The invention provides an electric car charging shifting device and method. The electric car charging shifting device is applied to electric cars with rapid charging sockets and slow charging sockets.The electric car charging shifting device comprises a first charging guide circuit connected with the rapid charging socket, a second charging guide circuit connected with the slow charging socket, and a third charging guide circuit connected with the rapid charging socket and the slow charging socket; the CC2 signal end of the rapid charging socket is connected with the input end of the first charging guide circuit; the CC signal end of the slow charging socket is connected with the input end of the second charging guide circuit; the CC1 signal end of the rapid charging socket and the CP signal end of the slow charging socket are connected with the third charging guide circuit respectively; and the type of a charging gun head is determined through the first charging guide circuit connected with the rapid charging socket and the second charging guide circuit connected with the slow charging socket, and the situation that when the rapid charging socket and the slow charging socket areboth connected with the charging gun heads, the same module cannot accurately judge the type of the charging gun heads, and thus charging is abnormal.
Description
technical field [0001] The invention relates to the field of electric vehicle charging, in particular to an electric vehicle charging switching device and method. Background technique [0002] With the increasing number of automobiles and the increasingly serious environmental pollution, the development of electric vehicles has attracted more and more attention. Among them, the charging technology of electric vehicles has become the key technology for the rapid development of electric vehicles. [0003] Usually electric vehicles are equipped with a fast charging stand and a slow charging stand, and users can freely choose which charging stand to use for charging according to the type of charging pile. However, if the user accidentally inserts a charging tip into the fast charging stand and the slow charging stand, this will cause a misjudgment of the resistance of the charging tip, resulting in abnormal charging. Contents of the invention [0004] The invention provides ...
