Words in the letter Nikola Tesla to his ill mother.

I read the telegram with the news of your death, I despise people who were not ready two years ago to uderstand that an ELECTRIC CURRENT CAN BE TRANSMIT WITHOUT WIRES. Now here are seen to be, but again it will not know for centuries to use...

The BEV electric vehicle project is to develop an entirely new concept: the electric vehicle picks up - sucking electric energy from surrounding space or vacuum   with  non-contact charging method, while either running or standing.

This system is quite advanced in its development phase. With him no longer needs for Lithium Ion batteries of any kind. It should have only the standard low-cost lead-12V battery for the initial start-up vehicles. This battery is before charging from ALTERNATOR, who no longer need, there is a second way in which this battery is charging now.

This is advanced technology known only and made from Nikola Tesla and we adopted as our research and development program for our future manufacturing program for world wide sale of this system.

Nikola Tesla, who was electrical genius and also the inventor of the rotating magnetic field AC motor, polyphase AC power systems, and many elements of radio technology and wireless transport of electric current.

Nikola Tesla conceived the basic principals of the polyphase induction motor in 1883, and had a half horsepower (400 watt) model by 1888. Tesla sold the manufacturing rights to George Westinghouse for $65,000.

The Permanent Magnet Synchronous motor is a rotating electric machine where the stator is a classic three phase stator like that of an induction motor and the rotor has permanent magnets. In this respect, the PM Synchronous motor is equivalent to an induction motor, except the rotor magnetic field in case of PMSM is produced by permanent magnets. The use of a permanent magnet to generate a substantial air gap magnetic flux makes it possible to design highly efficient PM motors. A PM synchronous motor is driven by sine wave voltage coupled with the given rotor position. The generated stator flux together with the rotor flux, which is generated by a rotor magnet, defines the torque, and thus speed, of the motor.

The sine wave voltage output have to be applied to the 3-phase winding system in a way that angle between the stator flux and the rotor flux is kept close to 90° to get the maximum generated torque. To meet this criterion, the motor requires electronic control for proper operation.

For a common three phase PM synchronous motor, a standard three phase power stage is used. The same power stage is used for AC induction and BLDC motors. The power stage utilizes six power transistors with independent switching. The power transistors are switched in the complementary mode. The sine wave output is generated using a PWM technique.

When operated from the 50 or 60Hz voltage, the induction motor operates at a constant speed. However, when power electronics and a microprocessor-based system are used, the motor's speed can be varied. The variable-speed drive consists of an inverter, signal conditioner, and microprocessor-based control. The inverter uses three half bridges in which the top and the bottom switch are controlled in a complementary fashion.

Today, electric car systems are generally fed at 48 Vdc to 330Vdc via rectifier bridges and equipped with modern 3-phase ac traction packages. This allow for easier and more effective implementation of dynamic braking over a wider range of speed and voltage with the possibility of feeding back some of the energy.

The target of this project is to improve the excess energy to the ac side and thus regenerate it, via the transformer, to the dc rectifier and charge additional vehicle battery.

This concept transforms the traditional unidirectional dc traction into a reversible one. It is suitable to all known types of dc traction power supply systems from 48Vdc up to 1,000Vdc. The key benefits expected from reversible dc traction substations are:

Regeneration of 99% of the braking energy at all time, while maintaining priority to natural exchange of energy; this will allow eliminating the braking resistors, and heat release;

Regulation of its output voltage in traction and regeneration modes to reduce losses.

Reducing the level of harmonics and improvement of the power factor on the ac side. Under an ELEKTROAUTO internal R&D programme plan is to built 40Vdc to 1000 Vdc prototypes on a dedicated electric car.

To reduce development time & costs the prototypes were built using state-of-the-art industrial variable speed drive converters, active harmonic filters, high power - semiconductors modules, modern controls and protections, modularity, high integration while taking into account the specific requirements of the electric car industry.

The test results confirmed the theoretical findings and demonstrated that the reversible braking system allowed regenerating all of the excess available kinetic energy of the electric vehicle-car.
