The invention discloses a bidirectional charging pile and a charging and discharging system, and belongs to the technical field of power management. The bidirectional charging pile and the charging and discharging system comprise a main power loop. A first auxiliary power supply circuit configured to convert a power supply at a power grid side into a first power supply; a second auxiliary power supply circuit configured to convert the power supply at the charging side into a second power supply; and the system power supply circuit is configured to use the first power supply or the second power supply to provide power required by the operation of the bidirectional charging pile. When the bidirectional charging pile and the charging and discharging system perform forward charging, the first auxiliary power supply circuit provides a first power supply for the system power supply circuit by using the electric energy of the power grid side of the main power loop, and the system power supply circuit provides a power supply for forward operation of the bidirectional charging pile and the charging and discharging system; and when the power grid is abnormally powered off, the second auxiliary power supply circuit provides a second power supply for the system power supply circuit by using the electric energy of the electric automobile, and the system power supply circuit provides power for reverse operation of the bidirectional charging pile and the charging and discharging system by using the second power supply.
