Provided are an on-board charger and an electric vehicle. The on-board charger comprises a microprocessor (4) and a DC module (2); a first sampling point (A1) is provided between the DC module (2) and a storage battery (3); a second sampling point (A2) is provided between the storage battery (3) and the microprocessor (4); the microprocessor (4) is configured to: obtain a first voltage value and a current value at the first sampling point (A1), and obtain a second voltage value at the second sampling point (A2); and when the first voltage value is greater than the second voltage value, and the current value is less than a preset current threshold, mark that the storage battery (3) is disconnected from the DC module (2), and record a first difference between the second voltage value and the first voltage value.
