非车载传导式充电机与电动汽车之间的数字通信协议版本分析OA

With the increasing demand for new charging methods such as high-power charging,scheduled charging,as well as plug and charge,the new energy vehicle industry is experiencing a wave of technological innovation.The abolition of GB/T 27930-2015 and the successive release of GB/T 27930-2023 and GB/T 27930.2-2024 mark the completion of the update of the communication protocol between off-board conductive chargers and electric vehicles,officially entering the transitional period for market selection.At this stage,it is particularly important to understand and master the connections and differences among various versions of communication protocols.This paper mainly elaborates on the similarities and differences among the three versions of communication protocol standards,GB/T 27930-2015,GB/T 27930-2023 and GB/T 27930.2-2024 from aspects such as message definition and content requirements.
