As the world’s biggest cities work to understand how their infrastructure can help them build clean and sustainable economies, a group of companies is helping in the effort with a study of what they’re calling vehicle-to-everything (V2X) charging.
Hitachi Europe Ltd., Mitsubishi Motors and French utility ENGIE launched a demonstration project for Hitachi’s V2X charger for an office building in North Holland, Netherlands. A next-gen approach to vehicle-to-grid charging, V2X can recharge an electric vehicle (EV) and discharge the energy back into a building or the grid, providing different flexibilities, such as kW, ΔkW, kWh and VAR. The companies said it is also possible to connect solar panels and external storage directly to the recharger.

“This demonstration will help provide a new energy solution for energy efficient, low-carbon smart buildings,” Vincent Cobee, corporate vice president at Mitsubishi Motors, said in a statement. “We are aiming to show that EVs and [plug-in hybrid] EVs can be a vital component of urban energy in the future.”
The V2X charger connects to a building’s energy supply and stores excess power in car batteries when the building generates more solar power than it needs. The companies said the energy can also be discharged to the grid, allowing the car battery to act as an energy storage source and an emergency power supply.
The project will include the study of how EVs, renewable energy and building energy management systems can work together to enable buildings to become energy-neutral.
