The invention discloses an electric vehicle alternating-current charging interface communication device, which comprises a charging pile end plug located at a charging pile end and a charging pile endsocket located at a vehicle end, wherein both the charging plug and the charging socket are internally provided with an induction communication coil, and a modulation and demodulation circuit and anencryption and decryption communication chip for communication. According to the invention, a high-speed and reliable communication solution is provided for an electric vehicle alternating-current charging interface, and the limitation that traditional PWM communication between a charging pile and a vehicle cannot transmit charging data is solved, so that the charging pile can obtain detailed information such as a battery, the charging voltage, the current, the temperature and alarm of the vehicle before charging is started and in the charging process, and the charging can be controlled more reliably. Meanwhile, the communication between the plug and the socket is non-contact coupling communication, thereby avoiding electrical contact, and enabling the communication to be safer and more reliable.
本发明公开了一种电动汽车交流充电接口通信装置,包括位于充电桩端的充电桩端插头,以及位于车辆端的充电桩端插座;充电插头及充电插座均内置感应通信线圈,以及用于通信的调制解调电路和加解密通信芯片;本发明为电动汽车交流充电接口提供了一个高速可靠的通信解决方案,解决了充电桩与车辆之间传统的PWM通信无法传递充电数据的局限,使得充电桩在启动充电前以及充电过程中能够获取到车辆详细的电池、充电电压、电流、温度以及报警等信息,从而能够更为可靠的控制充电;同时插头与插座之间的通信为非接触式耦合通信,避免了电气接触,使得通信更加安全可靠。
