A bidirectional on-board charger (10) includes a direct current bus (100), two bus capacitors, a power factor correction circuit (101), and a controller (102). The power factor correction circuit includes (101): a first bridge arm (1011), connected in series between a positive electrode and a negative electrode of the direct current bus (100), where a midpoint of the first bridge arm (1011) is connected to a series connection point of the two bus capacitors through a first switch (K1); and three second bridge arms, separately connected in series between the positive electrode and the negative electrode of the direct current bus (100). The controller (102) is configured to: control the first switch (K1) to be turned off, and control at least one of the second bridge arms to output a direct current to charge a power battery (12); or control the first switch (K1) to be turned on, and control a midpoint of at least one of the second bridge arms to output an alternating current to supply power to an alternating current load (13). AnVehicle power system and an electric vehicle are further disclosed. The charger is compatible with a forward charging function of charging the power battery and a reverse discharging function of supplying power to the alternating current load, thereby greatly reducing circuit costs. Therefore, operational flexibility is high, and applicability is high.
