Mobility - EV Charging Stations

1. Standard connection diagram

The Climkit Mobility system consists of the installation of smart charging stations that communicate with the Climkit Gateway via the OCPP protocol.

Through this communication and the installation of continuously monitored meters, the Climkit Gateway can regulate the available power allocated to the charging stations and also manage user access identified via RFID badges.

Connection in an RCP

In a Climkit RCP (see Community - Electrical Metering - RCP), a meter is installed on each distribution area branch (flat cable). This meter is never installed behind that of the common areas.

Connection of the I/O Module

The I/O Module is used to detect a command from the DSO meter for load shedding of the charging stations.

2. Connection diagram - A parking lot and multiple introductions

When there are multiple connections available for the same parking lot, each flat cable branch (63A) is taken from each of the connections.

Only one gateway and 4G router are needed. The control meters for power regulation are connected to the gateway via an RS485 or IP-ethernet bus using RS485-Ethernet converters.

Option A: Charging Stations Connected to the DSO Meter of Common Areas

In the diagram below, there are 2 flat cable branches taken behind the DSO meter of the common areas of each building.

In this case, a Climkit meter for power regulation must be installed on the branch for the common areas!

Option B: Charging Stations Connected to a Dedicated DSO Meter

In the diagram below, there are 2 flat cable branches taken behind a dedicated DSO meter for the charging stations for each building. Therefore, it is not necessary to install a Climkit meter on the branch for the common areas.

3. Flat Cable in Collective Parking Lots

For small installations, a few charging stations can be individually connected to the building's electrical panel and connected via Ethernet or Wi-Fi.

However, for larger parking lots, it is recommended to install a flat cable to bring electricity to each parking space, thus facilitating the installation of a charging station as residents wish to equip themselves.

This is recommended by level C1 of the SIA 2060.

We recommend the installation of a 5x16mm2 flat cable from Woertz or Wieland along the parking spaces to be equipped.

The cable is fixed directly with clips to the wall or ceiling.

Thanks to the IP65 junction boxes with insulation piercing, the charging stations can then be easily connected without cutting or stripping the cable.

The flat cable is powered via a 3P+N LS circuit breaker of max 63A from the electrical panel (provided by the electrical installer).

Although the number of charging stations per area is unlimited, it is recommended not to connect more than 30.

Each station is then equipped with an A-type RCD of 16 (11 kW) to 32A (22 kW) and connects to the management system via Wi-Fi.
