The Future and how gensis is already there

Electric vehicles are not a new idea and in fact were prevalent and preferred before the arrival of the internal combustion engine. DC and AC motors were also invented much before the internal combustion engine, but were superseded because of range and power density to weight constraints at that time .You may ask why gensis is using DC rather than AC motor drives or that we are not using permanent magnet motors or sepex and a myriad of other designs, quite simply because there is a fundamental advantage to DC series wound motors. 


Torque or the ability to twist a shaft with the extraordinary  power to weight ratio of a DC motor. Launching a road vehicle from a standing start and accelerating cannot be equaled by any like for like AC motor regardless of claims because material  and pure physics does not support it.


gensis has begun to produce electronic systems to control vehicle DC motors, what we are offering technically is a standard implementation of a DC drive but with an infinitely variable frequency to load shifting algorithm. This is the drive you buy from us and no one else, today


This improves efficiency, improves cooling and gives greater range, greater range than AC systems with the same battery capacity.


Under development is a new carrier frequency shifting DC controller with anti acoustic wave injection into the motor winding to  silence the DC motor by preventing winding vibration, The ultra fast modulated DC fundamental prevents the DC motor becoming a tuning fork and ringing with the predictable DC motor noise. Near silent operation of a DC motor will be a worlds first.


So why do our controllers not have regen (regenerative braking or power conversion from mechanical to electrical voltage) ?

 

The answer is they do, but they do not use the main DC drive motor. Using the main series drive motor for regen has not been implemented long term successfully to our knowledge.


Under development is an ultra lightweight generator that is purposely designed for intermittent operation. Using aircraft building techniques, the power conversion density is a magnitude higher than a commercial DC series wound traction motors and the generator initially will be connected to a double shaft DC traction motor to provide 30% maximum regen,  perfect for city streets, long hill descents would be assisted by braking resistors (already an option today).


Also under development and delayed because of the current software development load is the vehicle exchange information VEI for short.


What does it do? It talks to other gensis equipped vehicles on the road within 100 metres and exchanges information on the upcoming road conditions regarding temperature, climbs, descents, vehicle density's and average speeds and braking averages.


It does not give data on location or destination of the vehicle but parameters that assist the controller in adapting the correct mode of operation and informing the driver of required avoidance or change in driving style. It can be turned off or on by the driver.

 

So the future is here, all the above will be available during 2017. What else is going to be available?


We can only tell you a year in advance for commercial reasons,  but we have ten years of advances already in development.
