The invention discloses a non-vehicle-borne bidirectional rectifier DC charger which comprises a charging module which comprises an AC distribution power supply unit, an isolation transformer, a filtering module, a boost reactor and a power unit connected in order. The power unit is externally provided with a charging output unit and an energy storage battery group which are connected to the power unit. The charging module is externally provided with a control module for controlling the operation of the charging module. The control module is connected to the AC distribution power supply unit and the power unit. Compared with the prior art, the use rate of a charging pile is improved, the volatility reduction of a grid is realized through feeding stored energy to the grid, the electric energy quality is improved, and the effect of energy saving is obvious.
