EcoCharge is an innovative framework whose objective is to allow drivers to recharge their Electric Vehicles (EVs) from the most environmentally friendly chargers using an intelligent hoarding approach. It internally deploys a Continuous k-Nearest Neighbor query, where the distance function is computed using Estimated Components (ECs) (i.e., a query we term CkNN-EC). An EC defines a function that can have a fuzzy value based on some estimates. Examples of ECs are: (i) the derouting cost, which is the time to reach the charger depending on estimated traffic; (ii) the (available clean) power at the charger, which depends on the estimated weather; and (iii) the charger availability, which depends on the estimated busy timetables that show when the charger is crowded. EcoCharge framework combines these multiple non-conflicting objectives into an optimization task providing user-defined ranking means through an intuitive spatial application.
EcoCharge has been developed by researchers and students at the Data Management Systems Laboratory (DMSL), Department of Computer Science at the University of Cyprus.

EcoCharge is a novel framework designed to optimize electric vehicle (EV) charging by prioritizing environmentally friendly chargers that maximize renewable energy use and minimize CO2 emissions. It employs a Continuous k-Nearest Neighbor (CkNN) search with Estimated Components to dynamically rank chargers based on factors like travel time, renewable energy availability, and charger occupancy. The EcoCharge algorithm integrates these parameters into an optimization task, presented through a user-friendly spatial application.
