eCycle's hybrid supercharger consists of a SolidSlot™ brushless motor/generator and an Ogura (or comparable) compressor.  The supercharger is a practical bolt-on machine that increases efficiency and performance, while reducing emissions on a variety of engines in automotive, mass transit, truck and marine platforms. 

Unlike conventional belt driven superchargers, the Hybrid Supercharger is driven by a SolidSlot brushless motor/generator that delivers instant boost, independent of engine rpm.

Hybrid Vehicle Configuration

There are two commonly accepted methods for hybridization, series and parallel. A series hybrid employs a distinct gen-set for battery charging and powering of one or more traction motors, with no mechanical coupling of engine and wheels. A parallel hybrid is an engine-based powertrain bolstered by a motor/generator and controls with a supporting battery bank. In both examples, high voltage is employed for on-road application to provide sufficient performance.

A hybrid supercharger is similar to a conventional belt or gear driven unit, except that a brushless motor powers the compressor, and it can therefore be operated independent of engine speed, mainly to increase low-end torque. Because a supercharger enhances the engine by delivering more air to it, well established techniques for control – fuel injection and ignition – are utilized.

Importantly, a hybrid supercharger need only apply a small portion of traction power to the engine via compressed air, in order to achieve comparable output to other hybrid configurations. This affords a low battery bank voltage, with inherent advantages in cost and complexity. The system can be readily recharged while the vehicle is cruising, and
also from an electrical outlet when parked, thereby creating a low cost plug-in hybrid, given the use of suitably sized batteries.

In summary, vehicle hybridization is an accepted means of increasing fuel efficiency and reducing emissions. Today’s hybrid vehicles supplement a gasoline or diesel-fueled internal combustion engine with an electric motor/generator to provide traction.
