Zusammenfassung:	A method and power management assembly 10 for providing DC charging or discharging of an Electric Vehicle. The power management assembly is connected to a 3-phase AC power grid and to a DC charging port of the Electric Vehicle. It comprises power converters 20 that can be controlled to load the three phases of the AC grid individually to adjust for varying available capacity on each AC phase and/or unbalanced loads of the AC phases. The power management assembly 10 is a bidirectional charger in that it can also feed power from the battery of the Electric Vehicle to the AC grid and to control the current delivered to each phase individually to compensate for possible unbalanced phase loads.
