The invention discloses a communication control method for realizing bicycle-pile interaction based on international AC charging pile supplementation, and the method employs an existing CP original function module, an electronic switch Sv, an electronic switch Sc, and a single-line bidirectional communication electrical interface. Interaction between an alternating-current ordered V2G charging pile and a vehicle simulation test verification device is achieved, an electronic switch Sv is added to the upper vehicle end on the basis of an original design, an electronic switch Sc is added to the pile end, a + 12V pull-up resistor R1 is utilized, a single-line two-way communication electrical interface is established, a carrier signal is simulated through a CC/CP port in a national standard alternating-current charging port to conduct information transmission, and the alternating-current ordered V2G charging pile and the vehicle simulation test verification device are integrated. After the vehicle is connected with the pile, the CC/CP port of the pile sends a handshake signal to the vehicle-mounted charger and waits for reply of the vehicle end so as to confirm whether the vehicle supports alternating current V2G, if the vehicle is a V2G vehicle type, a V2G vehicle pile interactive communication protocol is started, charging and dispatching discharging can be carried out, and if the vehicle is a non-V2G vehicle type, charging can only be carried out according to the national standard charging process, and discharging cannot be carried out.
本发明公开一种基于国际交流充电桩补充实现车桩交互的通讯控制方法,所述车桩交互的通讯控制方法包括现有CP原有功能模块、电子开关Sv、电子开关Sc和单线双向通讯电气接口,本发明实现交流有序V2G充电桩和车辆模拟测试验证设备之间的交互,在原有设计基础上车端增加电子开关Sv,桩端增加电子开关Sc,利用+12V上拉电阻R1,建立单线双向通讯电气接口,国标交流充电口中,采用CC/CP口模拟一个载波信号进行信息传递,车与桩连接后,桩的CC/CP口向车载充电机发送一个握手信号,等待车端回复,从而确认该车是否支持交流V2G,如果是V2G车型,就开启V2G车桩互动通信规约,可以充电和调度放电,如果是非V2G车型,就仅能按国标充电流程进行充电,不能放电。
