Tech/Ops Sevcon, Inc. (NASDAQ symbol TO) today announced that a pioneering project to develop a new generation of hybrid drive systems for electric vehicles will incorporate state-of-the-art motor control-technology engineered by Sevcon.

Sevcon is part of a consortium, which includes UK-based Ashwoods Automotive, working on a £1.8m ($2.8m) project to develop the next generation of hybrid drive trains which are scalable from 25kW up to 150 kW. The groundbreaking initiative also involves Citroen and LifeBATT and is part-funded by the UK Technology Strategy Board. The hybrid drive train, which will be suitable for a range of commercial vehicles, will incorporate Sevcon’s latest Gen4 AC motor controller. The motor controller has a stop/start engine system which reduces fuel consumption and emissions and can be fitted in a short time.

The proprietary system consists of Sevcon’s Gen4 AC motor controller and an Intelligent Power Pack Module (IPPM). The Gen4 range, which is designed to control either AC asynchronous or PMAC synchronous motors, incorporates the latest in electronic motor control technology and enclosure assembly to provide the smallest controllers in the industry relative to power delivery. Gen4 controllers can be integrated into very tight engine compartments without sacrificing performance and are designed to handle a wide range of electric vehicle requirements.

Gen4 controllers operate with nominal battery voltages of 24-36 VDC, 36-48 VDC and 72-96 VDC and peak currents of 275A (for the 24V and 48V versions) and 180A. The fully sealed IP66 rated enclosures of the Gen4 range are designed to handle a wide range of electric vehicle requirements. Gen4 motor controllers are fully CANopen compliant and the CANbus enables simple and flexible vehicle integration of motor controllers and devices through a fully integrated set of inputs and outputs. Implementation of advanced flux vector control improves traction control efficiency and motor responsiveness which helps channel drive power and energy from the battery smoothly and efficiently. The motor controller can provide functions such as throttle, direction and other drive interlocks. The Gen4 series controllers are also equipped with a self-characterization capability to automatically define and optimize AC asynchronous motor operating parameters which allows customers to select motor suppliers of their choice for any application without worrying about compatibility between controller and motor.

Tech/Ops Sevcon, Inc. is a world leader in the design, manufacture and marketing of microprocessor based controls for zero emission electric vehicles. The controls are used to vary the speed and movement of vehicles, to integrate specialized functions, and to optimize the energy consumption of the vehicles’ power source. Sevcon supplies customers throughout the world from its operations in the USA, the United Kingdom, France, and the Far East, and through an international dealer network. The Company's customers are manufacturers of on and off road vehicles including cars, trucks, buses, motorcycles, fork lift trucks, aerial lifts, mining vehicles, airport tractors, sweepers, and other electrically powered vehicles.
