Bi-directional chargers supply AC/DC in one direction for charging and DC/AC (inverter) in the other direction. The typical bi-directional charger involves two power stages: an AC/DC power factor correction (PFC) stage and a DC/DC stage. Both stages must be bi-directional or additional converters will be required.
