A charging and discharging switching apparatus (200) and method, and a bidirectional charging system are provided. The charging and discharging switching apparatus (200) mainly includes a first switch (K1), a second switch (K2), a switching power supply (B), and a control unit (201). A first end of the first switch (K1) is configured to connect to a power supply device (400), a second end of the first switch (K1) is configured to connect to a load device (300), and the second end of the first switch (K1) is further separately connected to a first end of the second switch (K2) and the switching power supply (B). A second end of the second switch (K2) is configured to connect to a new energy vehicle (100). After a first condition is met, the control unit (201) controls the switching power supply (B) to discharge, and turns on the second switch (K2), to conduct a path through which the new energy vehicle (100) supplies power to the load device (300). After a second condition is met, the control unit (201) turns on the first switch (K1), to conduct a path through which the power supply device (400) supplies power to the load device (300). The use of the charging power switching apparatus (200) helps shorten power interruption time of the load device (300).
