The establishment of charging stations is regulated by DSB’s regulations on low-voltage electrical installations (FEL) and the standard NEK 400 Electrical low-voltage installations, which the regulations refer to as a method. NEK 400-7-722 describes detailed requirements for the design and maintenance of charging points.
In practice, there are two alternative solutions for normal charging:
– Charging station (Mode 3) – either with Type 2 connector or fixed cable with plug
– Ordinary connector (Mode 2)
DSB’s clear recommendation is to install a charging station (Mode 3) because it provides good safety, charges quickly and has great flexibility. A Mode 3 charging station will have a long service life and is normally prepared for charge management. This can reduce costs when “queue pricing” of electricity is introduced in one or two years. The visible difference between the options is that a Mode 3 has the charging box screwed to the wall, while a Mode 2 charger is a cable with an attached charging box.
The charging cable is plugged into a standard earthed socket (known in the trade as a Schuko socket). A box that controls the charging current and monitors safety is attached to the charging cable. If charging from a standard earthed socket is facilitated, this must be supplied from a separate circuit (except for detached private garages) with a maximum 10A fuse. The circuit must be protected by a separate B-type RCD (not disturbed by noise from the vehicle’s charging system) and a surge protector. Remember to hang the charging box in a basket or hook – the connector will be destroyed by the weight of the charging box and cable, resulting in overheating.
Application for charger
Føre AS requires an application if a charging point with a capacity of more than 20 A is installed. Notification of this is sent in Elsmart via an authorized installer.
This requirement has been introduced to ensure that the grid company complies with the Regulations on quality of supply in the power system (FOL).
