摘　　要：近些年,随着欧洲新能源电动汽车领域的发展,国际标准化组织制定了ISO 15118系列通信标准,该标准对车-桩通信交互进行了定义。EXI格式作为协议底层传输的载体,在通信过程中,用以实现在受限线路上进行高效传输。文章通过描述通信标准中定义的数据结构的解析方法,获取事件码与元素层级结构。通过采用递归模型,逐步完成对复杂元素的深入,由复杂元素转变为多个简单元素,并通过完成简单元素的编解码,从而实现整个通信消息的编解码。最后通过EXI编解码测试验证设计结果。In recent years,with the development of new energy electric vehicles in Europe,the International Organization for Standardization has formulated ISO15118 series communication standards.As the carrier of the underlying transmission format,EXI is more efficiently and extensibility than traditional XML format on a restricted channel.This paper describes the design of the analytic method for the data structure defined in the communication standard to obtain the event code and element hierarchy.By adopting recursive model,the complex elements are gradually transformed into simple elements,and the codecs of simple elements are completed to realize the codecs of the whole communication message.And finally,the design results are verified by EXI codec test.
