The invention relates to the technical field of electric vehicle charging, in particular to a charging and discharging device and a charging and discharging system.The charging and discharging device comprises a charging gun, an alternating current power board, an inverter and a first charging and discharging controller. An alternating current charging interface is introduced on the basis of a direct current charging gun of an existing CCS charging system, and an alternating current loop and a direct current loop are integrated, so that the charging and discharging device can utilize an alternating current power board to supply power to a vehicle-mounted charger of an electric vehicle to realize an alternating current charging function; the inverter is utilized to invert the direct current of the power battery of the electric vehicle into the alternating current to realize an external discharging function, so that the cost of the bidirectional charging and discharging system between the vehicle and the pile is better, and the inverter can support mutual switching between an off-grid mode and a grid-connected mode.
