The future for EVs: Reducing network costs and disruption

Electric vehicles are becoming more commonplace on our streets, and already, small pockets, or `clusters´ of EV owners are forming. If clusters of EVs on one feeder all charge during the normal peak electricity demand, this could overload feeders resulting in network operators having to implement costly reinforcement. However, during off peak times there is existing capacity on local feeders. A system to allow direct control of charging of EVs has been developed called Esprit. To test the system, clusters of EVs need to be `created´. This is being carried out via the Ofgem Low Carbon Networks Fund project `My Electric Avenue´ (I2EV). In return for a reduced monthly charge on an 18 month lease, participants will allow their EV charger to be controlled, data to be collected and will provide feedback on their experience. The success of this trial relies on close working between Distribution Network Operators, technology developers, communities, EV manufacturers, academics and car leasing companies.
