Chargepoint infrastructure requires good internet connection to enable communication with the back-office system. Bays with average signal benefit from additional network cabling. This is best installed with the chargepoint electrical cabling to reduce installation costs.
The Barbican Estate had to consider internet signal when choosing the location of their chargepoints, particularly as they would be located in an underground car park.
The installer should check the strength of the network signal with appropriate equipment. The resident management company should accompany the installer to check the network signal, to understand the signal strength in each bay, as well as how a good or poor signal is identified. The installer can suggest chargepoint locations, though the management team must ultimately make the final decision to install in bays receiving a good signal or upgrade the network connection in poor signal areas.
At the Barbican Estate, chargepoint locations were decided based on a balance between good internet signal at the bay and being close to the distribution board. The distribution board splits the incoming power supply to multiple circuits. The nearer the bays are to the distribution board, the lower the installation cost, as less digging through concrete is required. In addition to the capital costs, the Barbican Estate will have to pay regular internet costs for the chargepoint infrastructure.
