The invention provides a V2G charging pile. The V2G charging pile comprises an alternating current network, a PWM rectification module, a bidirectional DC/DC module and a central control unit. The alternating current network is electrically connected with the PWM rectification module, and the PWM rectification module is electrically connected with the bidirectional DC/DC module. The bidirectionalDC/DC module is electrically connected with an automobile storage battery, the PWM rectification module is used for rectifying side alternating current of the alternating current network so as to provide electric energy for a user load, boosted voltage is inverted into alternating current by the bidirectional DC/DC module via the PWM rectification module to enter the alternating current network during discharging, and the whole system is controlled by the central control unit in the charging process. According to the V2G charging pile, bidirectional flow of energy between the alternating current network and the automobile storage battery can be realized, so that the safety and stability of the alternating current network are greatly improved.
本发明提供一种V2G充电桩,包括交流电网、PWM整流模块、双向DC/DC模块以及中央控制单元,交流电网和PWM整流模块电性连接,PWM整流模块和双向DC/DC模块电性连接,双向DC/DC模块电性连接有汽车蓄电池,PWM整流模块用于对交流电网的侧交流电进行整流用以向用户负载提供电能,放电时双向DC/DC模块将升高后的电压经由PWM整流模块逆变成交流电进入交流电网,充电过程通过中央控制单元用以实现对整体系统的控制。本发明能够实现交流电网和汽车蓄电池之间能量的双向流动,从而大幅度提高了电网的安全性和稳定性。
