ePropelled releases groundbreaking electric vehicle Motor System at CENEX-LCV
ePropelled, a Massachusetts-based technology firm that develops cutting-edge electric propulsion systems, today announced the launching of a revolutionary new electric vehicle (EV) propulsion system that will be demonstrated at the Cenex-LCV in Millbrook, United Kingdom.
This innovative technology significantly improves power efficiency, allowing manufacturers to shrink the size and cost of their battery packs. Battery packs can contribute for up to 30% of car costs, rendering smaller EVs uneconomical. Reduced costs will increase the profitability of EVs while also boosting customer uptake.
Dynamic Torque SwitchingTM (eDTS) by ePropelled is a software-controlled reconfigurable propulsion motor that serves as the cornerstone for a complete electric vehicle propulsion system. eDTS enables the electric motor to provide a large amount of torque at low speeds without taking a large amount of current from the batteries. Additionally, it achieves high speeds at low torque levels without the use of field weakening, enhancing overall efficiency. eDTS is a scalable design that may be utilised in a variety of electric vehicles, from small electric vehicles such as scooters and three-wheelers used for last-mile delivery to large electric vehicles such as cars and trucks.
This patented technology is a drive system concept that enables a single electric machine to dynamically switch between different modes, hence providing a far broader range of high-efficiency applications with low power consumption. The control system is designed to provide seamless transitions between modes, resulting in real-time delivery of the optimal torque, speed, and efficiency characteristics.
The technology company will unveil and demonstrate its cutting-edge electric motor technology at the Cenex-LCV 2021 show in Millbrook on September 22-23, at the ARMD stand, #SP-20, and the Wales stand, #C3-117. ePropelled collaborated with Tata Motors on the installation of the eDTS system in a Tata Tiago, which will also be on exhibit at the Cenex-LCV conference. This configuration of the new propulsion system generates up to 180 kW of peak power and 60 kW of continuous power (for 10 seconds). The system is meant to be scalable, allowing for the application of eDTS technology in a wide variety of vehicles.
“We are ecstatic to be able to demonstrate our technology at Cenex-LCV 2021 and look forward to briefing industry leaders on our systems,” said Nick Grewal, CEO and president of ePropelled. “For the foreseeable future, the battery will continue to be the most expensive component of an electric vehicle. Our technology is far more efficient at utilising battery power, allowing manufacturers to reduce the size of the battery pack by at least 15%. This enables vehicles to be significantly more profitable while still fulfilling consumer demands for range and performance.”
According to the United States Environmental Protection Agency (EPA), transportation accounts for 29% of greenhouse gas emissions, with an average passenger vehicle producing around 4.6 metric tonnes of carbon dioxide per year. Converting to eMobility is critical for mitigating this negative impact. “ePropelled provides technology that not only enables the transition to electric vehicles, but also significantly improves the efficiency of electricity use. There is enormous value in further decreasing greenhouse gas emissions not just from vehicles, but also from power generation and distribution,” Grewal remarked.
Dr. Nabeel Shirazee, CTO of ePropelled, and David Hudson, Head of EV Strategy, will offer a session titled "Using Magnetic Engineering to Improve EV Performance," which will feature results from our benchmark testing. This will take place at 12:30 p.m. on Thursday, September 23, during the session "Power Electronics Machines and Drives."
“The process began with digital twin software simulation tools, progressed to a dyno, and was finally integrated into a vehicle,” said David Hudson, head of EV strategy. “Because the prototype was mounted on an actual EV, the results could be compared to the Bosch motor system used in the original EV drivetrain. We confirmed that our motor is significantly more efficient, and we're excited to present our findings at Cenex.”
“ePropelled had already developed a functional bench-top proof-of-principle system, and the next step was to build a full-scale demonstration vehicle,” Dr. Shirazee continued. As a technology firm, we understand the critical role of innovation and invention in allowing the shift to EVs. We are delighted to be a part of an initiative to create green technologies for the United Kingdom and the rest of the world.”
ePropelled will be exhibiting on both days of the expo at the ARMD stand, #SP-20, and the Wales stand, #C3-117. This technology demonstration is made possible by a funding from the Advanced Propulsion Centre's Advanced Route to Market Demonstrator (ARMD 1025 SEEMS) programme, which is part of a larger effort in the United Kingdom to create green technologies.
