The invention discloses a plug-and-play charging instant decoding method and a plug-and-play charging instant decoding device for an automobile. The method comprises the steps that a CODE code is created based on a CODE code request of a charging pile and returned to the charging pile, the charging pile forms a PWM data packet corresponding to the CODE code based on a CODE code coding rule and sends the PWM data packet at least once according to a guide time sequence, and the PWM data packet comprises a sending identifier, a packet header, two manufacturer codes and five bicycle pile verification random codes; wherein the sending identifier, the packet header, each manufacturer code and each bicycle pile verification random code respectively correspond to a section of PWM wave signal; and receiving each section of PWM wave signal of the PWM data packet one by one, and identifying and analyzing each section of PWM wave signal in the PWM data packet one by one based on a state machine jump mode in the receiving process to obtain a complete CODE code corresponding to the PWM data packet. According to the method, on the basis of CODE time sequence and instant decoding requirements, code development is carried out through state machine skipping, and instant decoding can be achieved.
本发明公开了一种汽车即插即充的充电即时解码方法及装置。该方法包括:基于充电桩的CODE码请求创建CODE码并返回给充电桩,充电桩基于CODE码编码规则形成与CODE码对应的PWM数据包,并按照引导时序发送PWM数据包至少一次,其中PWM数据包包含:发送标识、包头、两位厂家编码及五位车桩校验随机码,其中发送标识、包头、每一位厂家编码以及每一位车桩校验随机码分别对应一段PWM波信号;逐一接收PWM数据包的每一段PWM波信号,在接收过程中基于状态机跳转的方式对PWM数据包中的每段PWM波信号逐一进行识别和解析,得到PWM数据包对应的完整CODE码。该方法基于CODE时序和即时解码的要求,状态机跳转进行代码开发,可实现即时解码。
