Protection and monitoring device in a charging infrastructure for charging electrically powered vehicles and methods for monitoring a charging infrastructure

摘要

The invention relates to a protection and monitoring device in a charging infrastructure for charging batteries of electrically powered vehicles, the protection and monitoring device comprising a protective conductor and at least one safety line loop (100) coupled to the at least one protective conductor, the at least one safety line loop (100 ) comprises at least a first integrated circuit (104), a second integrated circuit (106) and a number of switching elements (11_1, 11_2, 11_3, ..., 11_n), the switching elements (11_1, 11_2, 11_3, ... , 11_n) are each coupled to at least one monitoring unit that monitors at least one electrical component of the charging infrastructure. The present invention also relates to a corresponding method.
