: obtain a first voltage and a current value of the first sampling point, and obtain a second voltage of the second sampling point; and mark the connection between the storage battery and the DC module as cut off and record a first difference between the second voltage and the first voltage when the first voltage is greater than the second voltage and the current value is less than a preset current threshold.
