ePropelled’s innovative EV propulsion system…

ePropelled, the Massachusetts-based technology company that offers leading-edge electric propulsion systems, has launched a groundbreaking new Electric Vehicle (EV) propulsion system. 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 current 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 system has been designed to be scalable.
