Enova Systems, Inc. engages in the development, design, and production of drive systems and related components for electric, hybrid-electric, fuel cell, and microturbine-powered vehicles. It also develops, designs, and produces power management and power conversion components for stationary distributed power generation systems. Its products include electric and hybrid-electric drive systems, electric drive motor, electric motor controllers, hybrid drive systems, battery care unit, hybrid control unit, safety disconnect unit, fuel cell power conditioning unit, ice generator unit, and fuel cell management. The power management systems control and monitor electric power in an automotive or commercial application, such as an automobile or a stand-alone power generator. The drive systems comprises an electric motor, an electronic control unit, and a gear unit that power an electric vehicle. Hybrid systems contain an internal combustion engine and an electric motor, and are used to eliminate external recharging of the battery system. A fuel cell combines hydrogen and oxygen in a chemical process to produce electricity.
