the dark secret of electric cars: astounding speed

When John Waters challenged them to take part in the race, his colleagues at GM thought he was joking: their high-power frigates had nothing to do with his EV1 except the electric motor.
EV1, the first electric vehicle made by GM, is a good one-
It looks compact, but it looks a bit like a shy bug when parked next to Corvette.
Waters has a rule.
The race must take place in the parking lot, which limits the maximum speed to about 30 miles per hour.
Frequent competitions have caused a sensation to some extent, especially among high school students, who will flock to the scene to see the powerful slaughter of the weak.
Did waters win?
\"We have never lost a game,\" he said . \"
\"Of course, Corvette has more horsepower, so if we run from zero to 100, they will smoke us.
\"The secret behind the success of water is that he believes that electric cars will overcome the interior --
In future cars, internal combustion engines may not be far away in the future.
GM speeds up in quality

The operating efficiency of electric vehicles is about 30%, and about 70% of the energy is consumed by the heat, sound, friction and pollutants that destroy our atmosphere.
According to Waters and many studies, a vehicle driven by an electric motor can operate with an efficiency of about 90%, as instant power is obtained through torque.
The gas engine moves the piston and turns the crankshaft of the rotating flywheel by igniting the fuel, eventually causing the wheel to turn, thus converting the energy into motion.
But at low speed, the engine does not have enough torque. -
Forward motion generated by rotating motion-
Let the vehicle go.
Therefore, all energy must be helped by the transmission, which allows the engine to rotate faster to make the car move and slow down as the speed increases.
The motor does not need all the help, including the complex, heavy and expensive transmission found in today\'s natural gas --powered cars.
It gets as much torque from rest as at high speed.
This is the so-called \"instantaneous torque\", which is the reason for the water toy --
Like a car can blow High
Performance vehicles, at least from zero to 30 miles per hour.
That\'s part of the reason some of the fastest cars on Earth are now driven by electric motors instead of the interior.
There has been an internal combustion engine for more than a century.
\"Experimental electric vehicles have reached a sustained speed of more than 180 miles per hour and created a world speed record of more than 300 miles per hour, earlier this month, waters said at the National Conference of the American Society of Chemistry.
Tesla Motor announced plans for self-driving, he developed a battery platform for EV1 during GM\'s work, and is expected to show the amazing performance of electric vehicles on the track soon.
\"I have no doubt about the battery --
\"Electric Racing will attract racing enthusiasts in the near future,\" he told ACS . \".
The high performance of electric vehicles has been overshadowed by two major factors: range, because no one wants to run out of juice halfway through work, as well as expensive batteries, which are heavy and require frequent charging.
Through the natural development of new technologies, some problems will disappear, such as faster charging, more remote charging locations, and more juice in the battery. The state-of-the-
The art of battery technology is lithium.
Researchers all over the world are frantically trying to improve their performance.
No battery can match the energy in a gallon of gasoline, which is called the energy density of the material.
This obviously has to change for electric vehicles, with new \"breakout\" reports coming up almost every day.
Just last week, the University of Colorado at Boulder claimed that it could now double the range of cars powered by lithiumion battery.
Today\'s batteries, from mobile phones to high-performance cars, generate electricity by moving ions. -
Charged particles-
Move back and forth between the two electrodes in the liquid electrolyte solution.
Researchers in Colorado say they have found a way to replace liquid electrolyte with solid
State systems with greater energy density in which ions move through solid ceramic electrolyte and they have the money to bring the technology closer to \"becoming a commercial reality \".
\"If that\'s the case, it\'s a serious thing.
Meanwhile, researchers at the Department of Energy\'s Oak Ridge National Laboratory in Tennessee claim that lithium is being produced-
Sulfur cell, which has four times the energy density of conventional lithiumion battery.
The main purpose of this study is to provide better batteries for small necessities in life-
Mobile phones, laptops, etc. --
Some jobs are really shocking.
Engineers at the University of Illinois at Urbana
Champagne announced in April that they have developed small \"micro-batteries\" that can make a huge impact. How huge?
Say the boot battery on your gas-
The power car is dead.
You can jump over with your phone.
Start the engine, according to researchers in Illinois.
It is best to start quickly, because only a few mm-sized batteries can\'t run out so much power for a long time.
Once you start using this old beast, you can drive it all over the country without worrying about charging.
Gas stations are everywhere.
This is not the case with electric vehicles.
Everything charming
Electric Tesla sports cars may be able to drive at 125 miles per hour, but without charging you can\'t drive from Los Angeles to San Francisco, which can take a whole night.
Scientists at MIT and Stanford have been working on a way to transmit electricity wirelessly.
This may make it possible for electric vehicles to charge while driving on the highway.
The researchers said the copper coil can be embedded in the highway, generating a magnetic field, generating current in the matching coil in the vehicle, thus charging the battery.
The two sets of coils will operate at the same frequency, and only at that frequency, so that one can lie on the highway and not be harmed by the energy being transferred from the ground to the car.
Of course, all of this doesn\'t work, but it\'s been a big step since GM first made that beautiful little car in 1996 and wiped out those Corvette.
EV1 was leased to drivers in several states in a pilot project, but GM gave up the project when it turned to other electric vehicle projects, although many drivers enjoyed the car.
Some even threatened to sue if GM had recovered the cars, but by 2002 all the cars had been returned to the manufacturer.
Most were crushed, some were sent to the museum, all but one were disabled and no longer a threat from Corvette.
The only survivors are at the Smithsonian Institution.
