The invention relates to an alternating current charging pile V2G system and a control method thereof, and belongs to the technical field of electric vehicles. The system comprises a plurality of charging and discharging piles, and each charging and discharging pile comprises a charging loop and an electricity selling loop which are connected to an alternating current power grid. The control unit of the charging and discharging pile can selectively connect the charging loop or the electricity selling loop with the electric vehicle through the bidirectional electric gun according to the setting of a user or the control of the charging and discharging management platform, so that the charging and discharging pile works in a charging state of charging the electric vehicle or an electricity selling state of discharging the electric vehicle to an alternating current power grid. In an electricity selling state, electric power can be effectively transmitted to a power grid, and the frequency of the alternating-current power grid is stabilized. Compared with a direct-current charging V2G, the alternating-current charging pile V2G system adopted by the invention is lower in construction, operation and maintenance cost, smaller in damage to a battery of the new energy automobile, and suitable for alternating-current charging pile networks of various scales.

    本发明涉及一种交流充电桩V2G系统及其控制方法,属于电动汽车技术领域。该系统包括若干个充放电桩,每个所述的充放电桩均包括连接于交流电网的充电回路和售电回路,充放电桩的控制单元可以根据用户的设定或者根据充放电管理平台的控制选择性地将充电回路或者售电回路通过双向电枪连接电动汽车,以使该充放电桩工作于向电动汽车充电的充电状态或者电动汽车向交流电网放电的售电状态。在售电状态下,能够有效地向电网输送电力,稳定交流电网频率。且相较于直流充电V2G,本发明采用的交流充电桩V2G系统的建设、运营和维护成本更低,对新能源汽车电池的损害更小,适用于各种不同规模的交流充电桩网络。
