Swedish/Swiss energy optimization specialist Energy Bank is now installing 200 bidirectional chargers in Sweden, connecting multiple grid operators with EV drivers.
Energy Bank tested its V2G technology at the Stenberg Housing Association in Hudiksvall, Sweden over a period of 15 months, and is now scaling up to a larger pilot program that it calls “the next step toward a commercial offering.”
Working with Swedish electric utility Vattenfall, Volkswagen, and installation partner Transtema Charge, Energy Bank will enable some 200 EV owners (both private households and businesses) to provide grid services for compensation. The V2X pilot is based on DC charging using the CCS standard.
Volkswagen’s MEB and MEB Plus platforms support bidirectional DC charging. Energy Bank acts as the technical aggregator, pooling flexibility from all connected vehicles and delivering it via its API integration to Vattenfall.
“Other V2G aggregators package flexibility and decide how it is used. Energy Bank does the opposite,” says the company. “We aggregate capacity from connected EVs and hand control to the grid owner or electricity supplier.”
“This project shows that EVs can become an active and valuable part of the energy system,” said Klas Boman, co-founder of Energy Bank. “This is an important step toward a new market where mobility and energy meet, and where the EV owner helps drive the energy transition.”
“Our collaboration explores how aggregated EV batteries can contribute flexibility and support system balance and stability,” said Magnus Berg, Manager Customer Products and Solutions, Vattenfall. “If the battery can support the power system and generate revenue, it is a way to improve the economics of owning an EV and contribute to further electrification.”
“Volkswagen MEB platform vehicles are ready for bidirectional charging today,” said Derek von Rönn, Business Owner, Charging, Volkswagen. “With fast response times and the ability to deliver multiple grid services, our EVs are not just means of transport—they are mobile energy assets.”
