CHINA BREAKTHROUGH FOR NEW EV MOTOR CONTROL TECHNOLOGY



by Jon Knox

Electric vehicle controller specialist Sevcon has won a contract to supply pioneering drivetrain control technology for a new range of utility and all terrain vehicles being manufactured in China.

Sevcon is to supply its specialist Gen 4 microprocessor controllers for an innovative powertrain platform developed by the Zhejiang Xinyang Industry Co. Ltd., an established manufacturer of UTVs, ATVs, Jeeps, Go Karts and amphibious vehicles.

The new electric range of UTVs is being developed for sale in Europe, USA and Southeast Asia and is powered by a 48V, 5kW motor, which will be controlled by a Sevcon Gen4 size 4 motor controller.

The new vehicle, which will have a top speed of 45kph and a range of up to 80km, attracted considerable interest at its recent launch at the EICMA show in Milan.

The Gen4 motor controller ensures the smooth and effective delivery of energy from the battery to the motor controlling speed and acceleration. The high efficiency of the Gen4 maximises the range and performance of the vehicle whilst offering long life even in demanding ATV applications.

In winning this contract to supply the Gen4 technology to Zhejian Xinyang, Sevcon worked closely with its local representative, Shanghai FangAn Engineering Technology Co. Ltd., to provide vehicle performance, power engineering and technical recommendations for the new drivetrain platform.

The Sevcon Gen4 series represents the very latest in compact AC motor control technology, delivering a high power capacity relative to unit size. Across the complete Gen4 range, motor controllers are available for operating voltages up to 800V DC and providing output power up to 280kW.

Sevcon Limited is a wholly owned subsidiary of Sevcon Inc and is registered on the NASDAQ exchange in the USA. The company is a world leader in the design and manufacture of microprocessor controls for zero emission electric vehicles and hybrids. With offices around the world and 70 staff in the UK, global sales are more than $30M. Customers include manufacturers of on-road, off-road and industrial vehicles including cars, motorcycles, buses, fork lift trucks and aerial lifts.
