The invention discloses a bidirectional AC/DC and unidirectional DC mixed charging pile and an inversion discharging method. The charging pile comprises a control system and a charging module; the charging module is communicated with the control system through a CAN bus, and the charging module comprises a plurality of one-way direct current modules and a plurality of two-way alternating current and direct current modules; every two bidirectional AC/DC modules form a group, and the power of a single bidirectional AC/DC module is half of the power of the unidirectional DC module. The bidirectional AC/DC module and the unidirectional DC module are connected in parallel with the CAN bus. The input end of the charging module is connected with an EPS and an emergency load, and the output end of the charging module is connected with a plurality of charging guns. A traditional one-way direct current module is matched with a two-way alternating current and direct current module for mixed matching control, the expanded charging pile can only charge a vehicle singly, the function of reverse discharging of a new energy vehicle through the charging pile is achieved, the V2L discharging function is achieved, the equipment function is expanded while the equipment cost is saved, and the charging efficiency is improved. And the resource utilization rate of the infrastructure of the charging pile is greatly improved.
本发明公开了一种双向交直流与单向直流混搭的充电桩及逆变放电方法,包括控制系统和充电模组;充电模组采用CAN总线与控制系统连通,充电模组包括多个单向直流模块和若干个双向交直流模块;双向交直流模块两两为一组,单个双向交直流模块的功率为单向直流模块功率的二分之一;双向交直流模块与单向直流模块均并连在CAN总线上;充电模组输入端连接有EPS和应急负载,充电模组输出端连接有多个充电枪。本发明将传统单向直流模块搭配双向交直流模块的混搭控制,拓展充电桩只能单一对车充电功能,具备新能源车通过充电桩逆向放电功能,实现了V2L放电功能,节省设备成本的同时扩展了设备功能,大大提升了充电桩这一基础设施的资源利用率。
