STANDARDS-COMPLIANT TESTING OF DC CHARGING POINTS:DIAGNOSIS OF THE CHARGING INFRASTRUCTURE AND PERFORMANCE OF REQUIRED MEASUREMENTS AND FUNCTION TESTS
■Electromobility without restrictions is the goal when buying an electric vehicle - guaranteed mobility and flexibility by means of fast DC charging and its undesired dependence on the charging system and charging point equipment.
■But what does fast charging mean and how safe is it for the user?
▲Charging with direct current always necessitates a connection between the electric vehicle and the charging point via a permanently connected charging cable. Cable-based charging of electric vehicles (EVs), also known as conductive charging, is possible in various charging modes which are defined in system standard DIN EN 61851 -1 (VDE 0122-1). Charging mode 4 is specified for charging with direct current (DC charging) at permanently installed charging stations. This special DC charging infrastructure ensures high levels of electrical safety, as well as overload protection for the installation, e.g. fire protection. Further protection against touching and tampering is provided by locking the charging plug connection during the charging process. Communication and control for the charging process is handled by a special communication interface.
The interface between the vehicle and the charging point is a decisive criterion for safe and convenient use of the charging infrastructure.
