Heliox, a subsidiary of Siemens, has introduced the 44 kW V2G DC charger in the United States — an all-in-one fast-charging system featuring full vehicle-to-grid (V2G) functionality. Designed for electric truck and bus fleets, the charger enables operators to optimise energy use, reduce costs, and contribute to grid stability through bidirectional energy transfer.
Delivering up to 44 kW of power, the Heliox V2G system supports both networked and standalone operation and complies with ISO 15118-20 and SAE J2847 standards to ensure interoperability with a broad range of present and future electric vehicles.

Its adjustable AC input range of 15 to 56 amps allows deployment in areas with limited grid capacity, while the compact, all-in-one design supports wall-mounted or pedestal configurations for both indoor and outdoor installations.
The charger incorporates time-of-use scheduling and energy transfer programming, allowing fleet operators to optimise charging costs and, when needed, sell energy back to the grid. It also enables vehicles to act as backup power sources during outages, further improving operational resilience.

Manufactured and tested in the United States, the Heliox 44 kW V2G charger is fully compliant with the Buy America Act, qualifying it for federal and state-funded electrification initiatives. Heliox also offers 30 kW and 60 kW DC chargers for fleet applications, though these variants do not include vehicle-to-grid capabilities.
