Vehicle-to-Grid

Scenario 2: Integration of V2G Technology for Private EV Chargers

Solar-Rich and Grid-Strained: Navigating Energy Choices in a Wealthy Suburb

Amelia lives in a wealthy suburban neighbourhood where many residents have installed solar panels on their roofs and their own electric vehicles (EVs). These homes are now equipped with Vehicle-to-Grid (V2G) technology, which allows EVs not only to charge from the grid but also to send electricity back into it when needed.

One evening, Amelia plugs her EV into the charger in her driveway. Her charger is set to work with an Automated Decision-Making (ADM) system, which manages when her car charges or discharges energy based on how much electricity the grid needs and the battery's status. The system calculates the best time for her car to charge, and a message pops up: "Charging will start at 23:00 at night. when electricity is cheaper. Your car will be fully charged by 07:00 in the morning".

Later that night, at 20:00, Amelia receives a notification on her phone: "Due to high electricity demand in your neighbourhood, your car could help support the grid by discharging some power. You’ll receive a €5,- credit. Your energy could help maintain electricity for a nearby family with a newborn who needs constant heating due to a medical condition. Would you like to proceed?"

Amelia, knowing that she does not need her car fully charged in the morning, agrees to discharge some energy. She feels good about helping her neighbours and receiving a small reward while still ensuring her car will be ready by the next day.

At the same time, her neighbour Liam receives the same message. However, Liam has a long trip planned for early next morning and worries that discharging too much energy will leave him with insufficient charge. He decides to decline the offer and opts to keep his battery full, knowing that the Automated Decision-Making system allows him to prioritise his own needs.
