Grid as Backbone for E-Mobility

Technical Connection Rules for low voltage (VDE-AR-N 4100)

All relevant actors – from network operators, manufacturers of charging infrastructure, vehicles and measurement technology to certification bodies and scientific institutions – work together at VDE FNN to create technical rules for a successful grid integration of the new mobility. A development which requires foresight from all involved, to avoid expensive corrections later on.

With the Technical Connection Rule for low voltage (VDE-AR-N 4100), VDE FNN showcases important developments in the field of charging equipment for E-Mobility and energy storage. Requirements are also described for the integration of increasing number of electric cars into the low voltage networks.

In a nutshell

• Mandatory registration of all charging devices,
• Network-supportive behaviour of charging devices, e.g. possibility for reactive power control,
• Connection conditions for switch and control cabinets, meter connection stations and telecommunications systems,
• Technical design for network connection layouts and meter panels housing measuring and control equipment.
