The invention relates to an alternating current and direct current input energy storage charging system and a control method thereof. The system comprises a plurality of alternating current and direct current input energy storage charging devices, and an energy storage unit in the system is charged through an alternating current power supply input by an alternating current input end or a direct current power supply input by a direct current input end. After AC/DC or DC/DC conversion in the AC/DC double-input unit, the electric engineering vehicle is quickly charged, the system main controller monitors the state of each switch in the switching unit and controls the on-off of each switch to realize the switching of various working modes, and the system main controller is in communication connection with the AC/DC double-input unit and the energy storage unit; and the start and stop of the AC-DC dual-input unit and charging and discharging of the energy storage unit are controlled. According to the technical scheme provided by the invention, the problems that the charging time of the engineering vehicle is long and the charging site is far are solved, and the charging equipment can flexibly move along with the transfer of a construction site and has very high flexibility.

    本发明涉及一种交直流输入储能充电系统及其控制方法,该系统包括多个交直流输入储能充电装置,通过交流输入端输入的交流电源或直流输入端输入的直流电源对系统中的储能单元进行补电,通过交直流双输入单元中的AC/DC或DC/DC变换后对电动工程车进行快速补电,系统主控制器监测切换单元中各开关的状态,并控制各开关的通断,实现各种工作模式的切换,系统主控制器与交直流双输入单元和储能单元通过通讯连接,控制交直流双输入单元的启停及储能单元的充放电。本发明所提供的技术方案解决了工程车的充电时间长、补电地点远的问题,同时,该补电设备可以跟随施工现场的转移灵活移动,具有很高的灵活性。
