Prestolite E-Propulsion Systems (PEPS), a 50/50 joint-venture between Prestolite Electric Beijing Limited and TM4 Inc., has received an order for more than 200 SUMO HD electric powertrains from Foton, one of China’s largest bus manufacturers. These systems will equip 12- and 18-meter buses.
PEPS has been working closely with Foton over the last 18 months in a trial period under which the SUMO HD systems outperformed the competition. The new order is in addition to a recent order for more than 100 SUMO MD and HD powertrains for BLK, announced last July.
The TM4 SUMO systems are optimized for medium-and heavy-duty electric and hybrid vehicles such as 6-18 meter buses, delivery trucks, shuttles, tow tractors and more. The direct-drive system yields more than 10% efficiency gains throughout the driving cycle, representing an equivalent gain in battery usage, the company said. Some of TM4 SUMO systems are offered with a double-ended shaft option, allowing for easy integration in many hybrid-electric powertrain architectures.
TM4, a wholly owned subsidiary of Hydro-Québec established in 1998, pioneered the electric propulsion system technology developed by Hydro-Quebec’s research center (IREQ). Today, it provides customers in more than a dozen countries with patented technology and expertise in electric motors, generators and inverters for the transport and energy markets.
Leveraging TM4’s licensed technologies and PEBL’s (Prestolite Electric Beijing Limited) network and reputation in ASEAN markets, Prestolite E-Propulsion System is providing high-end solutions for clean transport and sustainable mobility by developing, manufacturing, selling and supporting electric traction systems for trucks and buses, as well as commercial, off-road and marine vehicles.
The joint venture is supplying clients in the People’s Republic of China, Taiwan, Hong Kong, Macao, Indonesia, Philippines, Thailand, Singapore and the rest of ASEAN countries.
