The invention relates to the technical field of charging, in particular to an intelligent bidirectional charging pile which comprises a three-phase alternating-current power grid, a power frequency transformer, a filter, a bidirectional AC-DC converter set, a bidirectional DC-DC converter set, an electric vehicle storage battery set, a protection control unit and a battery voltage detection part.Two-way electric energy transmission can be achieved, an electric automobile can absorb energy from the power grid in the power consumption valley period and can also feed back the energy to the powergrid in the power consumption peak period, in this way, the daily power consumption load peak-valley difference can be effectively reduced, the power consumption requirement is balanced, the electricenergy is fully utilized, and waste is avoided.

    本发明涉及充电技术领域,尤其是涉及一种智能双向充电桩,其包括三相交流电网、工频变压器、滤波器、双向AC‑DC变换器组、双向DC‑DC变换器组、电动汽车蓄电池组、保护控制单元、电池电压检测部;本发明可以实现双向输送电能,电动汽车既可以在用电低谷期从电网中吸收能量,也可以在用电高峰期将能量回馈给电网,这样将能有效的减少日用电负荷峰谷差,平衡了用电需求,电能得到了充分利用,避免造成浪费。
