The invention is more efficient in its electrical energy and can cover a longer distance on per charge electric than the present electric vehicles. I'd like to obtain your funding or investment as start-up capital to develop this project anywhere.I have had another invention being more advanced on electric vehicle.Otherwise,If you are not an investor,you may coorperate with me together for developing the project.Of course,I also may discuss redarding licence and/or transfer of my patent with you.
If you have any questions or suggestions,please do not hesitate to contact me.

Cordially,

BACKGROUND OF THE BUSINESS
(MISSION AND GOALS)

The business is an invention relates to an electric vehicle for on-land transportation which is driven by multiple motors that are combined to provide multistep power outputs. The invention has been patented (U.S. Patent No. 6,105,696 (issued August,22 2000).

Most automobiles in current use are driven by fuel engines, which experience a great deal of mechanical loss and have low energy efficiency(it is about 11% on road of city meanly,it is will be more low if consider other reasons for example about 70% of four-sites vehicles are only one driver), thereby consuming a lot of energy and causing environmental pollution and also the fuel vehicles are adding fast-stepping to bring about more and more hothouse air resulted in global weather abnormality-change. Moreover,petroleum that fuel vehicles used up is as un-renewable resource will be less and less till extinction in the future shortly.
Current electric vehicles are currently adopted sole electric motor also have low energy efficiency and consume a great deal of electricity. The power capacity of current accumulator batteries
does not allow current electric vehicles to travel long distances, so that they are not very practical.An electric vehicle with sole electric motor was tested and proved its energy changeover efficiency are commonly about 26% at 40km/h,58% at 60km/h,72% at 80km/h,when used a electric motor that is 93% of the best efficiency.

SUMMARY OF THE INVENTION AND IMPLEMENTATION

The object of the present invention is to provide a new type of electric vehicle with combined motors of multistep power outputs which is energy-saving, can travel continuously longer distances, and does not pollute the environment.

These objects of the present invention are achieved by using a set of accumulator batteries as a power source and by using multiple combined motors with different powers to drive the electric vehicle, where each motor has its own circuit system and switching device. The motors can be switched either simultaneously or separately by using juxtaposed switching pedals. When these motors are actuated simultaneously, the greatest
resultant force is produced and the maximum power output is obtained. When only the large power motor is actuated, a relatively high power output is obtained. If only the small power motor is actuated, the lowest
power output is obtained. This arrangement gives the electric vehicle multistep power outputs whose number is more than that of the motors, whereby the different power output steps can be employed according to the magnitude of resistance during traveling. For example, if the electric vehicle is accelerated when it first starts moving, multiple motors are actuated
simultaneously, thereby obtaining the highest power output. After accelerating, as the inertial force increases and resistance relatively decreases, the power output of the motors can be progressively reduced until finally the small power motor alone can either accelerate the electric vehicle or maintain it traveling at a constant speed. In order to make it possible for the output power of the small power motor to effectively propel the vehicle, the maximum r.p.m. imparted by the motor to the driving shafts should be higher than that imparted by the large power motor. The clutches between the motors and the driving shafts act to improve the starting performance of the vehicle, such as by reducing frictional resistance and balancing the vehicle speed.

By means of the arrangement of the present invention, it is possible to utilize inertial force sufficiently, increase energy conversion efficiency, lengthen the time and distance of continuous travel, reduce environmental pollution, lower the cost of driving, and make driving more convenient.

The scope of this development will be to implement the multistep electric motor functions into a road worthy passenger vehicle. Also, in this phase, larger scale proto type multistep motors will be implemented in a
vehicle simulating the weight and inertial forces of a commercial bus. It is Applicants belief that this invention will support short haul heavy vehicles up to and including commercial busses, two to three ton
delivery vehicles used by firms such as the U.S. Post Office, UPS and Federal Express and other some custom vehicles,like ambulance.
TECHNOLOGY & INNOVATION:

Abstract

An energy-saving and high-efficiency electric vehicle which uses a set of accumulator batteries as a power source and is driven by multiple motors of different powers, each motor having its own circuit system and switching device. When greater resistance is
encountered by the vehicle, such as when it starts or is going uphill, the large and small power motors are
actuated simultaneously to provide a resultant force. After starting, when inertial force increases and resistance relatively decreases, the small power motor alone can be actuated, but the maximum r.p.m. it can
impart to the driving shaft should be higher than that imparted by the large power motor. In this way it is possible to save energy, thereby lengthening the time and distance of continuous travel of the vehicle. At
the same time, the vehicle is of lower cost, is convenient to drive, and does not pollute the environment.The targeted applications will be passenger vehicles and two to three ton delivery vehicles and commercial busses.The patent tech also can use with fuel cell vehicles and hybird electric vehicles.

The ordinary skill engineer think that an EV only need a motor and can achieve better effect but actually almost of EVs made by somebody in the U.S. or Japan with having to settle a cold system (oil,water or/and wind)for its motor and controlor or else they will be overheat or even fire.The reason is that electric energy have a large of loss due to both input power of motor and requirement power of EV don't balance.It is known as that most of machines didn't need coal system (wind,oil or water)for motor and controlor because both powers above can be balanced almost and e-energy loss is very small and this is the purpose of the patent pursued.Due to don't need the cold system and improving EV bodywork can make its air resistance power being reduced over 60%.

EMISSION BENEFIT:

This invention technology can make electric vehicles more affordable as battery requirements and weight will be greatly reduced. It will increase the
percentage of zero emission vehicles in all of vehicles.The fuel vehicles will be reduced greatly on road. The final goal of the invention is to take zero emission vehicles up to 50% in all of vehicle's market share and 70% in drive rate on road. At such levels, overall emission will be reduced up to 70%.

ECONOMIC AND COMMERCIAL POTENTIALS:

At present,the sales volume of market is $300B per year in the US. The electric vehicles using the invention will approach that sales volume of
potential market is $100-200B per year in the US at final goal. The multistep motor technology will immediately gain market share as manufacturers find that battery weight, size and power issues are lessened significantly.
The application of the technology to busses and light delivery trucks will hit squarely the vehicles whose emissions are the hardest to limit in commercially economically ways. Users such as Federal Express, UPS
and the U.S. Government will be candidate sponsors in the commercialization phase.
The estimating revenue will be about one billion USD. and the estimating profit will be about 200 millions USD. in the future for three years.

PROJECT DESCRIPTION:

The project will encompass the implementation of the multistep motor into passenger and light truck vehicles. Tests and analysis will be undertaken
top optimize motor strength and structure to vehicle weight and required power and speed. The final technology goal of the invention is to maximize electric energy in terms of kw/h driving for electric vehicles weighing 1000kg driving 30km. For example, an electric car will drive approximately 200km(100km on highway & 100km on down town road) using
ordinary battery and 300km(200km on highway & 100km on downtown road) using better battery on single
charge. Also, all of technology functions of the electric vehicle will approach or surpass fuel vehicles at present.
