ReGenXtra Inc. ReGenX Demonstration during EVS 29 June 2016
• The electric vehicle (EV) Regenerative Acceleration (ReGenX)
innovation employs a Load Current Delay in order to reverse the electric vehicle regenerative braking paradigm and allow for continuous battery recharging during all modes of EV operation.
• ReGenXtra has conducted significant R&D on the ReGenX innovation since the original Regenerative Acceleration discovery in 2007.
• This demonstration incorporates three different prototypes.
• Each one has been built to showcase the various aspects of the Regenerative Acceleration innovation.
ReGenXtra Inc. ReGenX Product Demonstration during EVS 29 June 2016
The three demonstration prototypes include the following: 1. ReGenX Generator Prototype #1: • Incorporating a conventional generator coil and a ReGenX Generator coil
placed on the same core, • highlighting the Load Current Sine Waves of each coil . • Conventional generator coil regenerative braking, • and Regenerative Acceleration as caused by the ReGenX Generator’s
Load Current Delay. 2. ReGenX Generator Prototype #2: • Operating above and below the ReGenX coil’s Critical Minimum
Frequency. 3. ReGen-X Motor Prototype # 3: • Demonstrating ReGen-X Motor action with simultaneous ReGenX
Generator action.
Demonstration Prototype #1 EV Regenerative Acceleration Generator
Load Current Delay
ReGenX Generator prototype #1 incorporates :
• a conventional generator coil and a ReGenX Generator coil
• Both coils are placed on the same core and influenced by the same rotor magnets at the same time.
• This prototype showcases how and why the Regenerative Acceleration phenomenon is produced.
• The ReGenX coil Load Current is delayed by approximately 45 degrees.
• This Load Current Delay as demonstrated on the oscilloscope is responsible for EV Regenerative Acceleration because delaying the coil’s load current also delays the coil’s induced magnetic field and how and when this induced magnetic field affects the rotor.
Demonstration Prototype #1 EV Regenerative Acceleration Generator
Load Current Delay
• EV Regenerative Acceleration Generator Load Current is delayed by 45 – 70 degrees.
• Conventional generator coil’s load current Sine Wave is shown in yellow on the oscilloscope. • The ReGenX Generator coil’s load current is shown in blue. • After the conventional coil’s load current peaks (center line on the oscilloscope), the rotor magnet begins to move away from the coils. • The ReGenX Coil’s Delayed Load Current produces a Delayed Induced Magnetic Field which assists the rotor magnets departure.

PERFORMANCE DATA
EV Regenerative Acceleration Generator
Demonstration Prototype #2
• Operating Below the Critical Minimum Frequency • The primary factor dictating Regenerative Acceleration performance is frequency of operation
because frequency of operation dictates the coil’s Impedence from the equation:
ZT = XL + RDC
where the coil’s Inductive Reactance is:
XL = 2 π F L such that:
ZT = 2 π F L + RDC
• When the coils operational frequency (F) is increased the coil’s impedence (ZT) also increases. • When impedence increases load current flow decreases and if ZT is high enough load current flow ceases
altogether. • When load current flow ceases the ReGenX coil cannot store energy in the Electromagnetic Field around
the coil as an inductor and is forced to store energy Electrostatically inside the coil as a capacitor. • When the induced voltage in the ReGenX coil exceeds the dielectric's ability to store it – the dielectric
breaks down and load current begins to flow - but the delay has already occurred and the ReGenX coil’s Delayed Load Current peaks when the rotor magnet is now moving away from the coil.
• The result is the receding rotor magnet ‘s departure and the approaching rotor magnet’s approach are both accelerated in the process while load current is delivered to the EV’s batteries without deceleration of the EV.

EV Regenerative Acceleration and Regenerative Braking
• When the ReGenX Generator is operated above the ReGenX coil’s Critical Minimum Frequency in Regenerative Acceleration Mode the system accelerates on load and the torque supplied by the prime mover decreases as the EV’s batteries are recharged.
• When operated below the Critical Minimum Frequency in regenerative braking mode, the system decelerates as the EV’s batteries are recharged.
Demonstration Prototype #3 EV Regenerative Acceleration Motor
• ReGen-X Motor • A single coil motor prototype that delivers Mechanical Output
Power and Electrical Output Power.
• The ReGen-X Motor showcases EV Motor operation simultaneously with ReGenX Generator action (i.e. battery recharging during motor mode/EV acceleration).
• The Regen-X Motor prototype demonstrates how the ReGen-X Moror’s input current (that is responsible for creating the motor’s torque and accelerating the EV) can also be returned to the battery and recharge the battery at the same time.
• This is achieved because the ReGenX Generator creates a Complementary Electromotive Torque that is manifested in the same direction as the motor coil’s torque.

The ReGen-X Motor circuit allows for the
input motor current to be used to establish
magnetic field around the ReGen-X Motor
coil as per conventional motor operation.

To collapse back into the coil and back into the
EV’s batteries in tandem with ReGenX Generator
action (Complementary Electromotive Torque).

• The EV Regenerative Acceleration (ReGenX) innovation now allows for continuous EV battery recharging during all modes of EV operation.
• During EV acceleration, coasting, and during braking.
• EV range extension is dictated by the magnitude of Regenerative Acceleration recharge current supplied by the ReGenX unit.
• EV battery size and storage capacity is no longer a determining factor with regards to EV range.
