Protean Electric is an award-winning technology company that has developed
an in-wheel electric drive system for hybrid, plug-in hybrid and battery
electric light-duty vehicles. The Protean Drive system can improve vehicle
fuel economy, add torque, increase power and enable improved vehicle
handling to both new and existing vehicles.

Protean Drive is designed for a broad array of vehicles including sedans,
SUVs, pickup trucks and commercial vans – any vehicle with an 18- to 24-inch
wheel. The system also can be added to existing cars and trucks, utilizing
their current internal combustion engine drivetrain. This allows automakers
to create hybrid vehicles in less time and with far fewer changes to the
vehicle design and components.

Protean Electric has designed and developed a unique in-wheel electric drive
system for hybrid, plug-in hybrid and battery electric light-duty vehicles.
A typical passenger car would have two such motors, while a heavy-duty or
high-performance vehicle could have a motor in each of its wheels.

Protean Electric expects its first customers to be Chinese automakers, who
will use the motor in their plug-in hybrids or pure electric cars.

Protean’s system can increase fuel economy by over 30 percent depending on
the battery size and driving cycle. It is also powerful enough to be the
only source for traction on a variety of vehicles. Its ease of integration
can simplify the adoption of hybrid and electrified powertrains across a
broad range of vehicles.

Protean’s in-wheel motors have the highest torque and power density of any
of today’s leading electric propulsion systems. Each Protean Drive in-wheel
motor can deliver 81 kW (110 hp) and 800 Nm (590 lb-ft), yet weighs only 31
kg (68 lbs.) and is sized to fit within the space of a conventional 18- to
24-inch road wheel.

Protean Drive also has superior regenerative braking capabilities, which
allow up to 85 percent of the available kinetic energy to be recovered
during braking. This can increase driving range up to 30 percent and
contribute to the reduction of battery size and cost.

Other benefits include:

Can deliver hybrid and electric vehicle technology faster and with fewer new
parts, less complexity, and at a lower total cost than other leading
electric drive systems

Can be developed as a retrofit application for existing fleets as well as
for new vehicles

Does not require external gearing, drive shafts or differentials

Each motor has a built-in inverter, control electronics and software

Does not require a separate motor power electronics module to be fitted to
the vehicle

Can be added to FWD, RWD or AWD platforms regardless of the fuel type

Avoids costs of unique hybrid drive tooling changes to chassis, bodies and
transmissions

Can help create a hybrid vehicle with fewer changes to the base engine
systems and components and is less disruptive in the assembly plant

Can be a common system for HEV, PHEV and EV vehicles on the same platform
