EV Charging System with Intelligent Load Management Control

The lack of charging facilities is a common complaint among EV drivers. In fact, the number of chargers allowed for installation in a carpark depends on the size of its electricity resource. Our charging system provides intelligent load management using our advanced control algorithms. Under the condition that the incoming supply remains unchanged, the system can intelligently distribute the supply current to all connected EV chargers according to the actual electricity demand of each EV. It can optimize the utilization of electricity resource by allowing installation of more additional chargers, enabling full-power charging and reducing at least 50% of energy provision. It is expected the system will be adopted in 8 carparks in Hong Kong, involving over 100 chargers, by the end of 2019.
