Energy data, limit value monitoring and power quality in one device Awaiting the big eMobility breakthrough | MONITOR |1/2016 Connection of charging stations for electric vehicles Electromobility is gaining ground. It is not yet clear whenelectricitywillpower the majority of passenger vehi- cles. However, one thing is certain: at somepoint, almost every vehiclewillbepowered electrically. This will require a large number of suitable charging stations to charge these electric vehicles with power from the national grid. The comparatively high-power requirements of charging stations and the need to consider issues associatedwith 'simultaneity factors' present serious challenges to energy providers and grid distribution operators. Yet more aspects need to be taken into consideration when connecting charging stations to domestic networks to avoid risk to users or to the upstream electrical system. Depending on the electric vehiclemodel and the charging station used, charging procedures can be sub-divided into differentmodes. A key differentiating factor is the level of electrical power available (currently ranging from 3.7 kW to 22 kW). 56 1/2018 | MONITOR | Connection of an electric vehicle to theACmains power supply using a detachable charging line setwith vehicle coupling and anAC power supply installation.
