Abstract

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.

Description

technical field [0001] The invention relates to a charging device, in particular to an off-vehicle bidirectional rectifying DC charger, which belongs to the field of electronic circuits. Background technique [0002] At present, the DC chargers for non-vehicle electric vehicles widely used in the market, their core components use a one-way rectification module, and the electric energy only flows from the grid to the vehicle battery. Energy saving and benefit, is a waste of resources. [0003] For example, the application number is 201310048799.7, a charging station used when charging electric vehicles. A charging station and related method for use in charging an electrically powered vehicle are disclosed. An exemplary charging station (10) includes: a housing (12) defining an interior (14) and an opening (18) configured to allow access to the interior; a door (20) configured to substantially cover the opening; and a hinge assembly ( 22) configured to provide pivotal movem...
