Most EV charging companies are at the early stage of integrating devices with broader on-site power management needs and adding bi-directional charging has been mostly limited to research.
At Wallbox HQ, cars are charged with grid power during the night and discharge electricity to the building during daytime. “We use the power from our batteries in the early morning, when electricity tariffs in Spain are high, and then recharge them with solar power during the day to reduce our electricity consumption from the grid in the late afternoon,” says Utges.
“Our fleet of cars is intended for internal mobility, from the HQ to the factory (5 km), and some for commercial visits, but not to go on a long trip, to Madrid, for example,” he explains. “This can be booked and we can prepare a car for a long a trip as well but it’s probably easier to go to a fast charger here on the premises and fill your car in half an hour, than to use Quasar, that gives you only 7.4 kW.”
