We believe we have overcome one of the primary barriers to cost-efficient larger or faster vehicles. Electric Vehicles so far have a widespread reputation for being low powered and slow compared to combustion vehicles of the same type. This is because larger or faster vehicles require bigger, higher powered motors and higher voltage batteries. For EVs, an increase in power has traditionally meant an exponentially disproportionate increase in cost; e.g. while a 15 Kw Multilayer BLDC motor costs approximately $2,000, a 60 Kw motor costs around $20,000. Our Multi Motor System (“MMS”) solves this problem by using four 15 Kw motors instead of one 60 Kw motor. Costing around $8,000, it outperforms the 60 Kw motor at less than half the cost.
Other than cutting the costs, however, the MMS also dramatically improves efficiency, power, and safety. One benefit of multiple motors is that it distributes power sources among four motors, generating greater wheel power than its single motor equivalent. Another is the dramatic energy saving potential of being able to operate anywhere from one low powered motor to all four, depending on the driving mode. After accelerating to desired speed using the increased torque of the MMS, the EV can switch off all but one small motor to expend the minimal amount of energy needed to maintain cruising speeds. Also, our system results in changing the high voltage system of larger and faster EVs to a low voltage system, 360V to 72V, which reduces energy consumption even at full power.
Finally, the MMS increases EV safety by reducing the risks involved with a motor breakdown. Much like a multiple engine jetliner, when something goes wrong with one of the motors, the other three are able to keep working and get the driver to safety.
Once our intellectual property rights to this technology are secured, we plan to market the MMS to EV and PHEV makers throughout the world. We believe this system will lead the high voltage vehicle motor market.
We have recently invented what we believe is the most advanced power motor technology in the world: the Multilayer Brushless DC (“BLDC”) motor. Prior to the Multilayer BLDC, the most advanced power motors with the highest power and energy efficiency have included the single layer BLDC and the Brushless Permanent Magnetic AC (“BL PMAC”). The chronic problems of motors used in EV would experience a significant drop in magnetic power and would lose power and efficiency in doing so.
Our Multilayer BLDC has many magnetic or copper layer instead of one, and so it does not lose magnetic power after a sudden power increase, as do existing motors. Our motor can achieve more than twice its original power when extra power is needed. In addition, the Multilayer BLDC has the added capability of electricity regeneration: using the wheels, it can regenerate approximately 10% of its expended electricity, leading to longer road life.
We believe our Multilayer BLDC motor could improve even the highest end EVs, including supercars such as the Tesla Luxury Electric Sports Car. Accordingly, we expect to market our motor to other EV makers, as well as makers of Plug-in Hybrid EVs (“PHEV”), and intend to begin mass production in early 2009.
