ePropelled, the Massachusetts-based technology company that offers leading-edge electric propulsion systems, today announced the release of a groundbreaking new electric vehicle (EV) propulsion system to be showcased at the Cenex-LCV in Millbrook, U.K.
This new system increases power efficiency by at least 15%, which will allow manufacturers to reduce the size and cost of their battery packs. Battery packs can account for as much as 30% of the cost of vehicles, which can make smaller EVs uneconomical. Reducing this cost will improve profitability of EVs while facilitating adoption by consumers.
ePropelled’s Dynamic Torque Switching™ (eDTS) uses an innovative software-controlled reconfigurable propulsion motor that is the foundation of a complete EV propulsion system. eDTS allows the electric motor to provide high torque at low speeds without drawing high currents from the batteries.

It also provides high speeds at low torque levels without using field weakening, thereby increasing the efficiencies throughout. eDTS is a scalable design that can be used in a variety of electric vehicles ranging from light EVs, such as scooters and three-wheelers used in last-mile delivery, to cars and trucks.
This patented technology is a drive system concept that allows a single electric machine to dynamically change between several modes to provide a much broader range of high efficiencies for low power consumption. The control system is designed to allow the transition between the modes to take place seamlessly to deliver optimum torque, speed, and efficiency characteristics in real-time.
The technology company will reveal and display its innovative electric motor technology in the ARMD stand, #SP-20, and the Wales stand, #C3-117, at the Cenex-LCV 2021 show in Millbrook on September 22-23.
ePropelled worked with Tata Motors with support from Embed, Ltd. to install the eDTS system in a Tata Tiago, which will also be on display at the Cenex-LCV conference. This version of the new propulsion system generates 60 kW of continuous power and up to 180 kW of peak power (for 10 seconds). The system is designed to be scalable so eDTS technology can be used in a wide range of vehicles.
According to the U.S. Environmental Protection Agency (EPA), the transportation sector accounts for 29% of greenhouse gases, with a typical passenger vehicle emitting about 4.6 metric tons of carbon dioxide per year. Transitioning to eMobility is essential to reducing this negative impact. “ePropelled delivers technology that not only enables the migration to EVs but also uses electricity much more efficiently. There is tremendous value in further reducing greenhouse gases not just from vehicles but also upstream from the power generation and grid,” Grewal said.
