bill vance: general motors’ ev1 was far ahead of its time  -  car power window
When GM unveiled the Impact electric concept car in 1990, it knew that the era of electric vehicles was coming.
This is another step in the history of trying to promote a successful electric vehicle, which is an exploration back to the embryonic stage of the car.
While electricity and steam were indeed briefly welcomed in the early 20 th century, gasoline soon took over.
The short-distance mileage of electric vehicles largely limits its driving in the city, and the mileage is still the limit of electric vehicles.
We are referring to cars driven by electric motors.
Board battery charged from external power supply.
This is not confused with gasoline/electric hybrids such as Toyota Prius, or even early Ontario hybrids --
His gasoline engine charges the electric motor.
The power impact of General Motors is partly by the California Aviation Resources Commission (CARB)
The legislation stipulates that by 1998, two of all cars sold in California had zero emissions, reaching 10 per cent by 2003.
Carbohydrates easily ignore the fact that charging usually comes from fossils --
Fuel power plants.
The "98 year 3 Day" law is a classic case of legislation trying to push technology, and it is abandoned when it proves impractical.
Despite the history, GM still insists and launched the EV1 in 1996 (

Due to the deterioration of battery power as ambient temperatures drop, GM is only available on lease in the Los Angeles, San Diego, Tucson and Phoenix regions.

The seats are very compact, only 4,310 long on 2,512-mm wheelbase.
It's only 1,283mm high.
The real downside is that the weight is 1,361, which is another electrical disadvantage, contributed by 533
12-26 kgvolt lead-acid batteries.
The front wheel of the Ev1 is driven by an AC motor with a rated power of 137 hp, with a speed from 13,000 to rpm.
The torque is 110-
The foot develops from zero to 7,000 rpm.

According to the car and the driver, EV1 is very quiet and performs very well.
They recorded 0 to 100 km/h in 8 hours. 4 seconds.
The maximum speed is 129 km/h.
The usual mileage limit for electric vehicles still exists. The U. S.
EPA rated EV1 on Highway 146 km and 129 km cities.
The "Real World" range observed by C & D is 96 km.
The process of starting is relatively simple. Enter a five-

The fuel gauge is a charging indicator that shows the distance remaining when the battery is in use for a few minutes before driving.
EV1 is charged in about 14 hours by plugging in a home power supply that gives a small on-

A faster way is for GM's "Magne charging" charger, which is charged in less than three hours and must be leased from GM.
A small amount of energy is recovered through on-
When the motor is temporarily converted to a generator, the plate is recharged during taxiing and braking.
EV1 received a gentle response from the public.
Some EV1 drivers are very enthusiastic, but the general public yawns.
The absorption was too slow and the car began to pile up on the lot of dealers.
Finally, in 1999, GM stopped EV1 after building about 1,000 vehicles.
It, like Toyota, found that people have limited interest in cars. electric car.
In 2006 Sony films, Michael Moore made a "documentary" called "Who Killed the Electric Car "?
The "villains" quoted in the death of ev1 include General Motors of the United StatesS.
The government is even carbs.
The real killer seems to be the public indifference.
Most people are not interested in paying extra for a car that might leave and then run aground, and have an exercise range equivalent to about two gallons of gas.
Progress in battery technology is gradually overcoming this disadvantage.
