A bidirectional AC charging device is coupled to a mains supply and an electric vehicle, and includes a power transmission path, a switch, a first controller, a communication unit, and a second controller. One end of the power transmission path is coupled to the mains supply through the first connection end, and the other end is coupled to the electric vehicle through the second connection end. The switch is arranged on the power transmission path; the communication unit is coupled with the second connecting end; the first controller is coupled to the power transmission path, the switch, the second controller and the communication unit. When the second controller receives a power demand request, the first controller is notified, the first controller switches from the first signal to the second signal to communicate with the electric vehicle and controls the switch not to be conducted, and after receiving a feed permission notification provided by the electric vehicle, the first controller controls the switch to be conducted. The invention also relates to an operation method of the bidirectional AC charging device.
一种双向交流充电装置耦接市电与电动载具,且包括电力传输路径、开关、第一控制器、通信单元、及第二控制器。电力传输路径的一端通过第一连接端耦接市电,且另一端通过第二连接端耦接电动载具。开关被配置于电力传输路径上;通信单元耦接第二连接端;且第一控制器耦接电力传输路径、开关、第二控制器与通信单元。当第二控制器收到电力需求请求时通知第一控制器,第一控制器从第一信号切换为第二信号与电动载具通信并控制开关不导通,并于收到电动载具提供的允许馈电通知后,控制开关导通。本发明还涉及一种双向交流充电装置的操作方法。
