Smart EV Charging Station


This Smart EV Charging Station connects multiple parking spaces to monitor and analyse power usage of Electric Vehicle (EV) chargers in real-time, optimising the use of limited power. It provides rated power (100%) when there are only a few EVs. When more EVs are connected, the system can reduce power output of some chargers (e.g. 50%), so as to allocate additional power to the just-arrived vehicles.

Problem addressed

The electic power distributed to car park in building is minimal. The electric load capacity for medium / quick charge is generally insufficient at EV charging stations. Retrofitting extra power transformer requires extra space and costs.

  • More medium chargers can be installed in existing old buildings which have limited spare power capacity.
  • Fully utilise the building’s power capacity for EV charging station; especially when the power consumption is low during night time.
  • Smart power management and Internet of Things (IoT) elements of the System can leverage Smart Grid to enable Smart City (e.g. reducing peak demand, two-way flow of electricity and data).
Key impact
  • Real-time monitor the power usage of EV chargers.
  • Effectively allocate the carpark electricity capacity for EV charging stations.
  • Enable the installation of more EV chargers in old buildings or buildings with limited spare electricity capacity.
  • Old carpark or carparks with limited spare electricity capacity for EV charging stations
  • Carpark requiring large-scale installation of EV chargers
