Analysis of the functional and electrical safety of charging stations

  • The number of public charging stations for electric vehicles is rising. It's estimated that in 2014 more than 1.000.000 public charging stations will be installed worldwide. Currently there is no specific standard for Functional Safety and the standard for Electrical Safety is derived from standards for similar systems. The intent of this paper is to examine the existing safety architecture of mode 3 charging stations. First the standards for the charging process and the different modes are presented. Then a standard architecture for a mode 3 charging station, based on the IEC 61841, is described. After that a risk analysis of this model is performed and the electrical and Functional Safety of the architecture are analyzed. Both analyses are based on the general safety standards VDE 0100 and IEC 61508. After that possibilities for improvements and future challenges with Mode 4 charging are discussed.
