Hyundai has partnered with Dutch dynamic provider Wi-Drive Solar to implement the world’s first two-way vehicle-to-grid (V2G) power system. The project takes place in Utrecht (a city in the Netherlands), where a fleet of 150 Ioniq 5 EVs will be deployed to supply electricity to about 2,530 homes!
The Ioniq 5 has already earned acclaim for its car-to-load (V2L; rear seat socket) capabilities, allowing it to provide up to 3.6 kilowatts of alternative current for electricity / charge, such as electric bicycles, scooters, and camping equipment. Even another EV with a dead battery. Note that the factory Ioniq 5s does not currently support V2G (these have been modified), but plans to make this standard in the future.
The move makes Utretch the first city in the world to have such large-scale V2G technology installed and will become the first bi-directional neighbor of Cartesius’s newly-developed neighborhood.
Two-way charging – or V2G – is a technology that allows vehicles to send electricity back to the grid, as opposed to one-way chargers that provide only one-way power flow from the grid to charge the car.
This technology allows EVs to power the household when there is a need for extra energy, such as when you are hosting a movie night or dinner party. Owners will be able to recharge their BEVs at low cost during off-peak hours. Win-win.
This increases energy consumption throughout the day and stabilizes energy production, making it an ideal way to manage energy in the future. Think of cars as wheeled power banks – when you’re not driving them, why not power them on your air conditioning, kettle, lights and TV?
The V2G can only work with a two-way charger, which has a built-in inverter to convert the DC current of the vehicle to AC (EVs and PHEV also have inverters that convert to AC). The municipality of Utrecht has installed 1,000 units of two-way charger across the city in the last three years.
Michael Cole, President and CEO of Hyundai Motor Europe, said: “At Hyundai, we believe that dual-charging batteries with V2G technology can turn electric vehicles into flexible assets. Ioniq 5 and V2G technology not only provide an alternative solution for customers looking to move away from traditional combustion engines, but also help increase the efficiency of renewable energy generation within the grid. “
Robin Berg, Director of We Drive Solar, says: “With the unique vehicle-to-grid technology, we can use drive solar vehicles for sustainable energy storage on a large scale, moving from 25 to 150 Ioniq 5 units this year. Together with Hyundai, we will make Utrecht the world’s first city and region with a two-way power ecosystem. “
