Energy efficiency and electrical safety of an electric vehicle charging station

Energy efficiency
Connecting equipment /power analyzers/ to the charging station without affecting its normal operation:
Connection before the charging station - alternating current (single-phase/three-phase) or direct current (from the public contact network).
Connection after the charging station - alternating or direct current, depending on the type of charging station.

Determining energy efficiency:
The input and output energy are measured from the initial charging value SOCmin to SOCmax. The charging duration is recorded and the ratio of output to input energy is calculated.

Registered quantities: Electrical energy and power through direct measurement of voltage and current.

Electrical Safety
Insulation control, protective earth resistance, circuit continuity and protective tripping parameters (including DC RCD).
