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 stations and also manage user access, which is identified via RFID badges.

Connection of the I/O Module

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

2. Connection Diagram - A Parking Lot and Multiple Inputs

When multiple inputs to the grid are available for the same parking lot, each flat cable branch (63A) is taken from each input.

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

Option A: Supply of Stations from the Common GRD Meter

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

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

Option B: Supply of Stations from a Dedicated GRD Meter

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

3. Flat Cable in Collective Parking Lots

For small installations, a few stations can be connected individually 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 supply electricity to each parking space, thereby facilitating the installation of a charging station as residents wish to equip themselves.

This is what is recommended by level C1 of the SIA 2060.

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

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

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

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

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

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