Charging station

Load management continuously measures the load at the grid connection and distributes the available power across the connected charging points so that the connection is not overloaded. In The Mobility House’s ChargePilot, a RevPi Connect handles this directly on site, to the second and even if the internet connection fails. Local consumers such as buildings and generators such as photovoltaic systems are factored in, and the data is also sent to a cloud backend.

Via the Open Charge Point Protocol (OCPP), the charging station exchanges authentication and billing data with the charge point operator. At Compleo, users identify themselves via app or RFID charging card, and backend systems in the cloud check the authorisation and start the charging session. Billing data is passed on to the e-mobility provider. Through roaming platforms, its customers can charge at every charging point, even with different tariffs.

Businesses integrate charging stations into their energy management together with buildings, generation and storage instead of running them in isolation. At its Sondershausen logistics centre, WAGO records charging station data together with heat pumps, ventilation and lighting and uses it for load management that avoids peak periods. PRAMAC Storage Systems buffers the electricity for its company fleet’s charging stations in a battery storage system that also stores solar power.

Charging stations send status, usage and billing data to a cloud backend via the cellular network. There, operators see utilisation, reset stations remotely, fix minor technical problems and query the maintenance status, as Compleo describes. Technicians therefore know in advance which spare parts they need. In the solution built on Cumulocity, a central dashboard shows complete installations as well as each individual device.
