Description and history
Enova Systems, Inc. (Enova), incorporated on July 30, 1976, is engaged in the development, design and production of power train systems and related components for electric and hybrid electric buses and medium and heavy duty commercial vehicles and stationary power generation systems. The Company develops, designs and produces drive systems and related components for electric, hybrid electric and fuel cell powered vehicles in both the new and retrofit markets. It also develops, designs and produces power management and power conversion components for stationary distributed power generation systems. Additionally, it performs internal research and development (R&D) and funded third party R&D to augment its product development and support its customers. During the year ended December 31, 2009, Enova developed and produced electric and hybrid electric drive systems and components for First Auto Works of China (FAW), Navistar Corporation (Navistar), Tanfield Engineering Plc (Tanfield) and the United States Military, as well as several other domestic and international vehicle and bus manufacturers.

The hybrid and electric power system consists of an enhanced electric motor and the electronic controls that regulate the flow of electricity to and from the batteries at various voltages and power to propel the vehicle. The Company’s hybrid drive systems, in conjunction with, internal combustion engines, microturbines, fuel cells, flywheels, and generator sets provide hybrid and electric propulsion systems. There are two types of hybrid systems: series and parallel.

Enova’s main component is an inverter, which converts direct current (DC) electricity to alternating current (AC) electricity. It also offers optional controllers for the air conditioning, power steering and heat pumps, 12VDC/24VDC DC-to-DC converter for vehicle auxiliary loads, such as cell phones, radio, lights, and a 6.6 kilowatt AC-to-DC on-board conductive charger which allows for direct 110 VAC or 220 VAC battery charging. Using its Windows based software package, vehicle interfaces and control parameters can be programmed in-vehicle. Real-time vehicle performance parameters can be monitored and collected.

The Enova drive system family includes a 120/60 kilowatt peak series hybrid system, a 240/120 kilowatt peak series hybrid system, a 90 kilowatt peak mild, pre-transmission parallel hybrid system, a 90 kilowatt peak post-transmission parallel hybrid systems and its 80 kilowatt peak pre-transmission parallel hybrid system. The Enova hybrid-electric drive systems are based on the component building blocks of the electric drive family, including the motor, controller and optional components. Its hybrid systems are designed to work with a variety of hybrid power generation technologies. In its 120/60 kilowatt hybrid system, an internal combustion engine connected to a motor and motor controller performs the power generation. Other power options include liquid fueled turbines, such as the Capstone system, fuel cells, such as the Hydrogenics or Ballard system, or many others.

Enova’s drive system accessories range from battery management systems to hybrid controllers, to rapid charging systems. These critical components are designed to complement the drive system family by providing the elements necessary to create a complete technical solution for alternative energy drive systems. Enova’s Battery Care Unit (BCU) monitors, manages, protects, and reports on the condition of the vehicles battery pack. It controls and manages battery performance, temperature, voltage and current to avoid harm to the batteries, to the entire system, and to the driver, operator and passengers. It also allows for monitoring for service to the battery and drive system.

Enova has reconfigured its Battery Care Unit to perform the critical role of hybrid controller. The Hybrid Control Unit (HCU) monitors the condition of the battery pack through communications with the BCU, monitors the driver commands through communications with the motor controller, and the state of the hybrid generator. Based upon the data received, the HCU provides continuous updates to the hybrid generator with instructions on mode of operation and power level. The Safety Disconnect Unit (SDU) is under the control of the BCU, and allows vehicle systems to connect and disconnect from the battery pack, when necessary, to prevent damage or harm. It also protects the battery pack during charging, protects it from surges, and constantly verifies that the battery pack is isolated from the vehicle chassis.

The High Voltage Disconnect Unit (HVDU) is a reduced feature version of the Safety Disconnect Unit. The pre-charge board has been eliminated in order to provide a lower cost method of safely switching high voltage systems on the vehicle that do not require the soft start feature. It provides complete mating connector kits to help the vehicle OEM with their production process. Enova’s distributed generation products are virtually identical in system configuration to that of a series hybrid vehicle, including a controller and battery management. Enova’s 20 kilowatt bi-directional Fuel Cell Power Conditioning System, originally designed to meet the demands of an automotive Fuel Cell propulsion system, is being applied to the stationary market for distributed generation applications.

Enova has reconfigured its Battery Management Unit to perform the functions required to monitor, manage, and report on the status of a Fuel Cell Stack. The FCU monitors the fuel cell voltage and 28 additional individual voltages with a range of 0 to 18vDC. Optional expansion modules allow 28 additional inputs per module, with up to 16 modules permitted. The FCU has eight user-programmable outputs and four user-programmable inputs to allow full integration into the distributed generation system. These can be used to customize input and output parameters, and to provide for other custom monitoring and battery pack control. The device is approximately 7.1 inches by 4.3 inches by 1.6 inches.

The Company competes with Allison, Siemens, BAE, Eaton, ISE Corporation, Azure Dynamics and UQM Technologies.
