Computerised scheduling for electric vehicle charging

The team has devised a system where electric vehicle owners use computerised agents to bid for the power to charge their vehicles and also organise time slots when a vehicle is available for charging.

Increased uptake of electric vehicles is predicted to put considerable strain on local distribution networks, especially at peak times.

To address this, some distribution companies that are already experiencing significant EV use (such as the Pacific Gas and Electric Company in California) have introduced time-of-use pricing plans for EV charging that attempt to dissuade owners from charging their vehicles at peak times, when the local electricity distribution network is already close to capacity.

Researchers have also begun to investigate the automatic scheduling of EV charging — where individual vehicle owners indicate the times at which the car will be available for charging, allowing automatic scheduling while satisfying the constraints of the distribution network.

However, because these approaches separate the scheduling of the charging from the price paid for the electricity (typically assuming a fixed per-unit price plan), they are unable to preclude the incentive to misreport (for example, an owner may indicate an earlier departure time or further travel distances in order to receive preferential charging).
