ePropelled, the Massachusetts-based technology
company that offers leading-edge electric propulsion systems, has 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 profitably of EVs while facilitating adoption by consumers.
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.
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.
technology company will reveal and display its innovative electric motor
technology in the ARMD stand 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.
version of the new propulsion system generates 60 kW 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.
are very excited to be able to showcase our technology at Cenex-LCV 2021 and
are looking forward to briefing industry leaders about our systems,” said Nick
Grewal, ePropelled’s CEO and president, adding that, “For the next few years,
the battery will remain the most expensive component in an EV. Our system uses
battery power much more efficiently, which will allow a manufacturer to reduce
the size of the battery pack by at least 15%. That will enable vehicles to be
much more profitable while meeting consumer expectations for range and
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 year1. Transitioning to eMobility
is essential to reducing this negative impact.
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,” added Grewal.
