One problem! If you get a flat battery you are going to need some mighty long jumper leeds to get home.

Exactly!! do you not know that 90% of ALL media is owned by only 5 entities? This is how they control public opinion. I'm surprised they're still alive. Tessla died when he tried to prove and market his inventions because they would have destroyed current industries.

the EV1 did not die from lack of popularity

Eh would less pollution be a good enough reason

Thanks ReisendeEuropa I'll look into 'regenerative braking'.

There are so many factors to consider with this. Motor load, wind resistance, mechanical resistance, and the fact that 30% power will still accelerate the car. You use about 2-7% to maintain average highway speeds. A study several years ago showed that a large American pickup truck only needed around 15 horsepower(roughly 12kw) to maintain 55mph. 53kWh/12kW=4.41h run time. At 55mph this equals 242.55mi. I'm guessing this is very close to what the Tesla uses.

well at one third power the vehicle will be using 50kw and the battery capacity is 50kw/hour ie the battery can supply 50kw for one hour.

How would the power run out in an hour when the car goes 244 miles at 60 miles per hour on a charge?
ReisendeEuropa (November 30, 1999 at 12:00 am)
That doesn't work. You simply use the motor as a generator when slowing down. Look up 'regenerative braking'.

By the way this video clip is a bad portrait for an electric car .. The reporter words it very critically like its a novelty that wont catch on . Have they built an alternator into this car to charge the battery up as its being used? |
