The invention discloses a charging interaction method, a charging interaction device, a charging pile, an electric vehicle and a vehicle pile interaction system. The charging interaction method is applied to a charging pile controller and comprises the steps of: converting first interaction information into a first optical signal when the charging pile is connected with the electric vehicle, and transmitting the first optical signal to the electric vehicle, thus enabling the electric vehicle to acquire first interaction information based on the first optical signal, and/or receiving a second optical signal sent by the electric vehicle and converting the second optical signal into second interaction information. According to the invention, since the charging pile communicates with the electric vehicle in an optical signal transmission mode, photoelectric isolation is realized, and electromagnetic interference in the charging process is avoided, reliable interaction of interaction information between the charging pile and the electric vehicle can be ensured, the technical problem that in the prior art, non-charging necessary information cannot be directly transmitted between an electric vehicle and a charging pile, and consequently deep interaction cannot be conducted between the automobile and the charging pile is solved.

    本发明公开了一种充电交互方法、充电交互装置、充电桩、电动汽车和车桩交互系统,充电交互方法应用于充电桩控制器,包括:当充电桩与电动汽车连接时,将第一交互信息转化成第一光信号后传送给电动汽车,以使电动汽车基于第一光信号得到第一交互信息,和/或接收电动汽车发送的第二光信号并转化成第二交互信息。本申请中,由于充电桩与电动汽车之间通过光信号传输的方式进行通信,实现了光电隔离,避免了充电过程中的电磁干扰,因此,本申请能够保证交互信息在充电桩与电动汽车之间进行可靠地交互,解决了现有技术中非充电必要信息无法在电动汽车与充电桩之间直接传输,致使车、桩之间无法进行深度交互的技术问题。
