Inmotive Introduces World's Most Efficient Two-Speed Transmission for Electric Vehicles
PR85730
TORONTO, Sept. 24, 2020 /PRNewswire=KYODO JBN/ --
- Delivers extensive cost savings and extends EV range by up to 15%
- Expertly designed for the next generation of electric vehicles
- Features scalable design for wide range of vehicle applications
Inmotive, a Canadian-based automotive supplier, has launched its patented
Ingear(TM) two-speed transmission(
). Invented and designed for the next generation of electric vehicles, the
Ingear features a simple and durable design that enables a more efficient
powertrain, with extended range, at lower cost.
Inmotive recently completed its extensive pre-production testing of the Ingear,
has integrated it into a demonstration vehicle and is ready for full market
implementation. Test units are available to qualified OEMs.
"This next-generation transmission offers an entirely new way of looking at
multi-speed transmissions for electric vehicles and extends significant
benefits to a wide range of other market segments as well," said Paul Bottero,
CEO, Inmotive. "It is the first two-speed transmission of its kind to be
effectively ready for global market adoption."
How it works
Currently, most EVs use single-speed transmissions, however, equipping an EV
with an Ingear transmission lowers cost, extends range and improves
acceleration times, highway passing capability, top-speed and gradeability.
Typically, there are two reduction gears between the electric motor and the
wheels, with the motor turning about nine times for each revolution of the
wheels. The Ingear replaces the second reduction gear with a continuous chain
drive and a morphing sprocket. To shift, an actuator directs sprocket segments
into place during a single revolution of the wheels, effectively increasing or
decreasing the gear ratio. The Ingear's patented geometry keeps the motor and
wheels in sync, enabling continuous torque flow throughout the shift process(
).
By enabling the drivetrain to operate more efficiently with low and high-gear
ability, less energy is wasted resulting in more range from each charge.
Similarly, regeneration is improved and is continuous, even while downshifting.
"We've found that today's automatic transmissions fall short of what the EV
industry needs," said Bottero. "With an efficient design and substantial cost
savings to the OEM, we believe the Ingear transmission checks all of the boxes
that OEMs have been looking for and will help support wide-spread adoption of
EVs."
Delivering ultimate performance
Key benefits of the new Ingear transmission include:
- Cost Saving – By integrating the simple and low-component-count Ingear
into high volume integrated drive units, OEMs can save more than $1,500
per passenger vehicle. This savings is possible through using less
battery and less expensive electric motors and inverters all while
maintaining the same range and improving acceleration. In addition to
OEM savings, fleet owners will save about $2,000 in operating
(electricity) costs over three years.
- Compact – Designed to wrap around the differential, the Ingear is only
slightly larger than a typical single speed transmission.
- Quick, smooth and quiet – The Ingear shifts in less than a single
revolution of the wheels. The motor is kept in constant contact with the
wheels and can continuously apply torque even during the shift. Gear
ratios change gradually and torque fill algorithms maintain a smooth
passenger experience. Acceleration times can be improved by up to 15%.
- Efficient and reliable – The Ingear extends the range of a typical
vehicle by up to 15% by optimizing motor efficiency and reducing
parasitic losses. It also improves towing, hill-climbing and top-speed.
Technology adoption
Ingear is not a "one size fits all" technology. Its design flexibility enables
OEMs to customize the size and scale of the technology based on the specific
vehicle type. While initial development has focused on the passenger car
market, the technology can be adapted for a wide range of vehicles, including
commercial, off-highway and fuel cell applications.
Inmotive currently has development contracts with two global OEMs and is in
discussion with several other OEMs from around the world for implementation.
