HYBRID AND FUEL CELL VEHICLES

The 4QMET is a transmission that enables a motor to always operate at a constant speed and at the motor’s peak efficiency, while providing controlled output speed and torque conversion. Conversion of constant motor speed to variable output speed and torque is accomplished electronically. Unlike mechanical CVT’s, no external power is required to perform the conversion. Therefore all efficiency benefits are fully captured in energy savings.

The picture below shows the 4QMET mounted in a vehicle powered by a single electric motor. The source of power for such a vehicle could be a fuel cell, or in today's applications, a hybrid power source (e.g. small gas powered engine powering a generator). Use of the 4QMET significantly improves efficiency of operation resulting in dramatically lower energy consumption.


The 4QMET's advanced architecture can be used for a 4 (or 2) wheel drive electric motor powertrain. Automotive companies are moving towards this type of powertrain in which mechanical linkages are eliimnated and replaced by electronic control of speed and direction. The benefits of this approach include full time all-wheel drive and elimination of the differential. The image below shows the implementation of the 4QMET in a 4 wheel configuration. Each motor is connected to its wheel via a 4QMET (scaled in size to the power requirement) controlled by a master 4QMET controller.
