The invention relates to the technical field of electric vehicle charging, in particular to an electric vehicle charging system and method, communication and positioning of a charging station end and a vehicle end are achieved based on a Beidou satellite system, and interaction data of a Beidou communication positioning end, the vehicle end and the charging station end are signed through digital signatures. According to the invention, the electric vehicle and the charging station can be in communication connection by using the Beidou system short message in the scene of no internet signal or poor internet signal, the identity of an information sender and the authenticity and integrity of the sent information are ensured, the information is prevented from being illegally tampered, and the safety of the electric vehicle is improved. And a timestamp and a random number are further applied to the sent information, so that the information is prevented from being replayed and attacked, the safety of the information is ensured, and the charging of the electric vehicle is safe, reliable, simple and efficient.

    本发明涉及电动车充电技术领域,特别涉及一种电动汽车充电系统及方法,基于北斗卫星系统实现充电站端和车端的通信及定位,并利用数字签名对北斗通信定位端、车端和充电站端的交互数据进行签名。本发明能够在没有互联网络信号或者互联网络信号不佳的场景下,使得电动汽车与充电站之间能够利用北斗系统短报文进行通信连接,且保证信息发送方的身份及所发信息的真实和完整性,防止信息被非法篡改,并进一步在发送的信息中应用时间戳和随机数,防止信息被重放攻击,保证信息的安全,使得电动汽车充电既安全可靠、有简单高效。
