Azure Dynamics Corporation specializes in the development and provision of electric and hybrid electric propulsion systems, along with vehicle control technologies, for commercial vehicles ranging from light to heavy-duty, primarily in North America. Their hybrid electric vehicle (HEV) systems integrate an electric motor, an energy storage unit, and an additional power source, such as an internal combustion engine/generator. In contrast, their purely electric vehicle (EV) systems comprise an electric motor paired with an energy storage system.
