OSM inks MoU with Korea’s Jae Sung Tech to manufacture e-powertrains in India

by Autocar Pro News Desk , 06 Jan 2022


Based on internal testing by the partners, the new powertrain is 30 percent more efficient and 20 percent lighter than existing powertrains being used in the electric three-wheelers at the moment.

Omega Seiki Mobility (OSM) and South Korean electric vehicle powertrain manufacturer Jae Sung Tech Co have inked a strategic partnership to form a JV – OSM Jae Sung Tech Co, which will manufacture electric powertrains in India.

The all-electric Ra314 powertrain will be manufactured by OSM at its facility in Faridabad and in Pune at its group company, Omega Bright Steel and Components’ facility, which will be the first product and will be used in the OSM Rage+ in Q1 FY 2023. Jae Sung will be bringing in its years of experience with the technical knowhow while OSM will be bringing in its manufacturing prowess to localise the powertrain. OSM will also test and calibrate the Ra314 for typical Indian driving conditions.

OSM says the Ra314 offers a silent drive, simple architecture, and superior durability. Being IP-67 rated it can perform even after being submerged in water for 30 minutes. Based on internal testing by the partners, the new powertrain is 30 percent more efficient and 20 percent lighter than existing powertrains being used in the electric three-wheelers at the moment. The Ra314 uses an integrated motor, gearbox design, which leads to significant weight saving as well as improved vehicle efficiency.

Using an integrated architecture helps reduce the number of moving parts leading to lesser amount of wear and tear. This enables longer service intervals and reduce overall service costs for the end customer. Furthermore, the modular architecture will also allow OSM to develop the Ra314 for four-wheeler SCVs.

Uday Narang, founder and chairman, Omega Seiki Mobility said, “OSM has always believed in constant innovation and is always working to make the product portfolio a step ahead of the competition. With this JV, I am sure the Rage+ will be an even better value proposition. Not only will the new power unit herald a new era of backward integration making our products more efficient. We will also utilise Ra314’s integrated and modular architecture to build customised power solutions for other EV makers in India to use, thus helping in faster adoption of electric vehicles in India.”

Lee Hyunjin, CEO, Jae Sung Tech Co said, “We are delighted to partner with Omega Seiki Mobility, which is a pioneer in electric vehicle manufacturing. Our overall powertrain architecture and integration was developed with flexibility in mind to allow us to quickly adapt to the ongoing changes and developments in the industry. As a technology company, Jae Sung always believes in developing innovative solutions which are environment friendly as well as cost effective. I am positive that our advanced technologies, strong engineering background when combined with OSM’s manufacturing expertise in India, will help us to strengthen our partnership and succeed together in this rapidly growing segment.”

The partners claim that the Ra314 has been tested extensively and is being engineered to work in extreme temperature range of +50deg C to -20deg C.

Dr. Deb Mukherji, MD, Omega Seiki Mobility said, “We will be developing Ra314 completely in India with Jae Sung technology support. It’s a next gen powertrain with IoT which will help our customers keep a track of their vehicle’s performance via an app, in a cell phone. We will also be utilising the power unit in upcoming OSM products in the near future which will include three-wheelers as well as four-wheelers.”
