Chroma Developed an Exclusive Motor Controller for Smart EV in Taiwan

On August, 29, 2017 the general manager of Chroma’s Integrated System Solution BU, I-Shih Tseng, was invited to present the research and development results on HAITEC (Hua-chuang Automobile Information Technical Center Co., Ltd.) vehicle platform in “Taiwan Automotive Technology Innovation and Development Summit.” I-Shih expressed that reducing carbon emissions is a common goal for countries around the world, and Taiwan cannot remain on the sidelines. Today’s focal point, LUXGEN S3 EV+ is a 100% self-developed smart electric vehicle as a pioneer in reducing carbon emissions in Taiwan.

 

The global sales of electric vehicles were up to 774,000 units in 2016, up 42% from 2015. Lately, many countries have started to put forward EV related policies. For instance, Norway took the lead to set up the goal of fully electric cars on the market in 2025 while Britain and France announced that they will ban the sale of new petrol and diesel cars from 2040. In response to these policies, the international automakers have set up strategies to deal with these changes; for example, Volvo announced in July that all its car models launched after 2019 would be electric or hybrids.

HAITEC has been actively involved in the development of electric vehicles in recent years. Through the collaboration of industry, academia, and government, an ecosystem team encompassing motor, controller, battery, on-board charger and other key components manufacturers was formed to successfully create a Taiwan developed a smart electric vehicle. I-Shih also pointed out that the city S3 EV+ was developed suitable for Taiwan terrain and traffic condition as a smart energy passenger car with a speed dial b-Paddle. It is equipped with regenerative braking function to save energy when driving on the road, with power consumption of only 130Wh per kilometer. It can also be used as a mobile energy storage system (ESS) to integrate with micro-grid for household emergency use.

In electric vehicle powertrain system, Chroma is dedicated to developing motor control unit (power inverter). We aggressively cooperate with HAITEC to develop the controller exclusive to S3 EV + with power up to 150kW, efficiency up to 97%, and power density up to 15kW per liter. For the most important indicators of a vehicle – reliability and safety, Chroma’s motor control unit has passed the automotive level verification tests to be in compliance with international level quality.

At last, I-Shih expressed the appreciations to the consortium members, including Industrial Technology Research Institute, Automotive Research and Testing Center, National Taiwan University, Taiwan University of Science and Technology, and Taipei University of Science and Technology for their great efforts in completing the electrification of powertrain that was successfully been integrated in Taiwan’s first self-developed S3 EV+ smart electric vehicle, and making the automobile industry moving towards a whole new milestone.
